Just... something that I feel as a possible change to history with the knowledge that we currently have of the background of the world. Feel free to reject it if you desire, just putting it out there for discussion... 

During the First World War, while Russia's military was largely a mess it found itself with an abnormally large amount of supers to draw upon due to the massive amount of people it could call up for military service. This gave the Russians a leg up on the Germans and the Austro-Hungarians who had to divided their supers between their eastern and western fronts, allowing Russia to make up for some of its armies short comings and start off the war better then it did in our reality... However, the poor logistics and questionable leadership of the Russian Army plagued the war effort like normal. 

While Supers started off as being held in high esteem by the Russian people, when word started to spread that Rasputin himself was a Super of some kind (Rumor couldn't exactly agree on what powers he might have had, but mind control was a strong candidate) a number of people at all levels of society started to develop a degree of hatred for supers... which would be later used by the raising Soviet movement to stir up unrest and start their revolution. After all, how could people be equal and given the same opportunities when this so called 'Supers' existed? 

The resulting civil war between the White and Red armies would be more interesting due to the lack of supers used by the Red army... while the White armies could deploy Supers in the field. Regardless of victor it would be the end of Russia's involvement in the First World War, but it is fully possible that in our Timeline the Soviet Union didn't exist because it lost to the White armies in the civil war due to the presence of Supers.

Course the Soviet Union could also be around... it depends on if we wish to consider what Russia would be like now if the Soviet's lost in the early days of their revolution due to Supers in the White armies.
