Here is the full list of new Mii Fighter costumes for SSBU that will appear alongside Tekken’s Kazuya. And here’s a trailer looking at those four character costumes in-game.
The next round of SSBU Mii Fighter DLC showed up, and it includes Tales of Symphonia’s Lloyd and Devil May Cry’s Dante.
These are only some of many Mii Fighter character cameos costumes in SSBU.
During the Kazuya Super Smash Bros Ultimate presentation on June 28, 2021, we learned about additional character cameos.
