At some point in time, a neighbour universe of Earth-19 started an invasion of this reality but it was repelled by this universe's forces. As a consequence of this war, it was created the Collector Agency, led by Breacher, and interdimensional travel on this reality was outlawed under penalty of death.
The Harrison Wells of Earth-19, H.R. Wells, became part of the S.T.A.R. Labs team, helping The Flash of this reality in defeating the villains. Some time later, a great conflicted erupted, dubbed World War M, which was a final showdown between the team and this reality's metahumans that were finally defeated.
In 2014, the infamous techno-wizard Abra Kadabra from an Earth-1 possible future was stuck in the past and started a quest to return to his time that led him to travel into the Multiverse. Arriving on Earth-19, he killed several Collectors like Gypsy's partner but managed to flee into another universe.
In 2016, Randolf Morgan cracked an invitation from Harry Wells of Earth-2 to find an Harrison Wells's doppleganger that would come to Earth-1 to be part of its Team Flash. H.R. Wells wanted to explore the Multiverse so he left his home universe for Earth-1.
In 2019, Gypsy was killed by the villain Echo, his ex-boyfriend Cisco's doppleganger. Unknowning that he lost his powers, the Collectors believed that Cisco was the murderder so Breacher came to Earth-1 to capture him; the Earth-1's hero managed to escape and, later, he found the real culprit and arrested him, honoring the memory of his dead ex-girlfriend..
When the Crisis erupted, this reality was destroyed when an anti-matter wave was unleashed upon it by the Anti-Monitor. After the Paragons rebooted the multiverse, Earth-19 was restored along with the other Earths of the multiverse.
