'''Prankster Comets''' are special missions that appear in ''[[Super Mario Galaxy]]'' and ''[[Super Mario Galaxy 2]]''. They affect [[Galaxy|galaxies]] by changing the gameplay of the level. Prankster Comets resemble fireballs with tails, like real comets, hence their name.

In ''Super Mario Galaxy'', there are five different types of Prankster Comets, each one a different color: red, white, blue, yellow, or purple. They appear occasionally in the orbits of the 15 major galaxies, starting at the point when [[Mario]] or [[Luigi]] collects his thirteenth [[Power Star]]. The missions can be done only if the player travels to a galaxy with a Prankster Comet in orbit. Prankster Comets appear in galaxies only after a specific Power Star in any given galaxy is collected. Also, when a Prankster Comet is in orbit, the player is forced to choose the Prankster Comet's level. No option is given to choose "normal" levels until the Prankster Comet's completion. However, [[Comet Luma]]{{derived}}, who is positioned near the [[Terrace (Super Mario Galaxy)|Terrace]], can shuffle the comets between available galaxies if fed 20 [[Star Bit]]s by the player. Comet Luma's actions either remove all the comets from orbiting in galaxies, remove some of them, or make some appear.

By completing the event, the player receives a Power Star. While a Prankster Comet is in orbit of a galaxy, players need to completely restart the level each time they lose a life, instead of coming back at the last [[checkpoint]]. Once a Prankster Comet's Star has been collected, its Star becomes a selectable mission, only causing the comet to return to the corresponding galaxy at the player's request. All the Prankster Comets (except Purple Comets without time limits) also have their own music that plays during their missions. Prankster Comets give their levels a haze whose color depends on what effects they have.

In ''Super Mario Galaxy 2'', Prankster Comets appear only once the player has collected a [[Comet Medal]] in a certain galaxy, as well as a certain number of Comet Medals from other galaxies (and collected at least four Power Stars from World 3), and their levels have a black haze, regardless of the effect. In this game, Prankster Comets with different effects are no longer considered different types of comets. Galaxies under the influence of a Prankster Comet are given a generic symbol. Below, the ''Super Mario Galaxy 2'' comets are grouped together based on the title of the mission they appear in. Comets are now yellow if they give regular Power Stars, while comets are green if they give [[Green Star]]s. Traveling to a galaxy with a comet in orbit opens the comet Star mission, although the player may have the option to select a normal mission, unlike in the first game. Also, a Prankster Comet is always in orbit around a galaxy once unlocked, unlike in the first game, where completing a mission can move the Prankster Comet to another galaxy. Certain galaxies such as the [[Fluffy Bluff Galaxy]] and [[Boo Moon Galaxy]] do not have Prankster Comets.

A '''Speedy Comet''' requires the player to complete a level within a certain time limit, from four to six minutes; failing to do so results in the player losing a life. Also, there are small changes in the galaxies. For example, the [[Good Egg Galaxy]]'s [[boulder|Ruby Rock]]s are all replaced by [[Chain Chomp|Chomp]]s. Speedy Comets are red, and their respective levels have a red haze that becomes more pronounced at the edges of the screen. Four galaxies are visited by Speedy Comets: the Good Egg Galaxy, [[Space Junk Galaxy]], [[Dusty Dune Galaxy]], and [[Dreadnought Galaxy]].

Speedy Comets also appear in ''Super Mario Galaxy 2''. A list of galaxies visited by Speedy Comets includes the [[Sky Station Galaxy]], [[Bowser Jr.'s Fiery Flotilla]], [[Hightail Falls Galaxy]], [[Bowser's Lava Lair]], [[Rolling Masterpiece Galaxy]], [[Supermassive Galaxy]], [[Bowser's Gravity Gauntlet]], [[Throwback Galaxy]], [[Bowser's Galaxy Generator]], the [[Stone Cyclone Galaxy]], and the [[Boss Blitz Galaxy]]. Unlike in the previous game, a Speedy Comet in ''Super Mario Galaxy 2'' can dramatically change the original level in addition to setting a time limit. For example, [[Hightail Falls Speed Run]] has damaged platforms and [[meteor]]s, and [[Masterpiece Speed Run]] has an entirely new planet not seen in the original Star mission as part of the level. Unlike in the first game, the timer disappears once the Power Star appears. The haze is also changed to black, akin to the Daredevil Comet.

A '''Daredevil Comet''' cuts Mario or Luigi's maximum health down to only one hit point, as opposed to the usual three (or six with a [[Life Mushroom]]). Additionally, it removes all Life Mushrooms and coins from the level so that the player cannot gain more health or exploit a [[glitch]] to take damage without losing a life, and coins do not spawn from [[stomp]]ing enemies. Daredevil Comets themselves are white, though their icons are light grey and the haze in their respective levels is black. Five galaxies are visited by Daredevil Comets: [[Battlerock Galaxy]], [[Ghostly Galaxy]], [[Gusty Garden Galaxy]], [[Deep Dark Galaxy]], and [[Melty Molten Galaxy]]. The former four have the player battle a previously fought boss ([[Topmaniac]], [[Bouldergeist]], [[Major Burrows]], and [[Kamella]], respectively), while Melty Molten Galaxy has the player complete the entire first mission ([[The Sinking Lava Spire]]) with only one hit point. Taking any damage during a Daredevil Comet requires the player to start the mission over from the beginning. At the start of the first four aforementioned galaxies, the player is automatically brought to the last planet where the boss resides, without the need to travel throughout the galaxy.  

Daredevil Comets are also in ''Super Mario Galaxy 2'' in [[Spin-Dig Galaxy]], [[Bowser Jr.'s Fearsome Fleet]], the [[Slipsand Galaxy]], [[Bowser Jr.'s Boom Bunker]], the [[Battle Belt Galaxy]], and the [[Grandmaster Galaxy]]. Unlike in the first game, however, some of the daredevil runs in ''Super Mario Galaxy 2'' have [[Checkpoint Flag]]s. Just like with a Speedy Comet, the original level can be dramatically changed when visited by a Daredevil Comet. For instance, one planet is replaced by another one in Bowser Jr.'s Boom Bunker.

A '''Cosmic Comet''' pits Mario in a race against [[Cosmic Mario]] in a predetermined course with a [[Power Star]] at the end. Mario must beat his duplicate to the Star; if he fails, he loses a life. Cosmic Comets are blue, as is the haze in their respective levels. Four galaxies are visited by Cosmic Comets: the [[Honeyhive Galaxy]], [[Freezeflame Galaxy]], [[Gold Leaf Galaxy]], and [[Sea Slide Galaxy]]. If the player uses [[Luigi]], they race against Cosmic Luigi instead. Unlike Cosmic Mario, Cosmic Luigi [[Long Jump|long-jump]]s frequently and takes advantage of some shortcuts that are available. Cosmic Comets appear only in ''Super Mario Galaxy''; they are replaced by [[#Clone Comet|Clone Comets]] in ''Super Mario Galaxy 2''.

A '''Fast-Foe Comet''' speeds up all enemies and obstacles in a stage. Mario must complete the stage while avoiding the accelerated enemies and obstacles. Fast-Foe Comets are yellow in color, though their icon and the haze in their respective level are of a golden hue. Only two galaxies are visited by Fast-Foe Comets: the [[Beach Bowl Galaxy]] and [[Toy Time Galaxy]]. [[Tox Box]]es, [[Thwomp]]s, and moving platforms are the only objects affected. Fast-Foe Comets appear only in ''Super Mario Galaxy''; they are replaced by [[Prankster Comet#Double Time Comet|Double Time Comets]] in ''Super Mario Galaxy 2''.

A '''Purple Comet''' is available only after the player clears [[Bowser's Galaxy Reactor]]. When they strike a galaxy, Purple Comets scatter [[Purple Coin]]s throughout the galaxy or a specific region of it, and Mario must retrieve at least 100 Purple Coins, sometimes within a time limit, to retrieve the Star. Some Purple Comet missions have more than 100 Purple Coins, but Mario still needs to collect only 100 for the Star. Purple Comets give their levels a purple haze. All 15 major galaxies are visited by Purple Comets. Timed Purple Comet missions, as well as the [[Battlerock Galaxy]]'s and [[Dreadnought Galaxy]]'s Purple Comet missions, use a unique background music track, which is an arrangement of the [[Gusty Garden Galaxy (theme)|Gusty Garden Galaxy music]].

There are also Purple Comets in ''[[Super Mario Galaxy 2]]''. They are the same as in ''Super Mario Galaxy'', but their levels gain a black haze, and instead of having to beat the game for Purple Comets to come, only the galaxy's [[Comet Medal]] is required. The mission in [[Starshine Beach Galaxy]] plays the [[Hightail Falls Galaxy]] music, since the [[Dash Pepper]] is needed to clear, even though the normal level has a Dash Pepper and using it does not change the music. The specific Purple Coin theme from the first game plays in the Flip-Swap Galaxy, Puzzle Plank Galaxy, Clockwork Ruins Galaxy, and Mario Squared Galaxy. Unlike in the first game, during the Purple Coin missions with time limits, the timer disappears once the required number of Purple Coins is collected.

|2:00<br>If Mario has fewer than 100 [[Purple Coin]]s,<br> he loses a life.

A '''Clone Comet'''{{ref needed}} replaces the Cosmic Comet from the first game. Multiple [[Cosmic Clone]]s appear in a selected mission. The player needs to redo the whole or part of the mission while there are Cosmic Clones. Clone Comets appear in the [[Cloudy Court Galaxy]], the [[Haunty Halls Galaxy]], the [[Chompworks Galaxy]], and the [[Flip-Out Galaxy]]. The comets are fused with the missions [[Purple Coin Shadow Vault]] for [[Puzzle Plank Galaxy]], [[Luigi's Purple Coin Chaos]] for [[Mario Squared Galaxy]], and [[Flip-Out Galaxy#Green Star2|Green Star 2]] for [[Flip-Out Galaxy]]. The specific music for the Cosmic Clones theme does not play (except in the Cloudy Court Galaxy), even though the soundtrack stays the same. This music is also played in other stages such as [[Stone Cyclone Galaxy]]. Clone Comets appear only in ''Super Mario Galaxy 2'', and their levels have a black haze, just like all the other Prankster Comets.

A '''Romp Comet'''{{ref needed}} requires Mario to defeat a horde of 30 enemies within a time limit by using a power-up, with the exception of the Flash Black Galaxy, where no power-up is given. Romp Comets appear in the [[Yoshi Star Galaxy]], the [[Boulder Bowl Galaxy]], the [[Flash Black Galaxy]], and the [[Shiverburn Galaxy]], and their missions often feature a fast-paced theme, such as the minigame theme. The comets appear only in ''Super Mario Galaxy 2''.

A '''Double Time Comet'''{{ref needed}} makes the player redo a level, this time with the hazards moving faster. Double Time Comets appear in [[Beat Block Galaxy]] and [[Twisty Trials Galaxy]]. Their effect is similar to that of the Fast-Foe Comets from the first game, except that instead of enemies, the stage hazards move faster, and slightly slower overall than when a Fast-Foe Comet is in orbit. Despite the comet being called the "Double Time Comet," the objects actually move at four times the normal speed. Double Time Comets appear only in ''Super Mario Galaxy 2''.

A '''Green Comet''' makes [[Green Star]]s appear in various levels in every galaxy except the [[Grandmaster Galaxy]], usually in hidden or hard-to-reach places. There is one Green Star for every normal Power Star mission; galaxies with two missions have two Green Stars to find, and galaxies with three missions have three Green Stars to locate. In either case, Green Star levels are always named "Green Star 1" and "Green Star 2" (as well as "Green Star 3" for galaxies with six Power Stars total) as opposed to being named the same way as normal galaxy levels. Green Comets appear only in ''Super Mario Galaxy 2''. Unlike most Prankster Comets, Green Stars do not give their respective levels a haze.
