This is probably something that'll happen in the last season of Aniamted if it ever comes to that...which i want it a long time away from now.
BA is severly damaged in battle and the only way to save her to purge her organic half and (like the Crossing the rubicons, Megatron attacks the base to rid of Blackarchinda(whom Megatron considers a traitor) and coems back as Elita1 and the decepticons retreat as always and yeah.
