Mawdryn
Mawdryn was the leader of a group of scientists that attempted to discover the Time Lord’s secret of regeneration. Due to his experimentation, he was cursed with unwilling eternal regeneration.
Mawdryn and his followers stole a metamorphic symbiosis regenerator that they used on themselves. Due to this machine, their immortality was one of unending mutations and regeneration. They were exiled from their world and their spaceship entered a warp elipse.
