It would be an extreme diff fight.I'm not down playing Kizary,but Luffy is strong enough to tango with and beat top tiers depending on match up.Kizaru skillset is overrated imo.Luffy has dodged those lasers casually since the time skip started.
Nah Luffy needs a buffer before the try top tiers.
he still hasn’t won a fight after any powerup
G4 against Joker he needed the help of the country to protect him was able to escape and go for rnd2 would’ve lost a lot earlier in that fight.
G4 vs Cracker was useless and needed Nami and his appetite carried him 11hrs - had to create a new “full” version to just use Crackers ability against him.
G4 Boundman was utterly useless against Katakuri that he needed Snakeman and that was being outblitzed and outmaneuvered by DonutKata, at best that fight ended in a draw but Katakuri didn’t care to continue the fight. Both winners.
Luffy demolished how many times by Kaido - unlocked Ryou and AdvCoA/CoC was still not enough to really compete with Kaido - needed the help of 4 SN plus Yamato. Lost
Awakening G5 was still not enough for a fresh Kaido who isn’t using part of his energy on moving an entire island while fighting the scabbards, then SN then mink dukes then Liffy then Yamato then Liffy again.
luffy has the plot armor no mi - until he can actually t least beat a YC1 mid/high diffs then he is unable to actually solo a true Top Tier he can compete for a while but he loses high diffs rn
