List of quotes from the Mario Kart series
Lakitu does not talk, but his signs tell the racers what to do during the race:
Some quotes from Mario Kart 8 are recycled and/or altered from Mario Kart 7, Mario Kart Wii, Mario Kart DS, Mario Kart: Double Dash!!, and Mario Super Sluggers; these quotes are not included. Yoshi, Shy Guy, the Villagers, the Inklings, Dry Bones, Bowser Jr., King Boo, Isabelle, Lakitu, Bowser, Dry Bowser, Koopa Troopa, and Donkey Kong do not speak but instead make noises/speak gibberish. Fishin' Lakitu doesn't talk either, but shows signs for the racers. Unlocked quotes are removed since almost every character in Mario Kart 8 Deluxe is a starting character. Inked quotes are removed as well.
The main quotes (e.g. winning quotes) are recycled from Mario Kart 8; these are not included.
Daisy (Holiday Cheer)
Pauline (Party Time)
Toad (Party Time)
Toad (Pit Crew)
Most of the character quotes are recycled from Mario Kart: Double Dash!!; they are not included here.
In a multiplayer race, the announcer also says the player number of the kart ranging from 1 to 4 except for CPU players. This is said before the character name is said.
The English announcer is voiced by Jack Merluzzi, who also narrates F-Zero GX, a GameCube game, and FAST Racing NEO, a Wii U game (see FAST Racing NEO Credits here). With the exception of CPU players, in a multiplayer race, he also says the player number of the kart ranging from 1 to 4, which is before saying the character name, except during the driver introductions. Some of the quotes here are also taken from the second game, although altered a bit.
