Bio: Born in the slums within the everglades of Florida, Waylon
Jones had a rare condition that gave him reptilian-like skin. Viewed as
an outcast, he became a thief and was placed in a juvenile hall. In
juvenile hall, Jones killed an inmate with his bare hands who made fun
of his appearance and was sentenced to jail. Paroled after 18 years, he
found work as a professional wrestler and took the name "Killer Croc."
He stole the wrestling promoter's money, escaped to Gotham City and
became a master thief, extortionist, and murderer. Although primitive
and no genius, Croc is one of Batman's strongest enemies. After numerous
arrests, Croc is deemed insane and sentenced to the violently disturbed
ward within Arkham Asylum.
