I thought that one could strike with more power than they could lift because all the power is going into a brief impact with small surface area, but a physicist could prove me wrong.

I indeed thought you might have been scaling his strength to like a bug, which is what they did with Spiderman and spiders. His strength probably changes but I think he was 150 tons lifting. 

I'd be fine if he can lift like a forklift weight in andreemea. Our modern forklifts are lifting about 2 tons. Andreemea ones could technically reach extreme levels, but an average one would likely be around 10 tons. They'd antigravity thing to lift more, I'm sure. Can't check right now, but was he the type who could withstand explosions? It's all the things together that make me more picky on the individual stuff such as strength or else he's compatible to superheroes and seems almost unstoppable. 

Some individuals in andreemea could be like low level superheroes, admittedly. If people want us to be like an elite team then there wouldn't be an issue with his capabilities. Anyone care too much? I assume most people would want to be above average, so I'm prepared for that much.
