Suddenly the doors were pushed open and a man in Legion armor covered by an NCR Ranger duster coat was standing in the doorway. He marched up to the group of wastelanders and sized them all up before saying, "Alright, I don't care who is what or where you're from, if any of you let your feelings about each other get in the way here I'll kill you myself."
Then he walked over to where the ammo and weapons were and picked up a shiny new Ballistic Fist. He inspected it quickly then put it on his left hand. Everyone noticed that he had a much less-new one on his right hand as well. He held his arms out and flexed his fingers in the gloves before nodding approvingly then picked up a handful of shotgun shells for the hunting shotgun on his back before turning to the rest of the group again.
"I am Centurion Marcus Bernicus, though a few of you here might know me better as Marcus the Anvil Slayer."
A few NCR soldiers and a fellow Legionnaire perked up thier heads at this, as he knew they would. The story of his victory had spread among many people who's business was war, even among the ranks of the Legion's enemies. He took pride in this, and used it just as any other weapon he had.
