Nuhn - spirit of primeval water

Nuhn is a villain that appeared in the cartoon series "Mummies Alive!".
Nuhn is the spirit of primeval waters, described as being greater than all the rivers and oceans of the world combines, who was summoned by Scarab after he tired of dealing with "middle-spirits".
Nuhn manifested his power by flooding the area before transforming into a strange humanoid made of water - he instantly showed a very annoying, very arrogant personality and when Scarab tried to get him to reveal the location of the fountain of youth he mocked the sorcerer by saying the fountain was simply a myth.
However when Scarab threatened to send Nuhn back to the realm of the gods he changed, begging to stay so he could flood the world again - so Scarab agreed to keep the watery trickster in exchange for Nuhn attempting to capture Rapses for him.
Despite being a god Nuhn was more comic-relief than cataclysm and he continually failed to capture Rapses or even get his attention.
However Nuhn eventually ambushed Rapses when he was visiting a water-park, which of course gave Nuhn a great advantage and things only got worse as the confrontation intensified as Nuhn simply began absorbing water from every available source to grow larger and more powerful, betraying Scarab as he declared his intent to destroy the entire world - starting with Rapses.
However in the end Nuhn was defeated when he was lured into a skating rink and was frozen solid before shattering as his spirit was returned to the realm of the gods.
