Armstrong (MGRR) vs. Claymoreverse

People have a misconception of Armstrong Powers, The nano shield only serves as protection to High Frecuency Blades, he doesnt need it for other type of attacks, and even so, you need the Murasama to hurt him, anyone who doesnt have it is pretty much screwed.
He doesnt need the shielding to tank extreme blunt force, he was overpowering Raiden and taking a full force punch in the face without the shields in the last fight.

Armstrong speed, he was capable going through the arena fight pretty quickly with his dash attacks, he even has a meteor-like Kaio Ken type attack in the Sam Scenario

TBH Armstrong doesn't seem to be any stronger than Raiden is. Raiden was clearly able to match his strength when he they locked arms. Armstrong was only dominating the fight because Raiden couldn't hurt him as oppose to Armstrong doing damage to Raiden.

As far his speed goes, Armstrong seems to be able to dash and run fast but his combat reflexes, his ability to dodge seems sub par at best.

One-shoting Metal Gear Excelsus with a single punch puts him well above Raiden.

Raiden already destroyed most of Excelsus. Armstrong basically destroyed a giant empty hull.

Excelsus minus the giants blades was intact, he still made the whole thing explode

And probably several hundred tons of armored plating that Raiden lobbed off.

But fair enough, it seemed after that Armstrong is indeed stronger and more durable.
