Sanji was able to defeat Yonko Kaido’s second strongest Commander.
In his fight with Queen, Sanji awakened the same genetic enhancements as his siblings, gaining an Exoskeleton and superhuman physical constitution, including accelerated healing.
Sanji has become fast enough to the point where he seemed to vanish right in front of Queen right before attacking him and can seemingly turn invisible without his Raid Suit. As his enhancements were complete, Sanji has shown far greater power in his fighting style, able to knock down Queen with immense power and develops fighting techniques that would have been physically impossible for him to do before.
During the Wano Country Arc, Sanji revealed Ifrit Jambe, a new enhanced version of Diable Jambe. It is the result from the awakening of his genetic enhancements combined with his trained Busoshoku Haki increasing his leg’s strength and endurance. With this new technique, Sanji’s legs can withstand much hotter temperature and are thus capable of generating much stronger flames, a feat he would have been unable to achieve without his newfound powers.
Zoro unleashed Conqueror’s Haki. He strengthened his “Kyutoryu: Asura” using Armament and Conqueror’s Haki, which allowed him to leave a permanent scar on the “Strongest Creature” Kaido in his hybrid-dragon form.
Zoro was able to defeat Yonko Kaido’s 1st Commander King.
He awakened Conqueror’s Haki, was immediately able to use it to coat his attacks, figured out King’s power, and defeated him in three blows.
This raid will not be Marineford 2.0. That’s what has been in the works in the background this whole time with the Reverie incident, the Revolutionary Army, the World Government’s new weapon, Blackbeard on the move, Shanks as well.
“We split up and trained all over the world for this”
“You’re pitting yourselves against the new generation now”
This is what it’s about. Our crew showing they belong here, Whole Cake Island ended with Morgans declaring Luffy the 5th Emperor which was met mainly by skepticism and rage from three of the others. This raid is a showcase of our crew and how they have grown, not Marineford where our captain was nothing but an ant among monsters.
