Fire Soldier

"'The Guardians, we're.. We're all scattered, and broken, and so many other things. I genuinely don't know if any of us wants to see the others again, but... The world's in danger. I can't let you go out there alone and get yourself killed. But we're not enough to save everything; We need a team.'""-Crossover Mario to Finn Flier"

Crossover Mario, more commonly referred to as CM, is the youngest of the Crossover Brothers, a founding member of the Guardians, and the formerly brainwashed Vokun sleeper agent The Fire Soldier. Shortly after his creation, CM was taken away to be trained in secret by his eldest brother, the Crossover Knight. However, at some point he broke away from the latter, only to then eventually captured and semi-brainwashed by the Vokun. CM's original memories were kept intact, and he did not learn of the damage done to his mind under much later.
