Blueberry (Inanimate Insanity)

Blueberry is shown to have little to no self confidence, and is quite pessimistic, lazy, and depressive. He is likely an introvert, being revealed when he arrived at Indefinite Island. He thinks of himself as an optimistic person who helps other people be their best. However, he also has a dark side, as shown in Blue Buried, because he faked his death, made many suspects, and used inspiration from Candle's meditation. Blueberry is very tactical when he is motivated, with him faking his own death very strategically so that he could rejoin the game, showing that despite his blue demeanor, he's secretly a huge threat. He's also shown to be egotistical, as he was constantly gloating about his victory. However, as he said during elimination: "I'm gonna keep running till they turn out the lights.'' And at the end of every episode, the lights get turned off. So presumably, his huge ego is just an "aftershock" after fooling everyone, or this is a play on the fact he "functions best in darkness".
