Okay, so I am very guilty of the above.
I'm just addicted to his lightning attacks. The animations are awesome. As are the consequences...
My actual skills for SSB are pretty bad. I can never seem to jump back onto the playingfield when I fall off. I just play for fun, or when the mood hits me.
I chose Sonic to kick Pikachu's ass, because I still really like that character. I used to collect the comics when I was younger. I can also draw Sonic without trying, because I used to draw him so often.
