Of course, there were hints that he was actually born with a mutation that gave him the appearance of half-man, half-reptile), Killer Croc is a virtual powerhouse and has two pet crocodiles to do his bidding. With the strength of a crocodile (and a tail to boot), Croc is able to chomp and swim his way around Gotham. In this version, Killer Croc is even more reptilian than past versions and has a tail. He appears to be much stronger than Batman and much like a crocodile, he's able to stay underwater for long periods of time.

While Catwoman's interests are merely in cat-related fare, Ragdoll's interests lay wherever the money is. To Catwoman's dismay, this is also in rare cat-items: vintage animation cells, priceless artifacts and the main jewel of their battle, two 'Cat's Eyes' emeralds, hidden in a Gotham Clock Tower by a mobster in the 1930s. Though never found, it was enough to pique the interest of Ragdoll and Catwoman, falling into a trap set by The Batman.
