Gaia

 is a protagonist robot character in the series of Galaxia Bots.

Description
Gaia, though named after the Titaness of Earth, is male. He is the Star Guardian of Earth and later, the Sun. He is one of the ten star guardians who follows Ultron's wishes and assisted the four chosen children in defeating Sauron and his minions. After being separated from his fellow star guardians, he landed on Earth and hid himself in a cave deep underground.

Gaia is the first star guardian that Dylan, Jojo, Andy, and Lily met and acts as a father figure to all four, especially to Dylan. After Apollo's death, he took the role of the leader of the star guardians. Before and after being reborn, he fights using a great sword that can shoot energy beams from a barrel hidden inside the sword's blade. In his original form, his special star energy attack is Saundering Blade, a continuous assualt on the enemy using his sword and ends with a powerful downward slash. In his reborn state, his attack changes to Solar Storm Sword which is still an assault attack but with more hits.
