I have a feeling that Queen isn't taking Sanji seriously yet for some reason, although i think that fight gonna change a lot after Hell Memories.
I just hope some melee fighting and massive scenario destruction, because Zoro vs King is looking better in this matter
Which is weird cuz Sanji's fight always had amazing choreography, like really good shit, i just hope Oda delivers what everyone is expecting.
I think now that Sanji's Exoskeleton is awakened and Sanji destroyed the suit, settling that he will "beat Queen by his own", Oda will go all out with that fight, taking advantage of Sanji's crazy durability to completely showcase and explore Queen's capabilities and how Sanji deals with them (then giving us some crazy melee combat).
That must be the main point of Brachio Snake, an attack that suppose to destroy bones and organs from CoA masters, with Sanji being basically saved by the Exoskeleton awakening.
I can already see Sanji needing to put his arms, legs and neck on time before Queen is approaching him again after hitting Sanji so hard with a punch or a Laser attack that he would break anyones bones, like a Laser Beam Punch with his hand similar to Zephyr vs Kizaru (i want that a lot)
Would be good for Sanji to understand even more how his body works now, and perhaps learn to be more effective with it, coming up with strategies.
But its impossible to ignore that Lunarian thing going on since 1023, specially after King basically uses Devil Leg against Zoro while Queen mentions the Lunarian race and Sanji asks for more info.
