Okay. I admit, it's awesome.

I believe that is actually from the final fight of the series
Either that or the scene where Simon turns the moon into the flagship

***** that punch is only 1/3 of the way into the series.

Actually, the punch that that is modeled after is the kne during the fight with anti-spiral, just before they clash gigadrills.
