LadyAwesome45321: They are, and they probably wouldn't cross paths; these one-shots all stand apart from each other and take place in their own alternate universes (though their reunion would be violent). Thanks for the review!
Cyborg
Losing body parts, however small or big, is never fun nor ideal. Especially not for Ray Palmer – he lost his right leg, left arm and a huge chunk of his left shoulder that day. It would not be an understatement to claim he was dying from pain and blood loss. The blast, unfortunately, had knocked him out cold, so that was a comfort. The Legends could not help him; the French had taken the Waverider and they were deep behind enemy lines.
They were fortunate enough to find a doctor who wanted to help. They left Nate with Ray while they left to retrieve the Waverider. They wouldn't be back soon.
When Ray came to, Nate broke the news to him: he had lost some limbs and the doctor kept him alive until they found a mechanic to help him with prosthetics. They were stranded on the future border of Germany, occupied by the French (they started the war) who fought primarily cyborg warfare. Ray now lived with a robotic arm, shoulder, and leg.
It took him a while to get used to, and he started to think of all the possibilities his prosthetic limbs. His suit had been too damaged to salvage, and now he had a way to fight back regardless. Even after leaving this time period, Ray didn't want to replace the metallic with human flesh right away. He could always replace it, but for now, he wanted to keep his new limbs.
He tinkered away, adapting the limbs to fit his needs and to build in some of his on tech. It became a pet project, which he continued after retiring as a Legend. All went well, but Ray became violently ill. Nate had forgotten to tell him the prosthetics were a temporary solution; that they would eventually attack the host, the metal alloy forcing itself deeper and deeper - an unfortunate side-effect if this incredibly sentient technology. With no way to contact the Legends and not accepting he needed any help, he set out to fix himself on his own.
The result was disturbing. Helped by the time pressure, he found a way to upload his consciousness into a new suit of armor, hollow and designed to be worn by a person. The body was indeed trapped inside, but the mind controlled the suit as if the suit were his body. His former face was pale and neither mouth nor eyes moved. The body itself was braindead – Ray could see through the suit's visor, and all other senses had been replaced by sensors. Taste and smell were no longer relevant, and he did not need to sleep anymore. He could speak, but the suit's vocabulary was limited to the noises it could produce.
Within ten years, he had built robots that shared similarities with his previous suit. But they were better, and Ray uploaded his consciousness from the suit into his best robot. Once again, he was capable of making smoother movements and could say what he wanted to say more freely. He had no reason to keep the body and buried it somewhere. He was happy with the results, even if his former friends weren't.
Ray opposed their idea of building him a new flesh body on the Waverider. He had been doomed to this fate since he set foot in that particular future, and now he was going to live up to the mistakes he made. If all went well, the past ten years may be erased in favor of a better future.
Ray waited patiently for the right moment to strike Europe with his robots, controlled by hive-mind. He had the French construct more of his suits and attacked Germany, which focused on replacing lost limbs with advanced prosthetics.
But the war and his life as a mere consciousness had changed him. the Legends did not recognize him anymore, and neither would the old Ray if he had been there to see it. He was many and one, and he was going to conquer Europe (and especially Germany) if it was the last thing he did. He even made sure the younger him sustained the injuries that brought him on this path.
Ray survived the wars to come, and they brought not only Europe but the entire world to its knees. He'd craved power since Germany pushed back and tried to deny him said power. Their robots are currently mass-produced on every continent and they rule supreme, everywhere at the same time. Their delusions of grandeur grow each day and they have not felt human emotions in a long time. One day, they might even decide humanity isn't worth keeping around anymore.
