What was YOUR first Optimus Prime? Do you still have him? Any headcanons?

Mine's this little guy, TFP Cyberverse Nightwatch Optimus.

At first I thought of him as an RBxTFP Optimus, since it has some RB OP elements like wheels on the arms, yellow eyes and lights above the windshield. His nemesis was activators Lockdown, but I don't know where he went (I guess Optimus won).
