well remember that he has been trianning since he was like 7 and he is in his 40’s so him lifting that rock isn’t surprising, but i bet it only weights like 500 pounds and he is using it as an endurance trianning. now if it was 10 or 15 tons then that can’t be ryu, that would be like…akuma or oro since they are like the only ones with that kind of arm power.
i bet ryu is just a really advanced human as far as phycial power, but he ain’t like a “demon” such as akuma, or a senjin such as oro.
a senjin is an old master of an old art, thats what akuma, and ibuki call oro in sf3 3s, but yeah i guess it’s huge. but i doubt we will ever see ryu, destorying any asteriods.
