Roader

The Roader is a motorized robotic enemy encountered in The Subspace Emissary in Super Smash Bros. Brawl. It has only one wheel, and it zooms at very high speeds. They are very powerful enemies, and can send players quite a distance. Its high speed is its weakness, however, because if the player avoids it, it may stop and collapse on the ground, vulnerable. Roaders often travel in groups.
