When we last left the Power Rangers, an alien armada was heading towards the Earth. Vrak just so happen to be related to the royal armada. Robo Knight had left to charge up. To counter the threat, Gosei gives Troy, Emma, Noah, Jake and Gia the new Legendary Morphers and Ranger Keys. These items allow them to become Super Megaforce Rangers. They also have the added ability to morph into any Power Ranger team from the past. Vrak's brother Prince Vekar leads his group to attack Earth along with X-Borgs and other robots. The Super Megaforce Rangers are equipped with the Legendary Megazord and zords that resemble past team zords.
