When Koga and Yuna venture into the Wind Ruins, they discover that Fly has been designated to protect this place by Hornet Sonia, daughter of the god Mars. Fly paralyzes them both out of action with his Virus Sand technique and tries to steal their Clothstines to offer them to Mars, hoping to get a promotion to a Gold Saint. But Koga and Yuna awaken and attack Fly. The Silver Saint uses his Fly Slider technique against Koga, who counterattacks with his own technique, Pegasus Ryūsei Ken, and defeats Fly.


In the version of Saint Seiya Omega, the design of the cloth made a radical change, which has been completely repudiated by fans, calling it the worst armor that has appeared in Saint Seiya. Musca Fly's Omega version cloth is more robust due to him being obese and also the cloth color changed to green.


  • Sand Virus (サンドウイルス, Sando Uirusu): Fly breaths a cloud of dark gas toward his rival. When breathed in, the gas drains the victim of their life energy and paralyzes them.
  • Fly Slide (フライスライダー, Furai Suraidā): An attack by Musca Fly which uses brute force and the wind element. Fly flies through the air, then starts to spin rapidly towards his enemy.
