Implanters were Yuuzhan Vong creatures that "implanted" surge-coral into sentient beings to make them into slaves. Also known as "creepers", these creatures carried dozens of surge-coral seeds on their backs. The creeper would inflict pain on and disable their victims by using their feathery appendages to disrupt the victim's nervous system. The victim would then be implanted with the seeds. Relatives of implanters were used in the escalation ceremony.
