A user from reddit that specialize in 3ds hacking has found files in the 3ds version that relate to all Dlc characters like Lucas, Mewtwo, Roy(FE) and Ryu (SF?) , knowing that the last time someone found some files likes these last year like Palutena mystery guidance, eshop icon, etc, have just been confirmed in today's update, I think its possible that Ryu could come to smash in the near future.

PS: Just received my email with the Mewtwo codes.

If this holds true, I'm very much pleased

Breath of Fire Ryu would be waaaaaay more interesting. But I admit, I do kinda want to see Roy again.

Now let me get my hands on the Ryu Amiibo. Hadooooken!

Don't care about Roy but Ryu is a cool addition. I hope Roy isn't a clone of every other Fire Emblem character and Ryu isn't a Captain Falcon clone though.

I seen this last neat. Would be pretty cool if true. I just hope they make Roy a lot more different then Marth and Lucina.
