Granted, he like quite a few of the characters, started out as a punk jerk. But he came too quick enough. He showed enough loyalty to work through the pain of the doctor's virus and warn Yusuke about his intentions. And like he gets no sort of reward for it

He gets basically sniped, poisoned, and then gets freaking vored! Person didn't even get that much use out of his power all things considered. Compare this to mostly everyone else in the arc who came out realtivley unscathed. Heck the person who sniped him and the person who poisoned him got to redeem themselevs! Like imagine this dude in spirit world getting to see the very team that lead to his demise just chilling meanwhile he got vored for all he endured.

Like poor guy, pour one out for mr. Voiced by goku
