Steven Universe

Steven Universe is an animated show (as well as having tie in comics) about a group of aliens called the Crystal Gems and Steven the half gem. The show is normally in 15 minute chunks and airs on Cartoon Network.

Representation
The gems don't have a gender but are feminine presenting. There is lots of fandom head canons representation but the show also has plenty of very canon stuff.

Garnet is a fusion of two gems who are in love with one another so much that they are always fused. Pearl was in love with Rose when she was alive.

Stevonnie, the fusion of Steven and his best friend Connie, is nonbinary and has been confirmed to use they/them pronouns.
