Wotan

Wotans (魚巨人 (ウオータン)) are an interbred species between a giant and a fishman. Wotans are not as big as actual giants, but they are still very big for human standards. Their fishmen genes also carry over to them. This grants them very powerful strength and the ability to perform amazing feats underwater.

The only known Wotan is Big Pan of the Foxy Pirates. His fishman heritage is a mud-fish, which grants him a slippery skin that is resilient to most attacks.
