Two different Mario worlds are on the verge of colliding, as the Mario RPG world and Paper Mario worlds mash up in the upcoming Mario & Luigi: Paper Jam. Mario and Luigi are already set to get a power boost by joining forces with their flatter counterparts, but now it appears that they'll get another boost, thanks to to the power of Amiibo.
Nintendo is indicating official Amiibo compatability on its Japanese website (via Nintendo Inquirer), with characters from across several Amiibo lines able to be used. This includes the Mario, Luigi, Peach, Yoshi, Bowser, and Dr. Mario figures from the Smash Bros. line; the Mario, Luigi, Peach, Toad, Yoshi, and Bowser figures from the Super Mario line; Classic 8-bit Mario and Modern 8-bit Mario from the recent Super Mario Maker line; and the upcoming Green, Pink, Blue and Mega Yarn Yoshi figures from the Yoshi's Woolly World line.
Little known about how these figures will work at this time, but signs seem to point to the Amiibo unlocking special in-game cards that can be used over the course of battle.
Mario & Luigi: Paper Jam is set to arrive in Spring 2016 on Nintendo 3DS, by which point the Amiibo adapter for the older generation of 3DS hardware should be widely available. Of course, New Nintendo 3DS hardware has native Amiibo reader support, so those owners won't have to worry about such a thing. Those looking for a look at what the game will entail can read our most recent preview right now.
