The Plot Twists:
- The Hammer of Boravia / Ultraman: The mysterious monster enforcer beating Superman is revealed to be Ultraman, a genetic clone of Superman created by Lex Luthor using stolen Kryptonian DNA.
- The Manipulated Kryptonian Recording: Lex leaks a broadcast claiming Jor-El and Lara sent Kal-El to conquer Earth. In reality, the damaged recording was incomplete; Lois Lane retrieves the full uncorrupted file, proving his parents sent him purely to live, love, and preserve their legacy through peace.
- The Pocket Universe Trap: Lex uses government authority via A.R.G.U.S. to imprison Superman inside an artificial pocket universe dimension housed beneath LuthorCorp.
Climax & Ending: With Superman trapped, Lex triggers a dimensional rift threatening to pull Metropolis into a black hole while deploying Ultraman and The Engineer. Mister Terrific and Metamorpho assist Superman in escaping the pocket universe. Clark delivers a televised speech explaining his human feelings and vulnerabilities to win back global trust. In the final battle, Ultraman is defeated and consumed by the black hole portal, and Superman stabilizes the tear. Lex's corporate crimes are exposed by Lois and the Daily Planet, leading to Lex's arrest and imprisonment in Belle Reve.
Mid/Post-Credits Revelations: Superman visits his cousin, Kara Zor-El (Supergirl), who is drinking on a red-sun planet, setting up her standalone film.
