I love 'em all, but if I had to pick i'd be: Pichu, (& it's evolutions) Pachirisu, (All-time fave!) & Plusle (I like it more than Minun. POKEMON RANGER!!).
Spiky-eared Pichu, Pikachu, Jolteon, and Raikou
I love all electric Pokémon, especially Pikachu's line, Pachirisu, Plusle, and Minun to name some.
My favorites are definitely Rotom, the Luxray evolution line, Plusle, and Manectric! ♥
Though you could probably tell by looking at my picture...
I also like the cute electrics, like Mareep, Plusle, and Minun.
Jolteon and Pikachu
