Nathiel Waters

Nathiel Waters is a dark blue fish that makes many cameos in some episodes. He is a dark blue fish with 3 purple stripes on his back and a purple fin. In some episodes (like Chocolate with Nuts) he is shown wearing clothing but in other episodes (like Fungus Among Us) he isn't shown wearing clothing.

In T.U.G.E.N, Waters is a character that people are confused why he is in in the first place.

Zobbes Version
Zobbes created Waters, And is a tough fighter overall. Waters had no GIFs for the attacks, So it's hard to tell what he looks like in the game.
