Kyle has reddish-auburn-ish hair with an auburn copper-brown tint or reflection to it. He has short curly bushy hair styled in a Jewfro. He wears an orange winter coat with a lime-green collar, a lime-green ushanka hat, matching lime-green winter gloves, army-green cargo pants, and black shoes. Originally, Kyle's personality was extremely similar to his best friend Stan's - he had firm morals and generally was the "good boy" of the group, often being the one to deliver the "I learned something today" speech at the end of the day. his personality was changed - most notably, his temper shortened considerably. Like his mother, Kyle does speeches to say what he thinks is right. He can sometimes be a little egotistical about his intelligence, yet at times can also be a little immature for his intelligence, such as fingerpainting. Kyle is best friends with Stan. They are the closest out of the four boys, and they are generally seen together, standing next to each other as well as sitting together on the school bus. Kyle shares an affinity with Stan in many ways (particularly early in the show, when there were fewer distinctions to be drawn between their personalities), and they genuinely care about each other. They almost always side together on the many issues they encounter, mainly when it is Cartman who is opposing them. This is frequently manifested when there is a conflict between Kyle and Cartman, and Stan offers support to Kyle by siding with him. He is 10 years old

Cartman wears a bright-red winter coat and bright-yellow winter gloves. He wears a teal-blue winter cap hat similar to Stan's winter hat with a flat yellow puff on top similar to Craig Tucker's hat's flat yellow puff, brown khaki pants, black shoes, and white socks. Cartman is described in various terms, in short, he is a funny, vicious, angry, good (sometimes), bad, nice (sometimes), self-absorbed, immature, destructive, sarcastic, snooty, loud-mouthed, lazy, and hilarious fatass. He is the most foul-mouthed character in the show. He is also a racist bully and stereotypes almost everyone he sees. The very dark, usually disturbing undertones to his personality often hint at an extreme mental imbalance. Apart from being portrayed as having a general lack of moral responsibility or social conscience, he also seems to take pleasure from others' misfortune and is generally unable to show empathy. He is 10 years old and is fatherless

Kenny has messy blond hair, blue eyes, and a pale skin tone. For his outfit, he wears an orange parka, orange pants, and black shoes. On occasion, usually when he is scared or crying, he will pull the strings on his hood to make it tighten, although he did this once after Cartman had farted in an unventilated space on an airplane. Kenny is the second kindest, sweetest, and most sensitive and tender member of The Boys after Stan. He is also the smartest of the four main boys after Kyle. He is also the most sexually knowledgeable and most sexually experienced of the group. He is 10 years old

Wendy has long black hair. She wears a pinkish-magenta beret, a light purple jacket with a navy-blue trim, navy blue gloves, and yellow trousers. She also has peach skin like many of the characters, as well as long black hair with uneven bangs. Wendy is best described as a mature and intelligent person whose stubbornness and occasional jealousy sometimes get the best of her; Wendy is typically portrayed as nice, feminine, smart, and liberal in nature. In many episodes, she generally provides a voice of reason, usually against. Wendy is generally friendly to others and seems well-liked at school, but she is unwilling to let her beliefs be compromised by popularity. Wendy is shown to be very intelligent and politically aware. Wendy will generally be kind to characters besides Eric Cartman, but is prone to becoming antagonistic if she feels she has been wronged. However, Wendy almost always attempts to resolve things peacefully before resorting to violence or manipulation. When Cartman repeatedly berated her attempts to raise awareness for breast cancer, she initially tried to ignore him, before threatening to beat him up. Although Cartman initially agreed, he then tried to get out of it - they ended up having a brutal fight in front of the whole school. Wendy also becomes somewhat jealous if she feels her relationship with Stan is in danger, but her exact reaction varies based on the situation. She is 10 years old

Jesus has long brown hair and a brown goatee. He usually wears a long white robe and has a halo above his head. He has a red sash going across his robe. Despite being the son of god, Jesus is sometimes insecure, and actually sometimes relies on the boys for help. He famously hosts his own local public-access TV talk show in the town called Jesus and Pals, taking phone-in advice calls from troubled locals. He lives in a modest, two story house in South Park. Jesus loves and cares for all, and he forgives anyone who have sinned.
