Porphyrion

Porphyrion is portrayed as leader, 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, and one large 'trunk' instead of legs. Porphyrion is the only one of the 4 to actually poses 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.
