List of drivers in Mario Kart Tour
Counting each Mii costume separately, there are currently 174 playable characters (175 if including Gold Mario, who appears exclusively in the Coin Rush mode) in Mario Kart Tour, the largest number of playable characters in a Mario game. Notable new playable characters in the series include Peachette, Pauline, Hammer Bro, Boomerang Bro, Fire Bro, Ice Bro, Monty Mole, Dixie Kong, Captain Toad, Nabbit, King Bob-omb, Kamek, and Chargin' Chuck, with Kamek and Hammer Bro being playable for the first time after having been considered but scrapped from Mario Kart 64 and Mario Kart Wii respectively. Some characters also make a return after a long absence from the series, such as Diddy Kong, Funky Kong, and Birdo, who were last playable in Mario Kart Wii, and Donkey Kong Jr., who was last playable in Super Mario Kart. Currently, there are only four Mario characters from previous Mario Kart games that are not playable in this game, those being Paratroopa and Petey Piranha from Mario Kart: Double Dash!! and Wiggler and Honey Queen from Mario Kart 7.
Miis also return from previous Mario Kart games in the Mii Tour. Like in Mario Kart 8, they have customizable racing costumes, with each costume having its own special item. There are currently 19 suits.
Upon launching the game for the first time, players will be given either Toad or Toadette. After the tutorial, they are granted a free pipe launch which grants Peachette, Metal Mario, or Dry Bowser. The Red Mii Racing Suit is also given as a free gift for players.
Unlike other Mario Kart games, characters are sorted by their rarity of unlocking them, via opening up randomized green or gold pipes with rubies. There are three tiers of rarity: Normal, Super, and High-End. While the Normal characters are easier to unlock, rarer characters have a greater amount of starting points and have more favored and favorite courses.
So far, the only changes in the main statistics that were found affect acceleration and weight, and depend on the kart size.
The chance of obtaining a frenzy is increased by the driver chosen, depending on their level and rarity.
