Peter Griffin
Peter is married to Lois and is the father of Meg, Chris, and Stewie. He also has a dog named Brian, with whom he is best friends. He has worked at a toy factory and at Quahog's Brewery. Peter's voice was inspired by the security guards that MacFarlane heard at his school. His appearance was a redesign of the protagonist Larry from MacFarlane's previous animated short films ''The Life of Larry'' and ''Larry & Steve''. He has appeared in several pieces of ''Family Guy'' merchandise—including toys, T-shirts, and video games—and he has made crossover appearances in other shows, including ''The Simpsons'', ''Drawn Together'' and ''South Park'', in addition to fellow MacFarlane-associated series ''American Dad!'', ''Bordertown'' and ''Family Guy'' spin-off ''The Cleveland Show''.
As a character, Peter Griffin was initially praised by critics for his outrageous humor, absurd anecdotes, slapstick antics, and over-the-top, goofy yet endearing personality. Over time, however, reception has become more mixed. Some viewers have criticized his increasingly crude, mean-spirited, and offensive behavior, as well as his growing similarities to Homer Simpson in both personality and comedic style.
