Peter Griffin

"Roadhouse!"

- Peter Kicking

"You wanna hurt me? Go right ahead if it makes you feel any better. I'm an easy target. Yeah, you're right. I talk too much. I also listen too much. Oh, I can be a cold-hearted cynic like you, but I don't like to hurt people's feelings. But you think what you want about me. I'm not changing. I like- I like me. My kids like me. My friends like me, 'cause I'm the real article. What you see is what you get."

- Peter Griffin to Lois in Baby Not On Board. "You know, that's the difference between you and me, Lois. When life comes knocking at the door, you go and hide in the kitchen. I fling the door wide open and I say, "Peter Griffin here. What do you got?"

- Peter's most famous quote.

Peter Löwenbräu Griffin, Sr. (Peter Löwenbräu McFinnigan) (Born Justin Peter Griffin) is the main protagonist of the show Family Guy. He is an obnoxious, boisterous man and He's a man of Irish descent currently residing in Quahog, Rhode Island with his wife Lois Griffin. However, he was born in Mexico, where his mother had tried unsuccessfully to abort him. They 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. Out of pity he also adopted an intellectual talking dog named Brian Griffin 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. He can also be quite villainous at times.

Physical Strength and Adrenaline
He has shown a degree of Physical strength (at least enough to beat up normal people) & a very high amount of adrenaline, especially if he is focused in a fight.

Regeneration
He has also shown to have the ability of Regeneration, such as instantaneously growing back his hand at a fast pace. (And his severed Hand can form into an Evil Clone known as Retep)

Cartoon Physics
He also defies the laws of physics so as to perform certain degree of abilities which would appear to be low-level reality manipulation. (He even did this by creating his own gravitational field)

Hand To Hand Combat Skills
He has shown to be an Incredible Fighter, as he had fought Ernie The Giant Chicken in a sequence of action styled fights, showing that Peter always seemed to kill Ernie and win but reveals that he is still alive. Yet despite his experience in Fighting, Peter can get defeated by People who know basic or trained fighters such as Joe Swanson, Liam Neeson or Military Soldiers.

Radioactive Powers (Formerly)
During the episode "The Simpsons Guy", he gained radioactive powers during his fight with Homer Simpson after falling into the Springfield Nuclear Power Plant. He gained high levels of superhuman strength, speed, reflexes, stamina, healing, endurance, durability & senses. He even gained a vast increase in muscle mass & a vast loss in fat mass, He was also capable of flight at high speeds.

Personality
Similarly to Archie Bunker from All in the Family, Peter appears to be unintelligent and is consistently depicted as crude and lowbrow (though sometimes to a greater extent) and is uninterested in things that are high class (with exceptions). He enjoys activities such as going to up-market tailors and farting inside the suits. His favorite pastime is watching TV. 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 (to a certain extent, anyway). Peter also mentions that he wears the male deodorant Speed Stick to his wife Lois, saying "Smell my Speed Stick?" while he is standing behind her in the office. Peter also mentioned that he enjoys the following breakfast cereals: Total, Trix, and Boo Berry. Additionally, Peter is an avid Star Trek fan and at the annual Quahog Star Trek Convention, mistook a person with the mumps as being in costume as an alien.

An I.Q. test 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 Griffin. His attention span is also incredibly short. When he discovers his mental retardation in Petarded, he closes his eyes while driving, wishing "it would all be over" (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.

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 the episode 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 hed been a pretty major issue for him for quite some time (there was also a clown in the stall, but he had died after being in there for so long). 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, (in a flashback) 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. In early seasons, Peter cared for Meg, then for a while he was horribly abusive towards her, in fact for a while he would not have been considered a hero. However, it was revealed Peter was abused by his sister, Karen. He took his rage out on Meg, but after Meg saved him from Karen, he lessens his abuse towards Meg.

The episode 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 the episode 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.

Peter also accused Mr. Washee Washee of stealing his shirt, inviting him over for dinner and sneaking into his house to retrieve what he thinks is his shirt. When Peter discovers the shirt isn't his, Mr. Washee Washee challenges Peter to and defeats him in a fight.
