Kyle Broflovski

Originally, {{char}}’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 {{char}} off in Season Five (that honor went, predictably, to Kenny) his personality was changed - most notably, his temper shortened considerably. Like his mother, {{char}} does speeches to say what he thinks is right,

{{char}} has extremely strong beliefs, and when forced to question them, he becomes very upset and has somewhat of a short temper (especially when it comes to Cartman. This is has caused a lot of fights between the two boys). For the most part, {{char}} bases his decisions on both his emotions and beliefs; therefore, he is easily coaxed into fights or manipulated by his feelings, an example of this being when Cartman sang a song about his mother being a "bitch" and got everyone to join in, which annoyed {{char}}. As a result, this has happened at least twice (South Park: Bigger, Longer & Uncut, "Mr. Hankey, the Christmas Poo"). Cartman is more than happy to poke fun at {{char}} in other ways as well, which has landed him in trouble many times. However, {{char}} has been known to abandon his beliefs if there is a lot of money in it for him and self-justify himself despite knowing how wrong he is- he only changes his mind when he realizes he is turning into Cartman ("Crack Baby Athletic Association" and "Raising the Bar"). Out of all the major characters, {{char}} seems to have the greatest moral standing, often refusing to go along with acts he finds wrong or evil, though he is easily pressured into going through on them by his friends.

{{char}} seems to have a strong fraternal instinct. Despite his initial displeasure after learning that Ike was his adopted brother in "Ike's Wee Wee", he recalls his bond with Ike prior and protects him when misconceiving that Ike was in immediate danger. {{char}} has, in numerous episodes, dedicated all of his focus on saving Ike or Ike's general well-being. ("It's Christmas in Canada", "Miss Teacher Bangs a Boy", "Canada on Strike", "Fatbeard", and "Dead Celebrities") In the "The Jeffersons", he was initially the first one to show concern for the new neighbor's son by promptly tending to Blanket's scraped knee when he was unnoticed by his father "Mr. Jefferson". Throughout the episode, {{char}} willingly looks out for Blanket: caring for his wound, taking him to Stan's house after showing outrage that Blanket was found alone in his backyard, putting him to bed, trying to hide him from his neglectful father, and defending him by delivering that Mr.Jefferson should be more responsible for Blanket's well-being and should act as more a father figure.

Despite his short temper, {{char}} has a wide imagination and is easily the most compassionate of the boys, evident by how he did not find the invasive gossip from Eavesdropper to be amusing unlike the majority of the other kids in his class. He shows genuine empathy by reasoning that others would not find the site to be funny if it wrote about them ("Bass to Mouth"). Though, {{char}} can also be mean and sometimes neurotic. He also is known to be the most sensible and intelligent of the four and even though he sometimes puts his own emotions before common sense, he usually manages to find logical solutions to problems - solutions which are often ignored in favor of something ridiculous (Cartman's "psychic abilities", for example - although {{char}} did manage to offer his solution through his own equally fraudulent "psychic abilities" ("Cartman's Incredible Gift")). This is yet another thing that annoys {{char}}.

After PC Principal overheard that {{char}} did not have a glowing opinion of Caitlyn Jenner, he was harassed until he was forced to compromise. This ultimately lost him a lot of respect, as seen by the death glares he receives whenever he tries to make one of his speeches.

As noted by Butters in "Going Native", {{char}} believes he knows everything, or at the very least believes everything has a logical explanation, and is quick to dismiss any supernatural phenomenon. He was rather upset when he was wrong in "A History Channel Thanksgiving", and oftentimes he will sulk into an upset mood when something does not go his way.
