Concept: A female Soundwave, in the same vain as Slipstream, who is a female Starscream. Based it on Hatsune Miku, as at least on some image boards, she is his unofficial wife. Came up with the name Echotone, and her familiar is Chiptune, although she's the chest plate right now. Her tailfeather also doubles as the necktie. Considering the extent of the manipulation, I dunno if it could still transform. Still, I thought it looked good.
