pokemon_fusion has almost 1.9k posts and is defined on its wiki page as "Pokémon hybrids that are combined with different kind of Pokémon species." It implies both pokemon and fusion.
The problem is that while fusion and hybrid are similar tags, they are not the same. Fusion refers to combining two or more different characters into one, while hybrid refers to combining two or more different species. These can and do overlap; I would say that most fusions are hybrids, but most hybrids are not fusions.
Different kinds of pokemon are species, not characters.
At the very least what needs to happen here is for the pokemon_fusion -> fusion implication to be removed and a pokemon_fusion -> hybrid one to be added instead. And fusion needs to be cleaned off of the vast majority of posts. However, I am questioning the validity of the tag to begin with. Do we really need a specific tag for pokemon/pokemon hybrids? are pokemon/non-pokemon hybrids that common that there needs to be a way to filter them out of pokemon hybrid? I don't think so, so I think pokemon_fusion should probably just be aliased to hybrid, but I would like to hear others' thoughts on the matter.
EDIT: I just saw that there's the functionally identical pokemon_hybrid tag as well: "Any Pokémon that is an off-spring of two different species. While this tag is very similar to pokemon_fusion, this tag may incorporate for more biological and genetic aspect of an Pokémon offspring than magically fusing together with other Pokémon, usage of DNA Splicers, or took from the references of Pokémon fusion generators." This is a completely useless distinction per TWYS.
