History
When Sam, Shiro, and Matt were on a Kerberos mission, they were captured by the Galra Empire. And as soon as they were captured, they were taken to the main fleet for questioning, and then they were taken apart. For the next year, he spent a secluded position with other detained investigators, at that time, he and other imprisoned scientists did research and invented new technology for the Galra Empire. Later in season five, Zarkon planned to replace him with Lotor and Voltron. And as Lotor fought against Zarkon, Pidge and Matt rescued him. And as soon as Zarkon was dead, he returned to Earth to build Earth's defense. But as soon as he returned to Earth, Admiral Sanda, the leader of the Galaxy Garrison, forced him to remain hidden for the sake of hiding alien life. But a year later, he and his wife, Colleen, revealed to the world the truth of what happened with the Kerberos mission, and the Voltron Paladins have protected them. And as soon as Sendak and his troops invaded Earth, the whole Galaxy Garrison fought against them. And when the Paladins returned to Earth, they helped them defeat Sendak. And then when the Earth was rescued from Sendak and one of Honerva's Komar Mech, he went to help the universe with the forces of Galaxy Garrison and Voltron's allies.
