Ghost (Mario Kart series)
A Ghost is the recording of a player's driving performance in the Mario Kart series. The concept of Ghosts has appeared in every game in the series so far. Ghost drivers appear as semi-transparent characters, and will go through a race exactly how the player did when they got the highest score. These drivers' cannot be touched, but rather go through any other karts. Driving against one's own Ghost enables a player to directly match with his own record and thus to improve. Ghost data can only be recorded in Time Trial mode, and recording this data may be impossible in races that are too long in some games due to memory reasons.
The item Boo has been referred to as "Ghost" in Super Mario Kart. It makes a character look similar to the appearance of recorded Ghost data: invisible to other players and invincible. Template:Racers
