Monster X (Final Wars 2004)
Monster X (Final Wars)
Monster X (モンスターX) is the supreme biological juggernaut unleashed by the extraterrestrial Xilien invaders in *Godzilla: Final Wars* (2004). Concealed within the core of asteroid Gorath hurled directly toward Tokyo, Monster X emerges untouched from the celestial impact crater in Shinjuku as an imposing, skeletal bipedal warrior armored in jet-black biomechanical hide and adorned with bleached skull pauldrons. Possessing lethal martial arts grappling reflexes and firing destructive Gravitational Light beams from his crimson eyes and shoulder skulls, Monster X is the sole adversary capable of matching Godzilla blow for blow during the global gauntlet. In the climax of the conflict, Monster X sheds his bipedal shell and undergoes an awe-inspiring metamorphosis into **Keizer Ghidorah** (カイザーギドラ) — a colossal 100,000-metric-ton quadrupedal golden three-headed dragon wielding levitating Antigravity beams and vampiric energy-draining fangs.
