Its funny how self proclaimed "analysts" of this manga seem to miss key factors as to what the Robot's role actually can be when it singlehandedly almost destroyed Mariejoa 200 years prior and is powered by Luffy's heartbeat.
"Analysts": Itll only be used to help them escape, not fight. Not target the one thing it may have been targeting over 200 years ago at Mariejoa: A Gorosei.
Oh, and lets not forget that Luffy is the only person who has touched Kizaru in 20 chapters, while everyone and their mother has attacked Saturn to keep him at bay. But nope, Robot powered by Gear 5 cant or wont do anything to stall or hold him back while everyone else has.
Lets ALSO not forget that for like the nth time in this series, one of Luffy's direct fights has ended in a situation where the antagonist is STILL A THREAT while he's at a disadvantage. Lets go down the list shall we?
- Arlong: Put him underwater
- Mr. 3: Ran Away
- Wapol: Ran Away
- Crocodile: Beat him 2 times on separate occasions
- Enel: Knocked him off the ship for Skypieas destruction
- Lucci: Ran out of Gear 3 and had to hide
- Moria: Ran away from Luffy and made him lost
- Hody: Ran away from Luffy to attack Shirahoshi
- Caesar: Ran away from Luffy for Shi no Kuni
- Doflamingo: Kicked him out of the castle for Bird Cage, sicced a controlled Bellamy on him, Gear 4 time limit for 10 minutes while everyone else saved him
- Katakuri: Ran away from him due to Gear 4 time limit.
- Kaido: Defeats Luffy 3 separate times, 4 if you count his G4 time limit in 1003. 1 of which is a food recovery instance after 1011 to 1025.
- Kizaru: Hits Kizaru, yet Kizaru is up first while Luffy is in a food recovery period from 1093-present time.
Are we expecting Luffy to face Saturn and go through this phase yet again, while Kizaru is still up playing the EXACT role other antagonists have played in stalling fights literally every single arc since Arlong?
Realize we are now in extremely dangerous territory where anyone not named Luffy Is likely NOT going to be front and center this arc once again. If the VAs do not serve as a means for anyone to fight anyone, then there is no feasible way Zoro gets a fight without Sanji and vice versa in the same arc.
So yes, when I say the Robot will come in and help Luffy, I absolutely mean that Luffy will VERY likely either continue to fight Kizaru while the Robot stalls the Gorosei, or they will fight both Admiral and Gorosei together. I have not discounted Saturn's antagonism ever, I just simply think that he's not the main focus of this arc's main battle with Luffy
