'''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."

[[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 the [[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. Gadd|title=''[[Luigi's Mansion]]''|date=2001}}</ref> In order to get funding for his ghost research, E.

[[File:Professor Elvin Gadd.jpg|thumb|Professor E. Gadd with the original design for the Poltergust 3000 in ''Luigi's Mansion''.]]

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.

====''Luigi's Mansion: Dark Moon'' / ''Luigi's Mansion 2 HD''====

[[File:LMDM EGadd Luigi.png|thumb|left|E. Gadd with [[Luigi]] in ''Luigi's Mansion: Dark Moon''.]]

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 [[Lab|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.

====''Luigi's Mansion Arcade''====

E. Gadd has a similar role in ''[[Luigi's Mansion Arcade]]'' to that of ''Luigi's Mansion: Dark Moon'', in that he communicates with Luigi while the latter explores the mansions, and offers a tutorial to the player upon starting the game.

[[File:E Gadd with Poltergust LM3 art.png|thumb|Professor E. Gadd in ''Luigi's Mansion 3'' with the [[Poltergust G-00]]]]

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 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.

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.

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]].

[[File:MLSS-E Gadd Ghost.png|frame|Professor E. Gadd sucking up a ghost in ''[[Mario & Luigi: Superstar Saga]]''.]]

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]].

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.

*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 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.

[[File:Professor Elvin Gadd PiT.png|left|thumb|200px|Professor E. Gadd appearing in ''Mario & Luigi: Partners in Time''.]]

E. Gadd has a much larger role in ''[[Mario & Luigi: Partners in Time]]'', he introduces his newest invention to the [[Mushroom Kingdom]], a [[Prof. E. Gadd's time machine|time machine]] in [[Peach's Castle]]. [[Princess Peach]], accompanied by [[Toadiko]] and [[Toadbert]], volunteers to travel in the machine. However, when the time machine returns, the [[Junior Shrooboid]] emerges from it. After the bros. defeat it, Gadd keeps it submerged in a tank, allowing him to study it.

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 the 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.

===''Mario Party'' series===

A flashlight known as the [[Gaddlight]] was used to scare away [[Boo]]s when they try to steal a [[Power Star|Star]] or [[coin]]s in ''[[Mario Party 4]]''.  

In ''[[Mario Party 5]]'''s [[Super Duel]] mode, several vehicle parts are designed by E. Gadd.

[[E. Gadd's Garage|Professor E. Gadd's garage]] is a game board in ''[[Mario Party 6]]''. When a player lands on a [[Event Space|? space]] on this board, E. Gadd appears and lets them try one of his inventions.

[[File:MPA ProfessorElvinGadd.jpg|thumb|Professor E. Gadd as seen in ''Mario Party Advance''.]]

In ''[[Mario Party Advance]]'', E. Gadd appears as the co-host of Play Land. The coins earned in the minigames can be used to buy Professor E. Gadd's many "Gaddgets".  

A [[Magic Orb|magic wand]] and a [[Vacuum Orb]] bearing Gadd's logo are featured in ''[[Mario Party 7]]''.

E. Gadd makes a small cameo in ''[[Mario Kart Arcade GP]]'' as a statue in the background of the [[Diamond City (arcade)|Diamond City]] course in the Wario Cup. His face, the logo of Gadd Science, appears on a building as well. This cameo carries over into the sequel, ''[[Mario Kart Arcade GP 2]]''. It is implied that E. Gadd is the creator of [[Robo Mario]], as evidenced by the logo on Robo Mario's cap.

In ''[[Super Smash Bros. Brawl]]'', one of the names that can appear when a player presses the random button when naming their custom stage is "EGADD".

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.

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.

Despite not appearing in any ''[[Super Smash Bros. (series)|Super Smash Bros.]]'' titles until the fourth installment, E. Gadd is mentioned in the Vacuum Luigi trophy in ''[[Super Smash Bros. Melee]]'', the trophies for [[F.L.U.D.D.]] and the [[Poltergust 3000]] in ''[[Super Smash Bros. Brawl]]'', the trophy representing the various [[ghost (Luigi's Mansion series)|ghosts]] that appeared in ''Dark Moon'' in ''Super Smash Bros. for Nintendo 3DS'', and Luigi's [[Final Smash]] trophy, the [[Poltergust 5000]], in ''[[Super Smash Bros. for Wii U]]''.

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.

[[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...

In ''Mario & Luigi: Superstar Saga'' and its remake, he can also wear a large blue coat.

*One of E. Gadd's voice lines, "Oyamaa", is both his Japanese name and an exclamation of surprise. This happens even in overseas releases. He can also sometimes be heard saying "Luigi!" or "Mario!"

*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.
