This is the story of Kal-El. The Last son of Krypton who crash landed on Earth, but not the one we are all used to. Instead Kal El crash lands in the MCU. This is the story of Kal-El the boy who even in a universe of Marvels, filled with; billionaires in suits of armor, super soldiers, Norse gods, spies and monsters becomes the greatest hero on Earth... Superman. This story is NOT mine.
