Axl is the eldest, lazy, and hyper-confident son of the Heck family whose teenage bravado frequently masks a deep-seated affection for his eccentric relatives. As a high school athlete and stereotypical underachiever, he spends most of his time lounging around the house in his boxers, raiding the refrigerator, and tormenting his younger siblings, Sue and Brick, with his trademark sarcastic dismissal. Despite his apparent narcissism, chronic procrastination, and academic struggles, Axl possesses a hidden depth of charm and emotional intelligence, occasionally stepping up to protect his family and evolving from an irresponsible teen into a capable young adult who eventually navigates college life and a career in marketing.
