Migi

Migi stands out as one of the most compelling characters in Parasyte. Originally attempting to seize full control by invading Shinichi Izumi's brain, Migi was forced to settle in his right arm after the takeover failed. Devoid of human emotion at first, Migi operates purely on logic and an instinct to survive at all costs. Through relentless self-education, Migi rapidly develops remarkable intelligence, and what begins as an uneasy coexistence with Shinichi gradually evolves into a genuine partnership—one forged in the heat of battle against other parasites that prey on humankind.
