Mero

Mero (メロ) is a smelt-whiting mermaid and an employee of the Mermaid Cafe.

Appearance
Mero is a young mermaid with long, flowing blue hair, with a yellow flower attached to the right side and blue eyes. She wears a revealing purple flower pattern bikini.

Personality
Like all other mermaids, Mero is kind and caring, and is apparently fun loving.

Abilities and Powers
As a mermaid, Mero can breath underwater, speak to fishes via sonar waves, and they are generally considered the fastest swimmers in the world. She also appears to be a skilled dancer.

Fishman Island Arc
Mero and her friends first appeared in Mermaid Cove, welcoming the Straw Hat Pirates when Keimi brought them there for a visit. When the three princes arrived to inquire the crew's illegal entry into Fishman Island, the mermaids denied the crew was there, hiding them. However, when the crew's presence were made known anyways by Sanji's nosebleed and Hammond's attack, the princes made it clear that they were simply trying to deliver Jinbe's message to Monkey D. Luffy.



After Ishilly, Fillonce and another mermaid were kidnapped by Caribou, Mero and the others wondered where they went off to and they had no clue of what happened to them. The only thing they did know was that Ishilly was opening a barrel.



After the civil war between the Straw Hats and the New Fishman Pirates ended, Mero and her friends danced at the Ryugu Palace banquet in honor of the Straw Hats' victory and saw them off when they departed to the New World.

Further Appearances
Some time after the Straw Hats left, Mero and her friends witness Caribou attempting to kidnap a helpless mermaid.
