After DC Comics revamped its storylines following the Crisis on Infinite Earths, Superman’s past was largely erased. While some classic villains like Lex Luthor and Brainiac were reimagined, fans generally accepted these changes, and elements of the original history were later brought back. The story Superman: Exile, a 13-part series published across three comic books, saw Superman leave Earth and wander the universe alone, punishing himself for killing General Zod and his followers. This storyline also reintroduced Mongul, a unique yellow alien first appearing in 1980, as a major and dangerous enemy. The DC Universe has plenty of background to support an adaptation of Superman: Exile, but its grand scale would be best realized through animation.
