In Abaranger, this could be Asuka's epic fight against KillerGhost. In Dino Thunder, the episode is for Tommy Oliver, called Fighting Spirit where he fought his past ranger forms in his dream (except Red Turbo) There are some scenes adjusted and reshot in Power Rangers Dino Thunder, to adapt the episode, the remaining rangers lost their powers against the Terrorsaurus V2, the first time Black Ranger got his Super Dino Mode. Overall they are both great. Edit: It's Asuka not Mikoto, sorry.
