Peter Löwenbräu Griffin, Sr. is the protagonist of the show and title character. He's a man of Irish descent currently residing in Quahog, Rhode Island with his wife Lois Griffin. He was, however, born in Mexico, where his mother had tried unsuccessfully to abort him. According to "I Dream of Jesus", Peter attended Providence High School. Together, Peter and Lois have three children, Chris, Meg, and baby Stewie. After a mix up at a sperm bank, Peter also became the biological father of Bertram. In addition, he and Lois had a child named Peter Griffin Jr. who died when Peter shook him too much as revealed in "The Juice Is Loose". Out of pity he also adopted an intellectual talking dog named Brian who formerly lived on the street as a stray, an accepted fact in Brian's two adoption stories.
Similarly to Archie Bunker from All in the Family, Peter appears to be unintelligent and is consistently depicted as crude and lowbrow. He enjoys activities such as going to up-market tailors and farting inside the suits. His favorite pastime is watching TV. He is also very cantankerous at times and has a strong jealous streak in regards to Lois. A running gag on the show is Peter's preference for Pauly Shore movies over classic films such as The Godfather and Citizen Kane. He is also a huge KISS fan and followed them during the KissStock shows and even got a copy of Kiss Saves Santa for Christmas. Peter is also an ardent fan of Barry Manilow, though this is a fact he has been known to deny in public. Peter also mentioned that he enjoys the following breakfast cereals: Total, Trix, and Boo Berry. Peter has demonstrated himself to be an avid television fan, with his favorite shows consisting of Star Trek, Three's Company and Charles in Charge.
An I.Q. test in "Petarded" confirms that his low intellect places him in a category below mentally retarded. His mental shortcomings have resulted in various accidents to other people; most notably the death of his step-father Francis Griffin, and injuries on multiple occasions to his wife Lois. His attention span is also incredibly short. When he discovers his mental retardation in the episode, he closes his eyes while driving, wishing "it would all be over" and hitting Tom Tucker with his car instead. Given his short attention span, as well as his erratic and frequently inappropriate behavior, it is conceivable that Peter suffers from Attention Deficit Hyperactivity Disorder, or ADHD. In addition, Peter is often seen getting hurt mostly by his own fault.
Peter also has a habit of proving his masculinity, not wanting Lois to fall for another man. He is incredibly jealous of other attractions Lois has in her life, an attitude that tends to get out of hand in most cases; in "Stuck Together, Torn Apart", he goes so far as to punch his reflection in the mirror after Lois comments on it being handsome. In "Brian Sings and Swings", he tells Lois, "Remember what I always tell you, if I come home in the middle of the day and catch you having sex with someone, I'll kill you both" though when he catches her in bed with Bill Clinton in "Bill and Peter's Bogus Journey", he takes no hostile actions whatsoever. However, he seems not to mind the fact that she slept with other men before they met, just so long as she doesn't do so again; he is particularly proud of the fact that she once slept with Gene Simmons of Kiss when he discovers this in "Road to Europe", but forbids any sexual activity between the two now as seen in "Don't Make Me Over".
Peter seems to find it frustrating that he is "wrong" while Lois is "right" about issues all the time, and apparently takes these issues competitively, just waiting for the day she slips up. This day finally comes in "PTV" after settling a conflict with Lois about censorship on television that she appeared sure to win. In an ironic twist that forces Lois to concede defeat, Peter celebrates by opening a secret compartment within the ceiling containing balloons, streamers, confetti, and a banner reading "PETER'S RIGHT!"; Peter then claims that he set this up 15 years ago, suggesting that this had been a pretty major issue for him for quite some time. Curiously, in the non-canon episode "Da Boom", after Lois admits he was right about the end of the world and she was wrong, Peter makes no reference to the compartment, though he had been bragging about his "victory" for two weeks straight. Maybe the compartment had been damaged in the nuclear devastation.
Among the members of his family, he tends to treat Meg with the least respect; in "Peter's Daughter", for example, he reminisces about the various pranks he played on her, including tripping her, flicking her nose with his finger, and even shooting her at one point. Also, he wipes a boogie on her hat saying "Hey Meg...Proud of you". He is known to embarrass her at times and with things that mean the most to Meg; the entire family once huddled together to read her diary and continue after Meg catches them. However, later episodes of the series show Peter developing greater respect and unity between himself and his daughter such as in "Road to Rupert" and the aforementioned "Peter's Daughter", though these moments tend not to last for very long.
"I Dream of Jesus" reveals that his favorite song is the Trashmen's "Surfin' Bird", and loves the song to the point of repeatedly singing it, playing the record of it, and trying to convince others that "the bird is the word". In "Wasted Talent", a running gag debuted when someone, usually Peter, will be running and fall and then hold his shin exclaiming the sound "Ssss Ahhhh" once or multiple times.
In "Family Guy"Edit
Peter's best friends are Glenn Quagmire, Joe Swanson, Brian, and Cleveland Brown prior to his moving to Stoolbend, VA. They enjoy hanging out at their local bar, The Drunken Clam, drinking and chewing the fat. The four men (often without Brian, although he has joined them on several occasions) do many things together. Once the four friends entered and won a costume contest at an 80s TV convention, dressing up as the A-Team. On another occasion, their fishing boat was wrecked, and they were stranded together on a desert island. Peter also has other friends such as Mort and Muriel Goldman and nudists Dave and Dotty Campbell, with whom he is seen occasionally. He became friends with Brian's ex-girlfriend Jillian, which stems from their below average intelligence; she even asked him to give a speech on her wedding.
In a running gag, storylines are interrupted by unexpected fights between Peter and a giant chicken. These battles feature long strings of action film-style sequences, with explosions, high-speed chases, and excessive collateral damage to both property and innocent bystanders, ending with Peter the victor leaving the giant chicken for dead, only for a sudden movement to show that the chicken is still alive.
In "Da Boom", the feud starts over a trivial incident where the chicken gives Peter an expired coupon at the grocery store. The fight resumes in "Blind Ambition". In "No Chris Left Behind" the chicken is identified as "Ernie", and he has a wife named Nicole, also a giant chicken. Peter is invited to dinner with them after they realize that their fighting is pointless, but then they argue over who will pay the bill, and the fighting starts all over again. Ernie makes a brief, non-fighting appearance in "Meet the Quagmires", in which Peter unwittingly assaults the giant chicken at an 80s dance, retroactively providing Ernie with a grudge against Peter. Ernie the chicken appears in the Star Wars parody episodes Something, Something, Something, Dark Side and It's A Trap!, as the infamous bounty hunter Boba Fett.
Ernie was also mentioned in "New Kidney in Town". When Peter was hospitalized due to kidney failure, Brian offered to give Peter his kidney. In response to the family's shock, Dr. Hartman stated that this transplant was not the only crazy thing that took place in medical research, and said that he once attempted to clone a chicken. This resulted in the original chicken to grow human-sized, violent, and incredibly hostile. Peter paused at this, and stated "we need to have a talk later."
Story of Joining Sora's TeamEdit
When Sora, sent Ivy, Cameron, Ayane, Luffy, Tsukune Aono, Scanty and Kneesocks to find the Keyhole, while he, Kairi, Riku, and the other Keyblade wielders are in sick and can't go on missions until their fevers are gone. When Ayane was given a Keyblade from Yen Sid temporarily, she sought help from Peter Griffin after she saved him from Heartless and Subspacers. When Ayane and company to were directed to the Griffin House, Scanty explained about the Keyholes and other worlds. When Peter listened good, he quickly wanted to join and help after the mission gets complete. As the Griffins paired up (Brian with Scanty, Stewie with Kneesocks, Lois with Tsukune, Meg with Luffy, and Chris with Ayane), Ivy was by herself when she looked around the beach. When the week past by, Stewie managed to figure out where the keyhole is, and that's to bring together the Drunken Clam sign, their TV, and even peter's glasses. Once they were together Ayane used her temporary keyblade and managed to open the new pathway. As the mission was a success without any enemies, Peter and his family joined to help Sora save other worlds.
