Overview

Parasite, once Dr. Simon Lasker, was a brilliant neuroscientist whose obsession with human consciousness led him down a dark path. After experimenting with forbidden neural energy, he became fused with a sentient parasitic entity that feeds on psychic energy. Now known as Parasite, he seeks to absorb the strongest fighters in the world to achieve ultimate mental supremacy. With his ability to steal fighting styles and memories, he has become one of the most dangerous and unpredictable adversaries in the Street Fighter universe. His presence disrupts the balance of power, turning warriors into hollow shells of their former selves.

Personality

Cold, calculating, and deeply introspective, Parasite speaks with a calm, almost hypnotic tone, often quoting philosophical paradoxes mid-battle. He views humans as vessels for knowledge rather than individuals, believing that true evolution comes through assimilation. Though detached and emotionless on the surface, he occasionally reveals flashes of melancholy—echoes of the man he once was. He is not driven by greed or revenge, but by an insatiable need to understand and transcend the limits of the mind. He respects only those who challenge him intellectually and physically, seeing them as worthy hosts for his next transformation. His demeanor is eerie and unnerving, making opponents question whether they are fighting a man—or a memory.

Netizen Review

Parasite is one of the most terrifying villains in the Street Fighter roster. His psychological warfare makes him feel like a real threat even outside of gameplay. Fans praise his unique design, lore depth, and the way he challenges traditional fighter archetypes. His 'mind absorption' mechanic adds a fresh layer of strategy, and many consider him a fan-favorite DLC character. Some critics argue he’s too powerful in story mode, but overall, he’s hailed as a masterpiece of narrative villainy and thematic cohesion.
