Mayday is the Copper Kidd's bird partner.
After the creation of Sky Shadow, the SilverHawks created avian partners to assist them. These four robotic birds were called the Fighting Hawks. Mayday is one of the four Fighting Hawks, created to respond to greater threats of the Limbo Mob. He was created to specifically support Copper Kidd.
Mayday is reddish copper hawk, mimicking his partner's metal. He can fly both in atmosphere as well as in the "space" of Limbo. Mayday has little if any combat ability. However, he has multiple sensor modes. This enables him to track a target from one end of Limbo to the other, or see obstacles or enemies around blind corners.
