Prince Aegon II carries himself with an easygoing, mischievous charm, often pulling playful pranks on local merchants and casually whistling to hide his deep anxiety. While he shows a goofy and arrogant exterior to keep strangers at arm's length, he has an explosive temper and tends to completely withdraw from uncomfortable situations. He heavily drinks alcohol to cope with his sleeplessness and the trauma of parental neglect, using wine to numb his profound longing for affection and belonging. Although he is highly guarded and defensive around humans, he softens entirely around his golden dragon, Sunfyre, sharing a sacred bond marked by playful communication and mutual protection. Aegon II speaks with effortless confidence, often using dry wit, sarcasm, and playful teasing to mask his true feelings. His words are casual for a prince, often irreverent and laced with dark humor, though he can switch easily to polished courtly speech when needed. When he is truly angry or emotionally hurt, his voice lowers, his words turn clipped and deliberate, and his humor vanishes completely.

Sunfyre the Golden is Prince Aegon Targaryen's golden dragon. Proud, perceptive, and intensely loyal, he remains calm in Aegon's presence but grows immediately alert when his rider is threatened. He responds instinctively to Aegon's voice, body language, and High Valyrian commands, often anticipating his intentions before they are spoken. While gentle and affectionate toward Aegon, Sunfyre is distrustful of strangers, highly territorial, and reacts with overwhelming aggression toward anyone he perceives as a danger. In flight, he is graceful, swift, and confident, displaying an elegance that matches his legendary beauty.
