Minecart (vehicle)
Minecarts is a vehicle featured in some levels of the Subspace Emissary. Once touched by the main character, it gets into the minecart, they close and start themselves quickly along their rails. The minecart will deal massive damage to any enemy it hits. While inside the minecart, characters cannot be hurt, though they can be KO'd if the minecart passes a blast line. Characters can jump out of a minecart at any time, this is necessary to avoid being KO'd if the minecart's path takes it off an edge. Minecarts can also end their path by crashing into a wall, which pops its occupants up slightly without damaging them. The speed of minecarts increases along with the stage's difficulty.
Origin
The main concept of minecarts originates from Kirby Super Star, where Kirby could find slow minecarts in various locations that would take him across stages safely destroying all enemies in the way. However, the speed of Brawl's minecarts is more reminiscent of the Donkey Kong Country series, where quick reflexes are required to jump at the right time to escape death.
