Spiral Pegasus is a minor antagonist from Megaman X5. He is a Reploid who is one of the remaining members of the military group known as "Repliforce". He was in charge of the military's Air unit beforehand and was mentored by Colonel. Once the following conflict left Repliforce disbanded and much of its members killed, Pegasus regrouped whatever troops were left in an air base. In the midst of the later Eurasia space colony incident, he was one of many afflicted by the Maverick Virus and but he had unfinished business with the Maverick Hunters relating to theirs and Repliforce's conflict.

He is based on the mythical pegasus, and thus has the head of a horse and the wings of a bird. He possesses a tall mohawk evocative of a Roman galea helmet, and the Repliforce logo on his head. His armor is white with royal highlights of red and gold, including epaulettes on his shoulders, giving him a refined and militaristic appearance.

His variety of combat skills involve being able to fly at intense speeds fast enough to create afterimages of himself as well as using his wings to conjure small twisters with a single flap.
