User blog comment:DomoGanchan/Luffy will have 6 gears?!/@comment-30109381-20170213143812

Well remember that luffy gets drastically stonger after a short amount of time, so since we are in totta land arc/yonko saga he might be able to defeat big mom in his 4th gear by the time we get there. Or maybe he will develop a 5th and 6th gear by the time we end the totto land arc...
