斯图威·格里芬

斯图尔特·吉利根·「斯图威」·格里芬（Stewart Gilligan《Wizard》评选其为有史以来最伟大反派第95名。在中国大陆，因头型酷似饺子，故被诸多观众以及粉丝称之为饺子。
Stewie's head has the shape of a rugby ball. In the episode "Stuck Together, Torn Apart", a cutaway shows Stewie's head to be normally shaped, until he hits it on the ceiling while bouncing on the bed, and it is elongated into the familiar shape. Flashbacks in "Chitty Chitty Death Bang", however, show his head was already shaped like a football when he was born.-->
Ambiguous sexuality.
Stewie's sexuality, even though he is a one-year-old, is ambiguous. When the writers began to flesh out Stewie's character beyond being a generic supervillain in season two, MacFarlane and the writers began to explore the infant's sexuality with a series of one-off gags, which hinted in "Chick Cancer" and "We Love You, Conrad" that Stewie could be gay. One example is in the episode, "Brian and Stewie," where Stewie's cellphone screensaver is of a muscular man. Another is where he has a picture of Chris Noth in his wallet and he expresses his wishes to have sexual relations with Brian's son, Dylan. When he plays with a baby girl, husband and wife living in a little house in the garden, he discovers she has a boyfriend. He then burns the house and kills them, then asks Brian why he couldn't do the same things with a friend he must with women saying, "Why doesn't that exist?," Brian answers, "That does exist, it's called 'being gay.'" Stewie then says, "That's what gay is? Oh yeah, I can totally get into that." In McStroke Stewie asks Brian what is like at Anal Point; Brian explains, "if you imagine it like a parking space, that you think, 'Gosh, there's no way I'm gonna be able to fit in there.' But then you fold in the side-view mirrors and, sure enough, well, look at that." to which Stewie responds, "Well, in that scenario, it sounds like I'd rather be the parking space than the car." It is also shown in "Road to the Multiverse", it shows a part of the multiverse where there are many homosexuals, and Stewie says "Love it." Then Brian says "Hate it." and they leave to another part of the multiverse. In "Something, Something, Something, Dark Side", Stewie (who plays the role of Darth Vader) threatens to "choke" the person in charge of the tractor beam. It turns out this person is a muscular man, whom Stewie does "choke", but not by neck. The muscular man states "I can breathe just fine...You're choking my-," and is interrupted by Stewie who replies, "I know." It is implied that Stewie is "choking" the man's penis as a means of grasping, suggesting homosexual action on his behalf.
On other occasions, such as when Stewie falls in love with a girl, Janet, in "Dammit Janet!", he has been shown to be straight. Also, in Baby Not On Board when Stewie is left alone in the Griffin home, he looks at a copy of Chris's "Hustler" magazine, he sees a picture of a vagina, then has a panic attack and screams before shooting it with a sub-machine gun saying in a shaky voice, "You...can't...hurt...anyone...anymore." In the commentary for "", the writers describe how they were going to make Stewie discover he was gay, but decided to scrap this idea in order to retain Stewie's sexual ambiguity for writing purposes. MacFarlane planned for the series' third season to end with Stewie coming out of the closet after a near-death experience. The show's abrupt cancellation caused MacFarlane to abort these plans, and the episode "Queer Is Stewie?" was actually produced, but never shown. Since that point, MacFarlane has opted to have Stewie portrayed as sexually ambiguous, as, in his eyes, the flexibility of Stewie's sexuality allows for much more freedom in terms of writing for the character.
MacFarlane later elaborated:
When asked why he made the decision "to take Stewie from homicidal maniac to gay little song boy?," MacFarlane answered: "It wasn't a conscious decision. Characters evolve in certain ways and we found that doing the take-over-the-world thing every week was getting played out and was starting to feel a little dated. It was weirdly feeling a little '90s and believe me, if we were still doing that, the show would be on its last legs. I only half-jokingly go by the guideline that, if it's something that might possibly ruin the show, it's a story we should probably do."-->
