Killer Bees are minions of Dark Gaia that appear in Sonic Unleashed. Though called "bees", they actually more closely resemble wasps. They have dark-green bodies with glowing blue eyes and stripes as well as glowing yellow wings and stingers. They are constantly surrounded by purple vapour.
Killer Bees are among the fastest of Dark Gaia's spawn. In combat, they move about erratically, avoiding Sonic's attacks and rapidly countering by dive-bombing with their stingers. Though these pests are quick, they are also weak and it doesn't take much effort to kill them.
