Luffy’s Kong Gatling is Absurdly Strong!

Luffy has been growing absurdly in strength of the entirety of the series, but as of now his Kong Gatling is one of his strongest attacks. After getting one shot by Kaido, Luffy trained in Udon Prison, and became several times more powerful than he was before. More powerful than he was when he beat Katakuri and far more powerful than when he punched Doflamingo.
