User blog comment:RaptorHunter/Killer Croc vs. Black Manta/@comment-2061886-20100829002942/@comment-2126736-20100831210738

There are several versions of killer croc, and I based his weapons off of his first appearance, in Batman #358 and #359 in 1983. He was more of a human with green scaly skin and massive muscles, but i understand the picture i have isn't that version, the picture is from the video game, Batman: Arkham Asylum, where he was more of a monster.
