Imago

Imago is a giant fly creature first fought in its cocoon in Norfair. It can be defeated by freezing the winged Ripper guarding it, and then jumping on the Ripper and shoot the vines holding Imago's cocoon up on the ceiling. The cocoon will then plunge into a stone platform and open up the passage to Ridley. The second time you meet it, it will be in a room in Ridley filled with objects that look like eggs. By then it has hatched out of its cocoon and will attempt to defeat you if you crush or shoot one or more of the 'eggs' sitting on the floor. To defeat it now, tou have to fire missiles at his tail-stinger until it falls off. Imago will go beserk and break though another barrier-which happens to house a Super Missile Tank-and explode.
