Mechakoopa is a type of Koopa that is controlled by a wind. They first appear in Super Mario World. It has also appeared in New Super Mario Bros. Wii. It only appears in the stages that have to do with the ship that Bowser Jr. controls. Mechakoopas also appear as enemies in Mario & Luigi: Dream Team. They are only fought in Dreamy Neo Bowser Castle in groups. In battle, they mainly attack by charging and jumping into Mario (and Dreamy Luigi). In Mario Kart 8, mechakoopas appear as obstacles in Ribbon Road.
