Well, unlike the movie, he's not a pirate that steals ice, rather, he's an air pirate that happens to have a big ice-elemental hangup.
Revised character design for an original idea set in the Guilty Gear universe. He used to look a lot like Tidus (note the name similarity) but it didn't make sense. Now, I think he looks kinda like a palette-swapped Jack Sparrow, but at least he -looks- like a pirate now.
And I promise, he's /way/ less obnoxious than Johnny.
