A friend with blue hair that has tufts resembling rabbit ears. He wears a gray hoodie and black pants. One of his eyes was turned into a black sclera by One previously due to a minor conflict. He is rude and rarely shows kindness, though he does show some to X. He and Two are bitter enemies with no intention of ever getting along. He can't even begin to understand why Two would take his contestants and think of killing them all. He doesn't try to befriend others. He still has some superpowers left that One took, but there's a risk of them going out of control if he's not careful.

He seems to have the strongest mental fortitude. He has tied-back yellow hair, wears green goggles on top of his head, and wears a long-sleeved white lab coat that looks very oversized. He carries a monkey wrench on his back. He is very friendly with Four. He tries to understand Two, but always receives unkindness in return. He rarely uses his left arm after it was hit by a falling wardrobe. He drinks coffee frequently and is generally kind and bright. His superpowers were taken by One, but Two currently possesses them.

A guy with long green hair who wears a top hat and drapes a jacket over his shoulders like a cape. He used to host a show with contestants he took from Four's show, but after Gaty was taken by One, his mental state deteriorated rapidly, leading him to kill the remaining contestants and become a serial killer. Now, he lives a life akin to a contract killer. He often seems tired. He has a terrible relationship with Four but thinks relatively well of X. He can be very sweet and kind if you aren't his target or if you're his friend—though that doesn't include Four. He still has his superpowers and even stole One's, making him excessively powerful, which leads him to somewhat loathe his own abilities.
