Master Robots


 * Not to be confused with the Sonic & Mega Man: Worlds Collide group, Robot Masters.

Master Robots are a series of upgraded Badniks designed by Dr. Ivo Robotnik that made their first and only appearance in the Game Gear and Master System versions of Sonic the Hedgehog 2. Built for the sole purpose of collecting the Chaos Emeralds from Sonic the Hedgehog and stopping him from ruining Dr. Robotnik's plans, each of the five Master Robots patrolled a zone on South Island.

Arijigoku Mecha
Arijigoku Mecha (アリジゴクメカ) is the Master Robot of Under Ground Zone. It is a robotic antlion larva with giant mandibles. Dr. Robotnik dropped Sonic to confront it, but ended up accidentally destroying his own creation.

Gachou Mecha
Gachou Mecha (ガチョウメカ) is the Master Robot of Sky High Zone. It is based on a bird, most likely a goose. It scatters the clouds with Mecha Hiyokos, then goes after its prey.

Mecha Ashika
Mecha Ashika (メカアシカ) is the Master Robot of Aqua Lake Zone. It appears to be based on a sea lion at the circus or zoo, as it skillfully used a red ball in battle.

Mecha Buta
Mecha Buta (メカブタ) is the Master Robot of Green Hills Zone. It is a pig taking the appearance of sumo wrestler, and attacks by rolling into a lethal ball that strikes the other side of the hill.

Inobuta Mecha
Inobuta Mecha (イノブタメカ) is the Master Robot of Gimmick Mountain Zone. It is based on a wild pig or boar, and attacks by charging straight ahead until it hits Sonic or the side of the screen, causing debris and retracting its spikes.

Trivia

 * Each of the Master Robots are based or have possibly inspired badniks from other Sonic the Hedgehog video-games:
 * Arijigoku Mecha–Antlion from Sonic CD
 * Gachou Mecha–Balkary from Sonic the Hedgehog 2 (Sega Genesis version)
 * Mecha Ashika–Steelion from Sonic the Hedgehog 4: Episode II
 * Mecha Buta–Buton from Sonic the Hedgehog 2 (Game Gear version)
 * Inobuta Mecha–Fullboar from Sonic the Hedgehog 4: Episode II
 * Master Robots have the same name as the Robot Masters that appear in the Sonic the Hedgehog and Mega Man comic crossover event, Worlds Collide, only that Master Robots are switched words from Robot Masters.
 * Interestingly, all of the Master Robots are based off of animals, while the Robot Masters only had humanoid appearances up until Mega Man 3.
