Star Vs the Forces of Evil. The title character renounces her crown and destroys magic so it can't be used to oppress people (and monsters) anymore.

He appears to have...antennae? Is he TRYING to look like a cockroach in a Hawaiian shirt?

Also "The Doomed" by A Perfect Circle seems like it belongs here.

I would add Head Like a Hole and perhaps The Hand That Feeds, too.
