Chris Morales is the drummer in the band Subdigitals (previously known as the Subsonics), and the nephew of Jim Morales. He made his first appearance in Opening Act when he came to Kadic looking for fresh new talent to use as the Subdigitals' opening act. He, however, get disappointed when he found all the students in the auditions are not talented. After he hears Aelita's demo mix, Chris believes she is the talent he is looking for, but he can't find her. After he is dragged into a fight with one of X.A.N.A.'s Polymorphic spectres (imitating himself) he fights besides Jim and helps Team Lyoko before his memory is erased by a return in time, after which Jeremie hands him Aelita's mix personally and tells him where to find her.
Chris appears twice after Opening Act. Firstly in Crash Course, where he judges the finalists with the other members of the Subdigitals, and again in Music to Soothe the Savage Beast where he performs at the concert after the opening act performed by Aelita. After that, no mention is ever made of him or his relation to Jim again. Since Chris and Jim are of a similar age it is likely that Jim's sibling is much older than him.
Chris seems to be a key member of the Subdigitals as he says the record company will come down on him if he cannot find new talent.
He shows authority in the decisions of the group as shown in Crash Course.
According to Chris, the record label made them change their name.
