what if pokemon could be double-typed. Not dual-typed, but having the same type twice. Like an electric/electric mon, or dark/dark, or psychic/psychic, and it would double STAB, resistances, and weaknesses. Seems straightforward and pretty reasonable, imo, for some mons to be "especially" elemental, or whatever. I could imagine the regis all being double-typed because of them being literal golems. Tornadus too, probably. And maybe some random mons that are more elemental, like Tangela's line, Munna's line, Tynamo's line, the Hitmons maybe, Vanniluxe becoming Ice/Ice after evolving cus of the 2 heads lmao, Hippopotas line, Grimer's line, maybe a couple others. Might be cool. What do you think?
