Huh, TIL.
Gurren Lagaan is surprisingly meta. One of the big problems with the fight-focused anime formula is that they constantly one-up themselves, eventually power spiraling to unsustainable levels. So Gurren Lagaan's plot revolves around an energy literally called "spiral power" and how unsustainable it is.
