Notably, this is not the first or only time Superman has worn a black suit in the Arrowverse - sort of. It will, however, appear in Zack Snyder's Justice League, as revealed by posters and other key art. The suit was originally intended to appear in 2017's Justice League, but was scrapped from that film. Additionally, it offers increased protection to the wearer. It was intended to heal Superman should he suffer a grievous injury, as it was built to absorb solar energy, the source of his power. In the comics, Superman's black suit - called the Recovery Suit, or the Regeneration/Solar Suit - debuted following The Death of Superman in Reign of the Supermen. Shaken, Luthor took Lane's dog tags, which ironically bore the Superman symbol. "To hell and back," Lane gasped with his final breaths.
Lane threw himself at Luthor, shielding him with his own body and allowing him to escape unharmed. Men fell as they scrambled to escape, but they had nowhere to run. Setting his jaw, this black-suited Superman unleashed his heat vision on the trenches.

Everyone turned slowly to look up, only to see Superman hovering high above them with a scowl on his face. Luthor's platoon stopped shooting, and the return fire halted. "This is hellfire!" Lane cried into a walkie-talkie. The shot merely showed him and the others firing their guns off into the distance, with red lasers returning fire. The camera never peeled back to show who Luthor and his platoon were fighting.
The flashback picked up in a battlefield, where Luthor fought in the trenches alongside General Lane.

For one, Luthor isn't the maniacal supervillain as played by Jon Cryer in Supergirl. Chiefly, he relived some moments from his own world, which appeared to be like the Kents' world but for a few key differences. In "Heritage," the latest episode, Captain Lex Luthor revealed a little more about his vendetta against Superman. Superman & Lois just introduced another version of the Man of Steel - and one that wears a black suit, at that.
