Caine

Caine is an A.I. who portrays himself as the ringmaster of the circus, maintaining the simulation and its residents, alongside his loyal assistant Bubble (who is a literal bubble, just with eyes and a toothy grin).

He is the highest artificial intelligence program in the simulation, due to the fact that he can create other AI, being able to levitate indefinitely, is the only one capable of reversing the glitch effect of those attacked by an Abstraction and is able to teleport himself and others to anywhere within the simulation, which includes The Void.

He appears to be responsible for the creation of all the NPCs in the circus, along with the entire Candy Canyon Kingdom, given that Princess Loolilalu refers to him as "God" and given that he can "delete" NPCs who wander into the Circus either intentionally or by accident, due to him being worried that losing track of who is human and who is an A.I. could cause severe problems later on.

Caine is dressed as a ringmaster, sporting a red tuxedo with a gold underside, black collar and bow-tie with white outlines. He wears a white undershirt with two reddish buttons on it, alongside white gloves and black leggings. Lacking most human features, his head is formed as a pair of dentures with pearly-white teeth and red gums. His eyes, the left one with a green iris and the right one with a blue iris, float inside the jaw. Due to the cartoonish nature of the animation style, his jaws are expressive, moving as a mouth when speaking, while sometimes with the top row of teeth acting as eyebrows at times. Similarly to Bubble, he forms a tongue when needed. To cap it off, he wears a black top hat and tends to hold a gold-tipped baton depending on the situation. Occasionally, he is seen wearing The Wacky Watch.

Caine is depicted as a nonsensical, over-the-top, vivacious ringleader. However, there is an aloofness about him and a significant disconnection towards the traumatic events that the characters around him are experiencing, illustrated by his forgetfulness of Zooble's criticisms of their own form and his adventures.

Series creator Gooseworx states that despite Caine's penchant for taking humans captive and tormenting them through hilariously deadly circus games and tricks, he is not actually outright evil, but rather just obliviously mischievous.[3] She also stated that "there is a whole spectrum of human emotion that he just doesn't feel."[4]

Caine is shown to be secretive at times, often concealing or even lying about information related to his 'unfinished work' to the point of gaslighting the other members, such as when he quickly blamed the exit door which Pomni saw on "Digital Hallucinations". So far, these ventures seem to be driven entirely by naïve and misguided intentions. Despite this, Caine appears to have at least some measure of morality. He does not appear to intentionally inflict harm onto the Circus members and does what he can to entertain them. He was also clearly depicted having a disdain to any form of cursing or swears which are always censored in the Circus.

Caine has often been seen having tense interactions with Bubble, another member of the Circus and an AI like him. The first incident is after Bubble eats his Angel Food Cake, to which Caine yells at him, calling him a parasite before popping him. Shortly after, as Caine is explaining the Gloinks to the crew, he gets agitated with Bubble's constant questions and pops Bubble once again. However, Caine does appreciate Bubble's company. While the rest of the crew is off on an adventure, Caine and Bubble are seen in a restaurant chatting amongst themselves.

Near the end of Candy Carrier Chaos!, he also expresses some degree of fear that he might lose track of who was A.I. and who was a player, which could lead to problems.

He expresses some degree of insecurity and self-esteem issues, appearing almost obsessed with the enjoyment of his players, leading him to attempt to appeal to Zooble especially due to their lack of engagement. When Zooble criticizes Caine's adventures (and how every other human refuses to criticize them for varying reasons), it causes Caine to have an existential crisis as creating pleasing adventures is "all [he exists] to do!" and "all [he is] good at." This crisis causes him to space out and twitch, while the circus glitches out around him, indicating that his own mental status can have an influence over the circus itself.

He is viewed differently by every member of the circus. While Jax believes that Caine cannot do anything intentionally malicious due to it "not being in his nature", others like Zooble believe that Caine is fully capable of doing such things if it crosses his mind given his power and the only thing that stops him is the fact that he likes the inhabitants and they should not try to push their luck, believing as long as Caine is pleased, any harm he does is purely accidental and will not have any reason to attempt anything intentionally harmful.

As the highest artificial intelligence program in the digital world, Caine is the most powerful entity within the Digital Circus and is the creator of all other A.I. in the circus. Due to this, he is viewed by his creations as "God", with Princess Loolilalu noting him through a ceramic window in her castle while Baron Mildenhall refers to the antagonist NPC from the horror-style adventure as "one of God's angels". Despite his immense power over the digital world, he has admitted that there are a few things outside his control and isn't fully aware of everything that happens:

Cyberspace Lordship: Being the ringmaster of The Amazing Digital Circus, Caine has almost complete control and rulership of it and its inhabitants and has no known master or superior to him. Despite this, he has admitted that there are some things that are out of his control, such as the minds of humans in the simulation. Cyberspace Nigh-Omnipotence: Caine appears to have complete control over The Amazing Digital Circus, with him being able to create, manipulate, and control anything within its boundaries. With his only current known limit being that he has no control over the minds of those who are trapped in it. Cyberspace Omnificence: Caine has been shown to be able to create anything, including virtual food, a random name spinner, and a virtual species called "Gloinks" along with the "Gloink Queen". In episode 2, he is responsible for creating an entire kingdom and its surrounding landscape, containing at least hundreds of NPCs, along with at least five new developed A.I. that are "57 times more immersive" than Gloinks. Virtual Reality Manipulation: Caine is shown to have complete control of the environment in the digital world. He can heal glitched characters, and put the Abstracted into the Cellar. Cyberspace Nigh-Omniscience: Caine is implied to have almost complete awareness of the digital world and what is happening in it. It is shown that he was aware when Pomni exited The Digital Amazing Circus into the void. He also somehow knew that Pomni used one of the exit doors. However, he does not have any awareness or knowledge of the Void and has a hard time being able to differentiate his own NPC creations from humans due to them all looking cartoonish, thus why he doesn't want any NPCs in the circus unless they're intended to be there, such as the Sun, Moon and Bubble. Cyberspace Sustainer: Caine is not only the master of the digital world, but also appears to be what sustains it as he admits to Zooble that being the ringmaster who makes adventures for the human inhabitants to go on is all he exists to do and is the only thing he's good at doing. However, when he learns from Zooble that he is "bad at the only thing he's good at", it causes his code to start contradicting itself, which in turns results in the entire Digital Circus to begin glitching out violently until Zooble manages to snap him out of it, resulting in everything going back to normal. Teleportation: Caine is able to go from one point to another within the digital world, as he was shown teleporting in and out of The Amazing Digital Circus, and saving Pomni by teleporting her from the void back into the digital world. Toon Force: Caine can manipulate his own body parts and proportions with ease and without harming himself. He can stretch, bend and warp his limbs, eyes, teeth and tongue to impossible lengths. Flight: Caine has the ability to fly, or hover in the air freely. He can also cause other characters to float/fly at will such as Pomni and Abstracted Kaufmo. Amorphous Eyes: Caine is able to control his eyes' shape and make them move around, as shown in POMNI WAKE UP TIME TO GO ON AN ADVENTURE, he played Hacky Sack with one of his eyes using the other. Fourth Wall Breaking: Caine was able to talk to the audience in the intro of the PILOT.
