Noble

The strange organic monster known as Noble is the only known purely-organic Transformer. He was created as an unintended, unforeseen side effect of Megatron seeking to rid himself of the organic portions of his beast form. Once Megatron's animating spark left the beast it retained life and became a distinct living creature in its own right. Stripped of Megatron's mind however the thing that remained was basically all animal and acted as such. His humanoid form resembles a werewolf, and his alternate mode is a dragon (known as "Savage"). The animalistic Noble formed a close bond with Nightscream akin to that between a boy and his dog.
