Power rangers: Super Legends

Long thought to have been purified by Zordon's energy wave at the end of Power Rangers in Space, Lord Zedd has reappeared in his old form. Concealed in a hidden dimension, he is interfering with the time stream, trying to alter the course of history to destroy every Power Ranger throughout time. Operating from the Hall of Legends, the new/Future Omega Ranger (confused with the original one and himself) must gather a force of Power Rangers and artifacts from across time to break through into Zedd's hidden dimension and restore the timeline.
