The Whisp is a small flying Badnik modelled after a fly. It has a rounded blue body, a yellow mouth, large red eyes, six small legs and a grey motor on its behind. It flies using a pair of insectoid wings on its back.
The Whisp poses little threat on its own, but is commonly found in groups of at least three. When they spot a target, Whisps will swarm in and buzz around the victim, butting into them repeatedly.
Sonic the Hedgehog 2
In the 16-bit version of Sonic the Hedgehog 2, Whisps appear in the Aquatic Ruin Zone. Encountered in groups of three, they emerge from the foliage around the stage to attack the player. They continuously buzz around the player causing contact damage unless the player destroys them all or runs far enough away. They can easily be destroyed with any attack.
Sonic Pocket Adventure
Whisps make their second appearance in Aquatic Helix Zone. Their behaviour is identical to their last appearance in Sonic 2.
Sonic the Comic
In the Sonic the Comic series published by Fleetway Editions, the Whisps are a part of Dr. Robotnik's Badnik army. They only appeared a few times during the comic's run. One time, they attacked Sonic when he tried to investigate the Aquatic Ruin Zone, at which point the Whisps were armed with lasers. Years later, many more would ambush the Freedom Fighters over Flickies' Island.
