Cuboid (and Cap)

Cuboid is a bit of an interesting character. He was originally going to be the main antagonist of Johanis, but he was replaced by Mind Guy after ties were made with Weirdest Object. He now simply exists as a background character, at some point in time having owned the realm of Hell. He was somehow captured by the CSP Foundation during his reign.

The basis of Cuboid's character was entirely planned out, having similar attributes to Bill Cipher of Gravity Falls, having similar geometric shape and demeaning personality. His hat was also originally a seperate being, an alien of some sort.

Appearance
Cuboid is a flat rectangle with a basic face and limbs. He can grow extra sets of arms and devil horns if necessary, but usually goes with a generic, cartoony look. He sometimes also has a devil tail and is surrounded by flame, if riled up. He is naturally noticeably larger than Bill Cipher.

Cap Toppat
Cube's hat is a short, black top hat with a single, purple, cat-like eye called Cap. The hat has a large array of retractable spider legs, but most often keeps them inside his head. He usually chooses to float a couple inches off the top of Cuboid's head.

Abilities
Cuboid has the ability to float, wield telekinesis, produce lasers, and do most anything while on Earth, as the place is "weak". He can also shapeshift and duplicate, even shapeshifting these duplicates for maximum trickery. He can possess entire towns at once, turning them into backwards, demented monsters.

Cuboid's story
Cuboid's story, canonically to the series as of right now, is he tried to attack the Snowball Fight Plateau by opening a dimensional door there, but was halted by CSP. Mind Guy soon took over his role with his own takeover.

Cuboid is now imprisoned with his hat in a CSP building. Not much else is known about the matter, but apparently Cuboid hasn't tried to escape yet, because if he did, he would.
