[u]For the Wii U[/u]
Fox is my main for 1 v 1 matches. Good speed though he lacks a good way to K.O people other than his up-smash and up-air.
Great at racking up damage, but his attacks and rolls are sometimes too short distance wise. Still a force to be reckoned with.
Bowser is my alternate (which is shocking since I use a fast then a slow character). If you've ever fought a good aggressive Bowser player........it's just terrifying. You can't get away from him!
[u]For Melee[/u]
All about Captain Falcon. All his air moves have knockback and he is crazy fast. I love spiking or landing that power knee over and over.

I have 5 (Link, Robin, Lucina, Pikachu, Shulk) but I'll explain why for Robin. Robin is an extremely diverse character, with magic and swords. I'm pretty sure a fully charged side A with the Levin Sword kills as low as 45%, depending on character. Arcfire makes for a nice defensive and offensive move, Elwind is an incredible recovery. Thunder-Thoron are just fun to use, but Arcthunder has the most utility. Enemies stuck in Arcfire/Arcthunder can easily be comboed off of (Arcfire into a mid air Arcfire when they get thrown upwards.)
