I do not own the Metroid series. Nintendo does. I only own this story. Enjoy!
Location: A lab at Federation HQ, Earth
Two Federation scientists were working on a rather ambitious project for their superiors. "What is this project?" you may ask. Well, after the bounty hunter Samus Aran destroyed the BSL (Biologic Space Laboratories) Research Station, it was the final straw and thus the Galactic Federation deemed her an outlaw. When devising ways to bring her in, they came up with an idea. Create clones of Samus to match her and subdue her as a result, bringing her back to HQ to be tried for her crimes against the Federation. A few individuals within the Federation, such as Admiral Castor Dane and Anthony Higgs, spoke out against the idea. They were promptly stripped of their respective statuses and then imprisoned. With all of the opposition dealt with, they charged these two scientists with the task of creating these clones.
Which brings us back to the present scene. The two scientists were looking at their handiwork and were quite proud. By now, the clones were about finished and were soon to be awakened. The one on the scientists' right looked like Samus' doppelganger, minus her slightly pale skin and black hair. The one on the left, however, looked like a much younger version of Samus, also with slightly pale skin and with green hair. Their resemblance to Samus is easily explained, as they were both created from Samus' DNA. However, despite their appearance, they are not normal humans. Along with the human and Chozo DNA received from Samus, they also have Metroid DNA. You see, the clone on the right was created from what was left of Dark Samus, taken off of Samus' PED (Phazon Enhancement Device). While the clone on the left was created from what was left of the Super Metroid, the one that imprinted on Samus and ended up giving its life to help her defeat Mother Brain once and for all. These samples were taken off of Samus' Varia Suit, much like the ones used to create the Metroid clones on the Bottle Ship and BSL Station and the Metroid vaccine that saved Samus' life when an X Parasite infected her. The samples from both Dark Samus and the Super Metroid were then combined with Samus' DNA to create the clones. The scientists were hoping that the clones would be obedient and not turn on them like some of the other Federation creations have before them, like their clone of the Space Pirate Ridley and MB, an android version of Mother Brain created to control the Metroid clones. The scientists were sure they would follow the Federation's orders and bring Samus to them.
However, what the scientists didn't realize is that while the clones have the abilities of their counterparts, they also have their consciousness and were using telepathy to not only get to know each other, but also to plan their escape.
