Once upon a time, I was playing pokemon when it dawned on me that I had never owned a raichu because of my deep love for pikachus. Hell, I captured tons of pikachus, even had some Pichus, but never once even thought about evolving them. So I went and got me a thunderstone to evolve one of my many pikachus. And for some sudden reason, Raichu became my second favorite pokemon! And I've loved them ever since.
