Fishman-Beast

Explanation of Field Power Sources, with Fishman-Beast-Type (魚人獣族) mentioned in the "Ocean" (海) box

Fishman-Beast (魚（ぎょ）人（じん）獣（じゅう） Gyojinjū) is a Type in Duel Monsters in the Yu-Gi-Oh! manga. It was not included in the Yu-Gi-Oh! Official Card Game or any of the video games.

Fishman-Beast was mentioned in an explanation of the different fields on the Duelist Kingdom island. It was one of the Types that benefited from the Ocean field.

Based on the name, these monsters would perhaps visually have been anthropomorphic fish. Such creatures from this era of the franchise include "Great White", which was released in the OCG as a Fish-Type, and "Half-Fish Man" which has never been physically released.
