We're fans of Daron Nefcy's Star Vs. the Forces of Evil here at TTDILA, she's been working on the show since 2011, but had the concept of the show before then. Check out the main character, Star Butterfly, as a delusional 6th grader with no magical powers. The early concept comic links below show a much sadder adventure for our heroine.
With the early version is a a cat named Cashew, Star forced to tag along on her adventures, the cat was adverse to this. Here's hoping we see Cashew attack her in some way in the series.

Our only gripe with the show is the awful voice acting of Jenny Slate as Flying Princess Pony Head.
