Ryker Zune

Ryker Zune was the nephew of Dr. Haverson. Ryker was interested in the Bio-Power of the Bionic Rangers and secretly took a prototype Morpher from his uncle's lab. Ryker altered the Morpher into his Retro Morpher and linked it to the Morphers of the other Rangers to siphon off their excess energy. When the Morpher was fully charged, Ryker was able to morph into the Black Ranger. However, since his Morpher had a limited power supply, he was only able to be a Ranger for short periods of time. Initially, Ryker kept his identity a secret, but when he was injured in a fight, Black Ranger used up all his powers and demorphed in front of the other Rangers. While at first, Dr. Haverson was angry that Ryker stole form him and was siphoning power from the other Rangers, eventually Ryker was able to win the trust of the Rangers and his uncle, and their alien ally Goldex fully charged his Morpher with Bio-Power and even gave Ryker his own Zord.
