Skills & Abilities
Biscuit is a very smart and intellectual character and throughout the story has proven to be the brains of Tekkadan. Supports Orga in the role of a staff officer, and is always at his side during battles to help him with the issuing of commands. As Biscuit had attended school, he has good reading and writing skills. 
Like the other orphans employed by the CGS, Biscuit has the Alaya-Vijnana System implemented into his body, and even though he doesn't pilot a mobile suit, he has displayed adept skill in operating a mobile worker in harsh terrains.
Biscuit enlisted with CGS to support his family.
When Orga along with Biscuit, Mikazuki and the other orphans founded the Tekkadan, he promised to help Orga build Tekkadan into a big mercenary company.
After being informed about Savarin's death, he had a fallout with Orga (who is unaware of Biscuit's brother death at the time) due to his notion to stay on Earth and continue fighting, while Biscuit was against this because it would put every member of the Tekkadan at risk, and he didn't want to consider the possibility of losing anyone close to him again.
Biscuit is killed in action by Carta Issue, while piloting a Mobile Worker with Orga, he throws him off the vehicle just in time to save him, while his Mobile Worker is cut in a half by Carta's Mobile Suit. With half his body trapped under the crushed wreckage, he desperately tries to crawl out, saying how he can't die yet as he needs to get back to Mars and send his sisters to school and build up Tekkadan, but he doesn't survive the injuries and dies in front of Orga.
He is childhood friends with Orga and serves him like a staff officer. When Orga wants to make a strategic decision he discusses it with Biscuit first. Additionally Orga mentioned that every since they were little whenever he proposed something reckless Biscuit never defied him at all, Biscuit argued that he did, just that Orga wouldn't listen.
