FaceBreaker K.O. Party
November 11, 2008
On the back of the box for the Wii version of FaceBreaker, the screenshot of the Punch-O-Matic minigame has the players listed as Mario, Peach, Yoshi, and Wario. Mario's image is not shown, while the other three characters' are respectively a pair of lips, a raptor, and a skull and crossbones.
Since the reference was only included in the Wii version of the game, it's possible that Electronic Arts had the license to use the names of characters from the Mario series, however since it's a very minor reference it's possible that they didn't need any authorization from Nintendo.
