If you want a crunchy system that can do modern fantasy, I would just use GURPS. The core rules cover everything you absolutely need, and then as you encounter elements where you want more detail, you can drop in supplements as necessary: Horror, Undead, Blood Types (vampires), Magic or Thaumatology, Martial Arts, etc.
(Magic expands on the magic system presented in the core book, Thaumatology presents alternative magic systems.)














Pokémon Infinite Fusion is really great! It’s Pokémon but you can fuse two monsters together to make a new one. A lot of the fusions have custom art! (The other ones are like that old Pokémon fusion creator that pastes one monster’s face over the other one, lol.)
Look for their Discord if you want to download it. All websites that profess to have download links are unofficial and may be malicious.
