Synopsis for the TV Cartoon The Return Of Nepto

Nepto and his Viking raiders are awakened during a fierce lightning storm after centuries of slumber in suspended animation. As they had attempted to do in the past, the Vikings converge on Atlantis in aid of making Nepto its new king. By use of his magic trident, Nepto is able to trap Aquaman and Aqualad in a cave, but Tusky and an octopus are able to rescue them, just in time for Aquaman to prevent Nepto from cracking open the dome of the underwater city.
