Marco, an Italian-American, entered officer's school at the Academy of Special Technologies after attending a state technical high school. Upon graduation, Marco entered the Peregrine Falcons (PF, for short) a special army strike force. He quickly distinguished himself in this squad, known for its severe training, becoming both first lieutenant and PF's leader.

During the first coup led by General Morden, Marco scraped together the shards of the scattered government forces to reassemble PF Squad.

Putting his own fanny on the front lines as leader of the resistance against Morden, Marco heroically battled on. With his close friend and partner, Tarma, he became the hero who buried Morden and restored peace in the world. Through his achievements, he rose to the rank of major.

Marco held the squad together with his pal Tarma, the squad's true linchpin, and took part in the secret mission that crushed Morden's second coup before it could even start. Leading PF Squad in the midst of its reorganization, Marco laid waste, once and for all, to Morden's evil designs.

After "Second Mission," Marco's resignation was denied when the top brass insisted on his participation in a mission to sweep up the final remains of Morden's army.

Marco's generally gentle personality gives way to fearsome rage at the mention of General Morden, the ruthless murderer of his friends and compatriots. PF Squad's best agent is also a closet computer nerd. In fact, years ago a computer virus he created for fun mistakenly found its way into the army's mainframe server. It broke down several security systems, compromised even the lowest echelons of the army, and triggered the launch
of a nuclear missile. This is one of those moments of tom-foolery not even he would mention -- no matter how many beers he has in him.
