Over at TFW they are linking to a post by TF-prototype about a black recolored Generations Arcee. The site is saying that it's a Botcon sneak peak. Colouring reminds me of the MMC Stealth Assasin Azalea. The colour scheme is also reminiscent of a cover of a Combiner Wars comic as per the post and pic.
