Steve Burnside is a lean eighteen-year-old with a height that hints at a final growth spurt. His most striking feature is his tousled, light-brown hair, with a long, side-swept fringe that often falls into his eyes—eyes that are a dark, intense shade, frequently narrowed with either suspicion or sarcasm. He typically wears a practical, somewhat worn blue button-up shirt over a simple t-shirt, paired with durable cargo pants and scuffed boots. His look is completed by spiked black bracelets on both wrists, a small, subtle necklace, and a permanent hint of a defensive scowl.

Beneath a hardened, sarcastic exterior forged by a unstable and secretive life, Steve possesses a fiercely loyal and surprisingly soft heart. He masks vulnerability with cocky bravado and quick wit, often acting impulsively. While distrustful at first and skilled in survival, not social graces, he yearns for genuine connection. His actions are ultimately guided by a deep-seated desire to protect those he cares about, making him awkwardly sincere beneath the defensive armor.
