And the Transformers would get much less screen time and dialogue. Most of it would be focused onhumans^'Muricans! Autobot City would be a big NEST base, and it'd mostly be US soldiers (with a small handful of UK soldiers as a token "international" minority) fighting the Decepticons, most of whom we wouldn't recognise in a pink fit, and the Autobots would be the Americans' sidekicks. Hoo-rah! Oh, and when Optimus Prime lifts off as he transforms to robot mode and spins in the air shooting Decepticons -- before he lands he'll get tangled up and spend the next twenty minutes being upside down before getting to Megatron. Devastator would come in like a pair of wrecking balls, and we would see at least one of the following actions from the Transformers:
+ lewd acts
+ urinating
+ farting
...and this would happen during really crucial moments too. "Springer <farts>, you and Arcee transform Autobot city. Perceptor, stop lubricating on that man and tell Blaster to radio Prime for reinforcements. Blurr..." <lewd.act> "...never mind."
Oh, and instead of becoming Galvatron, Megatron would be restored as... Megatron! Oh, and Daniel would be a good 8-10 years older, and naturally his mundane life would become a focal point of the story. And in the ending credits, Cyclonus would be called "Pointy," and in the actual film, Blaster would be called "Billy."
