You're kidding. He has some fast AND powerful attacks like his bair. He also has that delicious chain grab.
For me, I'd say Dedede, Lucas, Ike, and Falco.
Toon Link might get used a lot, and Ike is definitely a popular choice.
That said, these 9 are all potential mains for me:
Bowser
Marth
Ike
Falco
Wolf
King Dedede
Lucario
Diddy Kong
R.O.B.

The letter and number is the track number. I'm disappointed by the lack of FE4 music. Also, Ashnard is a trophy.
