Expect Kidd to beat Beckman to show his growth & actually fight with Shanks this time & maybe impress him enough to not get killed but I can’t really see a scenario where he beats Shanks.
Even if we were to assume Kidd is strong enough to give Shanks are run for his money which is a big if. What he’s doing atm is equivalent to suicide. He’s literally going up against a Yonko, his whole crew + his allies. That’s like Kidd’s crew vs Onigashima & then some. To put things into perspective Law is going up against much less & he’s still gonna be put in a spliff be Teach & his boys
Moreover Shanks is too important & has way too much to offer to the series going forward for him to lose to Kidd. There’s the Red Hair Pirates v the SHs. More insight into Haki, more exposition into his character & his relationship with the Celestials etc. Doesn’t really make sense to me for all that go up in smoke for a bit of Kidd hype which he already has btw.
Honestly I don’t kno what Kidd is thinking, there’s a fine line btw stupidity & bravery & he might end up losing his whole crew as a result of this rash decision.
