This is collection of monster sprites, concepts etc. that might work for Tuxemon. I am only sharing these links, the creators are in the links. Note: Most of the sprites have specific licences that need to be followed when using, other than Flamelings (the version by Surt) and CC0 Scraps.

Made a tuxemon specific collection on OGA instead of spamming links in this thread; Check occasionally for new additions.https://opengameart.org/content/tuxemon
Thanks for sharing. One key thing to look out for is 64x64 sprites, as that's the size we use. Of course, we can always make new sprites from existing designs, but at that point it can be faster to make them from scratch!
There's also some use for 16x16 up to 16x24 animated sprites, as eventually we might have tuxemon walking behind their trainers in the overworld.
BTW we have most of the Guardian Monsters already on the wiki. Some are really nice! https://wiki.tuxemon.org/index.php?title=Georg_Eckert
