Killer Croc is one of the Big Figure Pack characters in LEGO Dimensions 2: The Rise of Enoch, from the DC Comics franchise.
Waylon Jones was born with a disfiguring genetic skin disorder which gave him scales. Due to this mutation, Waylon was abandoned by his parents as a child and constantly bullied until one day he broke and attacked the bully before running away to the carnival. Having gotten a job as an alligator wrestler in a side-show, Waylon was given the stage-name of Killer Croc but the amount of mockery and shunning he got on a regular basis took a toll on Croc's sanity and made him turn to crime. As a criminal, Croc sharpened his teeth to points and used his immense size and strength to gain an advantage in the criminal underworld. Though he has average intelligence, Croc has super strength, accelerated healing, is a strong swimmer, hardened skin, and powerful jaws thanks to his reptilian genetics.
