[DC] What are some of the Darkest Alternate Realities?
gpt
Personally, I’d say the two darkest alternate realities are Flashpoint and Injustice. 

Flashpoint includes the destruction of Western Europe, a hyper violent and murderous Batman, a war between the Atlantis and Themiscyra that is destroying the world, and a fearful and emaciated Superman who has never seen the sun. 

Injustice turned Superman into a murderous tyrant who killed many of his own friends and “saved” (read subjugated) the entire planet and murdering whom ever he deemed fit. His list includes green arrow, Shazam, a huge swath of the Green Lantern Corps, and countless others. The rest of the justice league either join him and become fascist and overall terrible versions of themselves, or joined a resistance lead by Batman and were generally captured or died.
