Luffy Zoro Kidd Law and Killer all attacked and damaged Kaido in ways that can't be compared to other arc Villains.
the closest thing to what's currently going on is Either Skypiea or Dressrossa. And in both cases Luffy was highlighted as the only effective fighter against the main Villain, while in Wano all Five Supernovas on the roof were established as Effective fighters against Kaido even if Luffy was established as being slight above the rest in G4.
Lol, this isn't true.
Only Zoro and Luffy were highlighted as effective fighters against Kaido. Luffy was never highlighted as more effective than Zoro either.
In fact, that Killer, Law and Kidd lacked the ability to properly damage Kaido was emphasised:
- Kaido previously called Law's Gamma Knife, Kidd's Slam Gibson, and Luffy's Kong Rifle "tricks":
- He called Killer's Scyther Sonic "vexing":
Meanwhile, Zoro's Kokujo Ou Tatsumaki dealing significant damage was emphasised upon:
- Kaido acknowledged that Zoro successfully countered his Tatsumaki:
- Killer expresses surprise that Zoro cut Kaido:
- Mama is surprised at Zoro cutting Kaido:
- This suggests that Zoro's Kokujo Ou Tatsumaki dealt significant damage, as she made no reaction to several other attacks of the Supernova:
- She did not comment that Killer's, Law's, Kidd's or Luffy's other attacks (Kong Gun, Kong Rifle, Rhino Schneider) damaged Kaido.
- Based on Mama's reaction, it should be much more damage than any other attack (with the potential exception of Kong Gatling).
- The only other attack she commented hurt Kaido was Red Roc.
And I should not need to explain that Hiryuu Kaen's attack potency was on another level entirely:
It was so potent that it terrified Big Mom (a top tier swordsman in her own right, and along with Kaido one of the most durable characters in the series). It compelled Big Mom to warn Kaido to dodge:
Just witnessing Zoro prepare the attack had Kaido shook:
After Kaido successfully dodged the attack, Mama chastised him for greatly underestimating Zoro:
The reaction of Big Mom and Kaido to Zoro's attack is truly extraordinary, because this is the first (and only) time Kaido has dodged an attack during the fight.
If any of the Rooftop 5 has been depicted to have offensive prowess that completely outclasses everyone else, it was Zoro's Hiryuu Kaen.
Hiryuu Kaen legit terrified the two most durable characters in the series.
