The Flying Disc is a circular platform that is used to make someone fly around.
Overview
Bongo uses this to fight Goku, who is on the Flying Nimbus, in the air.
Trivia
- In Dragon Ball Xenoverse 2, Time Patrollers can use a similar vehicle called Vehicle Capsule 315 which slightly resembles the Flying Disc though it differs in that it can only hover above the ground slightly as it is not capable of true flight. However it is ridden in an identical fashion.
