Well, the first thing that got me interested in him was his weapon and basic character concept - being an Angel is a plus with me from the beginning, but the bow that splits into two swords was just too cool to ignore in my eyes. Since then, the fact that he appears to fit my preferred character type (light and quick) and some of the awesome abilities he has and which I can imagine doing with him (using extra jumps to rain arrows from off the side of the stage or from above, or using his up-B to fly all the way under a stage to the other side) has kept me interested in him, so based on that I'm going to try him out and see if I want to main him.
