The 'Zombie' refers to the common infected enemies encountered in the Biohazard (Resident Evil) series. These creatures are humans who have been exposed to and transformed by the t-Virus, a biological weapon developed by the Umbrella Corporation. Zombies are notable for their slow, shuffling walk, insatiable hunger for flesh, and relentless pursuit of survivors. They serve as the primary antagonists and obstacles in the early Biohazard games, embodying the horror and danger of the viral outbreak faced by the protagonists.
