Porphyrion is portrayed as leader of the Titans who appear during The Battle for Mount Olympus. He draws his power from the earth and appears to be composed of plant roots and dirt (maybe rock), he is humanoid in form. His form is later altered by Hera to appear with horns, empty wings, as well as one large 'trunk' instead of legs. Porphyrion is the only one of the 4 to actually possess the Cronos Stone and he does so with much vigor. He meets his end when he is dropped into Tartarus by Hercules from the sky.
