Snakeman is the application of Kizaru's speed = weight. The faster his punches accelerate the greater the force behind them. Kat was literally getting sent flying by Snakeman punches at first while guarding before he figured Snakeman's trick out.
Never disagreed with this mechanism. You are right about the form using speed to generate force.
Snakeman can and does match Boundman in terms of power when he makes his punches zigzag to accelerate them faster. That is why he doesn't just simply punch straight at his opponent. It also has the added bonus of being ultra fast to the point of even FS users having trouble seeing them coming.
@Bold: based on what?
This is what Boundman's simple Kong Gun did to the same defense which completely blocked Snakeman's Black Mamba.
The portrayal cannot be more clear with Oda even going out of the way to emphasize that even Katakuri's Armament cannot stand upto Boundman. While showing the same Katakuri being able to match Snakeman physically.
I agree about the last part though, speed is it's primary focus and it's hella fast.
Not all G4 punches are equal in power either, Kat also cancelled G4 Boundman's Kong Gun from the side where his donut mochi usually manifests.
As you said, he merely diverted it's trajectory by hitting the Kong Gun from the sides with Power Mochi. Katakuri has never clashed with Boundman in a 1-to-1 duel like he did with G3 (Troll G3, Power Mochi) or with Snakeman (Edged Mochi).
And heck, its arguable that even G3 moves carry more raw power than Snakeman, with G3 clashing with a Power Mochi and Snakeman's attacks clashing with Edged Mochi.
All in all, it is quite clear that Snakeman > Boundman. It being used in the final round against hybrid Kaido proves it.
Nah, Boundman is just flat out better in terms of damage dealt like how Snakeman is flat out better in terms of speed. Luffy didn't use Snakeman once during the Rooftop fight despite using up his all. It being used here does not change 100+ chapters of Boundman being portrayed to have superior AP capabilities. And for all we know, Boundman is probably gonna be used next in the fight against Kaidou.
