Shenn kinda fits this because he's just like this undead soldier who's usually down for a fight but if he's fishing or at the bar and you're like 'hey bro can you go kill this dude he's causing trouble', he is not about to move for that. Nope, sorry bud, go find a different anti-hero to do your dirty work. This guy's busy doing nothing in particular.
Dalthundolar and incidentally his as-of-yet un-drawn/uploaded husband, Ralimanth, both fit the antihero thing too, I think. Dal's undead and Ral's a demon hunter who were bloodthirsty af, but both of them got sick of fighting and just ran off to a mountain to retire together. They pretty much never go out unless they run out of supplies and then it's usually Ralimanth who whines pathetically and drags his butt into town to get food.
