Ranting Llama was from the war-torn country of Peru. Her town was invaded by soldiers when she was a small child. They captured her and made her smack herself and her family while ranting. Then they fired her and left her for dead. Out of nowhere a Llama came in and killed the soldiers by spewing them. After the soldiers, it killed some pregnant women. She tried to stop it but the Llama was unstoppable. The thing was, though... there was no Llama. She was consumed by her ranting. Fighting you cleansed her soul and nose, Snake.
Damn, this is a MUCH better character than those crappy ones they made for the game!
