The epic space battles in Gurren Lagann's time skip, where Dai Gurren Dan's crew is dropping like flies.
"Libera Me From Hell" swelling in the background as they go screaming defiance into the very face of their Doom, curling a fist to give one more serving of bloodied knuckles to its face.
ROW ROW, FIGHT THE POWAH!!
The end of the this epic amv
on amv.org still makes me tear up every-time with those scenes.
Dragon force + Gurren Lagann = awesome
