Caliban

Caliban is a mutant with the ability to detect mutants and know their powers. You first see him in the game working with Pixie, saving mutants who are in danger due to the Purifiers.

Caliban does not have a particularly large role in X-Men Destiny, making small appearances with only few lines of dialogue.Caliban is first seen after you save the little girl from Comander Hodge's men in the second mission when he is with Pixie.He talks about how the Purifiers are capturing the mutants and not killing them.He and Pixie then take the little girl to the X men to take care of her.Caliban is later seen when you go to rescue Pixie,you have to rescue him so he can track Pixie with his mind.You then find out that she is in the hellicopter    above,thanks to Caliban.

Trivia

 * Caliban, although appearing to work closely with the Brotherhood of Mutants, works close alongside Pixie (a member of the X-Men). This is rather curious, due to the fact that many X-Men and Brotherhood members continue to argue with each other throughout the course of the game.
