Magikoopa

Magikoopas are enemies in the Mario series who first appeared in Super Mario World for the SNES. They're essentially more powerful Koopa Troopas who have the ability to generate magic via their magic wands. With this magic, they can transform regular blocks into enemies and create items out of thin-air as shown in many of the games. An example of this would be in Super Mario Galaxy where they would create Koopa Troopa shells through their wands and thrust them towards Mario or Luigi. However, their items were used against them when either of the brothers tossed the projectile back to the sender.
