Wotans

Wotans are a crossbred species between a giant and a fishman.

Appearance
Wotans are not as big as actual giants, but they are still very big for human standards. Their size is roughly little bigger than the Kairiki Destroyers, whom are considered as "oversized ants" to pure giants. In the anime, their size is greatly enhanced to proportions similar to actual giants.

The Wotans' fishmen genes also carry over to them. This grants them very powerful strength and the ability to perform amazing feats underwater. They however seem to have far less apparent fish features than a true fishman.

History
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.
