Kangaskhan was originally a Marowak evo, Blastoise was originall a separate Pokemon line with its own pre evo, Wartortle's fluffy tail now makes sense because there was going to originally be an even fluffier evolution, and there is a middle evolution for the Psyduck line. Holy shit. Gamefreak originally just cut some Pokemon out or slapped together originally unrelated Pokemon, and eventually spun drastic evolutions as a design philosophy, the crazy bastards actually pulled it off. Likely the same thing with the Kangaskhan line, Caterpie and Venemoth shenanigans, and probably more. Again, Holy Shit
