BBat is a Badnik which was intended be found in the Hidden Palace Zone of Sonic the Hedgehog 2. It initially remained unused when the Zone was originally scrapped, but has made its official debut in the 2013 re-release version of the game.
It waits for the player to get closer and then it attacks by simply following an U-shaped pattern, ideally hitting Sonic at the lowest point of the arc.
- Interestingly this badnik isn't listed in any instruction manual, however it is referred to as "bbat" in the game's source code.
- Due to its internal name, it's unknown if any connection to BFish is intended.
- The concept was later reused as Batbot in Sonic the Hedgehog 3.
