My bro got the game for Christmas and he let me play it. I changed the color of the skins.
I did Dark Rosalina VS Daisy (Off-colored Peach)
I won.

Dark Link VS Marth
I won

Dark Link VS Sabrina
Winner: Dark Link
(Sorry Sabrina)

I also defeated and got the last person my brother needed to get.
"Dark Pit", I think he was called.
Took me 4 tries.
Won with Dark Link :D

I love this game so much.
