Wait, You're only allowed one character...?
Full Name: Jason Copernica Leonardo.
Nicknames: 'JL' 'Leo'
Occupation: Pilot Marine
Armor Aesthetics: Grey-Blue color gradient reflective visor, helmet which is designed aerodynamically. Less armored than average, featuring lightweight metal plate rather than the normal armor types, colored with blue stripes. Tacpad/UGPS on left wrist.
Equipment/Weapon of choice: Silenced magnum with dual taped ammo for fast reload, SMGs and combat knife.
Backstory: Less of a fighter and more of a protector, Jason, or, as his friends call him, Leo, decided to be a marine pilot, capable of fighting but also capable of getting into a jet, flying it, blasting down banshees with it and saving people with it. Personality-wise, Leo is friendly, happy to help out and lend a hand but also sometimes not afraid to pull out tons of insults just for fun. Preferring not to fight, rather, escaping, Leo is an experienced pilot and, while nowhere near as capable as Spartans or ODST's, is definitely able to hold his own in a firefight.
