My favorite electric types are Pikachu and Luxray.
Pikachu, because way back when there were only 150 pokemon and I was a little bitty kid, ^^ Pikachu was my favorite pokemon of all. I liked it for its cuteness and I also thought it was pretty powerful if trained properly. I still like Pikachu, it's no longer listed among my favorite pokemon of all time, but I like it.
Luxray, because I love cats and I think there should be just a couple more strong feline pokemon. And Luxray can also learn things like Swagger, and some good dark type moves, too.
