The Licker is a recurring enemy in the Biohazard (Resident Evil) series, first introduced in Biohazard 2. It is a grotesque, mutated creature resulting from the further mutation of zombies exposed to the T-virus. Characterized by its exposed brain, elongated tongue, and ability to crawl on walls and ceilings, the Licker is both fast and deadly. In the game, it serves as a formidable obstacle for the protagonists, heightening the tension and horror with its sudden, silent attacks.
