Overview:

Superpowers were unheard of until early 1942 when an Allied commando team raided a secret Nazi laboratory. They destroyed the lab, but they were exposed to a mutagen. Apparently it was virulent for it to spread to a flight crew and to certain individuals near their base.

Axis was shown to have some supers in the upcoming months.

On Oct 14, 1942 a large explosion happened over the city of Stalingrad. Immediately afterward the number of supers increased with a large concentration near the explosion. The ones closer to the source were generally more powerful, but also stranger. However the number of supers increased all over the world.

The eastern front was a meat grinder for both the Germans and the Russians. During this time the US & Britain were able to build up significant forces.

Africa was invaded much as in the real world in late 1942. The Tunisia campaign was helped by a quick capture of the Axis team with the German army command.

Italy was invaded in March 1943, Normandy in July 1943.

During this time, the Allied team was split into Pacific and European strike forces, while most important leaders had at least one meta as a guard.

On April 5, 1944 a climatic battle near Moscow finished what remained of the Axis forces. Both the European & Pacific teams were brought to the battle by Hell Girl, a german operative that turned. While the details are still classified, there had been a plot to detonate some sort of super bomb. While the full effects were neutralized, a barrier was put into place by the device 100 miles in radius and three miles high. Most of the Allied team was able to escape, but US Steel, Himavan, and Hour Man were caught behind. Also caught in the dome were most of the Russian and German supers along with many of the conventional forces. This dome is still there today.

The Axis supers that remained outside the dome were no match for the Allied supers. Hitler and his staff were captured April 28, 1944. Germany surrendered unconditionally March 3, 1944. Hitler, Goebbels, Goring, some others executed. Most of leadership imprisoned in November 1948. Some released in later years.

Japan surrendered January 17, 1945. The blockade of all shipping is credited to this. The hero, Torpedo Joe, and the US submarine core kept any supplies from reaching Japan. While this happened the Pacific meta team was able to take out island fortifications. While not to disparage the effort of the other heroes, most people feel that Pele' was the most effective force in this endeavor.

June 3, 1945 saw the first meeting of the United Nations. While the armed forces of the member nations were separate, supers were placed under the special control of the United Nations Super Hero Branch. Until 1980, this branch was headed by Nigel Ashe, known during the war as "Major Radar".

Demographics:
For some reason the US has a higher proportion of supers than anywhere else.
The supers that showed up since WWII seem to be less powerful on average, but more varied. WWII had very few flyers, Two teleporters, No traditional mentalists. Since then, there are more flyers, a few more teleporters, but mentalists are still very rare.

Some of the surviving active heroes from WWII:
Britannia
UK; Super strong and resistant. Has a hammer she claimed from Thor in the battle at the Dome. Unknown location from May 1945-49. Does not discuss disappearance, but changed appearance and seems very proficient with hammer. Stays away from politics. Has not visibly aged since WWII.
Dex
US; Reported KIA 1943, reappeared in 1955. Has super gadgets. No one knows where the gadgets come from but they disappear when out of contact with Dex. Also has relationship with computer AI that existed in WWII. AI claims to have been built by Dex's father. Seems to age slowly.
Apex
US; Highly trained super soldier. Thought to of been from the experiments that brought about Germany's Ubermensch. Apex did not have the drug therapy that Ubermensch had, so does not have the extra powers. The theory is that this therapy is what led to Ubermensch's and several other super's deaths in the late 1940s. Instead, Apex looks to be in his early 30s.
