Karra

Karra was a Cheetah Person who originally had a human or near-human form.

Biography
Karra first appeared to Ace mounted on a horse in a playground in Ace's home town of Perivale. She transported Ace to the Cheetah World and there killed Stuart, also abducted from Perivale. Ace threw a rock at Karra's head, hurting her, though she soon healed, thanks to the power of the planet. Respecting Ace now, Karra introduced herself and offered Ace a new life with the Cheetah People, a prospect which tempted her.

Karra returned to Perivale, scared off the Master's minions there and readied to attack him. He stabbed her with a knife. She reverted to her old form for a few moments before dying. A Cheetah Person appeared to bear her body away. (DW: Survival)
