The younger brother of Ultraman Leo Astra came from the desert Nebula L77 of the Leo constellation. After the destruction of L77 by the Magma Seijin Leo, Astra, and Leo's pet monster Ron were the last survivors, but Leo thought he was the last of his kind. During a battle against Litre and Garon Astra revealed himself on Earth to help Leo. Ever since Astra has saved Leo against several different aliens over the months that were too powerful for Leo to defeat himself. At one point Babylou Seijin froze Astra in a special type of ice in space and took his identity as he stole the Ultra Key. After Ultraman King revealed Babylou for what he was Leo saved Astra from his icy imprisonment, defeated Babylou, gave back the Ultra Key, and the two brothers became the first Ultra Brothers that were born outside of Nebula M78. Astra continued to help Leo after helping him destroy the Saucer Monster, Hanglar and even in Ultraman Mebius's time. Even though Astra is the least active of the Ultra Brothers his help and determination always contributes in the end.
