Yep Apoc has a lot more than just physical force. Remember how easily he killed those workers Eric wanted to kill? I didn't see any physical force involved there IIRC.
It was because of Xavier's power that Shaw was easily killed by Erik, And remember, Charles was young and fairly untrained compared to his current and future iterations at that time. It wasn't until DOFP that Xavier got over a huge limitation of himself.
Ummm.... Not without the helmet he's not. Apoc is actually the better TP guy when fighting individual targets. Only Phoenix beats him out, because in the Psionic plane, Apoc was royally pushing in Xavier's shit.
How? Shaw wasn't that strong, psyonically, and he had some training from Emma frost, but he had no psychic abilities of his own.
And, how do you come to that conclusion? Shaw's goal was basically the same as Erik's became later, the rule of mutants. En Saban Nur is the Rule of the Strong. Mutant, human, or otherwise. Only the strong would find a way to survive Apocalypse. And, since Apoc had powers Shaw would onnly be able to wet dream about, he had the capacity of carrying out his threat without starting a war. Apoc was going to wipe the slate clean without sparking WW3.
Not denying that at the time, Shaw probably was among the strongest Xavier ever tried to freeze. But, at the same time, Xavier was younger, less experienced and not as confident of his power back then.
Then, you have the lines he spoke when Apoc jacked him through Erik and Cerebro.
"I have never felt a power like this before!" he said as he looked like he was simultaneously pissing himself and having a heart attack.
Who was far weaker in the 1st movie. He's extremely more powerful now as in the movie it took everything he had to hold 2 guys still. In Apocalypse he froze at least an entire floor of the CIA quite casually.
But he did to an extent. He only lost control of them during the exchange when he was completely distracted. he was fending of no less than 5 full on assaults, which became 6, and 2 of them took place on the psionic plane. Kinda hard for anyone to expect someone of Apoc's telepathy, which is singularly focust, to maintain control during a TP onslaught by 2 of the series most powerful Telepaths.
The fact that Shaw was frozen at all by Xavier, while Apoc was resoundingly mentally beating the shit out of an older, wiser, more experienced, and more powerful version of the same dude instantly tells me who would win in a clash of the minds between Shaw and Apoc.
