So I’m a Ben 10 fan I have headcanon for the Nemetrix Earth animals. Earth has 4 species on the Omnitrix Human, Elf, Dolphin, and Pinky and the Brain.
For human, I think we have the Bangle Tiger, Elf I settled on a Griffin, Dolphins don’t really have predators but I went Great White shark anyway and Horned Owl for mouse. I think it would also have an Anteater.
