'''Professor E. Gadd''', also known by his full name '''Professor Elvin Gadd''' or simply '''E. Gadd''', is an elderly scientist who debuted in ''[[Luigi's Mansion]]'' and is the founder of [[Gadd Science, Incorporated]]. He is a researcher of [[Ghost (Luigi's Mansion series)|ghosts]] and is responsible for a variety of inventions, most notably the [[Poltergust]] series of vacuums. He makes ambiguous gibberish sounds when speaking (supplied by [[Kazumi Totaka]], who took inspiration from ''[[:Category:Animal Crossing series|Animal Crossing]]''{{'}}s "[[nookipedia:Animalese|Animalese]]" when inventing the voice<ref>{{cite|author=JC, Anthony|date=September 2001|deadlink=y|archive=web.archive.org/web/20071014103505/http://www.n-sider.com/articleview.php?articleid=414|title=The Making of the Game - Luigi's Mansion|publisher=n-sider.com (translation from ''Nintendo Online Magazine'')|accessdate=August 28, 2020}}</ref>), and he frequently uses phrases such as "criminy," "hullabaloo," etc. His name comes from the exclamation "egad," a {{wp|minced oath}} for the archaic expletive "ye gods."

===Background===
[[Elvin Gadd (past)|In his past]], E. Gadd lived on the foothills of the [[Thwomp Volcano]], as depicted in ''[[Mario & Luigi: Partners in Time]]''. The Mario Bros. go back in time and end up saving his lab from burning down when fire blocks erupted from the Thwomp Volcano. He then helps the Mario Bros. by inspiring his older present self to create the [[Hydrogush 4000]]; as the Mario Bros. are in the present, he starts to get the idea for the device, which transfers to his future self. The present-day Professor E. Gadd uses the Hydrogush 4000 to send water through via [[time hole]] and calm the erupting Thwomp Volcano. Afterwards, E. Gadd moves to [[Boo Woods]] when he was around twenty-years-old, where he would later study ghosts.<ref>{{cite|quote=I've been living here since I was a lad of twenty or so [...]|author=Professor E.

The Mario Bros. go back in time and end up saving his lab from burning down when fire blocks erupted from the Thwomp Volcano. He then helps the Mario Bros. by inventing the [[Hydrogush 4000]]. Although he doesn't directly invent the Hydrogush 4000, his older self does in a complex way: Young E. Gadd starts to get an idea after a totally unrelated event happened during the present time, which transfers to his future self, causing the present-day, elderly professor to send water from the Hydrogush 4000 via [[Time Hole]] and calm the erupting Thwomp Volcano. After all this excitement, the twenty-year-old E. Gadd moves to [[Boo Woods]], where he would later study ghosts.<ref>In ''Luigi's Mansion'', E. Gadd stated that he lived in [[Boo Woods]], in order to research Ghosts, since he was 20.</ref>

Many decades later, in ''Luigi's Mansion'' and its [[Luigi's Mansion (Nintendo 3DS)|remake]], [[Luigi]] enters the mansion and is saved from a [[Gold Ghost]] by Professor E. Gadd wielding the [[Poltergust 3000]], as shown in a cutscene. The professor reveals that he lives in a house near the mansion, where he researches his favorite subject: ghosts. Luigi explains his brother [[Mario]] is missing within the house, and the professor decides to help Luigi by giving him the Poltergust 3000 and the [[Game Boy Horror]]. The professor continues to help Luigi throughout the game, giving him help and tips.

After a few years of absence, Professor E. Gadd appears in ''[[Luigi's Mansion: Dark Moon]]''. In the game, E. Gadd takes up residence in [[Evershade Valley]] after learning that the ghosts there are friendly due to the effects of the [[Dark Moon]] that hangs over there pacifying them. Eager to examine ghosts without fear of being attacked by them, he sets up a laboratory in the [[Gloomy Manor]] and a [[Bunker]] close by the mansion. There, he begins researching the ghosts of the five mansions that populate the valley and sends his five [[Toad (species)|Toad assistants]] to the other four mansions in the valley to examine the ghosts there. At first, the resident ghosts welcome him and assist him in [[Lab (Luigi's Mansion: Dark Moon)|his lab]], but when King Boo arrives and destroys the Dark Moon, the ghosts start running amok and destroy E. Gadd's equipment. He flees to his nearby Bunker and enlists the help of Luigi &mdash; who has now taken up residence in his new [[Luigi's NEW Mansion|Grade D mansion]] from the previous game &mdash; to help rebuild the Dark Moon and calm the ghosts once more. E. Gadd was later revealed to have been unintentionally and indirectly responsible for King Boo's return, as he had sold his portrait in a garage sale (a car boot sale in the British English version), thus ensuring his escape.

In this game, E. Gadd has made an upgrade of his Poltergust 3000 from the last game: the [[Poltergust 5000]]. This new Poltergust uses a [[Strobulb]] to stun ghosts, rather than the flashlight used with the Poltergust 3000. Professor E. Gadd also introduces three new inventions: the [[Pixelator]], a machine that turns Luigi into pixels and transports him to and from the different mansions, the [[Dual Scream]], a device that resembles a [[Nintendo DS]] and is capable of communication, and the [[Dark-Light Device]], which allows Luigi to see invisible objects. He does not leave the Bunker until the end of the game, directly after beating King Boo.

===''Super Mario Sunshine''===
[[File:E Gadd with Poltergust LM3 art.png|thumb|Professor E. Gadd in ''Luigi's Mansion 3'' with the [[Poltergust G-00]]]]
Although Professor E. Gadd does not appear in ''[[Super Mario Sunshine]]'', when Mario initially finds [[F.L.U.D.D.]] at the [[Delfino Airstrip]], it says, "Thank you for purchasing this item from Gadd Science, Inc.". Later, [[Bowser Jr.]] says he got his [[Magic Paintbrush]] from "a strange old man in a white coat." Bowser Jr. uses the paintbrush to frame Mario and get him away long enough for himself to go in and kidnap Princess Peach. This is a fitting description of Professor E. Gadd, which is further confirmed when F.L.U.D.D. seems to react in surprise to the statement. Bowser Jr. claims E. Gadd gave the brush to him of his own free will and that he didn't know the professor's name when he received the brush, but it's unknown whether this is true or not. There is a symbol on both the Magic Paintbrush and F.L.U.D.D. showing a face and hairstyle similar to E. Gadd's, which seems to be the Gadd Science, Inc. logo. It appears on many of E. Gadd's other inventions, as well as the [[Nozzle Box|boxes for F.L.U.D.D.'s nozzle upgrades]].
E. Gadd returns in ''[[Luigi's Mansion 3]]''. Having been tricked by [[Hellen Gravely]] into visting her hotel, [[The Last Resort]], E. Gadd is taken hostage by her and his ghost collection, which includes King Boo, is plundered before he becomes trapped in a painting. He is later saved by Luigi, who escaped a similar trap and borrowed the [[Poltergust G-00]] from E. Gadd's car in the hotel's basement. E. Gadd initially attempts to flee the hotel, but when Luigi insists on staying to save his captured friends, E. Gadd relents. After setting up [[Lab (Luigi's Mansion 3)|his portable lab]] in the basement, E. Gadd gives Luigi the [[Virtual Boo]] for communication purposes. He later has [[Gooigi]] accompany Luigi throughout the hotel. He also uses the lab to provide a safe haven for the saved Toads.
 
Towards the end of the game, King Boo attacks Professor E. Gadd's lab when Luigi follows after the recently-released Mario to find Princess Peach, and traps him and everyone else in a single painting. Luigi is saved from the painting by Polterpup, and he manages to recapture King Boo and free all his friends. E. Gadd also offers to help the ghosts rebuild the now destroyed Last Resort complex (which was apparently his idea), providing construction hard-hats to Luigi and some of the ghosts (although a [[Hammer (Luigi's Mansion 3)|Hammer]] obliviously eats his). After the hotel is rebuilt in E. Gadd's likeness, Professor E. Gadd stays behind with Gooigi and the ghosts while everyone else departs.
 
While E. Gadd is following Luigi, one of the poses he strikes if flashed by the Strobulb references {{wp|Marilyn Monroe}}'s famous "white dress scene" in ''{{wp|The Seven Year Itch}}''. The back of his lab coat even flutters upward during the pose.

====''Super Mario Sunshine''====
Although Professor E. Gadd does not appear in ''[[Super Mario Sunshine]]'', when Mario initially finds [[F.L.U.D.D.|FLUDD]] at the [[Delfino Airstrip]], it says, ''"Thank you for purchasing this item from Gadd Science, Inc."'' Later, [[Bowser Jr.]] says he got his [[magic brush]] from "a strange old man in a white coat." Bowser Jr. uses the paintbrush to frame Mario and get him away long enough for himself to go in and kidnap Princess Peach. This is a fitting description of Professor E. Gadd, which is further confirmed when FLUDD seems to react in surprise to the statement. Bowser Jr. claims E. Gadd gave the brush to him of his own free will and that he did not know the professor's name when he received the brush, but it is unknown whether this is true or not. There is a symbol on both the magic brush and FLUDD showing a face and hairstyle similar to E. Gadd's, which seems to be the Gadd Science, Inc., logo. It appears on many of E. Gadd's other inventions, as well as [[nozzle box]]es.
 
====''Super Mario Maker''====
E. Gadd makes an appearance in ''[[Super Mario Maker]]'' as a [[Mystery Mushroom]] [[Costume Mario|costume]] for Mario when using the ''Super Mario Bros.'' theme. The costume can be unlocked by completing the [[Event Course]] [[Paranormal Research]].

In ''[[Mario & Luigi: Superstar Saga]]'', E. Gadd owns [[Starbeans Cafe]] in [[Beanbean Castle Town]]. If Mario and Luigi brew a new coffee blend, E. Gadd arrives and requests a drink. They offer E. Gadd the drink, and he rewards them with equippable [[Starbeans Cafe#Special Items|Special Items]] that grant special effects. [[List of Mario & Luigi: Superstar Saga pre-release and unused content|Originally]], the game was going to feature Professor E. Gadd only once, only when Mario and Luigi brewed the [[Woohoo Blend]]; for other drinks, different characters would have appeared. These characters were [[Wario]], [[Samus|Samus Aran]], [[Fox|Fox McCloud]], [[Link]], an ''Excitebike'' racer, and [[Captain Olimar]].
In ''[[Mario & Luigi: Superstar Saga]]'', the professor makes an appearance supplying the brothers with an array of accessories to help them along their way each time they drink at [[Starbeans Cafe]], a juice shop that he owns. However, it has been found that originally, the game was only going to feature Professor E. Gadd once, the first time Mario and Luigi get a drink; in all of the future times, different characters would have appeared. These characters are [[Wario]], [[Samus Aran]], [[Fox McCloud]], [[Link]], an ''Excitebike'' racer, and [[Captain Olimar]].
 
{{br|right}}
While Professor E. Gadd reprises his role in the remake of ''Mario & Luigi: Superstar Saga'', ''[[Mario & Luigi: Superstar Saga + Bowser's Minions]]'', he also shows up during the ''Minion Quest: The Search for Bowser'' side story. Here, he is found in a cave by Bowser's minions, claiming to have followed ghosts when he fell in. E. Gadd begins talking to Bowser's minions about his research, and says he is also working on a time-travel device, a nod to [[Mario & Luigi: Partners in Time|the original main story's sequel]]. He also alludes to Starbeans Cafe and reveals he founded the company as a way to get funding into his ghost research.
 
;Reactions to the drinks
The professor has many different reactions for each time a new drink is made at Starbeans Cafe, usually accompanied with a humorous scene.
*The first reaction gives a reference to ''[[Luigi's Mansion]]'' when the new brew attracts a [[Gold Ghost]], which scares Luigi, but the professor comes in with the [[Poltergust 3000]] and sucks it up. The professor explains that he owns the Cafe, and that each time he samples a new brew, he will give a gift to the Bros. He samples the brew and gifts to them the [[Greed Wallet]].
*The second reaction has the professor drawn in by the smell of the drink, and samples a flavor. He then gives the Bros. the [[Bonus Ring]]. The professor then has a major reaction to the very "Strong Brew" and asks the bartender where the bathroom is. The bartender replies that he had never built one. Luigi then rushes to get the Poltergust 3000 and sucks the professor in.
*The third reaction has him on a Poltergust 3001, a rocket. He samples the drink and gives the [[Excite Spring]] before blasting away.
*The fourth has him on a giant Game Boy Horror. He sends a [[Speedy Spirit]] as a representative for the sampling, much to Luigi's terror. After that, the ghost drops the [[Great Force]].
*In the fifth reaction, he has the giant Game Boy Horror send the drink to him. He then gifts them the [[Power Grip]] in the original or [[Secret Specs]] in the remake. He promises to come in person the next time a new brew is made.
*In the sixth reaction, E. Gadd comes wearing a suit that makes him a ghost. He samples the drink and gives the [[Cobalt Necktie]]. A terrified Luigi uses the Poltergust 3000 to suck the professor inside.
*In the final one, he samples the last drink and proclaims it the best one, much to his employee's annoyance. He gives the Bros. the [[Game Boy Horror SP]]. Before leaving, he hangs a photo of himself in the shop as a way to brighten one's spirits, which the employee labels dumb.

Out in the courtyard, Mario and Luigi discover a hole in the ground; E. Gadd elaborates that this hole is a [[time hole]], a rip in the time-space continuum, which was created by the use of the time machine. After Luigi falls in the hole and Mario heads in to save him, the professor sends [[Stuffwell]], a sentient suitcase, through to help them. For most of the game, E. Gadd is seen studying the Junior Shrooboid defeated earlier. He is able to communicate with Stuffwell even if the brothers and Stuffwell travel to the past.

At [[Thwomp Volcano]], Mario, Luigi, and their baby counterparts come across and paradoxically meet a [[Elvin Gadd (past)|younger Professor Gadd]], who is studying [[Thwomp]]s. During this time, though, the volcano erupts, with several Thwomps falling in and destroying the laboratory. One threatens to explode, and must be put out; Baby Mario and Baby Luigi do this by having Baby Mario drink water and Baby Luigi hammering him to spit it at the Thwomp, dousing it. Witnessing this event in the past causes the present day E. Gadd's memories to be rearranged and inspires him to invent the [[Hydrogush 4000]], a massive water pump. Mario and Luigi then have him pump water through the time hole leading to Thwomp Volcano to douse the mountain. After his lab is destroyed by the eruption of the volcano, young E. Gadd mentions his interests in studying ghosts, and that he would be buying a lab at the edge of Boo Woods, nodding toward his first appearance in ''Luigi's Mansion''.

After discovering that baby tears are the [[Shroob]]'s weakness, Mario, Luigi, and Princess Peach relate this to the professor. E. Gadd then uses the Hydrogush to pump a liquid similar to Baby Luigi's tears through the time holes, removing the Shroobs and restoring any Shroobified characters. He also restores the time machine and uses it to bring everyone back to the future.

Gadd is referred to by his full name - Professor Elvin Gadd - in North America, while PAL regions have his first name abbreviated.


E. Gadd appears in ''[[Super Smash Bros. for Nintendo 3DS]]'' as a collectible trophy. The description of his trophy talks about his role within ''Luigi's Mansion: Dark Moon'', describing the events of the Dark Moon being shattered, and the professor calling upon Luigi to aid him. E. Gadd is referred to by his full name - Professor Elvin Gadd - in American English, while the British English version has his first name abbreviated.
Despite not appearing in any ''[[Super Smash Bros. (series)|Super Smash Bros.]]'' titles until the fourth installment, E. Gadd is mentioned in the trophies for F.L.U.D.D. and the Poltergust 3000 in ''[[Super Smash Bros. Brawl]]'', the trophy representing the various Ghosts that appeared in ''Dark Moon'' in ''Super Smash Bros. for Nintendo 3DS'', as well as Luigi's [[Final Smash|final smash]] trophy, the Poltergust 5000, in ''[[Super Smash Bros. for Wii U]]''.


Additionally, E. Gadd appears as a [[Spirit (Super Smash Bros. Ultimate)|spirit]] in ''[[Super Smash Bros. Ultimate]]'', as well as "EGADD" being one of the randomly generated names the player can receive.
===''Super Mario Maker''===
E. Gadd also makes an appearance in ''[[Super Mario Maker]]'' as a [[Mystery Mushroom]] [[Costume Mario|costume]] for Mario when using the ''Super Mario Bros.'' theme. The costume can be unlocked by completing the [[Event Course]] [[Paranormal Research]].

===Unused appearances===
;[[DS Time Radar]]
====''Mario Kart DS''====
A handheld device that bears a striking resemblance to a [[Nintendo DS]] used briefly by E. Gadd to find [[Princess Peach]] in ''Mario & Luigi: Partners in Time''. It has the ability to pinpoint which time period someone is trapped in. One of the [[Toad (species)|Toads]] thinks he just made it up. Also, when Professor E. Gadd turns on his Hydrogush 4000, he uses a DS-like device.
There is evidence in the [[List of Mario Kart DS pre-release and unused content#Characters|US demo prototype version]] of ''[[Mario Kart DS]]'' that E. Gadd was going to be playable, which would have been his first playable appearance, but he was replaced with [[Dry Bones]] in the final version.
 
;[[Dual Scream]]
An upgraded DS given to Luigi in ''[[Luigi's Mansion: Dark Moon]]'', that acts both as a communication device, and as a map of the area.
 
;E. Gadd Battle Machine
Special parts that can be bought in the Super Duel Mode of ''[[Mario Party 5]]''. They include the E. Gadd body, E. Gadd Jet, E. Gadd Engine and E. Gadd gun.

;[[F.L.U.D.D.]]
[[File:FLUDD.jpg|thumb|right|F.L.U.D.D., from ''Super Mario Sunshine''.]]
The Flash Liquidizer Ultra Dousing Device, better known as F.L.U.D.D., is a water-spraying device used by Mario in ''Super Mario Sunshine''. It is worn on Mario's back, and has various nozzle attachments which can be collected by breaking open boxes with E. Gadd's logo on the front. F.L.U.D.D. also has notable artificial intelligence and the ability to communicate with a voice. In certain ways, F.L.U.D.D. functions much as Navi did in ''The Legend of Zelda: Ocarina of Time''.
 
;[[Gaddget]]s
The Gaddgets appeared in ''[[Mario Party Advance]]''. There were 80 total, and were very similar to the toys in the ''[[WarioWare, Inc.|WarioWare]]'' games.
 
;[[Gaddlight]]
A flashlight that is used to scare away [[Boo]]s when they try to steal a Star or [[coin]]s in ''[[Mario Party 4]]''.
 
;[[Game Boy Horror]]
[[File:MLSS-Game Boy Horror SP Sprite.png|frame|left]]
The Game Boy Horror is a portable device from ''Luigi's Mansion'' that bears a striking resemblance to the [[Game Boy Color]] containing a built-in camera which E. Gadd can use to watch the action from the safety of his lab and contact Luigi. It also stores data including a map and anything Luigi has collected, and contains a special radar called the Boo Radar to find hidden spherical objects.
{{br|left}}
 
;[[Game Boy Horror SP]]
The Game Boy Horror SP is an upgraded version of the Game Boy Horror, given to Mario by E. Gadd in ''Mario & Luigi: Superstar Saga''. It is another portable device, this time bearing a striking resemblance to a [[Game Boy Advance SP]]. It always gives the Bros. access to rare items in battle.
 
;Ghost Container
A machine that holds the ghosts captured throughout [[Evershade Valley]] and the [[ScareScraper]] in [[Luigi's Mansion: Dark Moon]]. It also provides research information on all captured ghosts including their spectral mass (weight).
 
;[[Ghost Gown]]
A pale blue jacket that, when worn, turns characters into a ghost. When E. Gadd wore this in ''[[Mario & Luigi: Superstar Saga]]'', Luigi got scared and used the Poltergust 3000 to vacuum him up.
 
;[[Ghost Portrificationizer]]
The Ghost Portrificationizer is a large machine which works in conjunction with the Poltergust 3000. Certain ghosts captured can be entrapped in portraits to be hung in E. Gadd's gallery. The machine also works in reverse, which was utilized to free Mario from the painting he had been trapped in by [[King Boo]]. E. Gadd also commented that it took him twenty years to build.
 
;[[E. Gadd's Vault]]
A vault E. Gadd made to contain the ghosts of [[Evershade Valley]] and the [[ScareScraper]] in [[Luigi's Mansion: Dark Moon]]. It holds the Boo and Ghost Containers, a machine where Gemstones and their statues are stored, as well as a device which displays Poltergust 5000 upgrades, and a Bank Vault where treasure that is collected throughout the game is stored and tallied. 
 
;[[Hydrogush 4000]]
A large water pump used in ''Mario & Luigi: Partners in Time''. It's not portable like the F.L.U.D.D., but it does have a lot of power.
 
;[[Magic Orb]]
A magic wand in ''[[Mario Party 7]]'', which has the E. Gadd logo on it. It is exclusive to [[Boo]] and [[Dry Bones]]. It was used to turn the characters invisible, making them impervious to traps, and to double their rolls on [[Dice Block]]s for two turns.
 
;[[Magic Paintbrush]]
[[File:Bowser Jr. Artwork - Super Mario Sunshine.png|left|thumb|Bowser Jr. holding the Magic Paintbrush.]]
The Magic Paintbrush is used by Bowser Jr. (as [[Shadow Mario]]) in ''Super Mario Sunshine''.) It is a large paint brush with the ability to paint various colors, though this magic paint can change the landscape, create portals, and create obstacles or enemies. It is unclear why E. Gadd made the brush, as well as why it was given to Bowser Jr., though the latter may be due to Bowser Jr. being disguised as [[Mario]]. In ''[[Mario Power Tennis]]'', ''[[Mario Hoops 3-on-3]]'', ''[[Mario Super Sluggers]]'', ''[[Mario Sports Mix]]'', and ''[[Super Smash Bros. for Nintendo 3DS / Wii U]]'', Bowser Jr. uses his Magic Paintbrush to perform special moves.
 
;Maze Manufactory
A maze-making machine from the ''[[Mario Party 6]]'' minigame [[Lab Brats]].

===Appearance===
[[File:Egadd.png|thumb|200px|left|Professor E. Gadd in ''Luigi's Mansion'']]
Professor E. Gadd is a small, elderly man. He wears brown shoes and a white lab coat with a red shirt underneath. He has a large head wider than his body, with a pink nose, a mouth with a singular tooth, large glasses with circles in them, and a tall but thin amount of white hair on his head. He has small dotted eyes, which are normally obscured by his glasses, but can be seen in some games if viewed at certain angles.<ref>{{cite|author=Shesez|date=July 14, 2019|url=youtu.be/7E-9moqWXRk?t=133|title=Top 10 Hidden Faces in Video Games... Revealed!|timestamp=02:13|publisher=YouTube|accessdate=November 3, 2019}}</ref> Glasses with swirls that are often seen in Japanese media are a feature E. Gadd shares with [[Mad Scienstein]], [[Professor Frankly]], [[Fawful]], [[Francis]], and [[Iggy|Iggy Koopa]]. In ''[[zeldawiki:The Legend of Zelda: The Wind Waker|The Legend of Zelda: The Wind Waker]]'', there is a character named [[zeldawiki:Mako|Mako]] whose face resembles E. Gadd's.


In ''Mario & Luigi: Superstar Saga'' and its remake, he can also wear a large blue coat.
;[[Pixelator]]
{{stub|section=yes}}
E. Gadd uses the Pixelator to send Luigi, and his Toad assistants, from the various mansions in ''[[Luigi's Mansion: Dark Moon]]''.
{{br}}
;[[Poltergust 3000]]
[[File:BrawlTrophy186.png|thumb|200px|right|The Poltergust 3000.]]
The Poltergust 3000 is a modified vacuum cleaner designed to entrap ghosts. It also has a "blow" function which allows it to expel elements it sucks up such as fire, water, and ice. Luigi uses this in ''Luigi's Mansion'' to defend himself from the many ghosts; it also makes a return in ''[[Mario Power Tennis]]'' where Luigi uses it as his defensive [[Power Shot]], using its suction power to retrieve the ball. It also appeared in a [[Trophy (Super Smash Bros. series)|trophy]] in ''[[Super Smash Bros. Melee]]'' and ''[[Super Smash Bros. Brawl]]''. The Poltergust 3000 is also used by [[Luigi]] in [[Mario Sports Mix]] for his special ability.


===Inventions===

[[File:Poltergust 3001.PNG|thumb|left|E. Gadd on the Super Poltergust 3001.]]
{{image|more=yes|Needs an image of the full E. Gadd Battle Machine}}
The Super Poltergust 3001 is an advanced version of a Poltergust 3000. It has the same functions as the Poltergust 3000, but is much larger thereby allowing it to be ridden on. When ridden, it hovers over the ground. It is capable of moving at high speeds. E. Gadd briefly demonstrates the invention and uses it in ''Mario & Luigi: Superstar Saga''.

;[[Poltergust 4000]]
===''Mario & Luigi: Partners in Time''===
[[File:Luigi (alt 2) - Mario Kart DS.png|thumb|[[Luigi]] in the Poltergust 4000.]]
*'''Guide bio:''' "''The Mushroom Kingdom's resident mad scientist, Professor E. Gadd, is responsible for creating the time machine. The professor will aid Mario and Luigi by offering advice and guiding the brothers to their next objective. He talks like an Ewok.''"<ref>{{cite|author=Hoffman, Chris|title=''Mario & Luigi: Partners in Time Nintendo Player's Guide''|page=3|date=November 18, 2005|publisher=Nintendo of America|language=en-us|isbn=1598120069}}</ref>
The Poltergust 4000 is one of the vehicles used by Luigi in ''[[Mario Kart DS]]'' to race in. It is similar to the Super Poltergust 3001, though it does not float. The "barrel" of the car is the area Luigi sits on, and the nozzle rests on the ground. Emblems are placed on both sides of the barrel.


===''Luigi's Mansion'' series===
;[[Poltergust 5000]]
====''Luigi's Mansion: Dark Moon''====
A vacuum that Professor E. Gadd creates for Luigi to vacuum up more ghosts in ''[[Luigi's Mansion: Dark Moon]]''. It is a successor to the Poltergust 3000 and it creates a large circular sucking motion rather than the small sucking motion from the first game, making it a lot easier to defeat multiple ghosts at once. There are also different accessories designed for the Poltergust 5000, such as the [[Strobulb]] and the [[Dark-Light Device]].
*'''North American website bio:''' "''Known for his paranormal research and plethora of wild inventions, Professor E. Gadd just needs someone crazy enough to put them to the test.''"<br>
*'''European website bio:''' "''An eccentric scientist who invented the Poltergust 5000, a big improvement on the previous 3000 model. After the ghosts turn hostile and take over mansions, he calls on his old friend Luigi to help out.''"


====''Luigi's Mansion 3''====
;[[Robo Mario]]
*'''In-game bio:''' "''A genius inventor and the leading authority in the field of ghost research. His beloved ghost collection is said to be the best in all the world! He supports Luigi in his adventures...from the safety of his Lab, that is!''"
This robotic entity of Mario races against players in the Rainbow Cup challenge game in ''[[Mario Kart Arcade GP 2]]''. It spawns an infinite number of items and changes items depending on its place.


===''Super Smash Bros.'' series===
;[[Starbeans Cafe]]
====''Super Smash Bros. for Nintendo 3DS''====
The beverage shop in the Beanbean Kingdom, founded and owned by E. Gadd. Every time Mario and Luigi mix a new drink, E. Gadd visits. This continues until E. Gadd stops visiting and puts up a larger-than-life-size portrait of himself.

====''Super Smash Bros. Ultimate'' spirit====
;[[Stuffwell]]
{{spirit
An intelligent suitcase used by the Mario Bros. on their quest in ''Mario & Luigi: Partners in Time''. Its purpose is to manage the brothers' inventory and display their current status. It also helps the brothers by activating the [[Shroob]] Saucers that are used in the game, and eventually near the end develops the ability to return to the past before rescuing Princess Peach. It is known to use large and overly complex made-up words when he speaks, and upon ending its speeches, says "BACK TO ADVENTURE!"

*In ''[[The Super Mario Bros. Super Show!]]'' episode "[[Robo Koopa]]", there is a scientist named [[Dr. Nerdnick]] who bears a passing resemblance to E. Gadd due to their similar appearance and the fact that they both speak in incomprehensible gibberish.
*Professor E. Gadd is one of the few characters in the franchise who existed prior to [[Nintendo]]'s translating games and websites to Dutch to receive a new name in said translation, as opposed to keeping his English name.
*In ''[[Super Smash Bros. Brawl]]'', one of the names that can appear when a player presses the random button in naming their custom stage is "EGADD".
*Glasses with swirls are often seen in Japanese media<ref>[http://themushroomkingdom.net/mariosan.shtml The Mushroom Kingdom] (Accessed on 6-12-09)</ref> that are a feature E. Gadd shares with [[Professor Frankly]], [[Fawful]], [[Francis]], and [[Iggy Koopa]].
