Dr. Robotnik




The Bat Brain (バサラン Basaran?) is bat-type Badnik model created by Dr. Eggman. It first appears in the original 16-bit version of Sonic the Hedgehog. These small Badniks hang in dark caves, waiting for its victim to be below it and attacking from above.


Bat Brain, as its name implies, is a robotic bat that is commonly found roosting on high ceilings, their wings stretched over their bodies, showing only the tip of their blue head. Firm claws ensure the Badnik stays on the ceiling, until it finds a target in range, at which point it swoops down and flies using the engine on its back. Its wings, feet and engine are metallic gray in color, while its body is dark blue.

Game appearances

Sonic the Hedgehog (1991)


Bat Brain makes its first appearance in 16-bit version of Sonic the Hedgehog, it can be found underground in Marble Zone. It hangs above the player but it can easily recognized from cavern's roof sections. It drops quietly down and starts to fly directly at the player.

These badniks can easily get in the player's way, especially in challenging platforming sections. Bat Brain can easily be destroyed before or after the landing with Spin Jump.

Sonic Jump (2012)

Several years later, the Bat Brains made another appearance in the 2012 remake of Sonic Jump, where they can be found in Blue Sky Zone. In this game, they appear before the player like they did in the original Sonic the Hedgehog, hanging platforms and clouds below, until they drop and start flying while the player is close to them. These badniks can only be defeated by jumping into their underside.

Sonic Lost World

Bat Brains finally reappear in a console video game, in this case Sonic Lost World. During the game, it turns out that badniks, including Bat Brains, got hijacked by the Deadly Six. They appear in Windy Hill Zone 3 on the Wii U version. They have the same basic look as what they did in Sonic the Hedgehog, only now the badniks have tiny mouths. Unlike in previous games, Bat Brains are seen attacking in groups.

Powers and abilities

Bat Brain hangs on a ceiling, waiting for a target. When Sonic is spotted, it drops from its roost, unfolds its wings, and flaps towards him. It will cling onto another ceiling if it fails to do any damage. Bat Brain does not pose a huge threat and is easily dispatched.

Sonic the Comic

Bat Brain STC Profile

A late model of the Bat Brain in Sonic the Comic.

In the Sonic the Comic series published by Fleetway Editions, the Bat Brains were a part of Dr. Robotnik's Badnik army before, during and after his rule of Mobius. Because of the different artists, Bat Brains had sometimes a slightly, but also drastically different look. The Bat Brains were frequently called into battle against the Freedom Fighters and their allies until Robotnik was toppled as Mobius' ruler. While he was stationed on Flickies' Island, Robotnik started to build a more powerful and dread-looking model of Bat Brains.

Bat Brain in the Archie Comics.

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, the Bat Brains were among the first generation of badniks produced by Dr. Robotnik. While Dr. Eggman would go on and make more advanced Bat Brains, the classic ones were eventually rendered obsolete and got decommissioned.


The toy company TOMY has released a Bat Brain action figurine during the release of Sonic & Knuckles as it also includes a series of 21 Sonic figurines and these figurines came in packs of four under the Sonic & Knuckles label and were also released individually under a Sonic the Hedgehog label.


Missing Bat Brain
  • Bat Brain was supposed to appear at one point in the 8-bit version of Sonic the Hedgehog, but was removed from the final game. However unused sprites of Bat Brain can be found from game's code of the Game Gear version. Along with Roller, Bat Brain is one of badniks that doesn't appear in the 8-bit version.
  • Like Orbinaut, Bat Brain does not appear in the European or North American manuals, so its English name comes from comics and other merchandise. Similar to the aforementioned Badnik, it is known by its Japanese name ("Basaran") in Sonic Jam.
  • Bat Brains in Sonic the Comic issue 39 are seen able to fire lasers from their eyes; something that these badniks usually don't do.
  • In Sonic the Hedgehog #226 published by the Archie Comics, the Bat Brains that appear in the issue strangely have no ears.
  • There is an enemy from the Super Mario franchise called "Swooper", which has a similar attack pattern to Bat Brains.
