Over the last (literally) Direct dedicated to Super Smash Bros. Ultimate, in which it was revealed that Sora by KINGDOM HEARTS will be the last DLC character in the game for Nintendo Switch, six new ones have been announced amiibo coming soon in stores. It is about Sephiroth (FINAL FANTASY VII), Kazuya Mishima (TEKKEN), Pyra And Mythra (Xenoblade Chronicles 2) and finally Steve And Alex (Minecraft).
Only the latter have a launch window, namely the spring of 2022, while the others are still in the planning stage. The amiibo for Min Min by ARMS will see the light in the course of spring. No news regarding a possible amiibo from Sora, but we believe it is only a matter of time.
