He also loves minions

Give me a moment

Yokai Watch? might have some adult jokes in it that will go over his head but overall it's a solid show, especially if he likes pokemon

would he be receptive to sailor moon?

p...okemon maybe?? i don't know cry

Oh! If you have Disney+, there’s Marvel Future Avengers

It is an anime
