Marco is a self-obsessed bully, who has a history of being the biggest bully in Los Volmos. He bullies the Rowdy Reds out of their park with a Pyrus Cyndeous, despite Cyndeous wishing to do the right thing. He takes over the park in Costero Canyada from the Rowdy Reds, which attracts the attention of Max, who is in awe of Marco seemingly raw power. Marco constructs a large stage for him preside over the park, as well as several monuments to himself, and uses Max as his personal servant. He refers to the park as his "kingdom", and uses Cyndeous to intimate anyone who would challenge him. He tricks Cyndeous by exploiting his lack of knowledge about Earth and convincing him that Marco's cruel tactics are "just the way the world works here".
