Mites (マイト, Mite) are small stick-figure-like creatures that are part of the Subspace Army.
Mites appear as enemies in the Subspace Emissary mode. They come in yellow, red, or green varieties, though the color difference is just cosmetic. Their attacks do minor damage (3-5%) and seem to have fixed or very little knockback. Sometimes, they are spawned in mass from Subspace Generators. They are easy to defeat on their own, but are dangerous in the high numbers they spawn in. Their heads resemble the Subspace Army logo. Due to their small size, they are hard to hit and usually must be defeated with low attacks. They tend to attack with an aerial attack resembling a sex kick. They resemble Mr. Game & Watch in terms of movement and stance.
Pitiful little enemies that carry the Subspace Army symbols right there on their heads--rather, the symbols ARE their heads! They're paper thin--nope, no depth at all. There are three different colors-- red, green, and yellow--and all have white hands and feet. Their moves can best be described by the phrase "try really hard." They're weak, but they...try really hard.
In Smash Run
Mites return as enemies, keeping their Brawl behavior: they appear in groups and gang up on the player. Only Yellow Mites appear. Like in Brawl they can also be summoned by Generators.
Some Mites appear in the enemy waves in the generic version of the Vs. Enemy Team final battle.
These foes are part of the Subspace Army from Super Smash Bros. Brawl. They're paper thin and can easily escape a fighter's grasp. If you get too close, they'll jump-kick, but by themselves they don't pose much of a threat. Getting caught by a group of them, though, can mean some serious pain.
These stick-figure foes' heads are the symbol of the Subspace Army from Super Smash Bros. Brawl. When one gets near you, it'll leap up from aaall[sic] the way down there and do a flying kick. On their own, they're easy to handle, but groups can be overwhelming. Their sleek form also lets them slip free easily when you grab them.
Mite's name is literally the word mite, meaning something of little weight.
