Rebooting the DCU
100 Years Ago: The Earth picks Century Children to protect the world. Doctor Axel Brass, Jenny Sparks, and The High are all born January 1st, 1900. On their 12 birthday, they become the first mysterymen.
JSA formed as a United States government sanctioned super team. Consisting of Axel Brass, Jenny Sparks, The High, Jay Garrick, Alan Scott, Carter Hall, Dinah Drake and Al Pratt. They would be the inspiration to the All Star Squadron and the Young All Stars
The JSA create a quantum computer that maps the multiverse. When they peered across the "Snowflake-like" structure, they realized another group was looking back at them. The JSA struck first and were stuck fighting in this "limbo-realm", staving off the Armageddon. Jenny Sparks is the only one left, waiting to guard the gate in case something else gets through.
1945-1955: The Age of Fawcett
Bulletman, Bulletgirl, Captain Marvel and most of the Fawcett characers emerge during this time to battle crime and to be "America's heroes"
1955-1965: The Age of the Justice Batallion
The Young All Stars come of age and become America's Premiere superhero team (Flying Fox, Iron Munro, Fury, etc). These are the Jack Kerouac heroes, fighting the Cold War and the weird wars on Route 66. They also have a darker contemporary group in Team One. This group (lead by the british Jenny Sparks) fights against the Daemonites who have already devastated Mars and is now settings its sights on Earth.
1965-1985: The Age of The Justice Experience
A new group of heroes, formed by Jenny Sparks after they fight off an parallel Earth excursion at Woodstock, NY, call themselves the Justice Experience. They become the heroes of the hippie movement. The government response to this team is called Team Two which is made up of the Charlton Heroes (Captain Atom, Dan Garrett-Blue Beetle, Nightshade, etc). This age ends with the "death" of Captain Atom who is tried for war crimes and sent into the quantum stream 15 years into the future.
1985-1995: The Age of Milestones
After a comet crashes into Earth, it interacts with a mutagenetic chemical and creates the Big Bang in Dakota City. This big bang gives way to new superheroes known as Bang Babies that become the premiere superheroes and supervillians of this age. The first heroes to emerge in this era is Icon and Rocket. These heroes are ethnically diverse and powerful, but are eventually taken down, one by one, by the group known as the Shadow Cabinet. The only heroes that fight back against the Shadow Cabinet is the government group known as Stormwatch, which becomes the premiere superhero team after they defeat the Shadow Cabinet and free the SC's captive heroes and villains.
1995-2005: The Age of Wildstorms
The Wildstorm era begins with the emergence of the WildCATs (a corporate sponsored team) and Stormwatch (a government sponsored team) coming to blows while fighting off an alien invasion. Stormwatch evolves into a variety of different groups and creates a variety of different superheroes (as in the Gen 13 project or recovering the JSA from an alternate dimension) while the Wildcats recruits more heroes to stave off alien invasions from the Daemonites and the Drahn. This culminates into Jenny Sparks, Axel Brass, and The High sacrificing their lives at the end of 2000 for the sake of humanity. After 2001, many of the teams disband or are cut back due to government cuts. Stormwatch Crime Units (SCU) become standard groups in different Law Enforcement Agencies in big cities. Many of the WildCATs go back to help rebuild Khera.
