WSC = World's Strongest Creature
WSC = World's Strongest Clown
Crydo is a fraud WSC, Buggy is the actual WSC.
Buggy Ball > Bolo Breath.
Could Kaido take a sword strike from Mihawk and take no damage? Pfff, even the Scabbards could wound Kaido.
Buggy's offensive firepower and defensive feats far outweigh a former Yonkou like Kaido.
Buggy would never allow himself to be wounded by low-tiers like the Scabbards, as seen by his ability to dodge Zoro in the East Blue, as well as fight Luffy while taking no serious damage, and then dodge Admiral attacks in Marineford.
Luffy became a Yonkou thanks to Buggy's wise guidance, and great pirates like Shanks and Whitebeard were constantly asking Buggy for aid during Marineford. Now, two former Warlords have joined forces with him, showing Buggy's ability to lead through charisma, not force.
Hopefully Akainu and Marine HQ take this threat seriously, and issue a proper bounty of at least 4 billion berry on this menacing, mad, master-planning jester.
