Optimus Prime's Battles in the Unicron Trilogy
There were three times Optimus Prime DID NOT PERISH completely (but he did temporarily die in Armada perhaps as a reference to the movie) but he came back to kick Galvatron's ass. I can say all these battles are interesting as the Unicron Trilogy Megatron/Galvatron is not the utterly insane one but a rather, scheming and calculating villain.
This is the battle in Transfomers Armada right inside Unicron.
An MV without character vocals but enjoy...
Did it take too long to finally end the emperor of destruction? Regardless it's an awesome battle as it should have been!
