Every single Smash Bros. character is headed to the Nintendo Switch with Super Smash Bros. Ultimate, coming to stores December 7, 2018. During its E3 2018 live stream, Nintendo not only revealed that Ultimate will bring together the series' entire roster to date, but that a multitude of new stages and old ones, along with character tweaks and updates, would be coming to the latest Smash Bros. entry.

We got our first surprise look at the new Super Smash Bros. during what seemed to be a normal Nintendo Direct video March 8, before a giant Super Smash logo appeared in the sky and set fans ablaze.
