On Earth-A, the first titans (i.e. superheroes) emerged shortly before The Great War (World War One). The first to emerge was Athena in 1912, followed by the first Cosmic Custodian in 1914. Thanks to the efforts of the titan community the war ended in 1917. Due to pressure from titans, the War Guilt clauses were removed from the Treaty of Versailles. The subsequent economic stability of the new German Realm stifled the attempts of the Nazi party to take root. The Second World War as we know it never occurred; Instead, the USSR invaded Poland in 1931, triggering The Second Great War. The war ended by 1939, though with a massive loss of life that even affected the ranks of the titans, claiming the lives of the first Scarlet Stalker & the Cosmic Custodian. With the USSR in tatters, desperately trying to resist neo-tsarist forces, the Cold War never occurred. As a result of the Nazi party never seizing power, technology has developed much more slowly than normal, with Earth-A being about 20 years behind our present technology levels.
