Megalo

Megalo (メガロ) is a shark that lives on Fishman Island. Not much is known about him except that he might be in the service of Neptune.

Appearance
He has a usual shark design, the only difference is that he wears a shirt from the Criminal fashion line.

Fishman Island Arc
Megalo was first seen being freed from the Kraken accidentally when Luffy attacks it. Later, he tells King Neptune about the pirates, and the king invites them to Ryugu Palace, apparently as an act of gratitude.

Trivia
