The year was 2789, Equestria had achieved an amazing level of technological advances, new sustainable energy sources were developed, cures for diseases were discovered and introduced to medicine, New ways of transportation had been constructed and War between diferent had come to peaceful solutions.
But there was still one threat that with the advance of science everyone had forgotten about the changelings, Chrysalis had tried many times to take control of Equestria, each attempt had been stoped by the mane 6 and its friends, and by the time she had made her last attempt, madnesss took over her mind and she searched trough the history of the changeling to see if there was any other way that could overcome the magical power of friendship.
Unfortunately she found one, the changelings had relationships with an alien race of ponyoid beings called Xenozians, this race had an extraordinary culture dedicated to militarism, their weapons and soldiers were exceptional among the other alien armies in the whole solar system, Chrysalis desperately for the help of the Xenozians used a spell to send a beacon to the cosmos to call their old allied race, the call was answered after a week the spell was casted.
The leader of the Xenozians Zyghar II recognized the proof of the historical relationships the changelings had with them, and the Queen of Changelings and the Hykien (Hykien=king) of the Xenozians agreed to help each other on the campaign of taking control of Equestria, the Xenozians with their superior technology and training combined with the combat expertise of the changelings formed an strong army, the one that ever set foot on equestria if not.
In October of the same year, the atacks of the changeling-Xenozian army started, the first city to fall was Ponyville, with ease they crushed the royal army of the two sisters and captured the princess of friendship and the representants of the elements of harmony, the other city to be victim of the mighty alien changeling army was Canterlot, yet again the royal army was defeated only this time their brutal firepower managed to capture the two princesses and so with those two important targets at the control of the evil army of Zyghar and Chrysalis they started to attack the rest of the cities of equestria and the last target was the one that Chrysalis wanted since from the beginning, The Crystal Empire, after 3 weeks of battle the Empire of princess Cadance had fallen to the mighty Xenozian-Changeling army and again the princess of the target had been captured.
Chrysalis with all the princesses and the elements of hamrony harmony at her hooves saw an opportunity to become even more powerfull without sucking love from ponies she ordered to the Xenozians build an machine capable of draining magic to tranfer to her, a few months later the machine was built and the magic of the rulers of equestria and the elements of harmony had been drained, making Chrysalis the most powerfull being alive on Equestria.
With the control of equestria being at the hooves of Zyghar and Chrysalis, the royal army had been pushed to the allied kingdom of Lunaria, there the last remaining scientists of the royal army had been cornered to an drastic solution, they came to the idea of building super soldiers that had amazong combat abilities and that at the same time could be an platform of using heavy weaoons, the result of this idea was the production of robotic super ponies called "Proboponies" the thing that made them special was that not only they were war machines but they had the hability to think, to feel emotions, this was amazing but at the same time it saddned the scientists, seeing for the first time sentient robots being used for war and not for peacefull purposes…but thats not our story is going to tell, our story will be about the first probopony team created and their leader Probotector as they fight against the changelings, will they bs able to rescue the princesses amd the elements of harmony and defeat chrysalis? Well only time and the acitons of Probotector have the answer to this question
