Venom

Venom (ヴェノム) is Diablo's direct subordinate and a Black Colored Daemon, belonging to the Black Numbers, however unlike Testarossa, Ultima and Carrera he doesn't dare to question his superior's orders. It is said that he is very young but was born with a Unique Skill, making him a Unique Daemon. Venom has one hundred subordinates at his disposal and when he encountered Diablo in hell, his stubborn disposition in the face of continuous beatings made the Black Primordial think he might be useful to Rimuru.

He is also a reincarnator similar to Rimuru.

Appearance
He looks like a punk rocker.

Trivia

 * Venom is named after the Hennessey Venom supercar. This follows the pattern of many of the Daemons being named after cars.
