The original Megna Defender arrived on the scene to save Leo from an explosion. Despite his heroism the Defender acted very coldy to the Rangers. All he cared about was destorying Scorpious and finding the Lights of Orion. Scorpious had killed the Defender's son (Zika) in an invasion of the hero's home planet. Megna Defender later was banished to a crevice by Treateron. The Megna Defender vowed revenge for the death of his son and planned to use the power of the Lights of Orion ( a power he once hid from evil) against Scorpious. The power did not go to him however and went to the Rangers instead. Megna Defender was reckless and even risked hurting innocent people to achieve his goals. Mike's soul wieghed heavily on his conscience. Leo tried to find the good in the Megna Defender. Megna Defender revealed that Mike had fallen into his crevice. He saved Mike and used his life Force to restore himself to full health. Megna Defender created a disturbance in Terra Ventue that threatened to destory the colony. Megna Defender was also badly injured. He soon appeared to him once again . The young spirit enouraged his father to be a hero once more. Megna Defender released Mike and used all his remaining power to stop the disturbance, resulting in his own death. Later Megna Defender came back as a spirit and gave his powers to Mike. When Mike successfully used his powers to free the slaves of Captian Mutiney, Megna Defender's spirit thanked Mike for using his power well ( Mike lost the powers during the rescue).
