[@Doc Doctor] You didn't mention the idea of having him in cryo, you didn't state him as pre-war at all. Instead you wrote a character whose main joke is beans, farts, and butts. That's not even really funny, it's stupid and kind of disturbing honestly. 

Oh yes, the giant patriot robot built a by paranoid US government to fight a cold war that has been going for over a hundred years. Yes the setting is designed to show the violence and horror brought by conflict and war. Having two super powers who are almost parodies how truly messed they got is 'humour'. 

As for a side character cross dressing in a cave eating a person, yes, because a stumbling around a corner to find a cannibal in a night dress waiting to jump out and try to cut you up can never be scary it's only funny since 'man is in dress and he eat people'.

As for why raider's can be dangerous, drugged out psychopaths, vicious killers, and worse with nothing to lose but the clothes on their back and a life they care nothing about? Yeah, can't image how easy it would be to deal with them.
