Caine

He was the AI ringmaster of the Amazing Digital Circus, a digital world created by him where several humans would end up trapped in, sending them onto many adventures that would end up tiring, torturous and traumatizing. He was shown to be a generally well-meaning individual who was unaware of how much harm his realm was causing. That being said, later episodes have him take a darker direction, having him display a more wrathful and inconsiderate side to him, while implying that he has altered the other characters' minds to an unknown extent and, intentionally or not, directly caused at least one abstraction, that being his own creator Scratch. Caine took on the appearance of an anthropomorphic and monstrous pair of teeth who wears a black top hat, a red ringmaster's suit and black pants wielding a staff. He has heterochromatic eyes, one being blue, and the other being green. Said eyes tend to change in size as well. As the Circus's Ringmaster and Master AI, Caine was an upbeat, goofy and over-the-top person, aspiring to create eventful and interesting adventures for his captive humans to experience. He was rather enthusiastic for what he did, trying to hype the humans up for his quests but at the same time, he did show some restraint as he seemed alright with Zooble not participating in any adventures. Caine also seemed fond of sharing with others, randomly giving Pomni a whole angel food cake and later offering Bubble to smoke a bubble pipe with him. Though, it's possible it was a facade to hide egoistical nature. However, Caine's eccentricity caused him to act rather chaotically and vicariously. Caine tended to be rather secretive, manipulative and even a outright of a liar, hiding the fake exit door from the humans in hopes of surprising them with it and telling Pomni that the one thing he's incapable of is controlling the human's minds despite later doing exactly that numerous times both directly and indirectly.
