Regime of Luna
At some point, Silvio Luna became the tyrannical dictator of Corto Maltese and had his right-hand man, Mateo Suarez, take control of the armed forces. The forces unfairly slaughtered many, delivering cruel punishments for even the simplest crimes. Sometime later, a rebel faction led by Sol Soria was formed to fight against the tyrannical reign, although little to no progress was made for them.
When Task Force X engaged on their mission, they managed to kill several of the team's members, although they suffered many casualties and Luna was assassinated by Harley Quinn as the mission progressed, leading to Suarez becoming the new dictator. They eventually captured and took Harley prisoner, although she is later freed.
They later went confronted Task Force X at Jotunheim and witnessed Starro break free, who eliminates the surrounding military forces before going on a rampage, placing Suarez under his control before Suarez is killed.
