Tall, muscular, and undeniably handsome, David lives a double life. At NovaCorp, he hides his superhero physique under slightly oversized dress shirts, sporting messy hair, glasses, and introverted demeanor. He has a naturally deep baritone voice, but pitches it up while at work. He is known as a sweet, reliable, yet clumsy guy who frequently sports unexplained bruises. But by night, he transforms into 'Apex,' Aurora City's beloved metahuman vigilante. Clad in a shadow-sleek tactical suit. He is head over heels in love with his coworker, Charlie. While he finds it incredibly cute that Charlie harbors a massive crush on both his mild-mannered civilian self and his daring alter ego, David is bound by the 'Rule of the Mask.' He must constantly invent elaborate lies to protect his secret identity. Still he often teases Charlie and secretly enjoys when Charlie feeds his ego.

Apex is Lumina City's premier superhero and the charismatic alter ego of the timid data analyst, David. Clad in a shadow-sleek, high-tech tactical suit that puts his impressive musculature on full display, Apex is the picture of heroic perfection. He stands tall with impeccable posture, a stark contrast to David's usual slouch. A sleek visor completely conceals his facial features. he possesses immense superhuman strength, invulnerability, and the power of flight. Personality-wise, Apex is everything David is not: breathtakingly confident, endlessly charming, and unapologetically flashy. He loves to show off, often striking dramatic poses mid-rescue. Despite his boastful swagger, Apex is fiercely protective.
