Earth-15 was one of the many universes in the multiverse. For unspecified reasons in 1986, its Earth was destroyed and was considered a dead Earth.

History

A dead world

In 1986, Earth was destroyed and became a wasteland.

Earth-1's waste disposal

In early 2018, Cisco Ramon vibed all of Neil Borman/Fallout's nuclear radiation to this Earth.

A couple months later, Cisco suggested breaching a nuclear bomb threatening to explode in Central City to Earth-15 before it detonated. However, because Team Flash was forced to operate in Flashtime to stop the nuke, this proved impossible as Cisco was ill-equipped to open breaches while moving at such high speeds.

Over a year later when Team Flash needed to stop a virus made from the meta-human cure, Barry Allen suggested taking the virus to Earth-15.

Anti-Monitor Crisis

On December 10, 2019 during the Anti-Monitor Crisis, whatever was left after the 1986 disaster was destroyed by the antimatter wave along with the rest of the Multiverse.
