James Gunn Weighs In: Green Lantern vs. Superman Showdown - Who Would Win?

In a recent discussion, James Gunn shared his thoughts on a hypothetical battle between Green Lantern and Superman. The characters were introduced in the Superman movie released in July 2025, sparking curiosity among fans about who would emerge victorious in a clash. Gunn expressed his belief that Green Lantern, specifically Guy Gardner, could defeat Superman in a fight. This revelation came during an episode of Peacemaker: The Official Podcast, where the topic of a potential showdown between Langston Fleury and Green Lantern was raised.
Despite some differing opinions among the cast, Gunn stood by his assertion that Green Lantern had the potential to overcome Superman in a battle. While Jennifer Holland, who portrays Emilia Harcourt in Peacemaker, leaned towards Superman as the victor, Gunn emphasized that the fight would be a challenging and intense encounter. The tension between Gardner and Superman was evident in the movie, particularly during a confrontation where Gardner provokes Superman by challenging him to attack.
Although the actual showdown between Green Lantern and Superman is not currently planned in the DC Universe, fans have engaged in debates about the outcome of such a battle. While Gardner is known for his formidable abilities, it is generally accepted that Superman would likely prevail in a fight between the two. This conclusion is supported by the fact that Gardner has not officially defeated Superman in the comics. The speculation and excitement surrounding the potential clash between these two iconic characters continue to captivate fans and fuel discussions about their respective strengths and abilities.
