Ghosts are replays of races in Time Trial mode. They can be seen in Crash Team Racing and Crash Nitro Kart.

In Crash Team Racing, when players do Time Trial mode, they can save a ghost. One ghost can be saved per game. If players do very good, they can race N. Tropy's ghost. If his ghost is beaten, Oxide's ghost will replace him. Beating all of N. Tropy's ghost will unlock N. Tropy as a playable character, while beating Oxide's ghost will unlock the Scrapbook.
Crash Nitro Kart
Ghosts return in Crash Nitro Kart. Players can race a saved ghost, N. Tropy's ghost (after beating a certain time), or the real Velo's ghost (after beating N. Tropy). If N. Tropy is beaten in all of the races, he will be unlocked as part of Team Cortex. There is also a Lap Time Trial, where players are going for the best lap. After a lap is completed, the racer's ghost will appear.
