The Bat Brain is a character that appears in the Sonic the Comic series published by Fleetway Editions. It is a bat-based Badnik variant created by Dr. Ivo Robotnik. They were among the first generation of Badniks Robotnik produced and has posed a threat to Mobius since the doctor's early days.


One of the earliest models of Badniks, the Bat Brains and the Badnik army once tried to defend one of Dr. Robotnik's Neutrino Accelerator, but were no match for Sonic the Hedgehog.[1] A Bat Brain and other Badniks later tormented Tufftee, who got himself trapped in the Marble Zone, before deciding to turn him into a Badnik with the Portable Badnik Processor. Thankfully, Sonic came and destroyed the Bat Brain.[2]

After Robotnik dominated Mobius, Bat Brains joined an invasion of the Hidden Zone but were taken out by Sonic.[3]

Some Bat Brains were summoned by Robotnik to kill Sonic after Robotnik stole his powers and looks. However, the Bat Brains mistook Robotnik for Sonic and attacked him until Robotnik returned Sonic's powers, which he used to destroy the Bat Brains.[4] While useless Bat Brains were melted down to be repurposed,[5] others units aided with the Marxio Brothers' schemes which were foiled by Knuckles,[6][7] and ravaged the Casino Night Zone until Tails and his allies stopped them.[8] More Bat Brains tried taking out the Freedom Fighters and almost succeeded, but were foiled by Shortfuse the Cybernik.[9] On the day where Robotnik's tyranny ended, Bat Brains and other Badniks were called in by Grimer to stop the rebels in the Metropolis Zone until a global electromagnetic created by Super Sonic destroyed them.[10][11]

Later, at an operating station on Flickies' Island, Robotnik started building new models of Bat Brains which were more round and dreadful-looking.[12][13] These models would challenge the Freedom Fighters on a few occasions, during one of which they were commanded by Agent X.[14][15]
