Canned Cain is a man in a green suit of futuristic-looking armor. He has pants with a camouflage pattern on them, a pair of big boots and a grey helmet with advanced light blue glowing optics. Despite his armored appearance, he has the same health as every other character.
Canned Cain bears a striking resemblance to the Doom Marine, protagonist of the Doom series of first-person shooters. This is more apparent when many people thought the image with the Khnum was a Doom-related screenshot.
