History
The dog that would be known as "The Beast" was born from the Inhumans' experimentation on canines, her mother had been brought to Attilan as a puppy and experimented on by the Surgeon Supreme. She was impregnated by her own cloned genetic material and gestated 5 puppies with the purpose of performing terrigenesis in the womb. Lockjaw was successfully mutated, while his siblings were not, and before the Surgeon could remove them from the womb for further experimentation he teleported his siblings to four different locations. The Beast was teleported to the Savage Land where she was found and adopted by a pack of Dire Wolves, eventually becoming their pack leader.[2][1]
Attributes
Powers
Extended Longevity While The Beast apparently did not gain the same powers as her brother, her exposure to Terrigen did give her a much longer lifespan than the average dog, being already thirty years old when she first appears.[3]
