DC Comics x Pokemon (Batman)

I actually had an idea of a crossover between the underrated 2004 Batman series and Pokémon. There, Batman actually has TWO of the Pokémon shown here: an Umbreon (which was an Eevee and the son of his parent's Glaceon and Jolteon which were also killed that night) and Crobat (originally a tiny Zubat he met after falling into the caves below the manor, befriended and eventually fully evolved.) The only extra not here is a shiny Gengar who's a bit of a trickster and followed the Joker around at first, but left once he realized Joker's "pranks" weren't funny at all. Both Gengar and Crobat hide away in the cave to prevent anyone from connecting Bruce with Batman. Meanwhile Umbreon, when out with Batman, has a specialized costume that cloaks its body and mimics a shiny glittering similar to Gengar's. Since Bruce's isn't shiny (nor too active) many wouldn't think of it as Batman's.
