Ancient Minister

The Ancient Minister is one of the antagonists of The Subspace Emissary in the game Super Smash Bros. Brawl. He is the commander of the Subspace Army as well as the leader of the R.O.B.s. As commander of the army, he aids Tabuu in his plan to pull "this world" into Subspace using Subspace Bombs. He is capable of flight and the bottom part of his body can fire lasers. He can be commonly seen carrying Subspace Bombs around the land.

Background
Before the events of the game, the Ancient Minister was known as R.O.B., and he was the leader of the R.O.B. race of robots. His official title was the "Master Robot." R.O.B. and the other robots lived on the floating Isle of the Ancients and watched over this world. Indeed, R.O.B. was the overseer of this world, and was considered the world's "lord." However, this world was eventually invaded by Tabuu, an entity from Subspace. Tabuu attacked the Isle of the Ancients, killing many R.O.B.s and eventually taking the robots hostage. R.O.B. was forced to ally himself with Tabuu in order to prevent the deaths of more of his robot brethren. It was at this time that R.O.B. began to hide under his ceremonial robes of mourning and assume the name "Ancient Minister". The Isle of the Ancients was converted into a Subspace Bomb Factory and the Ancient Minister became the commander of the Subspace Army. As the commander of the army, the Ancient Minister led the invasion of this world on behalf of Tabuu.

The Subspace Emissary
The Ancient Minister first appears in the Subspace Emissary after Mario and Kirby's match at the Midair Stadium, where he detonates a Subspace Bomb, sending the stadium to Subspace. He escapes, only to be chased later by Mario and Pit in The Plains, who have little success catching him. The Ancient Minister then detonates another Subspace Bomb at the Battlefield Fortress, attracting the attention of Marth, Meta Knight, and Ike. Regardless of the group's efforts, the Ancient Minister manages to escape their grasp, however, he is soon discovered by Mario and Pit once again, along with Link and Yoshi. Again, the Ancient Minister gets away, but not before detonating yet another Subspace Bomb, sending King Dedede's Castle into Subspace.

The Ancient Minister is not seen again until Samus and Pikachu corner him at the Subspace Bomb Factory. Samus and Pikachu are ready to fight, but the Ancient Minister refuses, growing depressed at the amount of R.O.B.s sacrificed to activate the Subspace Bombs, confusing Samus and Pikachu. Soon after, Donkey Kong, Diddy Kong, Captain Falcon, and Captain Olimar arrive, also ready for battle, but the Ancient Minister still refuses. A hologaphic Ganondorf appears, quickly realizing that the Ancient Minister has betrayed him. Using a remote-controlled button, he is able to control the R.O.B.s, ordering them to attack the Ancient Minister and activate every Subspace Bomb in the factory.

The Ancient Minister reveals himself to be another R.O.B., and alongside the other heroes, is able to defeat the Auroros and other Subspace Army members that Ganondorf summoned to defeat them. Using the Falcon Flyer, the heroes escape the Subspace Bomb Factory before all of the Subspace Bombs detonate. From this point on, the Ancient Minister, now named R.O.B., joins the heroes in the fight against Tabuu.
