He has also been shown to have certain athletic prowess that is normally unattainable at his age, such as being able to lift or move objects of greater weight than himself.
His sophisticated attitude/nature and mannerisms are juxtaposed with childish interests and actions. He reads literature such as Christopher Marlowe's The Tragical History of Doctor Faustus and Sun-Tzu, and cites pop culture references that date much further back than his age would permit, however, he is also fascinated by Raffi and the Teletubbies.
His mastery of physics and mechanical engineering are at a science-fiction level. He has constructed a laser, advanced figher-jets, a mind control device, a weather control device, robots, a time machine, and even a robotic model of Peter that spoke in Peter's voice. Stewie employs these to cope with the stresses of infant life (such as teething pain, and eating hated broccoli) and to kill his mother with no success. He seems to be constantly carrying a concealed firearm, which he whips out whenever he wants to, he also carries around a bazooka and he keeps an M3 machinegun under his bed's pillow.
Wizard Magazine rated him the 95th greatest villain of all time.
His is the youngest child of Peter and Lois and was born in Quahog, Rhode Island.
