World Engines were built millenia ago when Krypton sought to expand across space, they were tethered to the thousands of scout ships they sent as part of a massive terraforming project.
After Krypton was destroyed, General Dru-Zod and his small band of survivors traveled for decades through space seeking ancient kryptonian settlements only to discover they all withered, they obtained a world engine and attached it to the black zero before heading to Earth.
Later, after being defeated in battle by Kal-El, an angered Zod ordered for the World Engine to be released to begin terraforming Earth into a new Krypton. Kal-El flew to the Indian Ocean and began attacking the World Engine as it started the terraforming process. The World Engine's defenses began attacking Kal-El who, fortunately, managed to destroy the World Engine before heading off to Metropolis to destroy the Black Zero and stop Zod once and for all.
- The World Engine is capable of landing speeds up to mach 24.
