I am not here saying Kidd is the weakest SN. Just that he us so far out of luffy's league I dont see how he could ever be luffy's wb.... ever.
Also I dont think you want to go down the road of comparing SN. Like I said urgue beat a commander, law would of beat anyone other then DD with that Gemma knife, so assuming dd is commander level that makes two sn who succeeded where Kidd couldn't, also I should point out bonney isnt in the conversation because her fight was pre timeskip.
As for bege..... dude... bege did 10x better then Kidd did. Kidd had an emperor fall into his lap, at his home base. Maybe apoo instantly betrayed him who knows(we know apoo was working for kiadou, but bege was in the literal center of an emperor's land. Bege had the entire force of an emperor in front of him. Ya he had a few more allies then Kidd but he also had... an entire emperor's army in front of him compared to Kidd who had just one emperor to deal with and maybe a trader.
The difference is bege made it out alive and he had time to screw around and try to save the sh crew and distract BM with a cake for some reason. Kidd couldn't make it out. Kidd had nearly every single advantage you can reasonably have to try and escape from an emperor and he couldn't make it out.
But regardless you got me side tracked.
The point is compared to luffy kidd is a disappointment. He has no feats what so ever to put him in league with luffy. Hell law and urgue have more feats to be arguably luffy's equal then kidd does.
Oh and if we forget luffy level feats, the only feat at all Kidd has post time skip is sinking 2 bm ships. Sadly carrot just showed us how easily that is...... a man that can control metal was upstaged by a bunny.
The ONLY way you could say kidd is anywhere near luffy is by saying he was portrayed that way. And that is a horrible arguement. That is like saying crocodile is luffy level because he was portrayed that way in ID.
And the reason portralay is a horrible arguement is oda has dropped that portrayal. Ya luffy and him can both carry large stones... but urgue was the one who best snacks. Urgue.... why? Oda could of just as well made that Kidd who beat snacks and then you would have a leg go stand on and defend kidd with. Oda could of had kidd beat jack (literally everyone has beaten jack at this point) but no he didnt. Oda could of had kidd beat someone on the shanks crew... didnt do that...
You know what oda did do? Instesd of hyping Kidd up. The 1st thing he tells us about kidd is from carbiou "he has a bad reputation. He lost to shanks then lost to bm"
Great.... good job there hyping a character who is supposed to be a big deal... telling us about his failures. And those failures are now made worse because now us fans know why kidd wanted an alliance to fight shanks, because he couldn't get revenge on his own...
Oh that's weird... shanks Beckman and yassop all use metal weapons. Roo also used a pistol. Maybe kidd will become a big deal by killing shanks while luffy beats bb. Then he would finally be on luffy's level.
We legit have no idea if Law is able to beat any of the Yonko or Yonko commanders with Gamma Knife. Luffy had a poison hook go straight through him and water healed him all the way back in Alabasta so even if Law hit someone with it it's not an auto win. Bege was running away from Big Mom when he was not her main target and he didn't have just a few allies he had all of Germa, the Sun Pirates, and Luffy which compared to Killer and unnamed fodder is not comparable. I never got the vibe that Kidd was suppose to WB that always seemed more like Law's future with Kidd more than likely being the Shiki of the three of them.
As far as feats you are right Kidd does not really have any, but I'm not downgrading him for at some unspecified point in time losing to one of Shank's crew (this could have literally happened three months into the timeskip we don't know anything about the incident). I also am not going to downgrade him for not wanting to waste time fighting Big Mom if his target his Shanks. Zoro was against attacking Big Mom when their target is Kaido only Luffy would challenge two emperors at once its not the norm. I would just rather wait and see before deciding that Kidd isn't on Luffy's level.
