Voltron?

You're a Galra, well half, you were raised by members of the blade and fight the Galra with a rag tag group of misfits until you meet the Voltron crew. The two groups combined and you find yourself hanging out and falling for a man named Shiro and his clone Kuro. Although it keeps getting harder to hide your secret of being half Galra.
Disclaimer: I don't own any Voltron Characters but I own the Oc's that are in my voltron comic on the Voltron amino.
