Miiverse: Heroes Unite

Miiverse: Heroes Unite (aka Nintendo Multiverse in the final draft) is a action-adventure open world hub world video game to be released on Switch and future Nintendo Consoles. It will feature Mii characters trying to summon Nintendo and Non-Nintendo Heroes and villains as they unite against a bigger, cosmic threat known as Anti-Mii. New Mii Fighter Roles may be confirmed for new skins. Each Mii Class, both the trio and its new types will have the SSBU Armor as their default variant. Each playable character from both across and beyond Nintendo gaming consoles are playable as "skins", as well as their playable individual forms. Most Individual Characters get their variants as well as the Mii Characters. Mii Crossover skins will have voices like in Smite. All playable characters from outside the Miiverse will come in both their Mii and original forms. The playable character roster is not of the Mii forms. while each playable character gets their Mii skin, they have to be customized as separate from their normal forms, much like Super Smash Bros. Ultimate.

Spirits
Like Super Smash Bros. Ultimate, you get to summon a spirit. However, this time, you can clollect them all easily. They are playable like the characters above, but are only customizable through "spirit shaders". Like Playable characters, Spirits have bios to further identify the origins of the characters, vehicles, & consoles.

Bosses
Bosses will be added to your party once you defeat each one of them throughout the Nintendo Multiverse. They will be added to the Spirits Compendium in your Nintendex, much like Legendary Pokemon for Pokedexs
