The Subspace Army (亜空軍 Subspace Army) is the antagonistic force of the Subspace Emissary mode in Super Smash Bros. Brawl. Headed by the Ancient Minister and under the guidance of Tabuu, its aim is to expand Subspace using Subspace Bombs and to pull areas of this world into it. Most of the enemies the player faces in the Subspace Emissary are members of the Subspace Army.
Some members of the Subspace Army, such as Poppants and Mites, appear as enemies in the Smash Run mode of Super Smash Bros. for Nintendo 3DS, with most also having corresponding trophies. However, they do not have any specific plot-related roles in the game. Some members of the Subspace Emissary such as Tabuu, Primids, Mites, Duon, and the Ancient Minister appear as spirits in Super Smash Bros. Ultimate. In addition, Galleom returns as a boss.
The Subspace Army consists of a number of enemies, the Primids chief among them. These enemies are created from Shadow Bugs, which are dropped from the Halberd. The Subspace Army also controls the floating Isle of Ancients and the Subspace Gunship.
The army's weapons, equipment, and troops are almost all stolen or copied. Mr. Game & Watch was used to create Shadow Bugs, which were then used to create a massive army as well as false characters. Samus's Power Suit was apparently stolen, and Pikachu was used as a power supply. The Dark Cannon is the most powerful handheld weapon used by the Army, and these were distributed among its Smasher leaders.
The following were deployed in areas where they could do maximum damage, and were used in cases where Primids would not be enough.
Primids are the Subspace Army's standard troops formed from clumps of Shadow Bugs. Their modest strength is made up for by large numbers. Specialization is also present, as there are:
In addition to their role as workers and bomb detonators, multiple types of R.O.B. defend the Isle of the Ancients:
Bowser commands a group of creatures from his own universe, composed of:
Other enemies found throughout the game include:
In addition to sending troops at their foes, the Subspace Army is more than willing to set up some devious devices in their bid to conquer the world:
