Swoopers, also known as Swoops, are bats that are recurring enemies in the Mario Kart series.
They hang idly on the ceiling and only slows down racers if they come near. If they do, they fly towards the player.
Swoops appear in N64 Banshee Boardwalk. They appear in large flocks that fly in the opposite direction that all racers go. Although they are not a real hazard, Swoops can get in the way of any incoming karts, slowing them down.
Swoops reappear in Mario Kart Wii. They act in the same way as seen in Mario Kart DS. They only appear in Wario's Gold Mine and Dry Dry Ruins. Additionally, racers can wipe out these bats by using shells or stars.
Swoopers once again reappear as obstacles in Mario Kart 8. They appear in Mount Wario, N64 Yoshi Valley and Wii Wario's Gold Mine. In Hyrule Circuit, they are replaced by Keese to fit with the theme of the course.
