Megatron wouldn't survive in Terminator Salvation?

Me and my friends just recently watched Terminator Salvation and Transformers 2 because they've premiered on HBO this year. We didnt go to the movies to see either movie, so these HBO premiers are like brand new movies to us. And while watching Terminator, my friend had to the nerve to tell me that Megatron wouldn't make it in the post-Judgment Day Terminator world ran by the machines. He said Megatron would be some chump who gets punked out by Terminator machines. I personally think that Megatron could walk up to any Terminator he wants, smack him, and walk away unharmed. How dare someone say that Megatron would be scared of some punk azz Terminators? Or that he cant smack a Terminator? Do you believe the shyt he was saying?
