Bastard

Bastard is the name of the wolf pup given to Rachel Lindt by The Siberian during the introduction of the Slaughterhouse Nine Arc.

Personality
Bastard is a pure wolf who lacks the inherited domestication of other dog breeds. Rachel was worried about training him.

Relationships
Eventually became Bitch's favored "dog".

Appearance and Powers
As a small puppy he is considered adorable by most humans ignorant of what he can do.

He is more responsive to her powers than her usual dogs, his bone and muscle growth more symmetrical and less grotesque. However this also makes it neigh impossible to ride him.

Background
Taken by the Siberian. It remains unknown where he came from, though Rachel belives it was from a wild wolf pack.

Post-Leviathan
The Siberian gave Bastard to Bitch. Nipped her the first time she touched him, earning him his name.

Post-Slaughterhouse Nine
Able to grow to roughly five times his normal size. "He’d grown rapidly in the past few weeks, but it still meant he was small". Was used in the fights against Dragon's suits.

Post-Echidna
Came to the Behemoth fight.

Post-Timeskip
Grew into full size and was fully trained.

Gold Morning
Survived and was used in several crucial moments.
