I'm glad you like! She is very adorable. A skilled and efficient warrior, but very, very naive. (Consider the odd circumstances of her awakening, and what her age must be. Of course she clings to Megatron like she does, poor thing.)

And no, Megatron certainly wouldn't let her odd anatomy get in his way. He cares about the power, not the details.

He might find the details a bit odd or even distasteful if he sat down and thought about them, but he still wouldn't care much even if he did. He may get off hardest on SS' brattiness, but he also really enjoys (and needs) whole-sparked (or whatevered...) devotion every so often.
