An image recently surfaced on the internet, supposedly taken from the final roster from the upcoming Super Smash Bros. While these leaked images are always susceptible to skepticism and scrutiny, this picture does hold at least some truth to it.
The truth of the image is its inclusion of every officially character confirmed to make an appearance in SSB. From Mario and Samus to Mega Man and Greninja, they are all there. The remaining characters in the roster include some familiar faces like Captain Falcon, Jigglypuff, and Game & Watch, plus one brand new character. This new challenger is Chrom from last year's Fire Emblem: Awakening, which was released on the Nintendo 3DS. All in all, this brings the Super Smash Bros roster to a total of 39 fighters.
Super Smash Bros. will release this Summer on the Nintendo 3DS and this Winter on the Nintendo Wii U.
