I honestly have no scans, and didn't see any on the forum either. Galvatron can ceratinly blow up a planet, as can Megatron (admittedly depending on the size)
Tyrant can win this if he is able to drain energy fast enough, but Fortress Maximus and Omega Supreme are incrediably strong, I mean basically Omega takes on 20 decepticons regularly. His mission is to be the last one standing. I can't remember too many FM fights, but he is basially the most respected guy in the autobots. Then you have all their leaders, and the Dino-bots. I mean their weapons could arguable be effective (I am not sure if a energy bland would cut Tyrany or if he would drain it) but the dinos could literally eat Tyrant.
