The big battle that closes out the World Split manages to be both incredibly chaotic and incredibly awesome.
After a year of separation this Warner Chain is. Just. Awesome.
When Trevor kidnaps Aisling, she manages to call for help using Trevor's own communicator. While he attempts damage control via Implausible Deniability, nobody buys it... least of all Optimus Prime.
Shortly afterward, Trevor tries to lay aMind Screw on Starscream and Soundwave by claiming to know more about the ink than they do. Starscream completely shoots down his theories, and when Trevor tries to one-up him by acting like he nearly took out Prime and merely 'spared him for the sake of future research', Soundwave replays a recording of what REALLY happened. Getting repeatedly called on his lies is enough to force Trevor into a minor Villainous Breakdown.
Legato and Tai Lung meet. Practically the first thing they do upon meeting? Have a match that wouldn't be out of place in KFP itself (or Dragonball Z), that both of them considered a spar. Bonus points for neither of them actually landing a hit on the other.
