Robo Knight

Robo Knight is a mysterious robotic knight who was created by Gosei centuries ago for the sole purpose of protecting the Earth's environment. He first briefly appears in Troy's dream of the Legendary Battle, and later makes his debut in the episode "Robo Knight". It is revealed that after being dormant for so long he has lost some of his memory, including the one where Gosei created him. When the Toxic Mutants emerge, Robo Knight aids the Rangers but then leaves. At first fighting without thinking about human sacrifices and leaving the saving to the Mega Rangers, their influence gradually changes him. Robo Knight then spends the rest of the first season trying to understand human nature. Robo Knight has the ability to turn into the Lion Zord which can combine with a dump truck to become the Lion MechaZord and joins with the Knight Brothers (consisting of the Sky Lion Zord and the Sea Lion Zord) to form the Gosei Grand Megazord. In the finale of Megaforce titled "End Game", Robo Knight sacrifices the bulk of his energy to restore the Rangers' Morphers. He disappears as the Armada's invasion begins; and Troy starts to look for Robo Knight's current whereabouts. Troy has a feeling that the Rangers will meet Robo Knight again someday, since his dreams foretell Robo Knight joining them in the fight against the Armada. Robo Knight resurfaces in "Vrak Is Back, Part 1", where it is revealed that his body was found by Vrak. Vrak reprograms Robo Knight to serve him and orders him to steal the Sixth Ranger power from Orion and corrupt it. In "Vrak Is Back, Part 2", a powerful blow from Troy brings Robo Knight back to senses. Robo Knight returns to Vrak's underwater lair to free Orion. There, he sacrifices himself to save the life of his fellow Sixth Ranger by giving him the last of his lifeforce. Robo Knight is voiced by Chris Auer in the TV series and by Richard Epcar in the video game adaption.
