Stewart Gilligan Griffin, or simply Stewie Griffin, is a fictional character on and the main antagonist turned tetartagonist on Family Guy.

He was the main antagonist of the show's earlier seasons, however he later reformed and was replaced by the true main villain of the series.

Although starting off as a stereotypical mad scientist and would-be-killer of his own mother, but from the end of Season 9 he will he will change for the better. He is voiced by Seth MacFarlane who also voices Stewie's father, Peter Griffin and the Griffins' pet dog Brian.

Goals and ambitions
Stewie originally had two goals in life: to kill his mother, Lois Griffin, and world domination - however, as the series progressed, Stewie's desire for world domination lessened and he became more of an anti-hero, prone to mocking others for his own amusement but no longer hosting the obsession with matricide or conquest as he did in his earlier appearances.

When Stewie travels to the 1960s and falls in love in "Valentine's Day in Quahog", he learns that the infant he kissed is really his mother when Carter arrives to pick her up.

In the double episode Stewie Kills Lois/Lois Kills Stewie, Stewie appears to have finally killed Lois who a year after returns to Quahog, much to Stewie's dismay. At the Griffin home, Stewie takes his family hostage and, after killing Cleveland Brown, ties them up and forces Brian at gunpoint to drive him to CIA HQ. As Stewie gains world domination, a humiliated Lois shows up at Stewie's compound and after a bloody fight Stewie is killed, not by Lois but Peter. This all is revealed to be a holographic episode for Stewie to see what would happen if he gained his goals.

Personality
The entire Griffin family has gone through quite a few changes as the series has progressed, going from immature jerks to emotionally unbalanced lunatics. Stewie, however, progressed backwards and has become less evil with each season. The most evil plan he successfully pulled off was to trap a group of toddlers in a secret pit because they had displeased him. He called it "The Club of Forgotten Children" and they all presumably starved to death. Stewie would normally unflinchingly commit acts like murder, theft, hijacking, bombing and extortion among many, many others and embraced this depraved personality disorder of his. He never managed to kill a member of his family even though he tried to do so in almost every episode.

Since the fourth season, Stewie has become far less evil and more or less like the rest of the family had been in the first few seasons. Even so, Stewie has retained some of his malicious traits but directs them to other members of the world instead of his family who he has visibly grown to care for. Stewie was origionally a very unsocial kid who could not even have normaly conversations with his family. He instead spent his time building a huge array of weapons and gadgets which seemed capable of almost anything. His British accent and loathing for just about everything with a heartbeat were very noticeble in earlier seasons. Stewie also had an absurdly wide vocabulary in earlier seasons and used huge words for situations that did not require them.

In the present seasons, Stewie is far more laid back and flamboyant, even enjoying his family's company. One running gag with Stewie that has become popular is his sexual orientation. He has had crushes on several girls (i.e. Janet, Penelope), but has also been very public with his struggling homosexuality. He also seems to not completely understand sex. At first, he did not even like the topic; he recently appears to understand it more, but is still ignorant to some its more specific details.

He also once tried to befriend Bart Simpson in the Simpson's Guy crossover. However as both them have completely different bad guy personalities due to the difference in comedic style between both series (Bart pulls pranks and vandalism, though he has a few redeeming qualities and is not all bad, in contrast to Stewie who is more of a sociopath as he has a violent and disturbing personality), Bart became creeped out by Stewie especially after learning that Stewie kidnapped all of his enemies and chose not to befriend him.
