Megatron and Optimus Primal in “Master of the House”

I am the future. I have forged this entire planet into a single elegant machine. A vision of technological purity and order. And you four mongrels would dare contaminate that vision with your accursed beast modes!

My memory's a little faulty, Megatron, but I seem to recall you picking up a beast mode yourself.

I wiped it clean from my shell! Like a virus! The same way I wiped this planet clean! The same way I intend to finish the job with you!
