Sea Devil (Devil of the Deep)

A Sea Devil scientist went into hibernation with his people to avoid a "catastrophe". Sleeping for millions of years, the Sea Devil woke earlier, around the late 16th century, than the rest of his kind due to a defective hibernator, after which he took to studying how the world had changed during his sleep. After ten years, the Sea Devil rescued and befriended a human, Diego de Columba of Cordoba, who had washed up on the beach when pirates raided his ship and taking no prisoners. Unfortunately, the Sea Devil was later captured by pirates, one of him, in curiosity, activated his device which called a creature to awake from under the sea, proceeding to destroy the pirates' ship. Diego presumed the Sea Devil to have perished with the pirates. (COMIC: Devil of the Deep)
