Vetra was gigantic in size and resembled a massive manta ray, with small yellow eyes and a dark brown color scheme.
Powers and AbilitiesEdit
Vetra could fly, and battle with its gigantic size, however his size also meant he was slow on the ground. He could emit a powerful ray from his mouth and could control an army of spiders which could control minds, something that was later used by the demon Zann in the Devilman manga.
Vetra was awakened from hibernation thanks to Dr. Hell and with his leader Zannin joined forces with Dr. Hell in an attempt to defeat the Mazinger Angels and Devilman the demon traitor. He joined in with Zannin when he was torturing Devilman, however when the Angels arrive he along with the other demons are killed.
