i have an idea for an AU: The Despair Kids. it's similar to your Futuristic Four Villain AU, but it has a few differences
This AU includes Riley from Inside Out, Hiro Hamada from Big Hero 6 & Meilin Lee from Turning Red
Their backstories are different from the ones from your Villain AU, in that they became villains from a tragic event and finally giving in to the despair rather than being raised by the villains, hence the title
The only one trying to stop them is Meilin Lee
*Sorry if the writing is bad*
