Sever is a shark-like Vandal. He is the only Vandal who has not tried to overthrow Kalus yet, but that may be due to his not very bright nature. Much like a shark, he often thinks about food. He has a very keen sense of smell though, and can detect life forms from over a mile away.
On Vandal he is the leader of a group of shark-like Vandals called the Aqua-Jaws with whom he communicates by a language of high pitched screeches much like whales and dolphins do.
His vehicle is the Water Slaughter, which has powerful jaws with grinding teeth, is able to fire tooth shaped projectiles, and outmanuvers other vehicles underwater. It was destroyed in Rumble in the Jungle.
