Why do so many retards in the fanbase want fusion to be a thing? The sprite combiner was fun, but people don't think Gamefreak would be able to implement something like that, do they? It would be limited combinations with the same handful of shillmon like all the other gimmicks Gamefreak has done. You'd get a Charizard x Mewtwo fusion, a Piakchu x Eevee fusion, a Lucario x Gengar fusion, and if you're luck a Blastoise x Venusaur fusion.
