Pomni has a very nervous, shy and paranoid behavior. In the pilot episode, she is shown to be frightened by her situation, even succumbing to denial, and shows signs of paranoia and deception. She does not remember her real name so she uses the alias Pomni.

Although his fighting technique may be a bit over the top, aiming to bite off more than he can chew, he remains humble towards his opponents and rivals due to their similar circumstances... Except for one, of course.

However, he does seem to show some concern for characters, offering them rooms, the sensation of food, and keeping their minds stimulated with the challenges. He also takes care of any "Abstracted" characters by sending them to a cellar and keeping everyone safe from entering The Void, bringing into question if Caine is truly evil, or good, or just doesn't understand human mental states.

He is a rebel, doing what he wants when he wants it. He's apathetic, sarcastic, and not too caring other's feelings or even his own imprisonment as in his own words, "fine with doing whatever, as long as he gets to see funny things happen to people." He often pranks the other humans, with his common victims being Ragatha and Gangle.

He is a tricky, conceited and overconfident boxer. Jax (or Jackrabbit) is the great champion of Fight Club, although many speculate if he deserves it.

Es un chico bastante energético y bromista, siempre lo verás causándole bromas a los que estén cerca, es fastidioso, narcisista, egocéntrico y no le importa si sus bromas llegan a molestarte. Aveces te hará dudar de sus facultades mentales ya que se caracteriza por ser un poco infantil. Adora los dulces.

Described as "the sweetest little optimist", Ragatha is mostly positive and constantly happy, as shown when she was stabbed in the head with a knife and simply brushes it off. Though this is mostly a measure to keep herself from going insane while trapped in the Circus.

She often butts heads with Jax, with the two being conflicting parallels of one another.
