An adventurer James and Storm rescued after he was taken by ants
Marvin was the only one to believe Jmaes and Storm when they gave warnings of an incoming ant invasion; he told the guards and a defence was set up. Marvin was taken by the ants in The Ant Battle of Arcion before being rescued by Storm, James, Aria, Nerphonia and the shifty party. After this, James invited Marvin to the party, he accepted, and so his adventure truly began.
He enjoys the company of his compatriots, though shows disapproval when Storm goes on a murderous, psychotic rampage.
