Biollante

"Biollante is a terrifying example of mankind's ability to unleash horrors upon the world. The result of anti-monster mutagen experiments gone horribly awry, Biollante is a patchwork mix of human, plant, and monster DNA. Biollante's sheer height and mass make her the largest known monster by a good margin, and if it were not for her limited mobility there is little doubt that she would have established herself already as Earth's most powerful monster. As a mutant, Biollante holds no special allegiance to any of her genetic kindred-though she does seem to harbor special animosity towards Godzilla. Biollante's quick-extending vines and corrosive poison spray make her a threat at range, while her massive jaws and incredible strength make her deadly up close."
