How about this
What if the quaza cores that came from certain planets aren't only a special ore
But were created long ago during a war, in which makuhero took part in
maybe once he was an organic lifeform, but rebuilt himself as a robot?
the idea is, if organic life asides from beasts and monsters existed before all these robots, what if they just turned into some kind of crystal (quaza) and their spirits live on inside the heroes?
I dunno, a bit of an absurd theory I guess
and it ties into them actually being more then just robots
I should totally do something related to quaza cores.
