My player's fighter in LotFP started out as a no-nonsense bandit. He quickly gained fame by beating the shit out of any noble asshole in a shining armor he could find. At level 5, he had killed a demon, the black knight, a goat-demon, a succubus and a whole lot of people called the best at fighting by their peers. He had also acquired a badass magical sword, a shiny armor and a fucking lot of cash.
It is probably important to also note that during his adventures, he was almost always in the company of a mud cleric who was the unluckiest man alive, but still managed to stay alive, probably due to his God being nice. The session before our last, said Cleric decided to retire to raise an orphan as another cleric, because he was, well, one-eyed, one-handed, didn't have feet anymore and had a punctured lung and stomach, and still survived.
So yeah, badass fighter goes to another town 15 days from here with his buddies. They meet a bunch of bandits, no-nonsense bandits that merely take hostage one of their (trusted and old) follower and ask for all their stuff. The fighter, his dwarf companion just go "fuck you you stupid bandit, we rule", and eventually let the new follower realise they don't give two shits about NPCs, so he rolls for morale and fails, and quits their side. So they both charge. That's ten bandits, most of them with bows. They actually managed to kill every single one, short of two. In the end, there was two bandits left, with daggers, and the dwarf and the fighter, bare-handed and with 2 hp out of 25/27 left. The bloody melee draws longer until the bandits get hurt but don't go down to 0. One last morale rolls tell me they're gone berserk.
And then they both crit their respective PC opponent, put them at -4 each, that's instant death in LotFP.
They loved this final campaign-stopping TPK.
