Superman Movie Reveals How Lex Luthor Enters Fortress of Solitude
Curious how Lex Luthor managed to enter the Fortress of Solitude in Superman (2025)? As the iconic stronghold returns in James Gunn's reboot, the film reveals a calculated infiltration that ties directly to Superman's past battles, Kryptonian tech, and a shocking public betrayal. With clones, stolen messages, and weaponized perception at play, Luthor's plan goes deeper than expected.
Here's how Lex Luthor gained access and entered the Fortress of Solitude. Learn what it reveals about the fortress's biggest vulnerability.
Lex Luthor entered the Fortress of Solitude by using Ultraman, a clone of Superman created from his hair. The clone's exact genetic makeup allowed the Kryptonian systems within the fortress to recognize Ultraman as Superman, granting access without resistance. Luthor exploited this security loophole to breach the stronghold and execute his plan.
Luthor arrived with Ultraman and the Engineer, using the opportunity to steal a message recorded by Jor-El and Lara Lor-Van. The message revealed a directive urging Kal-El to conquer Earth and eliminate opposition—information that had been damaged in Superman's original copy. Luthor publicly broadcast the unedited version to damage Superman's reputation, portraying him as a potential threat to humanity.
The film does not show any significant defensive systems within the Fortress of Solitude. Unlike comic interpretations that feature a massive key or robotic guardians like Kelex, this version relies solely on Kryptonian biometric recognition. By acquiring Superman's DNA remnants from prior battles, Luthor was able to bypass any authentication protocols using his clone.
Once inside, Luthor secured the message and abducted Krypto. This breach enabled him to launch a coordinated plan. He broadcast the full Kryptonian message, shifted public sentiment, and framed Superman as a threat. The infiltration gave Luthor the means to sway global opinion and gain influence over government decisions involving Superman.
The fortress's vulnerability lies in its sole reliance on Kryptonian DNA for access. It lacks secondary verification systems or sentient security. This allowed Luthor to enter without triggering any alerts. Cloning Superman to reach the fortress exposed a major flaw in his defenses and revealed the extent of Luthor's calculated strategy.
