The God of Skypiea, an island in the clouds above the Grand Line, Eneru takes his title literally, forcing his followers to worship and serve him. Eating the Rumble Rumble Fruit gave him the ability to manipulate, generate, and transform into electricity. Additionally, he is also able to use Mantra which allows him to predict anyone's movement and to sense anyone's position within a certain range.Beautiful cosplay!
