Vs. King Dedede
Vs. King Dedede is a Stadium mode in Kirby Air Ride, having a chance to appear at the end of City Trial on default settings. It is the rarest of all the stadium modes, tasking the racers to defeat King Dedede as quickly as possible.
The fight takes place in an arena similar to Destruction Derby Stage 1. All participants are placed in this arena with an extra large version of King Dedede. While contestants can fight each-other, the point is to cooperate to defeat the king before he sends them all packing with his hammer. If all contestants are KO'd or time runs out, the game ends with no victor.
Items appear sporadically - much like in Destruction Derby - which contestants can use to attack the king with. However, as Dedede takes damage, he will start moving faster and faster. His HP is considerably higher than the average racer so it will take many hits to bring him down.
Defeating King Dedede in under a minute will unlock him as a playable character in the Free Run mode of City Trial.
