Just because he can't die doesn't mean he can't lose and stuff

he's still very susceptible to being beaten or trapped or something

if he was in a cage he couldn't do anything to get out of it

and he doesn't want to die so he's not gonna kill himself to get out of it

plus he never knows when his task thingy is completed

Also some people seem like they really want Cupcaker to die so I gave him this power so that they can't just kill of my OC and so that if I ever kill him off I can change my mind if I regret it
