There are 20 playable characters in Super Mario Party. Released for Nintendo Switch in 2018, the game restored individual movement around boards after Mario Party 9 and Mario Party 10 had used a shared vehicle system.
The roster combines familiar characters with several unusual additions. Mario, Luigi, Peach, Daisy, Yoshi, Rosalina, Wario, Waluigi, Donkey Kong, Diddy Kong, Koopa Troopa, Hammer Bro, Dry Bones, Shy Guy, Boo, Bowser, and Bowser Jr. return or appear as playable choices. Goomba, Monty Mole, and Pom Pom join them as new playable characters in the series.
Bowser is a particularly important detail: Mario Party 10 had already allowed him to be controlled in its special Bowser Party mode, but Super Mario Party made him playable in the standard Party Mode. The number is also easy to confuse with Super Mario Party Jamboree, which expanded the roster to 22 by adding Pauline and Ninji.
