Supergirl Season 1 Episode 13: For the Girl Who Has Everything
The Black Mercy was created by Alan Moore and Dave Gibbons. It debuted in Superman Annual #11 (1985) with the story called For the Man Who Has Everything. In the original story Batman, Robin and Wonder Woman go to the Fortress of Solitude to celebrate Superman’s birthday. They find the Black Mercy attached to him. Mongul comes out and takes the credit. As Wonder Woman fights Mongul, Batman and Robin try to free Superman from the Black Mercy. They free Superman, only to have Batman under its influence. Robin ultimately frees Batman. Superman almost loses himself to the point of almost killing Mongul. Robin puts the Black Mercy on Mongul thus defeating him.
This story is considered one of the greatest Superman stories ever told. As like the Supergirl episode, the Black Mercy gives its victim a full sensory illusion of what their heart most desires. In the case of Superman and Supergirl, it is a Krypton that was not destroyed. For Batman, it was a world here his father was able to defeat Joe Chill before Chill could kill him or Martha Wayne. For Mongul, it was him killing all the heroes and conquering the universe. Like in the show the plant loses grip if the host realizes the fantasy world is not real.

Earth 2 Barry’s phone list is interesting; the names Bruce, Diana, Hal and Eddie are on his speed dial. One would assume that Bruce is Bruce Wayne (Batman), Diana is Diana Prince/ Diana of Themyscira/ Princess Diana (Wonder Woman), Hal is Hal Jordan (Green Lantern), and that Eddie might be Eddie Thawne. That is just an idea.
