Peter Löwenbräu Griffin, Sr., born Justin Peter Griffin according to his birth records, 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. In "Padre de Familia", he was born in Mexico, where his mother had tried unsuccessfully to abort him. Peter agreed to abandon a revolt of his father-in-law Carter Pewterschmidt's servants in exchange for him using his connections to make Peter a United States citizen. 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. In The Real Live Griffins he was portrayed by Tom Arnold.
Peter's favorite pastime is watching TV, with his favorite shows consisting of Star Trek, Three's Company and Charles in Charge. He is also a huge KISS fan and followed them during the KISS Stock 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.
An I.Q. test in "Petarded" confirms that his low intellect places him in a category below mentally retarded. He rushes off to attend Quahog College just to count to three in "3 Acts of God". 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. When trying to impress Chris with his forward-thinking, Peter claims it is still 1998 in "Baby Got Black".
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 "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.
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, some episodes of the series show Peter developing greater respect and unity between himself and his daughter such as in "Road to Rupert", the aforementioned "Peter's Daughter", "Meg Stinks!", and "Peter's Sister", though these moments tend not to last for very long. In the latter, it is revealed that his reason behind frequently bullying Meg throughout the years is the abuse he suffered from his sister Karen Griffin.
"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.
Pre-Devil Beater moments
Peter was sent to a top-security asylum by Ineur, due to massive massacre on Studdton, where he was actually saving the civilians from Alien Chickens, led by Ernie the Giant Chicken. Few days later, he was rescued by his best friends (Quagmire, Joe and Cleveland). However, they were surrounded by mafiosos on their way to escape. All four brothers defended themselves against a wave of mafias.
After all mafias were killed, Peter was horrified that he witnessed his friends' demise. Peter vows his revenge upon Ineur by assasinate him cold-blooded.
