Waylon Jones

Waylon Jones was born with a skin disorder, which made him have a crocidile-like aperance. He became a inmate at Arkham Asylum. Jonathan Crane (Scarecrow) was experimenting on him. Croc grew up in Arkham and was let out by Ra's al Ghul. He joined Scarecrow, and Scarecrow experimented on him. Scarecrow injected fear toxin in him, so if Waylon bit anyone, they would become injected by fear toxin. Then Batman defeated him and he fled to the sewers.
