Eric

Eric the Whirlwind (つむじ風のエリック) is a mercenary in One Piece. He is an anime only character, who was the main antagonist of the Warship Island Arc.

Appearance
Erik is a slender man with a square-like face, long sharp fingernails and a purple hair, shaped like a hook. He wears a grey blazer and pants with redcolored sides, and a purple striped shirt underneath. On his chest, he wears something that looks like a golden brooch shaped like a birdwing, and he has two earrings with pearls hanging underneath them.

Abilities and Powers
Eric was skilled enough to be hired by Nelson, and has shown to be quite acrobatic, jumping to evade Monkey D. Luffy|Luffy's attacks. He also seems to be confident of his own abilities, as he is undaunted during his first encounter with the Straw Hat Pirates and does not show any sign of fear upon learning that Luffy is also a Devil Fruit user, which apparently scared the marines with him.

Devil Fruit
Wielding the power of the Kama Kama no Mi, Eric is able to use his lengthened fingernails to cut through the very air to create razor-sharp gusts of varying size. Eric proves himself to be a dangerous opponent when ultimately facing Luffy, inflicting multiple wounds against his opponent, but he proves to be no match for Luffy.

History
As a mercenary under Nelson's command; he is ordered to retrieve the runaway girl Apis and capture the legendary Sennenryu, Ryuji. He would later betray and (supposedly) kill Nelson. He would track down and follow the Straw Hat Pirates the entire time they was on Warship Island, as he fought against Luffy and his crew in a bid to try to obtain the Sennenryu which will aid him in making the supposedly magical 'elixir'. He manages to deal a significant amount of damage to Luffy, but is defeated when Luffy sends him flying off the Island with his abilities.

Eric would later reappear once again to obtain his revenge just as the crew began to climb the Reverse Mountain, leading to the infamous Grand Line, but found himself tipped over the edge of the Going Merry and into the water by Nami before a battle could even begin.

Translation and Dub Issues
A running gag throughout that arc was Luffy and the others would mishear the name of his Devil Fruit (Kama Kama) as Okama Okama, making them think Eric was a crossdresser calling him "Eric the crossdresser" who ate the Okama fruit. In the FUNimation dub, since the name of his Devil Fruit was changed to the "Sickle-Sickle Fruit", the joke was changed to them mishearing the name as the "Sicko-Sicko Fruit".

Trivia

 * In the concept art for Eric, it was shown that he liked to file his nails to keep them sharp.
