the power Vision has - the power to control your density:

“This can increase his strength and resistance to injury dramatically, making his skin and muscle comparable to the hardness of a diamond and denser than uranium. At full power and density, he can press roughly 50 tons. Likewise, he can shift his density in such a way that he can achieve flight, or make himself completely intangible, able to phase through solid matter without disturbing it.”

it’s no wonder MCU killed him off in Infinity War since - given the actual chance - Vision would’ve wiped the floor with Thanos
