Queen Leech

The Resident Evil Zero final boss was basically a giant humanoid mound of sentient leeches. It had control over all other leeches in the Training Facility. In its first form, it attacks by hitting, grabbing, or throwing a character. After enough damage is given it mutates slightly, giving it more attack power and defense. After enough damage it is rendered unconscious and gives up the silver and gold keys that open the blast doors covering the emergency exit shaft. The queen leech has a second form in which it loses most of its human form to become a massive green creature with multiple tentacles and a massive flower-like organ in its back, which continually secretes acid. In that form, it has two main attacks, in which it rams the player character and spews acid from its flower-like organ. It is also invulnerable to all weapons and can only be killed by opening the four emergency helipad shutters to let in sunlight, whose ultraviolet radiation passes through its cells, burning them with a high degree of proficiency, making it highly unsuitable for general use as a biological weapon. Upon the sunlight consuming its body, it was terminated by Billy Coen.
