R.O.B. Sentry

The R.O.B. Sentries are enemies in the Subspace Emissary in the Wii game Super Smash Bros. Brawl. They appear in the following levels: The Research Facility, Outside the Ancient Ruins, and The Subspace Bomb Factory. They are based off the NES peripheral R.O.B., though their coloration is based on that of the Japanese Famicom. They are robots who are loyal to the Ancient Minister (the playable R.O.B.). The R.O.B. Sentry uses a two-armed punch attack. Two R.O.B. Sentries are sacrificed at a time to detonate a Subspace Bomb. R.O.B. Blasters and R.O.B. Launchers are more advanced varieties of R.O.B. Sentries.
