Urdim Solanzas Gur Aned, or Urdim Flagcrystals the Bowel of Sports, was an incredibly successful dwarven axeman. He was recognized as a hero in countless lands, and respected in many more; in many places, he was something of a legend. Thirty-six bandits fell to his red steel axe, as well as six night creatures, two Deep Crows, and sixty-nine wild animals. And that's not even counting the ones that were finished off by his companions.
But Urdim's not very interesting. What's interesting is his longest-lived companion, Ontzara Paintpraise. In one of Ontzara's first few battles, her left leg was sliced off at the hip by a bandit axeman. She crawled around for a long time, still gutting people with her spear and never taking a wound, but her luck didn't last forever. Urdim (and I) watched in horror as another bandit's sword arced towards her and cut her right arm off. I was sure she would bleed to death, but she didn't. It was her weapon arm, too, so I figured she would at least die in the next few battles.
Nope. Ontzara got so good at fighting unarmed (ha ha) that she was eventually rechristened a Wrestler. Her specialty was biting: she would crawl up to someone and bite their most vulnerable parts, then shake them around until the flesh ripped apart in her mouth.
Picture, if you will, a woman missing her left leg and right arm, crawling around and biting people in the midst of pitched battles. BITING. This NPC was more hardcore than almost any adventurer I've ever heard of, including all of my own. Urdim might have outlived her, but man, she was so much more badass. Sadly, some asshole shot her with a bow, and she suffocated shortly afterwards.
Dwarf Fortress has never made me quite so sad or quite so angry as I was when that happened. I feel like I should hold a funeral, but I don't know how.
