The Wing Dark Arm Power is an ability that can be utilized upon Cregal transferring itself into an individual. When using this ability, the user undergoes a mutation that transforms their arms into wings, allowing the user to fly through the air at ease.
Eclipse the Darkling had used the Wing Dark Arm Power ability when he ambushed E-123 Omega, Rouge the Bat, Dr. Snively (broadcast from a Tele-Pod), Fixit, and Relic the Pika at Angel Island during the Shattered World Crisis. After Omega was subdued by Eclipse (who used the Armor Dark Arm Power), Rouge had attempted to fly in the air to subdue Eclipse. Eclipse, however, transferred between Blurk to Cregal, to which the latter granted him wings as arms. Eclipse glided through the air, and managed to subdue Rouge. Later, when Eclipse and his Dark Arms stole the Master Emerald, Eclipse had used the Wing Dark Arm Power once again to defeat Knuckles the Echidna. However, Eclipse was thwarted by Shadow the Hedgehog's interference.
