Gruumm has arrived in his ship, the Terror to take over the Earth without interference from S.P.D. Commander Cruger sends Jack, Bridge, and Z on a mission to follow Gruumm through the wormhole. The Dino Rangers go into the woods in search of the Terror. Rather than finding the Terror, they are confronted by Zeltrax and the Tyrannodrones. Jack, Bridge, and Z travel into the wormhole in search of Gruumm. As the Dino Rangers fight Zeltrax, the Terror appears and beam him aboard. Gruumm insists that Zeltrax defeats the Power Rangers, and Zeltrax assures him that it would be his pleasure. Jack, Z, and Bridge reintroduce themselves and inform the Dino Rangers of Gruumm's plans. Meanwhile as the wormhole closes, the other S.P.D. Rangers prepare to join up with the others before the others are trapped in the past. Meanwhile, Tommy appears as the Black Ranger in a battle against Zeltrax. The Dino Rangers teamup with the S.P.D. Rangers to fight Zeltrax, Troobians, and their footsoldiers. Zeltrax leads an army of three monsters that created by Mora, all three levels of Krybots, and the Tyrannodrones. Gruumm and Mora watch as the rest of the S.P.D. Rangers show up and his forces join together against all 12 Rangers. Tommy and Doggie meet for the first time and lead the Rangers against their oponents. Kira, Syd, and Z team up to display girl power while Sam and Trent work together using White Ranger power. Bridge, Ethan, and Sky display teamwork Green/Blue Ranger style as the Black Rangers, Tommy and Cruger, defeat Zeltrax just before he retreats. Jack and Conner both activate their Battlizers to take out Mora's creations. The Power Rangers assemble the Z-Rex Blaster and the Canine Cannon to finish off the footsoldiers. Before the S.P.D.
