I like that Matt and trey originally said they were Stan and Kyle and then later said they were both cartman. He’s hilarious, he’s beautiful, his voice is flawless, he throws lil tantrums and plays with toys like Clyde frog because he’s still an 8 year old boy, but he’s also a devilish genius. We can see his character change in the earlier seasons as his mom continues to be a sl*t and sleeps with random men, he becomes angrier and more vengeful and more spoiled, he’s a product of his environment
