Wonder how to make megatron fit in the Code Geass World. I mean having a transformer waking around isn't going to be very stealthy.

He doesn't care about stealth. Anyone who gets in his way, dies. Therefore, no witnesses.

Or I could have him Scan a tank from that world
(and by the way, his riot cannon is strong enough to take down a building)
