Marcus first appears as the A.I of his megamind that Lydia finds in the beginning of the story and he leads the others to the shock of others as they had no how the megamind worked. He knows exactly what to do and helps the team spefically Lydia.

It is revealed that he is the mind in the Megamind by Lisa Loud and she manages to recrate him flesh and bone through the megamind. This is when Marcus joins the B Team and works to stop the legion from getting the spear and altering the timeline. While Thawne gets, Marcus is spared as Lydia splits her trinket with him leaving them with Bender, Skipper, Twilight, Rick and The Louds. Marcus then works with Deathstroke and his unit to fight Thawne and he makes his own mech to fight the group with Lisa Loud and is among the team when they find the Spear.
