During the Super Smash Bros. dedicated stream, director Masahiro Sakurai revealed that every single Super Smash Bros. character will receive an Amiibo. He also revealed the next set of incoming characters.
Duck Hunt Duo, Mr. Game & Watch, R.O.B, Falco and the three Mii characters were all revealed to have separate figures incoming. The Mr. Game & Watch figure also has interchangeable poses. Nintendo revealed that these new figures would arrive in North America in September.
Sakurai also revealed that DLC characters such as Mewtwo, Roy, Ryu and Lucas would all be getting Amiibo sometime in the future.
