Fast travelled to the BADTFL building. As the scene came out of the loadup blankness, I was just across the street from three raiders fighting a deathclaw in broad daylight. After a moment's assessment, I lobbed a grenade in the middle of the furball and me and MacCready started firing away at it. The deathclaw felt our shots and turned towards us to get ready to charge us, but just then one of the raiders must have hit it pretty solid and grabbed its attention back, because it turned around on them again and grabbed the closest one. Then the 'whoa' moment happened- instead of the usual swat/splat/dead thing they do to mere mortal men, this time it picked up the raider in both 'hands', lifted him into the air and shoved him up against a pillar, grunted for a moment, then pulled him apart in a bloody spray. Just... ripped him apart like somebody tearing a tomato in half with both hands. If your hands had 9-inch tyrannosaurus claws on them. After the battle ended (we won), I went over and checked out the remains of that raider- there wasn't a part left attached to another. Even the torso was gibbed into little chunks. Looked like the tomato had been hurled thru a chicken-wire fence.
Glad I'm not a melee build.
