To get extra attack add-ons for Luffy's Gum Gum Scythe attack, you must have over four fruits when using this attack. Once you attack, after your opponent hits the wall press X and you will hit your opponent in the air. Then, keep pressing X. You will do another add-on. You will hit them in the air. Then, keep pressing X. For the final attack add-on, you will hit them up again. Luffy will count down to "1" then he will yell and twist like a spiral, bounce up, and smash your opponent through the roof of the building. If you KO your opponent while doing this trick you will see the building fall around Luffy and he will say, " I'm gonna be King of the Pirates!" and you will win. Note: This trick works well with over four fruits and if your opponent health is down slightly past halfway.
