Volcanion
Aptly called the “Steam Pokemon,” Volcanion is the only Fire and Water Pokemon that exists. It’s quite the contradiction—after all, Fire and Water are often the first types that most people think of when they consider type match-ups.
Speaking of contradictory type match-ups, Volcanion’s is representative of two of the three starter typings, and the only other Pokemon that does this is the Ludicolo line (Grass and Water type). This makes me wonder if someday we’ll get a Fire and Grass type Pokemon to complete the trio.
It’s too bad that Volcanion was distributed in X and Y with very little excitement. Since it’s a Mythical Pokemon, it was given out for a short period of time via Mystery Gift. Fire and Water are two of the most popular Pokemon types, so it’s disappointing that Game Freak didn’t give Volcanion more of a spotlight.
