Leonardo Octave Marcellus Leone, Agent: Prince, The Elder Prince of Lions, the French Engineer, The "Fielitare". He goes by "Leonardo 'Leone' Octave Marcellus" sometimes.
The Eldest Child of the Three Heads of French Tech Conglomerate, "Leonetech", He's protective of his younger brother, Wallace, and of people he considers friends, like Gemma. Despite his closeness with family, he tries to distance himself from his parents because he doesn't want people dismissing him as just a "Spoiled Rich Kid", and wants people to judge his work as his own. Leone is an Very Skilled Engineer, and a Phenomenal Chef. It was later discovered he's a Surprisingly Good Shot, and picked up sniping at the recommendation of Jay, working with Gemma to create custom bullets with Unique Effects. He's surprisingly perceptive, and very skilled at setting off Domino Effects in his favor. A person of many Hidden Strengths, Leone's something of a cynic at times and often snarking at people he who annoy him (Everette)
