Marco Rossi is one of the main characters in Metal Slug.
"Pull your finger out and get to the source code." -Marco's pet phrase.
This Italian-American went on to study at the military academy's special technologies college after attending a public technical high school. After graduation, he became a member of the Peregrine Falcons Special Forces Squad (commonly called PF Squad). Although gentle by nature, mentioning General Morden, who is responsible for the deaths of so many of his friends and comrades, will send him into an uncontrolled rage. He's one of the squad's expert agents and an intellectual whose hobby is computer science. A computer virus he created for fun once mistakenly attacked the army's central computer system. Penetrating through all of the security firewalls, the virus almost caused the launch of a nuclear missile. But he'll never admit this.
During the character info screen in Metal Slug SV-001, he is given the logo "Siliconhouse M's -custom build-" with a caricature of himself slouching at a computer desk. His nickname in the same game is "Intelligent Soldier".
Marco's computer science hobby also resulted in the creation of the AI MS-Alice. She was originally a virus that he stole from an unnamed nation, and Alice gained self-awareness after watching him work to bring her to "life". Marco cares deeply for Alice and becomes visibly worried when she becomes critically damaged.
He also takes care of Midori, acting as her guardian and watching out for her safety.
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 his first 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 has blonde hair with a large bang in front and black eyes. His military gear is a white headband, a white sleeveless shirt, red vest, and brown pants. Usually he wears black wristbands, but some artwork has with with black gloves.
In Metal Slug 6 and Metal Slug 7, Marco is most skilled with the Handgun. He can shoot twice as fast with the Handgun and his shots cause double the damage than other characters. In Metal Slug XX, Marco can rapidly fire weapons by holding (Up + Square + R). The only downside is that while firing he can't move.
