An Ultraman that Gento Hiruma transforms into. He is a Giant of Light that came from M421, a blazar far away from Earth.

When Gento strongly desires power for the sake of justice, the transformation item, Blazar Brace, appears on his left arm. While strongly imbuing his wishes into the crystal Blazer Stone, which holds the power of light, he then loads it into the Blazer Brace and transforms into Ultraman Blazar.
