De Loco (デ・ロッコ) is the Admiral of the Fifth Fleet of the Armada. A mechanical freak who develops multiple special weapons. He rides on his flagship with numerous anomalous cannons, as he has absolute confidence in the machinery he has developed. Therefore, if anyone tries to damage his machinery, he would chase him to the end of the world to torture him to death. He outwardly displays a mean and vulgar attitude, and in his innermost thoughts he especially thinks of himself a genius and all others incompetent pigs. He likes to thoroughly tease those weaker than himself.
Outside of the people of Ixa'taka and characters introduced in Skies of Arcadia Legends, De Loco is the only character with unnatural hair color. It's possible that the people of Ixa'taka have hair dye, so during De Loco's tenure there he dyed his hair, suggesting purple is not his natural hair color.
