Wow, I remember reading a very long, detailed theory on gear fourth like 6 years ago and its pretty scary how close this is to what I read. The guy had drawn out examples and everything, the theory was that Luffy was going to be able to control every single muscle of his rubber body allowing him to no longer even throw his arm physically to hit someone, he can just hold his arm out and it'll shoot out. Luffys arm turning in mid air almost seems to be that, King Kong Gun was his arm contracting inwards but Serpent shows the greater control I mentioned. At first I thought he was just mimicking Sengokus Buddha form but this is certainly something I need to see more of to understand, he's bouncing around like a ball all while in haki? If his muscles are full of air now, does that mean his bones are normal sized? Or is this just a condensed form of gear 3rd
Also, I'm hoping that Gear 4th is not used nearly as commonly as 2 and 3. I feel like this will be the case… Just a gut feeling there. If it's used too frequently, it'll become associated with Luffy's identity, and to be quite frank I don't want that lol. I feel like this Gear should be used on special occasions. I want to see this version of Luffy, in fights, maybe 20% of the time. Not because I don't like it, it is just very jarring.
I agree, I was gonna compare this to monster chopper but since he can control that now than I don't know what else to compare to, this is not a powerup I want to see used everytime without truly being needed. Has Luffy used gear 2 combined with gear 3rd outside Moriah? I can't seem to remember.
