The god of life. Armadon fights to defend Urth and prevent its destruction from the hands of the Evil gods. He is a semi-bipedal dinosaur with Styracosaurus-like head and limbs, a series of spikes in his back, and a tail whose tip is a combination of an Ankylosaurus' tail club and a Stegosaurus' thagomizer. According to the description on the package for Armadon's action figure, his species is "Tristegasauratops". Armadon has the easiest combos, but has a short reach. His domain is the Hollows, and his worshipers appear dressed in light green rags.
