Sakurai took to the Miiverse with some Super Smash Bros. Samus shots to explain that, "Until now, you were only able to choose from four, or sometimes five or six colors for each character. This time, though, all characters have eight colors to choose from!
"The first four color schemes for Samus are based off her Varia Suit, Fusion Suit, Gravity Suit from Super Metroid, and the Dark Suit," and, below, "here she is in the color schemes of the Gravity Suit from Metroid Prime, Green Samus (a regular in the Smash series), the Light Suit, and Dark Samus. A total of eight colors."
The four previously unseen Animal Crossing Villagers were shown off as well.
