He could also have used far more and more varied techniques than creating biscuit soldiers, and produced more varieties of biscuit constructs and soldiers.
It seems like he actually did it.
We can see the ground was in biscuit, we see a wall in biscuit, seems like Cracker manipulate the entire enviroment, in the past we believe these things been signs of him using awakening since they are similar to what Doffy used with his awakening:
The problem with the Cracker fight, it got cut of in the moment when things became very exicting, when Cracker fought Luffy in Boundman, we didn´t see the clash but it seems like Cracker was dealing with him in a close combat battle. And it make sense if Luffy used G4 multiple times against Cracker.
It is kinda sad, the anime did him justice however I would love to see him in the manga fighting Boundman.
Alone his anime portrayal was looking dope, he legit made Boundman looking like a fodder, a reason why many people placed him over Doflamingo due the direct comparison to Boundman battle.
Cracker fought Luffy, Nami(literally his df weakeness) and homie forest.. And losed in the end after a 11h battle, which Nami even state that Luffy literally risked his life to win that battle.
Without Nami and the forest, Luffy would clearly lose that battle.
And against Katakuri without plot, Luffy would lose the first round if Katakuri used his Mogura rather his mochi to kill Luffy, I mean Luffy couldn´t move anymore, Katakuri could legit finish him off and kill him with mogura.
It was clear that Luffy without FS wasn´t YC lvl3, he was close to that lvl but he would lose to anyone one that lvl in a 1on1 fight.
A reason why I still think that Doflamingo wasn´t stronger then Cracker and let alone Katakuri.
(Without plot Katakuri would legit low diff Luffy, alone in this scene he could kill him pretty easily, characters like Katakuri and King are leagues above Doflamingo).
