War of the Negative Forces (Earth-Prime)

"See, this is on you, Flash. You tipped the scales. We're just puttin' things back to normal, and-and-and then some. This all started the day that you severed Thawne's speed... The day that you upset the cosmic balance. Something we didn't know was possible until you showed us how. And that was also the day that we realized... we could do the same. Time to tip the scales."

- Deon Owens to The Flash

The War of the Negative Forces was the Negative Forces of Nature's attempt to tip the cosmic balance by eliminating the Forces of Nature from existence.
