Kyle Zeller is the supervisor of the supersoldiers made by Cybertek for HYDRA. He appeared in "Beginning of the End". He was in control of the first supersoldier and was brought in by the "incentives program". Later in the episode the true nature of the incentives program was revealed, as the wife of Zeller was in fact held captive to force his cooperation. She was a prisoner in the same place as several other inductees' family members, including Ace. Zeller and his wife were rescued and reunited.
