Strika
Quote: "Vy do you keep asking if I'm Arcee?"

Ms. Blu never had anything on Strika...  Skrika is an ancient defender of Cybertron... Aligned with Megatron only because Megatron *is* Cybertron at the moment.  Strika also has an annoying, Eastern European accent.  It would make sense if Obsidian had one too... but since he doesn't , we just have to assume that it's some bizarre fixation of Strika's.
