"The MCU version of The Vision is pretty much the most powerful character shown on-screen to date.
His body was co-designed by Ultron, whose knowledge of robotics probably exceeds Stark, and Dr. Helen Cho, a woman with such thorough knowledge of human biology that she can heal normally fatal wounds. Other than the Infinity Stones, his body is the single most complex arrangement of matter in the nine realms. He is composed of vibranium in a way that mimics human biology, without sacrificing any of the metal's renowned invulnerability. As if that's not enough power as is, he has seemingly flawless control of his own molecular structure, capable of generating a cape in seconds and altering his body's density. He can phase through solid matter and become dense enough to take multiple hits from Ultron without taking any damage.
Even with his noteworthy physical strength, the Vision's true power is his mental fortitude. Because of the Mind Stone embedded in his forehead, he can see into the past and future, read minds, observe and reverse-engineer technology from other dimensions, has a peerless knowledge of human genetics, robotics, mutation, weaponry, and vehicles as well as use mind control on other beings. The Stone also serves as his power supply and he can fire high-energy lasers through it."
