Sue Sue Heck (born February 29, 1996) is the socially awkward early-teen middle daughter of Frankie and Mike. She seems to fail at everything she tries out for, but her optimism and determination keep her trying again and again. She wears braces on her teeth. Her first and middle names are "Sue", as it was mistakenly written down twice on her birth certificate. She is usually in a cheery mood even though she is often put down by Axl. A running joke throughout the series is that nobody notices her or remembers her name, except for Reverend Tim Tom, whom she greatly admires. She is a huge fan of Justin Bieber and One Direction. Her birthday is February 29th, so she only gets to celebrate her "real birthday" once every four years and therefore becomes very excited about Leap Years.
When she was in eight grade she managed to get on the cross country team due to it being "no-cut". For the rest of the school year she wore her team sweatshirt everywhere, which caused her to faint in one episode because of the heat. Cross country was later cut by the school board.
Upon starting high school she was briefly a part of the cheerleading squad due to a mix up in phone calls. She then decided to start a cheerleading squad for the wrestling team, which was approved by the coach because nobody else wanted to do it. There are currently three other girls on the team, all of them being even more socially inept than Sue is.
Her closest friend is Carly who she is mostly seen with. She is about the same on the school popularity scale, although one time Carly took off her glasses and braces and became more popular, especially with boys.
Sue's first boyfriend was Brad, but after she found him smoking, they broke up. Sue started to date Matt in The Map, but they broke up in The Paper Route due to him moving away. She dated Axl's friend, Darrin, but they broke up. But, they both still have some feelings for each other which was proved in Season 5. It seems that they will get back together since Darrin broke up with his girlfriend, and they both are obviously stil in love with each other.
