I got the Legacy core class G2 Megatron for christmas, so I figured I'd showcase it in a battle with Core Optimus. To those who don't know, the first G2 optimus prime toy (which was released around the time the original G2 Megatron was) was just the G2 Optimus with a black trailer instead of grey, so the pairing is pretty much perfect.

That said, I have only two words left to say...

"MEGATRON ATTACK!"
