Oh, this would easily be "Foebane" Oslanag Uzolkobem, or "Foebane Winddaub the Oily Troubles" as mere humans know him. His original first name was Endok.
The most bad-ass dwarf, much less soldier, I've ever had in any fortress. He came with the first wave of immigrants and served for a very brief time as a farmer before goblin troubles necessitated a larger military. His first kill was two years later when he struck down a babysnatcher and saved some dumb kid. Later on, one of the founders, a weaponsmith, was taken by a fey mood and produced Barbfamous the Hardiness of Grasps, an iron battle-axe which had a picture of Endok's slaying of the goblin. It was immediately given to Endok.
Later on, in a great goblin incursion which we weren' prepared for, Endok's lover was killed along with many others. In the ensuing tantrum spiral Endok had to put down quite a few berserk dwarves, being one of the only soldiers who were still hale and hearty. The death of his lover made him grim, and after that point he really cared for nothing but slaughter.
And slaughter, and slaughter, and slaughter some more was what he did to keep his mind of the emptiness of his life. To cut this lengthy story shorter (sorry) he ended up with an artifact shield as well (though not one depicting his exploits) and is, in the 60th year of the fortress, currently a living legend with 349 kills to his name, including all the races - goblins, kobolds, humans, elves, even a dragon. These are all legit military kills, no arena bouts or anything of that sort.
I may have to write up this guy's history in better form... EDIT: too bad his heroically-earned name sounds like a dwarven STD.
