HEY, i recognize some of those drawings, you traced some of them, get some drawing lessons, no one likes a tracer, just look at mastar media, he traces, and styles greatly differ from Z to Super!, just learn to draw on your own if you want a higher rating from me.
He punched him back to the first sayan form!
Somebody's been watching way to much death battle. The idea that Superman could take anywhere near a serious punch from Goku, even before he goes SSJ is laughable. When he reaches SSJ God, he's literally so powerful that a punch can tear the reality of the universe. Superman has never faced the sort of raw power that Goku exhibits, and there have been plenty of enemies who have hurt him without having nearly the strength of Goku.
You have Perfectly captured both art styles and displayed some amazing lighting and effects that captured both Superman series and DBZ series, Especially the blue-lighting effect on Superman when Goku was charging up. I am not sure if the Goku-power was accurately displayed in relation to Superman as Superman vs. Batman (terrible movie yet relevant) in that Super-Batman vs. Superman Superman was taking some damage which SB would be destroyed vs. even SS3 Goku so Superman's extreme-resilience here I would say is questionable yet still the animation and the art style with a minimal dialogue that captured Superman's antisocial composure was Excellent in this video. Very Cool! also recommend watching another Newgrounds fight video King Kong vs. Godzilla by H-Hakim is one you might enjoy highly as well.
