Rawr 住在黄杨木旅馆屋顶附近有片水洼，旁边那个伸手不见五指的的一个洞穴里。Entering the cave triggers a cave-in which will draw Rawr's attention, resulting in it starting a battle with the Courier. The Courier will be trapped in the cave until the second warhead, which will fall with the rubble, is detonated. 它有着令人难以置信的速度和强悍之极的力量，加上它那双毁灭性的爪子，足以把任何胆敢闯进它地盘的家伙撕成碎片。它的众多受害者中有一个叫Gleeson的NCR士兵。在被彻底撕碎前，他在绝望中发出了一段求救信号。根据这段信息显示，即使强悍如Rawr，它也有着和其他死亡爪一样的弱点：害怕信号枪的火光。这可能是Rawr唯一的弱点。
- If one switches to third-person view, they may be able to see the body of a deathclaw inside the cave behind the rock wall to the Courier's left. It is not alive and does not register on the Courier's compass. As soon as the cave is entered far enough, that body vanishes and Rawr appears a short distance deeper into the cavern.
- Rawr's strength allows him to kill a power armor wearing Courier with maximum Endurance in three strikes at level 25.
- Occasionally, when sneaking slowly into the cave, the explosion will go off, and Rawr will spawn hostile to the Courier, but will not charge in to attack. Even when Rawr is fired upon and damaged, it will still stay still, as long as the Courier continues to sneak and stays out of Rawr's Perception field.
- Rawr cannot be knocked down by normal means. If the Ranger Takedown is used on him, it will simply be staggered. It can be knocked down with a critical hit from an anti-materiel rifle with explosive rounds.
- Like all abominations, Rawr is afraid of flash bangs and the flare gun.
"Rawr" is an internet slang for a roar, specifically that of a dinosaur or cat.
