Although some of you might not count Nightbird as a Decepticon or a Transformer for that matter, I do thus she's here on this list.
Shame she only appeared in one episode in the G1 series as I quite liked her, I mean you don't really get many non fan-fic female Decepticons do you? The only two non fan-fic ones I can recall is that one from TF: Cybertron (I can never remember her name) and Slipstream from Animated and War For Cybertron (she's also in my G1 fan-fics).
