Fold

Gameoverse hasn't shown much of Fold yet, but from what we've seen in trailers, official art, and descriptions, Fold has a very chaotic and theatrical personality. He seems like the typical villain who enjoys scaring and mocking others while acting over the top.
It also gives the impression of being:
Manipulative and cunning.
Sarcastic, with a strange and somewhat awkward sense of humor.
Dramatic and eccentric.
Impulsive, but intelligent.
Very expressive and energetic.

It is implied that Fold was the one who guided Kit on his expedition into her world, as there was a piece of paper near her with instructions on how to win her game, and later there was another one near Malice and Chaos when Kit defeated them.

He, along with Miss Information, were sent to destroy Flappers' world after they both failed in their attempt to stop Kit and company from landing on the planet (which was originally going to be used to train Crab Girl).

Fold is a white humanoid with a paper-like appearance, a reddish/lavender eye with white sclera, and sharp, pointed teeth. It can mimic ordinary paper and has the ability to fold into a multitude of shapes and sizes.
