What's some "obscure" media you've hyperfixated on?

For me, it's lately been Spy vs. Spy. I love the art style and I find the characters adorable. I've even made my own ocs, and discovered that it has a very small community surrounding it. I bought the omnibus (read through the entire thing) and I've been browsing internet archive trying to read all of the books with the comic strips in them. I've watched every single official animation of these two silly spy boys. I crave more media!!!! This is probably the most "intense"(?) Hyperfixation I've had in a while.
