The Sky Leviathan is a skeleton like leviathan in the YouTube and Newgrounds animation web series Gwain Saga. It would one day attack one of Luna's robots while Geo and Marlow where inside a mountain and would ram into the two of them shortly afterwards. Geo and Marlow would grab onto the leviathan as it flew through the air, with Geo trying to use his strength to take it down. Geo's punches, however, wouldn't damage the leviathan, which would retaliate by blasting the two of them with magic attacks, sending the both Geo and Marlow flying into the air. The Sky Leviathan would then try to attack Marlow again, but its attack would be blocked by Geo, though it would knock him out in the process. The Sky Leviathan would try to attack the two of them one more time but would be stopped by Gwain, who would casually blast it away, saving Geo and Marlow. Its body would later been seen in 006.
