Living Warhead is the final boss of one path in Contra: Hard Corps. It is a missile armed with the Alien cell stolen from the Research Center that mutated into this abomination. Like many things in Hard Corps, it appears to be inspired by the alien from John Carpenters 1982 horror film, The Thing.
First, it sprouts huge clawed, skeletal arms from its left and right sides. These will spread out and then reach down to swipe at the player. After its arms are blown off, a long, snake creature will appear from the bottom of the main body, the tip ending in a hideous human face. The mouth will spit out a swarm of maggots, which will slowly crawl towards the player, then the face will open up, revealing an enflamed red core. This is its weak spot. After a few seconds it will close up, then the head will sweep to the opposite side of the screen and repeat its pattern.
