Omega Red

Omega Red is a fictional supervillain from Marvel Comics, primarily an adversary of the X-Men. Originally a Soviet assassin named Arkady Rossovich, he was turned into a bio-engineered weapon through experiments that granted him enhanced strength, stamina, and the ability to produce deadly "death spores" from his tentacle-like arms. These spores can weaken or kill opponents, making him a formidable foe. Omega Red also has a life-draining ability linked to his carbonadium tentacles and can regenerate from injuries, making him a persistent threat in battles against superheroes.
