|Family|| Mother: Frankie Heck|
Father: Mike Heck
Axl Redford Heck (born 1994-1995) is the athletic teenage son of Frankie and Mike, who can't be bothered to put on more than boxer shorts most of the time at home.
Axl began as a freshman at Orson High in season one, and is currently a student at East Indiana State University on a football scholarship. In season 5, Axl had a college roommate, Kenny, but currently lives with his friend Hutch.
Axl is the stereotypical older brother: sarcastic, lazy, and mean to his siblings. He will often do things without permission, expects others to pick up after him, moan whenever asked to do anything that resembles work and would rather hang out with his friends than be with his family. However, he has shown flashes of kindness to his family occasionally, and is good at heart. He is a trial for Frankie, who wishes he would be more open with her, as he was apparently a very loving "momma's boy" when he was a child, something Frankie seems to want to re-capture. He is very self-absorbed and often referring to himself as "awesome".
