"Mario Kart 9" refers to the game shown in the initial teaser for the Nintendo Switch 2.

There are some weird characters in here; I included all playable characters from here.

Some options may resolve early, but none will resolve until the first Nintendo Switch 2 Direct.

• Update 2025-03-02 (PST) (AI summary of creator comment): Unlockable Characters

  • Characters that are initially on the cartridge but require unlocking at launch will be counted as playable.

• Update 2025-03-02 (PST) (AI summary of creator comment): Base Character Requirement Clarification

  • Only characters that are in their base form are counted as playable.

  • Alternate forms or transformations (e.g. Metal Mario, Tanooki Mario) do not count.

• Update 2025-03-03 (PST) (AI summary of creator comment): Character Naming Clarification

  • Base Form vs. Variants: If a character appears only as a variant (for example, only as Dry Bowser), it does not count unless the variant is conventionally used as the base name in the game.

  • Naming Conventions: In cases like Yoshi, although variants (Green Yoshi, Red Yoshi) appear, if the game traditionally refers to the character as simply "Yoshi," then that should count as the base form.

  • Case-by-Case Basis: The resolution may depend on established in-game naming conventions. For many characters, a color variation (e.g., Green Yoshi) is effectively the base character, whereas others (e.g., Dry Bowser) are not.
