A fisherdwarf was doing his thing by the stream when his fishing caught the attention of an alligator. It scared him away from his catch, but then he got pissed and ran after the thing, crossing the stream and attacking it with his bare hands. I feared the worst, but he was actually dodging all of the attacks and doing some real damage.
I ordered my squad of 10 wrestlers to assist, but they couldn't figure out how to cross the stream. I ordered a bridge be built, but that would take time. The fisherdwarf, meanwhile, had taken a couple minor injuries but had beaten the gator unconscious and was wailing on it's head. He kept it up until he over exerted himself and passed out. He came to, saw the gator, and resumed his rage beating until he passed out again.
His third round of beating was the gator wake up and start fighting back. The dwarf was exhausted at this point, and could not dodge as well. This resulted in both his hands being bitten off in rapid succession. This freaked him out, but he started kicking and biting the thing until it was knocked out again. He grew pale, but continued biting it in the head, over and over again. Eventually, the gator succumbed to his wounds and the dwarf survived.
The bridge was finished and he waltzed his way into the hospital, had a couple bite wounds scrubbed with soap, and went on his merry way. I liked his fighting spirit, so I recruited him into the military. He will get some proper armor, assuming I ever manage to find a unit of metallic ore.
