Fan Casting Brainiac in The Man of Steel Universe (DCEU)

A sentient being that with the help of retconing some events of Man of Steel, has Argo City in his collection. He is a knowledge seeker and possible android turned sentient life. He collects parts of worlds such as Krypton and tries to invade Earth for his collection. I would like to see his life process on screen through hundreds of thousands of years. To see his original design to his look of nowadays.
