Earth-2

Earth Two is a world parallel to Earth One. The name was coined by Martin Stein. It is Earth One to its citizens.

History
A conflict called the War of the Americas happened sometime during the 20th Century. Jay Garrick's father fought in it.

Sometime on a voyage, Oliver Queen and Robert Queen were involved in a violent shipwreck which took the life of the former. Robert eventually made his way back home and became the vigilante known as "The Hood" and later "The Arrow".

In 2013, the particle accelerator from S.T.A.R Labs exploded, giving many civilians including Jay Garrick special powers. This prompted S.T.A.R. Labs of its studies in meta-humans. Various meta-humans such as Atom-Smasher, Sand Demon and Doctor Light became corrupt with their powers and became criminals. Sometime after Jay Garrick became the Flash, Zoom showed up, the two became enemies and have been hunting each other down ever since.

On May 19, 2015, a singularity breached the world, originating from Earth One. As a result, Jay Garrick was sucked through. Zoom discovered how to cross the dimensions, and brought meta-humans between the worlds to assist him in his mission to kill the Flash.

Trivia

 * Although comparable events on Earth One and Earth-2 seem to happen roughly at the same time, there might be a global shift of the timelines with respect to each, as evidenced by the fact that Harrison Wells founded S.T.A.R. Labs in 1991 on Earth-2 while his counterpart from Earth One (as well as Eobard Thawne in the altered timeline) founded S.T.A.R. Labs at the earliest in the year 2000. This apparent mismatch of events on the two Earths might be explained by the nature of the singularity and the breaches, connecting Earth One and Earth-2, possibly representing a gateway through both space and time. However, if the timeline of Earth-2 was really somewhat ahead of schedule with reference to Earth One, it could explain why Harrison Wells of Earth-2 could start the particle accelerator already in 2013 (possibly without the help of Tess Morgan), while his counterpart from Earth One accomplished that goal as late as 2020.
 * This version Earth-2 seems to be an amalgam of Earths 2 and 3 from DC mythology. It features villainous versions of heroes or civilians from Earth 1, (Linda and Al Rothstein) similar to Earth-3, but features the same heroes from Earth 1, but with different civilian identities than those of Earth 1, (Jay instead of Barry; Robert instead of Oliver) such as on Earth-2.
 * Stylistically Earth-2's Central City has a late 40s-50s aesthetic, presumably as a reference to the real world 1940s and 1950s (also known as the Golden Age of Comics). During this time The Flash character was first created, with Jay Garrick as his first civilian identity.
 * Television and computer screens on Earth Two are vertically rectangular rather than horizontally.
