Boötes is traditionally depicted as a herdsman with two hunting dogs on a leash and a club in his other hand. In the sky, Boötes follows Ursa Major around the pole. In one story, the constellation represents a ploughman driving the oxen in the Ursa Major constellation, followed by his two dogs, Asterion and Chara (represented by the constellation Canes Venatici, the Hunting Dogs). The ploughman’s oxen are tied to the polar axis and their movement keeps the skies in constant rotation
The Bootes Saint appears briefly only in the anime adaptation, forming part of Athena’s army led by Sagittarius Sisyphos in the attack to Hades’ castle.
Boötes Bayer is the Silver Saint in the constellation Boötes in Saint Seiya Omega. He was initially loyal to the God Mars, but after his defeat, sides with Athena. Bayer can use the element of fire.
When Koga , Souma , Yuna , Haruto , Ryuho and Shaina come close to the Thunder Ruins, Bayer is the first to address them. Ryuho decides to face him, allowing his teammates to move towards the ruins. Shortly after Bayer is defeated, Shaina destroys the core of Thunder Ruins with the help of Aria.
