Megalo

Megalo (メガロ) is a shark that lives in Fishman Island. Not much is known about him.

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

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 Ryuuguu Palace, apparently as an act of gratitude.

Trivia
