Biollante's final form, both immobile and unplayable, is a fairly unique character in the game. She might seem diffcult at first, since she will only recieve damage when being struck in the mouth, but once the variety of her attacks become familiar to the player she is relatively easy to defeat with heavy use of the Atomic Fire. Like the rose form, her vines can be destroyed here; however, they regenerate so quickly that it's an unadvisable tactic.
