[@Savato] you're absolutely right, I'll quickly add in his physical abilities. Really, I'd compare his physical attibutes to Wolverine "Kinda strong, has a weapon that'll cut through damn near anything and is almost impossible to put down and make him stay down."

I mean, looking at the physical attributes for a Primarch, I'd say that, at max, he is only able to lift about 10 tons over his head... Yes, that's a lot... But then you realize that that means his strength is equal to that of Spider-man... I mean, he's not a Gargantuan creature or a Super-Heavy walker. I imagine that a Carnifex is about the biggest thing he'd be able to pick up and throw, but that's only about 10-20 tons, which, again, is dwarfed by certain Marvel superheroes that aren't really known for their physical strength, like Venom, Nova and Vision.

Their main strength is that, unlike those characters, every bit of this strength is translated into their swings. I mean, Venom obviously doesn't punch at 40 tons of strength, he'd shatter the skeleton of ANYONE he punched. Angron, however, can and will swing that axe with 10 tons of force.
