Ridgeback Monster

An Indian Hill experiment that could be Killer Croc is a minor villain in the third season of Gotham.

History
Killer Croc is one of the escaped experiments from Indian Hill created by Hugo Strange. As the others, he is releases when Fish Mooney's truck crashes in Gotham City.

Six months after the crash, Croc robs a pharmacy at night and is surprised by the owner. The frightened man claims that he will not call the police if Croc leaves immediately but Croc grabs the man and throws him through the shop's window. He follows him onto the street but is then greeted by Jim Gordon, who holds a baton and tells him to come quietly. Croc instead grabs and breaks the baton and attacks Gordon, who attempts to fight back. Although he can hold his ground, Gordon is unable to really harm Croc due to the man's hardened skin. The fight ends when Croc is accidentally run over by a truck.

In the aftermath, GCPD Commisioner Barnes holds a press conference in which he informs Gotham about Killer Croc. Barnes claims that his men are still collecting pieces.
