One Piece Grand Battle Unlockables:

If Sanji is fighting Nami or Miss Sunday (or it may just be Nami) if you perform his secret attack he says different stuff, and in the end, his eyes become hearts (if you kill them with the secret attack, the complete one, in the end he'll go "I wish we could've spent more time together," while hearts are floating around him.)

To get extra attack add-ons for Luffy's Gum Gum Scythe Attack, when you use this attack you must have over four fruits. Then, when you attack, after your opponent hits the wall, press circle and you will hit your opponent in the air. Then keep pressing circle. Then you will do another add-on. You will hit them in the air. Then keep pressing circle. Then for the final attack add-on, you will hit them up again again Luffy will count down, 3 2 1. then he will yell and twist like a spiral and bounce up and smash your opponent throught the roof of the building. If you KO your opponent 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 a little bit past halfway.
