New leak! It looks like a fanboy's dream come true. Well...it sounds to good to be true.
The Random Username Leak (2/19/2014) -
http://www.gamefaqs.com/boards/633202-super-smash-bros-for-wii-u/68612494
*Chrom is a newcomer
*Palutena is a newcomer
*King K. Rool is a newcomer
*Bubbles is a newcomer
*All veterans from Brawl return
*Most, possibly all, items from Brawl return
*Tiki's Tear from Fire Emblem: Awakening is a new item. It apparently buffs a character and increases either their damage or damage tolerance.
*Medusa's Head is a new item. It turns enemies into stone for a little while when they are hit by it.
*The Tempura Bomb, also from Kid Icarus, is a new item. It turns enemies into Tempura for a brief period of time.
*The Ice Flower from the Mario series is a new item. It is the counterpart to Fire Flower, should be pretty self-explanatory. Freeze doesn't last as long as the Mr. Freezie
*Mr. Resetti, Shadow, Saki, and Andross all return
*King Hippo is a new Assist Trophy
*Mad King Gangrel from Fire Emblem is a new Assist Trophy
*Tom Nook is a new Assist Trophy
*Toadsworth is a new Assist Trophy
*Protoman is a new Assist Trophy
*Duster from Mother 3 is a new Assist Trophy
This sounds like a fantastic roster with the items, ATs and newcomers but, I doubt it's real.
