It looks similar from afar, but in the roster, Bowser Jr. is smiling.
Truthfully, I don't mind him or Duck Hunt Dog. I love Shulk, and the problem isn't even that I dislike Dark Pit and Dr. Mario.
I just want Mewtwo.
That would be the one thing missing. Lucas is DLC.
But I think it's fake for one reason. The trophy challenge in the smash direct.
The trophies that were shown were
Pseudo Palutena
Obviously we got Palutena
Tiki from FE:A
Robin is confirmed as a playable character.
Kraid
That means a metroid rep, could be Ridley, or another character.
Fi
We are going to get a Zelda rep. I'm thinking it could be Ghirahim because they are related, but it could be someone completely different.
If the trophy theory is true(Which I find it very likely) then this roster is false.
