I would suggest killing blow.
You are getting in of course.
Second surly not an entire mountain? Because that would be one strong ass ogre.
Well my Maneater is called Bullgruf Stonesmasher
Backstory: Bullgruf was, (and still is) a rough child. He wanted to be a Stonehorn when he grew up. When he went to play with other little guts, they all bruised easily and excluded him for being so rough. Eventually, Bullgruf found a stonehorn slamming a mountain, and challenged the stonehorn. He began punching the mountain, until the mountain broke and Bullgruf stood tall above the rubble. The Stonehorn admired his primitive strenght and followed him wherever he went. He was named "Ruckus" or "Rok".
Bullgruf ventured far and wide, making a living as a sell sword. He helped his fellow bellies in the North. Took part in an Impiral excursion in Lustria. Cleared the sewers of the skaven plague single handedly in Bretonnia. But his greatest feat was helping the dwarves.
The dwarf lord Vilgromaar had warred with the Orc Warboss Gut-Rippa for many years. The Orcs led a massive attack on his stronghold and Bullgruf was hired. As the Orcs approached, Bullgruf and Ruckus destroyed mountains and cliffs, crushing every single green-skin for miles. Vilgromaar was so pleased that he forged a dwarven warhammer and gromril armour for him and Ruckus.
Bullgruf now has heard the call of Gantherogue, and is awaiting his reply. ;-)
Favourite Food: Anything really. Even rocks are enjoyable by Bullgruf.
Weapon of choice: If he's not pummeling something to mush with his fists, then he's using his special warhammer.
Armour: Gromril armour fitted to his size.
Skills: Immune to psychology. ( I'm not sure about the second one. Maybe something with the same rules as poison to symbolise his crushing blows?
Really hope you pick me and Bullgruf, of course the Stonehorn is for fluff and if you don't ewant him than he won't take him but if you do, well here you go!
