Gengar is usually top of the list when ... its own Funko Pop. Outside of the core four I already mentioned, there's a strong case to be made that Gengar is the most popular Pokemon of all.

That includes plushies, Squishmallows, Funko Pop! figures, and Pokémon TCG products. If your collection could use a boost, this will be a solid time to grab a few favorites without paying full price.
