Re: GEAR 4
Here's an interesting thought: Everybody assumes that since luffy came out with Gear Second and than third; the next thing he'd do is a gear forth. Here's my question: Why not a Gear First.
Every person who's seen Gear Second and says Luffy went up to a higher gear is just being presumptuous. Luffy's never defined his regular state as gear anything. The whole terminology with the word gear makes us think about cars and shifting gears. Two things that seem to have notiong to do with Luffy's gears( w/ the exception of gaining power). In cars you shift Gears to lower your RPMs, decreases the stain on your engine and it increase Torque to the wheels. Also when you shift you go from 1st gear than 2 and than 3 and to however many gears you have. They go in order...unlike Luffy who just activates them whenever.
Also, in the way he says the name "Gear second" instead of "Second Gear". Very Uncarlike
So I think, Instead of a gear 4 Luffy introduces a lamer- less powerfull Gear First. And the power it gives him is a way to "Shift" through gears, like maybe a way luffy could take in air and store it. So that he can go from Gear first into second than third. Like he'd use the super speed bonus from Second to get right behind somebody and before they'd even seen Luffy he'd shift to third a put a Gigant pistol into the small of someone's back.
I think it'd work, Gear second uses his Legs as pumps, so, there should be a way for him to uses that to pump air directly into his bones.
Well it's either how I've said it or he'll just use 2 n 3 at the same time... It sould work as long as he doesn't make ethier of his legs giant. (He wouldn't be able to pump with them like that)
P.S. If he could make two limbs large at the same time (instead of just the 1)... Gigant Gear second! (with 2 giant legs as the pumps)
