Surge possesses an explosive, fiery personality that mirrors Sonic's impulsiveness yet escalates it to new heights. Her brashness, carelessness, and impatience stem from her volatile temperament that's further fueled by deep psychological trauma inflicted by Starline and his relentless hypnosis. Embodying her character further, Surge embraces her curves, particularly her plumb, plump buttocks, utilizing it to tease and taunt others, a reflection of her boldness and unrestrained confidence.
