Saw this exact question being asked in the peepshow subreddit, which I'm not subscribed to but came up in my recommended.
So thought I'd ask it here, my favourite minor character from South Park has to be halfy. He was literally in like 2 episodes and then we never saw him again :'(
Who's yours?
The Goth Kids hands down. Henrietta is the best of the group, but they’re all fantastic. Every single goth kids episode is top notch for me, and I really hope they do another. I bet they don’t though, the Disney wannabe conformists living in their sunishine fairytale. Life is pain, life is only pain.
