The biggest question mark about a Gokaiger adaption is whether or not they plan to use non-Power Ranger series from Sentai or not. If they do ... I have no idea. If they don't? Easy.

- "Marvelous" is/was Zordon's apprentice Red Ranger on Altar. Zordon said he was destined for greatness. Zordon relayed a message that the "Greatest Treasure in all the Universe lies on the planet Earth ... seek it out, and nothing will ever stand in the way of good" or something cheesy like that.
- "Marvelous" arrives on Earth (blowing past the Zangyack empire in Episode 1) and lands.

At that point, the rest of the cast (all Earthlings) meet and join up and become Space Pirates or whatever they want to call it with "Marvelous". Guest appearances from previous Power Ranger alumni (a lot of New Zealanders, obviously). The 6th Ranger should be a relative of a former Power Ranger ... like Tommy's nephew or something.

The Ranger Keys aren't just there ... they have to go out and get them. Zeo Ranger powers could be on Triforia where the Gold Power Staff has to activate them. Mighty Morphin powers? Travel to the past where Tommy's Green Ranger clone is (and still has the Dragon coin). Alien Rangers? To Aquatar. Turbo Rangers? Track down Justin (yes, Justin). In Space Rangers? KO-35 it is. Lost Galaxy powers? Mirinoi. Lightspeed Rescue? Track down Carter. Time Force? Silver Guardians and a whole team cameo. Wild Force? Ehhh. Ninja Storm? Good opportunity to bring back Shane, Tori, and Dustin for a fun battle between Alien Rangers and Ninja Storm Rangers. Dino Thunder? It's Tommy time, and just for shits and giggles, his nephew could let him use all his old powers for one hell of a fight. SPD? Doggie and Kat. Mystic Force? Briarwood. Jungle Fury? Ehhh. RPM? Take the subway train in the Samurai/RPM team-up! Samurai? Go visit Jayden and his sister, or whatever.

There done.
