Crailer is one of Hero Factory's top scientists and he helps Team Rook with their gadgets and gizmos.
Jack Crailer was once a regular hero, but his last battle lost him most of his limbs. When he got back to the Hero Factory, and had been repaired, he tried to make his own XL form. The rest of the Heroes thought he was crazy for doing so himself, instead of having this process performed by the Assembly Tower.
Abilities and Traits
Back when he was a normal hero, he knew several styles of martial arts, such as Kung Fu and Judo. His XL form can jump well, is very strong, and possesses a gun for a hand.
