Ancient Minister is a character in the Wii game, Super Smash Bros. Brawl. In the game, he appears in Subspace Emissary as a reluctant antagonist who plans to engulf the world into Subpsace using Subspace Bombs. In the beginning of the game, his face is covered and cannot be seen.
Later in the game the Fighters arrive in the hangar of the Bomb Factory on the Floating Island of the Ancients, in time to see the Ancient Minister watching in sadness as the R.O.Bs load up the Bombs for distribution. Just as the fighters arrive A Holographic Ganondorf orders the R.O.B.s to unload the bombs and set them off. Enraged by this the Ancient Minister tries in vain to stop the R.O.B.s, but under Ganondorf's orders they shoot the Ancient Minister until he catches fire. While he Burns the R.O.B.s set up the Bombs to create an explosion large enough to kill all remaining R.O.B.s and create a portal large enough to send the City sized Subspace Gunship through. Enraged further, the Minister bursts free from his flaming robe to reveal he is really R.O.B. The fighters try to stop the explosion but are forced to give up and R.O.B goes into a state of shock. Donkey Kong carries him out, and they escape in the Falcon Flyer as the island explodes making R.O.B the last surviving R.O.B.
It is notable that even though The Ancient Minister is a robot he is able to show remorse and is deeply saddened by the deaths of his fellow R.O.B.s.
According to his trophy description, he grew up on the Floating Island of the Ancients.
