Deluxe Beast Machines 
2001 figure:

Beast Changer

Other appearances:   Savage/Noble, or Beast Changer as the toy is called, has never appeared before appeared in the Transformers Universe. He also sets a new first as the only purely organic Transformer.  While the "Beast Wars Mutants" also converted from beast mode to beast mode their story was that they held a robot inside, whereas 'beast Changer is supposed to be a 100% organic individual.  Interesting concept!  What did you think of the idea?
