Master Robots

Not to be confused with the Robot Masters.

The Master Robots^[1]^[2] are a group that appear in the Sonic the Hedgehog series. It consists of the bosses that appear in the 8-bit version of Sonic the Hedgehog 2 and Sonic Chaos. They are an elite Badnik series designed by Dr. Eggman. Built for the sole purpose of collecting the Chaos Emeralds and stopping Sonic the Hedgehog and Miles "Tails" Prower from foiling his plans, each of the Master Robots patrolled a zone on South Island until their destruction at the hands of the heroes.

Trivia[]

The Master Robots are simply called "bosses" in the Japanese manuals, and do not have a group name to distinguish them. This may be analogous to how Badniks in general gained their name in English.
There is confusion over what exactly constitutes a Master Robot, as the scoring heading for both manuals has a separate entry for Mecha Sonic and Dr. Eggman's machines, and the latter one splits them between "Boss Robot (Zones 1–2)" and "Boss Robot (Zones 3–5)"; however, the text clearly states every boss in the zones' third Acts are included.^[1]^[2]
Sonic the Hedgehog Triple Trouble contains a similar group of enemies, but are instead labeled Boss Robots in English localization.^[3]
