Shadow Bug

Shadow Bugs are hazy, purple creatures that appear in Super Smash Bros. Brawl. The Halberd stores all the Shadow Bugs and releases them across the World of Trophies. When a lot of Shadow Bugs form together, they can create Primids and 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, and appear as the character with a purple tint. Shadow Bugs originate from Mr. Game & Watch, and an unlimited amount can be taken out from his body. When Tabuu learned of this, he used Mr. Game & Watch to create the Subspace Army. The Shadow Bugs are first seen in the Midair Stadium.

In Super Smash Bros. Ultimate, Shadow Bugs appear as an Advanced-class support spirit, using their previous trophy render. It occupies one support slot and any fighter that uses it will start battles with increased attack power but with 30% damage. The spirit's puppet fighters are four Mr. Game & Watches on the Omega form of the Pokémon Stadium stage. Aside from the Spirit Board, the spirit may also be available in Beedle's Tent, where it can be purchased for 1,000 Spirit Points.
