I believe he is my lowest level guy. One more play session with him would have brought him to level 12, and the ability to slot dual-origin enhancements. But once the closure announcement had been made, I tended to spend more time with my higher level folks.
I like the color combination used for his costume. His chest emblem is kanji for "water". He likely would have remained a villain; rogues tend not to be insidious. At some point I may have fleshed-out his description. Right now it is simply emotive with no actual backstory.
