Frances "Frankie" Heck (née Spence) is the short, usually stressed wife of Mike Heck and mother of dense Axl Heck, dorky Sue Heck, and special Brick Heck. Frankie is the central character in the show and provides the voice-over narration.
Frances Heck portrays a neurotic housewife, struggling in suburban Indiana with mortgage, bills, poverty and an uncooperative and dysfunctional family. As a mother, Frankie was somewhat lazy but this is because she was spoilt in this regard as Axl, Brick and Sue were all easy children to deal with and was unprepared to react with Axl's moodiness, Brick's eccentricities and Sue's naivety as they developed. Both Mike and Frankie were rarely involved in their children's lives due to their jobs and other modern worries prioritised before getting involved and as such TV practically raised the three of them, causing more dysfunctions into their teen years. Although Frankie is mostly consent with the way her family behaves, she does wish her children were more like the Donahues but generally is too lazy and busy to put in time, effort or care to motivate them. She generally wishes her children to get far in life and mostly get out of her house but is not above helicopter parenting or making a bad situation worse when she accidentally comes off as a bad parnet in the public view.
In spite of her laziness, Frankie has natural and always-right maternal instincts which she treats with her family and as displayed during her job at Elhert's Motors whilst selling a car, in her daily life. However, she got let go from that jon in The Second Act, and now works as a dentist's assistant.
Mike and Frankie bicker over lots of things because Frankie is stressed and Mike doesn't really care. They consider themselves laid back parents and Frankie sometimes blurts out that they're lazy parents. Mike and Frankie bicker about a lot of things involving their children. According to Mike, Frankie isn't young and shiny looking anymore. Frankie tries to get Mike involved in some things like having a social gathering in the backyard for both Mike and Brick. Frankie invited the neighbor over to hang out with Mike and when Mike found out he got angry. He also didn't like the fact that she's telling new neighbor Don that he is shy. He then found out Frankie was telling him personal stories about his brother and dad. Mike considered Frankie chatty in his pro and con chart Marry Frankie. When Frankie finds the chart she freaks out because the chart had more negatives than positives and one of the positives didn't say what she was great at. Frankie made a similar one for Mike having an incomplete one which led into an argument. Mike did surprise her with a special anniversary gift even when they agreed not to get each other anything.Years ago on their honeymoon, Mike took Frankie camping which was terrible according to Frankie. During Valentines Day, Mike would go get a crappy gift for her.
Her oldest son, Axl Heck is lazy and stupid which causes Frankie to stress about getting Axl into college and studying for his Pre-SAT's. Axl isn't open with Frankie and doesn't want to interact much with his parents which hurts Frankie. Axl is Frankie's oldest son and Frankie feels like she is flying blind here. Frankie likes it when Axl hugs her. Frankie was honored to walk down the row with Axl for the homecoming game however Sue 's first cross country meet was on the same day and Sue wanted her to support her. Mike made a way for Frankie to be at both places which was great. Mike went to the homecoming game while Sue's meet took forever.
Everybody but Sue crossed the finish line and Frankie drove up to drive her to the finish line because she admitted that she would rather be at Axl's game than Sue's meet. Frankie drove Sue to the finish line for her to get out and cross it and made it for Axl's game and ran down the field when he got knocked down. When Frankie was studying to go back to college she realized how mean teachers can be which is what Axl's always telling her.
Sue is Frankie's only daughter and therefore has an emotional bond with Sue. Frankie is concerned about Sue's emotions bubbling at the top because Mike is very blunt and straight forward. Frankie supports Sue trying out for everything even though Mike and Frankie aren't interested in seeing her make it.
Sue is usually forgotten by Mike. When watching a drive-in movie, Axl claimed every parent has a favorite child. Their mother Frankie Heck denied it and Mike implied it was true. Mike claimed he and Axl have a lot in common, such as football and sports. Sue was upset. Sue took out a scrapbook and labeled it The Summer of Sue and Dad, and alerted her father about the project. Mike then started giving Axl negative attention and Sue none at all. Going to a fair, Axl had his school paper in his truck when he wrecked it and got towed. Frankie got upset and no one would listen to poor Sue. At the fair, Sue went to the lost and found for children wanting her family to wish to find her. After a while, the family came there to ask if they'd found the paper and left without Sue. At night, watching the fireworks, Axl stated he liked Mike better then Frankie. Sue got all worked up about how Mom does everything for them. Sue is also a very stressful teenage girl and sometimes gets in an argument with Frankie.
Brick is the weird youngest child of Frankie and Mike. Brick whispers to himself after something he just said. Brick makes Frankie do his last minute projects. Recently, Bricks whoops to himself, saying whoop (or "whooping"). Brick's strangeness results in his parents,
Frankie and Mike Heck, having to attend the annual talk with Brick's teacher. Frankie and Mike also have to attend his social group classes. In these situations, Frankie and Mike try to explain that Brick is not special or weird but in the end Frankie usually admits that he is special. Frankie and Mike pay very little attention to Brick because they have more important things to do which makes him feel "invisible" and is a great factor of his social ineptitude.
Frankie was a car saleswoman at Ehlert's Motors. She befriended an eccentric male worker named Bob who has a crush on her. She lost that job because she was the last hired and Dr.Ehlert needed to cut back. In the episode The Second Act, she vowed not to take any job that comes her way so she goes to tech school to get a real career as a dental hygenist but the instructor was mean to especially her. Frankie passed college and became a dental hygienist/assistant. Her boss is friendly Dr. Ted Goodwin who was feeling lonely for a while. He began to hang out with Frankie. Frankie accepted this because he signs her pay checks, and he's 5x nicer than her last boss Mr. Elhert but he could still fire her, and she's not that great at her job.
