I was watching Starscream' Brigade last night and decided that I love the sound of Welker's Megatron voice. It got me thinking, which episode of G1 has the most Megatron talking in it?
I rather enjoyed the two Stars Brigade episode for its focus on the Decepticons, and let's face it, in my extremely un-scientifically gathered evidence, the Autobots get a lot more screen time than the Decepticons.

So, what should I watch for the most efficient consumption of Megatron voice-i-ness?
