SSB4 with characters: [u'Lucas', u'Sonic']
Sonic could DESTROY Lucas.

SSB4 with characters: [u'Lucas', u'Ness']
I think Ness could beat Lucas because Ness is good and Lucas isn't.

SSBB with characters: [u'Donkey Kong', u'Sonic ']
This also depends.

SSB4 with characters: [u'Falco', u'Sonic']
I'm not even sure who would win.

SSB4 with characters: [u'Falco', u'Roy']
This match really depends on the skill of the character. A Roy main could beat a bad Falco, but a good Falco could beat a Roy main.

SSB4 with characters: [u'Ike', u'Sonic']
Sonic could easily beat Ike. His speed could outrun Ike because he is slow. You are wrong.

SSB4 with characters: [u'Link', u'Sonic']
Sonic could beat link 6-4.

SSB4 with characters: [u'Link', u'Toon Link']
NOOOOOOOO. TOON LINK CAN TOTALLY BEAT LINK.

SSB4 with characters: [u'Falco', u'Link']
Falco can spam reflect on all of Link's projectiles.

ProjectM with characters: [u'Lucas', u'Sonic']
Sonic could easily beat Lucas because Sonicś speed can outmatch Lucas.
