Wtf are you talking about?
This is a drawing mistake as well:
He didn't have his flip-flops in the manga.
What evidence? There are no panels inbetween indicating his leg switch - you have your "Oda didn't want to draw more panels" conjecture which is absolute batshit. Or "Vergo wanted to troll" which ain't an evidence either.
How can someone have a smug face and yet, write this shit? It's baffling.
Wrong, you don't see anything like that.
First of all, this is a low left angle shot which rather shows you Vergo's left side of his upperbody.
How exactly can you draw a conclusion based on nothing? No, we cannot see a left tilt of his upperbody either, this is ridiculous. Considering the slight low left angle, it would be weird if it's a left tilt of his upper body when it is drawn like that:
His hip has a right tilt judging from the red circle since the red line shows the gaping hole of the labcoat. Vergo most likely rotated his lower body to that point, he wanted to perform a round house kick with his left leg, to hit Sanji with the full momentum of his left leg + body rotation gaining more power.
That's why you mistook the right buttcheek with his left buttcheek since Vergo tilt his hip right to that point in which Vergo's right thigh automatically went along (right), benting his left knee left.
Furthermore, at the bottom corner you can actually see how Vergo's stance truly looks if it's a left tilt with a right kick. Thus, Vergo accordingly rotated his entire body left to give his right leg extra momentum.
In addition,
@Reborn's illustration demonstrates Vergo's left kick once again:
It is the illustration E.
Right leg agenda? What the fuck? Seek help.
Yes, pseudo science because if you had the balls, you would also ask those guys in that science forum whether your theory makes sense or not instead of asking two random guys irl.
So she was just trying to kick as high as possible by benting her knee like that?
I think she might misunderstood the factual situation we're at rn. It is not the point to kick high, it is the point whether she could bent her right leg LIKE Vergo. Can she perform the same if her body is tilted just like Vergo?
In this hypothetical situation, she would have 1.) stopped her momentum with her left leg completely, 2.) switches her stance mid-combat and 3.) weirdly bending her right knee completely right at 90 degrees while managing to hit AND fracture Sanji's shin whose leg matched Vergo's left kicks later without major issues.
Once again, Sanji didn't have enough time and tried to block that kick with his shin at an unconvenient stance. Vergo suddenly switches his leg BUT he exactly aims at Sanji's shin again for... trolling him?
Nobody would even troll someone like that. Hell, Vergo would use that situation to beat Sanji's ass lol.
Not exactly, the kick wasn't still performed like Vergo's.
Your theory is, with reorientation and a proper left tilt, she would have performed the same kick with the same right knee bent but exactly that is questionable itself. Since nobody performed such a retarded kick, it is also hard to reason whether peak human skills in terms of acrobatics would perform the same shit.
The most important question, why this right kick? Why should Vergo weirdly twist his right leg like a monkey and still aim at Sanji's shin for no real purpose? Why didn't he simply kick like your girl or any other human being with decent skills?
I know that base Judge's son is trash but c'mon. He lifts his right leg, sees the incoming attack, Vergo switches his leg but Sanji doesn't do anything to CHANGE his own stance and letting Vergo the opportunity to perform his weird right kick at his shin, especially since Sanji showed the reaction AND combat speed to match Vergo's BLOW FOR BLOW:
Vergo was doing the only inconsistent move with a less dominant stance - which cracked Judge's son's shin - but then consistently tried powerful kicks which Sanji also matched in result. Hence Vergo was actually putting MORE EFFORTS into a weird troll kick than his actual kicks to trash Judge's son? I dunno if that really makes your case better lol.
If you bent your right knee at the opposite direction of what the joint is capable of in terms of motion, it sure wouldn't be that effective lol.
That's my point.
I think only characters like Luffy and Katakuri, benefitting from their DF bodies, are really capable of making such retarded moves effective lol.
Judge's son couldn't match a retarded kick that has no power behind it but instead, he matched proper kicks that have huge power and momentum behind it. Error 404, logic not found.
Nobody denied his flexibility.
However, doing such moves and performing an utterly retarded kick are two different things.
The only low focused stuff about that panel was the drawing mistake of Vergo's left shoe... or Vergo was simply stupid enough to wear his shoes wrong, that's also possible.
I usually do not talk about man's buttcheeks but... here we go:
That ain't the left buttcheek:
That might be a bit unaccurate but judging from the right tilt of his hip, there's no way that his left buttcheek is at that position.
