First Knight of the Apocalypse, Gratos (character)

"First Knight of the Apocalypse, Gratos", or simply "Gratos"', is a character in the Future Card Buddyfight anime/manga. He is one of the Hundred Demons who follow Yamigedo. He is from Darkness Dragon World.

Appearance
His appearance is mainly that of a tall skeleton-like figure who wears knight armor with a skull decor and a crown encrusted with several blue gems.

When he is using his powers, he takes on a blue-white aura that surrounds his entire body. Also, the center of his eyes glow with a white flame-like pupil.

He also rides a large white horse, similarly armored with the same skull decor.

Personality
He is quite loyal to Yamigedo and seeks to eventually restore his master to its former glory. However he has a low opinion of Ikazuchi, believing him to not be suitable to be Yamigedo's Buddy.

He is not above giving praise of the skills of other Buddyfighters, like Noboru and appears to have a type of honor-code, believing those who lose should suffer the consequences that come with it.

He is also quite opportunistic and manipulative as he is not above kidnapping people and brainwashing them if they can be of use.

Season 2
He makes his first appearance in H Episode 22, during Ikazuchi's and Noboru's Buddyfight in the Darkness Barrier, where he makes some positive comments about Noboru's skills. After the fight and Noboru's loss, he appears before everyone and kidnaps Noboru via teleporting away, despite the presence of everyone there, showcasing the quality of his skills.

Later within the waterfall hideout, he formerly introduces himself to Sofia and Shido, then goes on to brainwash Noboru, though he never explains why it took so long for him to show himself now when questioned by Shido.
