Cyclons are an enemy exclusive to Nintendo Land, although they are similar to Thardus. They are an airborn enemy in the Metroid Blast game that float slowly around the area until threatened. It attacks by becoming a whirlwind high in the air and chasing the playing Mii character. They are vulnerable to normal shots only when they expose their weak spot (similar to Spore Spawn), but a charged shot can destroy them at any time. Cyclon Queens are larger Cyclons that constantly summon more Cyclons for her protection. It is killed in the same manner as a baby Cyclon, although it requires 3 hits to be defeated. The Cyclons' attack is similar to a Waver's corkscrew-like attack.
Cyclons are also a prize. Initially in their rock form, when activated it opens up and unleashes its (harmless) tornado attack with a whirring sound. The prize is found next to Animal Crossing: Sweet Day.
