Gus

Gus in an octopus who lives in the waters surrounding the island.

Story
Gus is first seen in IL10, after Braxton finds them in the water. Gus tells Braxton that something is trying to trick them, they've passed by its house many times, and that's where she went, down the rabbit hole. Gus is presumably referring to Sop, and Eleanor's dissapearance after seeing Sop in the cave. Gus also says "old god bad, phone call sad", angering Edgar, and tells Braxton they can go back to the island. Before he leaves, Gus tells Braxton their name, and that they will meet again.

Gus is next seen five videos later, saying Edgar was the first who filled the void with a world of life, and his body disappeared after something infiltrated his mind. After saying only Yotis can free him now, they introduce the four bosses by name - Dishneck, Sentinel, Wormnose and Emissary - and gives them another task.

In IL17, Gus turns off Sop's movie Babaptism, telling Edgar not to fear and that Yotis has already occured. They say that while Edgar was dormant, "they" finished the game for him, and he can still get the good ending with the help of Yotis. They tell him that the rest are waiting outside, and then fade away.

After Theresa leaves, they meet up with Gus, who asks what they're doing out at sea. When Theresa relays that they're looking for Susanna, Gus tells her that she's under the weather, but they can pass on a message. Gus also wishes they could help Theresa get back to the mainland, but they're under the weather as well, and when asked what happened to their arm they say they wrote a book about it. Gus tells Theresa that Edgar was the first, but in a way is also the ninth, but it doesn't make sense to Theresa. Later we see Gus's book - it shows Gus when they were young, then them surrounded, then what happened to their arm, which has three prongs and a face on it like Sop.

Il25 begins with Susanna talking to Gus, telling them they need solid salts, which Susanna gets from Braxton. However, though according to her magnifying glass they save Gus, Theresa tells them she saw Gus floating unmoving in the water on the way to the Fish Mouth. Susanna promises to build a shrine for Gus when they reach the mainland.

Character
Gus is an orange octopus, with two black eyes, a large nose and pink lips. They have one damaged arm, which becomes grey over the course of Illusion Lock. In their final appearance, they are paler, and have eye bags.

Trivia
