Although brief, Luffy and Shiki's mid-air fight is awesome!
Luffy's final attack of the movie, Gigant Thor Axe, which is basically him using Gear Third to inflate his foot and putting it in a thunderstorm. (It doesn't hurt him because he's rubber, which is an insulator). And then bringing his giant, lightning charged foot down on the enemy. Watch for yourself.
Zoro beating Dr.Indigo. Lampshaded by Chopper and Usopp.
