Pokemon trivia question?
They have non-alphabetic characters in their names. I think they are all also pairs of different forms of the same basic pokemon… The Nidorans evolve differently but are still both Nidorans originally, the Porygons are different evolutions of plain Porygon (I think)… the only pair that throws me on that theory is Mr. Mime and Mime Jr. seeing as Mr. Mime evolves from Mime Jr. Also they use a similar colour: they all have pinky-purple on them.
