King and Queen did block Zoro to get to the roof initially; it was Marco that got him through.
And hate what you want; Oda has put Luffy Kid and Law as a trio more so than the five as a quintet. Those three are yet to get their opportunity to showcase their full power. Law has shown nothing new, Luffy hasn’t shown anything too new, and Kid hasn’t shown anything that utilizes the massive pile of junk he picked up earlier this arc.
Oda will probably find a time to showcase those threes powers. And this is how he would.
Gosh... I hate when people use the Sabaody Scene of "Luffy/Kidd/Law" as argument when it literally doesn't mean SHIT...
Let's see.. I will use this:
There was a chapter called "Lone soldier" where both Luffy and Drake oneshot a Number, and Drake declared that he's joining Luffy in this war.... My conclusion is that the two leaders who will beat Yonko are only Luffy and Drake.....
It literally is the SAME LOGIC, that some fans are overusing by selling the whole "3 leaders of next generation" cause they stood together in Saboady....
Cause Law is LITERALLY is Luffy's side kick now... and Kidd is GARBAGE, and I will not stop saying that cause HE IS... and Luffy is ahead of them by light years miles... they never will be more than SIDE KICKS who will watch Luffy/Zoro and SHs do something amazing in front of their eyes and say "WOW, they are SOGEEEE, SO STRONG, I CAN"T BELIEVE IT".... and just support them...
Also, my interpretation for the Sabaody scene was different from you all in that it's not that they will be EQUAL RIVALS in future.... but rather, Oda simply CHOSE them to be in Auction House, and WATCH Luffy punch a celestial Dragon because they are the ONLY 3 D. clan members of Supernova... and nothing really about being equal rivals.... and this is why they were watching a D. like Luffy punch a celestial Dragon, and suprise surprise you all... time passes, and Law is revealed as D.
And suprise surprise.... Kid has King's haki WHICH might give some possibility for Kidd having some D. relations... and surprise surprise... Oda mentions that Kidd's goal is to see the WG and Celestial Dragon system burning as he hates them a lot.... Wow, wink wink...
The idea of interpreting that Sabaody scene is literally so bad as an argument by fans... it's TRASH.... because Luffy/Zoro/Sanji have been a TRIO for SOOOO LONG before even that.... I could even theorize that Kaido will be defeated by Luffy/Zoro/Sanji with your logic guys... and that Sanji will reach the roof later and all other Supernova beside Luffy and Zoro will be down.... but I don't use that logic thankfully
