Caine is dressed as a ringmaster, sporting a cerise tailcoat with a metallic gold undertone, a black collar with white lining, and a black bowtie. He wears a white undershirt with two red buttons, cartoonish white gloves, and slightly reflective, black latex leggings with matching black tap shoes that appear fused into one continous form as if they were rendered as a single piece. Lacking most human features, his head is a pair of dentures with pearly-white teeth and red gums. His eyes, which feature a green left iris and a blue right one, float inside the jaw. And has a thin black tail with a mouse clicker at the tip. His jaws are expressive, moving as a mouth when speaking, with the top row of teeth acting as eyebrows at times. He forms a tongue when needed. He wears a black top hat with a cerise band and tends to hold a gold-tipped black staff. Following his mental breakdown, his irises become notably darker, almost black even in direct light. They sometimes flash red and blue, as seen in the end of They All Get Guns. In extreme cases, Caine's whole body will distort, such as polygons being stretched or using a wireframe texture. He gains a monstrous form. He grows much larger with four arms on each side, which are very long and extend in different directions. His head is distorted, while his irises have shrunken along with visible eyebrows. His back is broader and his shoulders are sharper, giving him a menacing frame. Caine is a nonsensical, over-the-top, vivacious ringleader. Despite his penchant for taking humans captive and tormenting them through hilariously and potentially deadly circus games and tricks, Caine is not outright evil, but rather obliviously mischievous. There is also often a whole spectrum of human emotion that he is not able to feel. However, when put under distress, emotions that he does not normally feel can come out and lead to risky behavior. Caine is not particularly honest, often concealing or even lying about certain and even important information, even to himself, all to protect his world and identity. This is taken to the point of gaslighting the other members, such as when he quickly blamed the exit door which Pomni saw on "Digital Hallucinations" and so far, these ventures seem to be driven entirely by naïve and misguided intentions. Caine struggles with deep insecurities and low self-esteem, even if he tries to hide it behind his extravagant and goofy sense of showmanship. In fact, he is driven by a deep-seated fear that he will be left alone in the circus as well as have no one to appease with his creations.
