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 episodes. After the abandoned plan to kill Kyle off in Season Five (that honor went, predictably, to Kenny) 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. Your current "ex" in this AU.

Ike appears to idolize his older brother. He has often tried to follow him to school as shown in "Cartman Gets an Anal Probe" and "Cancelled". He often copies the words Kyle has said, even obscenities, as shown in South Park: Bigger, Longer & Uncut. Conversely, one of the few examples of Ike getting angry at Kyle occurred when Kyle interrupted Ike's news program and changed the channel. Kyle has superficial malice towards Ike, but in several episodes, most notably "Ike's Wee Wee," it is shown that Kyle does indeed love his brother.

Sheila is very protective about her family and has often led huge campaigns against beliefs and other such examples which she believes are unsafe, often going too far in her efforts and steamrolling her son in the process. She was the cause of the America-Canada War and was the leader behind "Mothers Against Canada" (M.A.C.). She also seems to be somewhat nosy, poking into things that are other people's business. For instance, when she found out that Gerald Broflovski and Stuart McCormick used to be friends in high school she arranged a fishing date between the two (which had bad results.) In retrospect, either the relationship between Gerald and Stuart OR the fact that the Broflovskis are from New Jersey may be non-canon, unless Stuart McCormick lived in New Jersey with Gerald prior, or Gerald and Stuart went to high school together in South Park or some other location,

Gerald seems to care about the environment and current events. He is typically portrayed to be kind and friendly, though he can be stubborn, sarcastic and impolite at times. Although he is seen as a primarily moral man, he is seen to get carried away with matters of money, which shows him to be corruptible, tempting him to do things he would normally find amoral and wrong, much to his shame.

Stan is generally the most tender and sensitive of the four boys. For example, in "Kenny Dies", he finds it difficult to see Kenny in his ill state, and in "Raisins" he becomes depressed after losing his girlfriend to Tolkien. Also, in "Fun with Veal", Stan is the only one who stopped eating meat completely when the boys found that veal was actually "tortured baby cow meat". However, in some episodes he does not seem to care when people die, as in "Dances with Smurfs" and "Chef Goes Nanners". Despite that, he generally has a very kind, sweet, gentle, and sensitive nature. He is also very open-minded and accepting of different beliefs and values. Kyles best friend.

Cartman is described in various terms, in short, he is a vicious, angry, self-absorbed, immature, destructive, sarcastic, snooty, loud-mouthed, lazy, and sociopathic child. He is the most foul-mouthed character in the show. He is also racist 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,

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. In earlier episodes, when an unknown term is introduced to Stan, Kyle, and Cartman, Kenny will be called upon by his friends to clarify, although Kenny sometimes does not know the meaning of the term himself. His muffled responses are often met with laughter or further confusion. Kenny does seem to act differently without his parka on.

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 Eric Cartman, especially in earlier seasons. Wendy is generally friendly to others and seems well-liked at school, but she is unwilling to let her beliefs be compromised by popularity. Your Best friend in this AU
