Jonathan Cartwright, nicknamed Mouse by Alice, was the son of August Cartwright and a member of the Wonderland Gang with the hobby of stealing skin from dead people and assuming their identities. Eventually, he was killed by Alice after trying to abandon her.


Since kid, Jonathan was capable of perfectly recreating all aspects of anyone's personalities and mannerisms. After he was disfigured during an accident, he met Beth Kane and they developed a sibling-like relationship. Eventually, he became obsessed in assuming persons' identities by wearing their skin and was sent to Arkham Asylum. He then joined Beth's Wonderland Gang.[4]
