For favorite electric type, right now I'd have to say Manectric. Lightningrod is just so useful. Completely neuters Thundurus, and an alarming number of people don't seem to know how the ability works. Power wise, Manectric can be a little lacking, but that can be remedied easily if you manage to grab a Lightningrod boost and it has awesome coverage. Most of the time it just sits there deterring electric attacks anyways.
