Picking up on plot threads from Superman Returns, the story postulates that the crystal continent Superman threw into space has become a near-perfect sphere dubbed New Krypton, which is visible from earth like the moon. This satellite draws in the attention of another apparent survivor from Krypton, who is befriended by Superman and ultimately "replaces" him in the hearts of the people because he has introduced advanced technology, despite the Man of Steel's insistance he not interfere with human development.
Not surprisingly, things aren't as they appear to be.

"Superman starts getting a bit suspicious of Krypto buddy and decides to go talk to him," offers the article. "He goes to his spaceship and has a revelation. This massive ship is full of hundreds if not thousands of identical bodies aboard, yep, clones of Krypto buddy, in stasis. So Superman digs a bit more inside the computer system, which is familiar to him since it's Kryptonian technology just like the Fortress of Solitude. Superman finds out that Krypto buddy is actually an artificial intelligence from Krypton that has evolved since the destruction of their world. He escaped Krypton just like Kal-El did and his real name is Brainiac. He has been going from planet to planet, taking their technology, helping these worlds reach a relative perfection and then he destroys them and moves on.
"Superman also finds out that he was actually responsible for the destruction of Krypton and tries to warn the leaders of the world but is confronted by Braniac. A massive battle ensues and Superman is about to defeat his foe but right just before Brainiac downloads his conscience into one oh his other clones. Superman realizes that he must destroy this massive ship along with all the clones aboard. After another massive battle he is able to disable the ship, destroy the clones and the new Braniac but right before the ship is destroyed the Braniac main frame does a local search for another body that he could download in to, it has to be Kryptonian, and he finds another one on Earth, Superman's kid, Jason White.
"So Brainiac uses Kryptonian technology and beams/download itself into Jason's body and this causes causes him to age and grow into a full adult but with Brainiac in complete control. Superman realizes what just happened and rushes to confront his very own son who is now possessed by Brainiac. Is Jason still there or is it all Brainiac? It's all Braniac and Superman knows what he has to do, he must defeat Brainiac at all costs or the planet and it's inhabitants will be doomed.... There is a Christ like metaphor here. Superman has to sacrifice his own son to save humanity."
Voices From Krypton's response: This feels more like a fan-fic than a scenario for a potential Bryan Singer film. Brainiac entering the body of Superman's kid, and that body then aging so that father goes up against son...and then KILLING his son? This just doesn't sound credible. What do you think? Are we being too harsh?
