Major Mynah is a Mynah bird native of Cambodia that crossed paths with Ray Palmer when he was in the region on an archeological dig. When the bird stole a gold statue, Ray would go after it as the Atom. The Atom would witness the bird get attacked by a hawk and sent crashing into an ancient Hindu temple hidden in the jungle. After fighting off the hawk, the Atom would follow after the Mynah bird finding that it's wings had been damaged in the fight. Administering it first aid, the Atom would stumble upon Vieg Minh invaders within the temple and with the aid of the bird, would stop them from raiding it.
Naming the bird Major Mynah, Ray takes it back to America with him and brings it to his friend Carter Hall to examine the injuries sustained to the bird. Realizing it's real wings were damaged beyond repair, Ray and Carter would change into Atom and Hawkman and travel out to Hawkman's spaceship. There Hawkman would use his advanced scientific equipment from Thanagar to replace the bird with new mechanical wings that would enhance his flying speeds.
Returning to Ivy Town, Ray would go into action as the Atom riding Major Mynah to stop a bunch of crooks who had stolen the artifacts that he had brought back from Cambodia. After this adventure, Major Mynah almost gives away Ray's secret identity to his fiancée Jean Loring prompting Ray to develop a means of disguising Major Mynah in future adventures.
The Atom and Major Mynah's partnership would prove to be short lived, as the bird would only help him out in two subsequent adventures. First aiding him briefly in stopping an invasion of the alien Physalians and finally rescuing the Atom from a bunch of spies where were about to extract secrets from his mind using a Lobotikon device.
- Cybernetic Enhancement Major Mynah's wings have been replaced by mechanical ones enabling the bird to travel at speeds up to 180 miles per hour.
