Mite

A Mite is a small stick-figure creature that debuted in Super Smash Bros. Brawl. In this game, they are often found en masse in the Subspace Emissary. They are easy to defeat on their own, usually with one hit, though they can be damaging in large groups. Mites appear in red, yellow, and green.

Mites have been confirmed to return in Super Smash Bros. for Nintendo 3DS as enemies in the Smash Run mode.

Trivia

 * Mites' faces are actually the Subspace Army's logo.
