Shadow Bug

Shadow Bugs are a strange kind of creatures in Super Smash Bros. Brawl. Although named bugs, they don't look much like bugs and look like round dark balls. The Halberd stores all the Shadow Bugs and releases them across the Smash World. When a lot of Shadow Bugs form together, they can create Primids and possibly other enemies. Shadow Bugs, when they come in contact with trophies, can create another clone of the trophy. This clone is an evil side of the original character.

They are only found in the bodies of Mr. Game and Watches; they can be endlessly extracted from their body. Taboo makes good use of Game and Watch's strange ablity in the Subspace Emissary.
