User blog:DomoGanchan/Luffy will have 6 gears?!

I think I am not the only one who thinks this is the case and if there's already a post about this, I clearly don't have any idea.

So guys. Eversince luffy learned his gears and everytime he uses it, I always think of his changing gears as similar as those found in a manual car. Of course all of us knows that even if luffy has gear 4, it is not enough to beat a yonkou. Right guys? so what if he actually learned two other gears that he hasn't yet shown in both manga and anime? Two gears that could possibly be used against someone in One piece that has a lot more power than luffy. Or maybe even gears that can surpass those super legendary antagonists?

So whadya think guys? Will luffy have two more gears or will he just use a lot of combinations with his haki in those 4 gears he already have to beat the stronger enemies?
