Black Mercy is a plant that creates a dream of a person's perfect life by tapping into the pleasure centers of a person's brain. They are harvested by Mongul, and have been seen to be used on Hal Jordan, Oliver Queen, Clark Kent, Bruce Wayne, and even Mongul himself.
When someone discovers the Black Mercy-created reality is fake (they notice something wrong, or otherwise realize their lives aren't this perfect), the Black Mercy will slowly lose its grip on its host, making it easier to detach from them.
Superman: His father Jor-El's prediction was proven untrue. He is married to a composite of Lois Lane and Lana Lang, and has two children. In the midst of this, Krypton is going through a political upheaval; his cousin (who would be almost 16 years older than him now) is attacked by anti-Phantom Zone protesters.
Batman: In this dream, the murder of young Bruce's parents is foiled. He grows up and has a wife, Kathy Kane, and a daughter.
Green Lantern: Hal's father never died, nor did his mother, and his family is happy together. Hal is also dating his high school sweetheart Jen. Coast City was never destroyed; Sinestro never turned evil, and is his mentor and friend. They show the Green Lantern Corps fighting an unknown man possessed by Parallax.
Green Arrow: Ollie is married to Sandra Hawke and has a great relationship with his son, Connor Hawke (who is a hero at least similar to Speedy). He has at least three kids, and his identity is publicly known.
Unknown: He is Superman
Unknown: A family man
Unknown: Won the Lottery
The worlds are temporary, and people always break free, either from the plants losing their grip, or the people under its thrall realizing the nature of the charade.
- The Black Mercy plant appears in the Justice League Unlimited episode "For The Man Who Has Everything", which is based on the Superman Annual #11 story of the same name.
