Luigi's Mansion Wiki

Allow me to introduce this green doppelgänger. I call him Gooigi!
—Professor Elvin Gadd


Gooigi is a green doppelgänger of Luigi, created by E. Gadd during the events of Professor E. Gadd's Research Journal with a new intelligent chemical element discovered by the professor called Goo.

The character is introduced for the first time as the second player in Luigi's Mansion (3DS) and later he reappears in Luigi's Mansion 3, this time having a much bigger role in the mechanics and story.

Information[]

Physical description[]

Gooigi has the exact same appearance as Luigi but with a translucent green effect in all his body, caused by the material he is created with, the Goo. He also has a letter "G" on his hat instead of an "L", although in some polaroids shown in Professor E. Gadd's Research Journal he's shown without any kind of letter in his hat, leaving an empty space in the front of it.

Contrary to Luigi, he'll always be seen with the same serious and emotionless expression, no matter the situation.

The Poltergust that he is wearing is part of him, and this one can be changed and used by him like any of the existing Poltergust models created by the professor depending in the game he is in.

Personality[]

Gooigi appears to be devoid of much personality and emotions, not freaking out or getting surprised by ghosts or dangerous situations around him, instead often acting unresponsive, contrary to Luigi. This lack of empathy and feelings is also mentioned by E. Gadd in Professor E. Gadd's Research Journal, noticing that he can be unpredictable and that he does not always act in a sensible manner.

Gooigi is also vastly absent-minded, as shown numerous times in the games, like in the Garden Suites; rather than try to grab the Elevator Button, he stands idle, causing the button to drop to the bottom of the floor and forcing Luigi to take a wild ride back down. All his actions and emotions are copied from what he sees in other people, mostly Luigi, instead of acting by his own morals or feelings, which will explain why he is not always seen reacting in a logical or sensitive way.

Gooigi also does not understand and reacts with any type of dangerous situation or even potential death for him and his allies, even caused by himself, only focusing in a clear objective given, as seen in Professor E. Gadd's Research Journal when he does not stop using his Poltergust on E. Gadd even if this was going to cause his imminent death. E. Gadd was saved thanks to water falling over Gooigi, dissolving him, but he had no intention of stopping what he was doing at any time, even if this ended the professor's life, since he was simply commanded in that moment to use the Poltergust no matter what, not processing the situation of E. Gadd either. Another example is at the end of Luigi's Mansion 3, when Luigi is about to fall to his death from the destroyed Last Resort. Gooigi simply waved his hand at him, it was only through being saved by Polterpup that he survived.

He also does not seem to feel fear or pain in various situations, such as when seeing himself being melted by water slowly or when being hit with a giant hammer. He also does not seem to show importance or fight for control when E. Gadd or Luigi control his body during missions and testing, showing lack of will and free thinking.

This mindless behavior, as well of his emotionless stature, is likely attributed to the fact that it is just in his nature as a non-human entity, in addition to his purpose being only to help catch ghosts for the professor, and thus he has no other function besides helping E. Gadd in this task. If not controlled by anyone, he always ends up brazenly charging forward the enemy, scaring them off, not understanding E. Gadd and just copying what he have learned by several recordings on impulse.

Despite this, he can still be seen celebrating when clearing a room or defeating a boss in the games. Additionally, when being called back into the Poltergust, he will flash a thumbs-up to Luigi. This can also be a mimic mechanism, copying only what Luigi would have done in situations similar to the ones he finds himself at the moment.

As the game goes on, however, it's implied that it's possible that Gooigi is slowly developing a conscience and he is not only copying Luigi, as seen later on as he interacts more with him, even doing his aforementioned wave at the end. When Luigi, Mario and the others leave The Last Resort, he can be seen waving goodbye to his counterpart.

History[]

Professor E. Gadd's Research Journal[]

Gooigi was made by E. Gadd during the events of Professor E. Gadd's Research Journal after seeing that the Goo was an intelligent entity and was capable of the mimic of actions. This gives him the idea of using the Goo to catch ghosts for him. E. Gadd went to work to give Goo a humanoid form to be capable of such task.

He failed to give it this form until the professor remembered the biological data that the Pixelator captured when Luigi used it in the past. Taking that data and converting it into an electrical signal, he was able to then input it into the Goo, making it take the exact shape of Luigi and creating Gooigi.

E. Gadd successfully taught Gooigi how to catch ghosts thanks to various recordings of Luigi in his adventures, but E. Gadd also wanted to improve Gooigi's Goo-based properties to give him capabilities beyond those of a normal person. He then decided that he would need ghost energy from beyond Evershade Valley, sending him to the past to the first mansion, which will lead to the events of Luigi's Mansion (3DS). Sending Gooigi elsewhere could both make him learn more from fighting ghosts and he could also collect ghosts for him.

After his return and with the new energy collected, E. Gadd began to expirement these on Gooigi's material. He finally created a composition of Goo for Gooigi with a malleable texture that will give him the ability to slip between bars or pass through narrow pipes.

During the rest of his research, E. Gadd studied all of Gooigi's characteristics, abilities, and weaknesses with various tests. He also searched a way for him to control Gooigi, which will lead to the creation of the Poltergust G-00.

Luigi's Mansion (3DS)[]

Gooigi was sent back in time to the events of Luigi's Mansion in Luigi's Mansion (3DS) to assist Luigi on his quest and collect ghost energy. If the player manages to play with a another person who has a copy of the game, or with Download Play, they can play with Gooigi as the second player. If not, Gooigi will stay in the Lab, curiously staring at test tubes.

When the player finishes the game, the future version of Professor Elvin Gadd will check if Gooigi is being used or not. If not, the professor will look sad but he will say that you can use him in the future.

Luigi's Mansion 3[]

After the successful tests, in Luigi's Mansion 3 Gooigi is back at it again, brought by E. Gadd to the hotel with him and the new Poltergust G-00.

He now can be controlled by Luigi, he is stored in a container and can be used when pressing down the right stick. While that is happening, Luigi will be seen standing in place and sleeping unless in multiplayer mode. Gooigi can also help Luigi reach to objects that he can't reach like normal.

Characteristics[]

Since Gooigi is made out of malleable Goo, he is able to slip through objects like bars, spikes, and grates.

With his new level of viscosity, Gooigi is able to handle tasks that don't require too much effort, like opening the drawers of a dresser or a Chest. However, the effort to do things like turning doorknobs and opening doors is out of his reach.

Gooigi is very vulnerable to any type of fire or water and melts on contact of either easily. He dissolves upon contact with water or fire, but only with direct contact with liquid H2O will cause this reaction, for rooms containing vapor or steam do not dissolve him in Luigi's Mansion 3, unlike in Luigi's Mansion (3DS), where he does melt on contact with vapors.

Instead of having 99 HP like Luigi, he only has 25 HP. He Loses consistency when struck by powerful attacks, and while Gooigi is somewhat resistant to physical blows, he can not hold up to repeated or powerful attacks. This will explain the low amount of HP he has compared to Luigi. Contrary to Luigi, however, Gooigi can also respawn again whenever he wants to from Luigi's Poltergust G-00 once defeated.

He can create and change the Poltergust he is wearing, which in reality is part of his being, to any of the models created by E. Gadd, even using the same abilities of the inventions. This confirms that even though he needs help of the data from the Pixelator to maintain Luigi's form, he can also still modify his shape and abilities to some extent copying what he sees.

Trivia[]

  • The Poltergust G-00 is inspired by Gooigi, "G-00" being a pun in Goo, which is the material used to create him.
  • According to the game's producer, he can actually be eaten, similar to gummies [1], and is stated to taste like coffee.
  • There's a chance that Gooigi will get a spin-off centered around himself and other color variants, stated by the producer. [2]
  • E. Gadd mentions that he embedded a special chip into Gooigi in Professor E. Gadd's Research Journal. The exact location of this chip is unknown, as it's not seen in game either.
  • Gooigi almost accidentally ended the life of his creator when using the Poltergust. E. Gadd was thankfully saved due to Gooigi's weakness towards water.
