Jeff Fischer (American Dad!).png

Jeff Fischer is Hayley's husband, however prior to their elopement they had been a frequently on again off again couple. In "Haylias", Hayley was looking to leave the country, but is brainwashed by Stan Smith to stay and marry a Senator's son who turns out to be gay. In "100 A.D.", Jeff decides to elope with Hayley, which the whole family is against.

Jeff was brutally beaten by Stan's boss, Avery Bullock in "Bullocks To Stan". He was left bleeding and twitching on the floor of a diner after being thrown head-first into a wall, but seems to have made a full recovery. He has also recovered from being crushed under a heavy object in "Phantom of the Telethon" and having all his skin peeled from his body by Roger in "Love, American Dad Style".

Until "Joint Custody", Jeff had not spoken to his father for years and "his mother ran away before he was born". In that episode, he went to his father Henry Fischer's farm in Raleigh, North Carolina, when trying to escape from Stan and Roger. Jeff is wanted in Florida for possession of marijuana as he had skipped bail.

In "Naked to the Limit, One More Time", Jeff discovers about Roger being an alien and Stan has to kill one of them so the CIA wouldn't find out and risk his family. When Roger asks Jeff for a hug before he leaves, Roger tosses him into a tractor beam from a ship sent to pick him up from his home planet which takes Jeff away, leaving a stunned Hayley behind.

In "Lost in Space", he is forced to reveal the trickery of Emperor Zing in hiding true love from his people, setting off a revolution and escapes in a spacecraft, looking for a way to get back to Earth and to Hayley.

In "The Longest Distance Relationship", Jeff is able to communicate with Hayley though a CB radio and discovers a way to return to earth through a wormhole, but arrives 60 years in the future and learns that he cost her a chance to have a great life with Millionaire Matt Davis. Unhappy with having upset the family and giving the elderly Hayley a heart attack, he returns through the wormhole and tells the again-young Hayley to move on with her life as he sadly gives up on her, unaware that Matt is killed by Roger very shortly after.
