Possibly the most terrifying creature you will find in front of you when looking about an assumed abandoned vault.
Standing at a whopping 18 feet, this Deathclaw was far beyond others of her race. Sentient, smart, scary; the is known to have control enough to not kill everyone in sight, work on arms & armour, and even fix electrical equipment. Often seen roaming the wastes clad in heavily modified set of Tesla power armour, this giant lizard more often then not is hard to fight.
Anyone who dares actually talk to the experimental deathclaw guard will likely find a surprising amount of kindness for a deadly lizard.
