Caliban is a Mutant Taylean, partnered with SaberX. He is a cloned sample of DarkusWolf28's Darkus Mutant Taylean.
A Bakugan with a strong sense of instinctive battling knowledge. With strengthened shoulder and impenetrable armor protecting his head, Caliban defends against attacks as he prepares for his next move.
Caliban has a relatively silly personality (making him the center of others jokes) demonstrated by his original reason for brawling, which was so he could be a super star battler, like in the movies.
He has also demonstrated almost no sense of direction. This was especially made clear in the episode "A Mu-tant Arrival" when he was trying to go to, Saber's room, but ended up walking into the girls washroom (completely opposite to his intended destination). Though when in battle he is shown to have a strong sense of instinctive battling knowledge. He doesn't always remember what he's told, and is kind of a rouge. Who can't be trusted to follow everything he's told, unless it's really important.
Caliban was cloned from DarkusWolf28's Darkus Mutant Taylean, when she asked Firestormblaze to do her a favor, and watch over her Bakugan for a while. Her Mutant Taylean was a rare type (at the time), so he decided to take a sample. He later gave it to SaberX, and he then created another Darkus Mutant Taylean, which they named Caliban. After that Caliban participated in many battles, with SaberX and his Darkus team.
