Fanfic Ideas You're Sure Only You Think Are Good

Just had a weird idea for a massive Super Robot crossover.

Basically, a world where all Super Robots are sentient Mechanical Lifeforms with their own personalities (which may or may not be based off that of their pilots).

They still fight many of the enemies (other robots, monsters and kaiju, etc) that they fight in their series, but now they do it themselves without human pilots, while having their own society.

Thinking of using some of the big guys for this one: Mazinger Z and it's various sequels and Spin-offs, Getter Robo as well, Tengen Toppa Gurren Lagann, Kotetsu Jeeg and it's sequel, Kotetsushin Jeeg, and Godannar as well (which I re-watched some episodes of, inspiring me to toss out this idea).

As for why this happened, I could go with it just is, deal with it, Getter Rays, Spiral Energy, G-Stones (which did create the Super AI Braves in Gaogaigar) or all of the above.

Haven't decided yet.

.....you know what I need to do? Watch Bravern, and add that in. Why ain't I watching that series yet?

So yeah. This is another fanfic idea I'm sure only I think is good.

Splatoon and Persona crossover where literally everything that happens is the exact same as it goes in the Sploon universe, and all the Persona characters are just Inklings or Octolings and the only difference is that everyone has the potential of a Persona.
