Muta-Kar
The name is more of a slang term given to the decendence 
  of the Soldiers who were genetically manipulated due to the Jura/Ertakar war.
  It was a currently acquired name since for a few generations afterwards, all 
  shape shifting abilities of the Soildier's children seemed to vanish, or at 
  least go dorment.
  Quite a few generations later, the ability turned up again, and those born with 
  it could transform easier, and had perfect Jura forms.
  These decendence were given the term Muta-Kar.
  Though, their species is still considered Ertakar.
