Wario's is where he turns into Wario-man and Strength, speed, and agility is increased, it seems bad, but from the video it seemed effective, we'll seen soon enough.
Although many thought that he would have his super fart mushroom cloud from the E3 06 video as his FS, but he didn't, even I was suprised.
I love Link's, Lucario's, Samus's, and Pokemon Trainer's...so damn powerful.
oh, and of course, Marth's...captures all the joy of getting a critical hit in a Fire Emblem game. I hated Ike's because it seems everything about him is aether, even a victory pose...that just sux.
