Hayley Dreamsmasher Smith-Fischer is a fictional character from the animated television series American Dad!

Across the series, Hayley's storylines typically involve her liberal opinions clashing with her father's staunch conservative beliefs, and her on-again-off-again relationship with boyfriend Jeff Fischer, whom she marries in the show's sixth season.

In the third-season episode "Stanny Slickers II: The Legend of Ollie's Gold", it is revealed that her middle name is Dreamsmasher, as given by Stan.

Hayley is Stan and Francine's new-age hippie daughter who, despite being a married adult for much of the series, still lives under her parents' roof along with her husband, Jeff.

[8] At times, Hayley is casually rude and insulting in attitude especially towards her brother, Steve, which can be described as sibling rivalry.

This is primarily because of Hayley's disgust for Steve's obnoxious tendencies and generally shallow taste and desire towards the opposite sex.

She is often disrespected by other more shallow and self-involved members of the household who seem to find her annoying and are contemptuous of her kinder and more selfless character, especially Stan and Roger.

The fourth season has started showing that Hayley is often prone to violent and uncontrollable mood swings.

These mood swings terrified her parents and they were fearful of the same problems in her brother, although it is shown Steve has had his temper more under control.

While still the most empathetic and possibly most sensible member of the Smith family, Hayley's generally intelligent and independent character becomes more at doubt in later seasons.

At this point in later seasons, Hayley's morality, sensibility, and seriousness have become much further in comparison to the rest of her more shallow, reckless, and muddled family members, and even Roger.

The other potential father to Hayley is Joel Larson, a complete stranger who Francine slept with three days before she and Stan got married.

In season 5 episode 15 "Merlot Down Dirty Shame" it is revealed she and Klaus also share a telepathic ability to communicate.

Reginald, a talking koala who works for the CIA, befriends Hayley in the episode "Family Affair".

Embarrassed, she apologizes to Reginald in "Cops and Roger" and suggests a double date with him and his girlfriend Rhonda and her (temporary) boyfriend, Ian.

At the end of the episode, Stan has a change of heart after he sees how hard it would be for them to make it on the salary Jeff brings in.

However, at the end of the episode, the Collectors are willing to put Jeff's brain in Zebleer to make Hayley happy.

In the episode "Haylias", there's a scene where Hayley tells her parents that she's planning to leave the United States to go to France to live a more uninhibited life as well as engage in a string of wild love affairs, including one with a woman named Simone.

But, due to how difficult Roger was during the pregnancy, Hayley feels that she isn't ready for a baby and Jeff agrees, having just been born himself.
