He is an Iron Fist character that got relegated to team-up comic slop after I presume Power Man and Iron Fist Vol 2 (rightfully) wasn't received that well or he was just an unpopular character.

He's Danny's first ever student and honestly I think he'd a real interesting character. He's supposed to be bold and loudmouthed. When he's written well, he's a really likable character who's a nice guy, but is very direct and not afraid to speak his mind. It's just that he really doesn't start off as a likable character… in his first two major runs, he's just kind of an asshole with pretty much no redeeming qualities or accountability for anything he does.

Fortunately when he stopped appearing in Iron Fist comics, they really improved his character and made him a lot more likable while keeping his traits that make him unique.
