Now, I've posted this in another forum, but I feel like putting it here because it's a good idea, though I'm not motivated to write it.
I have an idea for a Goseiger fanfic based off a fandub of it.
Pretty much it takes place in the future, where the video game industry died because of the over abundance of cutthroat tactics that treated the customer more like a criminal than an actual customer. Things such as day-1 DLC ala Mass Effect 3, Disk-locked Content ala Street Fighter x Tekken, having to stay online to play the game ala Diablo 3 etc, and one of the games that killed the industry was a game called Planet Guardians that employed a tactic where it would be incomplete and you needed to download some DLC (and pay more money) to complete the game. When the industry died, the company who made the game, Tensou Gosei, shut down, never releasing the final packs to the game.
Five kids enter a game shop that is going out of business, and they come across a scientist who is trying to reboot the video game industry via virtual reality. He asked the kids to volunteer and they all agree for unique reasons (one is bored out of their minds, another just wants to look out for his sister, etc.) and they all get hooked up into a machine. The scientist then loads up Planet Guardians, but then something bugs up and it traps the kids inside the game. And now they must try to beat the game... Yes, they must complete the game that was never complete. However, the game thinks they are characters in the game (represented by a floating head), and appropriates them with the technology to become the Planet Guardians, though one of them just decides it would be better if they called themselves the Power Rangers. And so, Power Rangers: Planet Guardians begins.
Naturally, this leads to an interesting situation. Much like in Goseiger, the Power Rangers unlock a bunch of the Headders early on (due to the fact that said headders are Day-one DLC) and they beat Warstar. The game isn't over however, as it then sends the incomplete data at them, which are the Yuumajuu (or as I'll call them, Goylegars). However, there's also a piece of incomplete data that was supposed to be a super secret unlockable character, but due to the fact that he's incomplete, he bugs out and attacks the rangers early on, as well as have all their powers. Bladerun's also reinterpreted, as he too glitches out and becomes a Goylegar as well, despite the fact that he was supposed to be a villain for Warstar. He then becomes aware that he's in a video game and seeks to get into the real world...
Some time near the end, pirates hack into the game, and show that they mean business by hacking the game so that they would become other Power Rangers and seal the Planet Knight (Goseiknight) into data in the shape of a key. They also infect the game with a virus, and so the representative of the game, the giant head, becomes distorted. Anyone who's seen Go-Busters would see where this is going.
And so now the Rangers must not only defeat the Pirates, but also an aware Bladerun who, throughout the course of the series, learned how to mod the game and created his own
faction: Matrintis. Not only that, but they also must try to debrainwash the corrupted game, who now calls himself "Messiah".
