10 DC Alien Worlds That Would Defeat Earth

Earth is home to some of the strongest heroes and villains in the DC Universe. From Superman to Wonder Woman, DC’s brightest and mightiest often save Earth from invading forces. Earth has turned Brainiac and Zod away while repelling full-scale invasions from the Sinestro Corps and Black Lanterns, but Earth could still fall victim to coordinated attacks from other strong alien worlds.

Across the DC Universe, gods from the multiverse and world-eaters exist, ready to use their full resources to conquer Earth. From Darkseid and the hordes of monsters on Apokolips to Highfather and the powerful New Gods of New Genesis, some alien worlds could defeat Earth and the Justice Leaguers living there.

10 Oa Is The Green Lantern Corps’ Home Base

• Oa is home to the Guardians of the Universe
• Oa houses the Green Lanterns’ Central Power Battery
• Oa is located at the center of the universe

Where would Hal Jordan’s allegiances lie? The “greatest Green Lantern of all time” has fought for both the Green Lantern Corps and Earth’s Justice League, but who’s to say he wouldn’t turn on Earth to defend his fellow Lanterns? Oa is the center of the known universe, governed by near-immortal beings who harness the universe’s will.

Earth may have the Justice League, but Oa has the Guardians and Green Lanterns. Each Lantern’s power is potentially unlimited, based solely on their will and connection to their power ring. An army of Parallaxs, for example, would overwhelm Earth’s heroes.

9 Xanshi Returned In Blackest Night

• Fatality fought John Stewart as a Star Sapphire
• John Stewart caused Xanshi’s destruction
• Xanshi housed the Black Lantern Corps

Years ago, John Stewart failed to save the distant planet Xanshi, and his failure still haunts his nightmares. Black Hand capitalized on that trauma in Green Lantern‘s Blackest Night event when he resurrected Xanshi and all its inhabitants and recruited them into the Black Lantern Corps. John literally faced his fears when the undead Xanshi attacked.

On their own, Xanshi would be no match for the might of Earth’s heroes, but enhanced with Black Lantern rings, the undead planet of Xanshi would become an immortal threat with new members joining their ranks with each kill.

8 Rann & Thanagar Are Locked In War

• DC explored the Rann-Thanagar War in Infinite Crisis
• Adam Strange fights for Rann
• Hawkgirl and Hawkman are Thanagarians

Most DC Comics readers have probably heard of the planets Rann and Thanagar. Rann recently appeared in Tom King’s Strange Adventures miniseries, a fitting backdrop to a story that revolutionized Adam Syrange for modern fans. Thanagar is home to Hawkman and Hawkgirl and appeared frequently in the Justice League animated series.

Both planets are significantly more scientifically advanced than Earth. And Thanagar houses the finest soldiers in the universe. Rann and Thanagar have fought many wars against each other, but they could dominate Earth if they worked together for once.

7 Warworld & Mongul Take Only The Strongest Fighters

• Mongul and his family lead Warworld
• Warworld houses the grittiest, strongest fighters in the universe
• Warworld can destroy entire planets

Warworld is less of a planet and more of a galactic weapon. Warworld is mobile and destructive, possessing an intricate defense system accentuated by an equally powerful offense. If the Justice League were to somehow breach its defenses, they’d find an army of the galaxy’s most powerful fighters on the surface.

Those soldiers would be led by Mongul, the Warworld tyrant who is just as strong as Superman. The Man of Steel once had to battle his way out of Warworld in the beloved Justice League cartoon, and Warworld played a major role in the recent “Warworld Saga” that unfolded in Action Comics.

6 Krypton Is A World Of Supermen & Superwomen

• Krypton is centuries more scientifically advanced
• Kryptonians can become as strong as Superman under a yellow sun
• Krypton has spaceships and resources like Brainiac

Superman fights for truth and justice, defending Earth from all manner of threats. Fortunately, Superman was raised by good, hardworking people like Jonathan and Martha Kent. DC Comics readers have seen what an invasion of not-so-morally-just Kryptonians looks like.

Even without their superior genes, Kryptonians come from a technologically advanced world. Possessing all the same powers as Superman, Kryptonians could easily destroy Earth and have nearly done so in Action Comics and Frank Miller’s Dark Knight III: Master Race.

5 Starfire Comes From Tamaran

• Starfire and her sister, Blackfire, grew up on Tamaran
• Psions destroyed Tamaran
• Tamaranians have fought in many galactic wars against the Citadel

Earth houses some powerful heroes who don’t need armies at their backs. Superman and Wonder Woman could likely defend the planet by themselves, with no assistance from the rest of the Justice League. Earthlings, however, do not possess superpowers––most do not, anyway. Tamaran is a different story.

The beings on Tamaran are all powerful, each possessing the same abilities as Starfire, Blackfire, and the rest of their family. If Starfire led a war against Earth, surely betraying her fellow Teen Titans, the sheer combined might of the Tamaranian race would likely overpower Earth.

4 Mogo Is A Living Green Lantern Planet

• Mogo is a sentient planet who joined the Green Lantern Corps
• Mogo housed the GL Corps after Oa’s destruction
• Mogo helps the Green Lantern rings determine who is “worthy”

Oa may be the hub of the Green Lantern Corps, the center of the universe governed by the Guardians, but Mogo is a sentient, living planet chosen to be a Green Lantern itself. Mogo also acted as the Corps’ moral compass for years, directing power rings to recruits based on their “ability to overcome great fear.”

Mogo was instrumental in defending Earth from Sinestro’s assault during the Sinestro Corps War. Still, if it rotated its axis and pointed its giant gun at Earth, Mogo could cause serious damage with one precise, concentrated blast.

3 Qward Exists In The Antimatter Universe

• Qward is the ant-matter universe version of Oa
• The Anti-Monitor hails from Qward
• Qward houses the Sinestro Corps

Qward exists beyond the walls of the prime DC universe, housing fantastic machinery that is completely alien to Earthlings. The Anti-Matter, the being who has nearly destroyed the entire multiverse several times, notably in Crisis on Infinite Earths, originated in this antimatter universe.

Sinestro also crafted his legion of Sinestro Corps power rings on Qward. If he returned with schematics for new weapons, Qward’s engineers could likely craft deadly new machines to assist Sinestro or the Anti-Monitor in their next assault on Earth.

2 New Genesis Houses Highfather’s New Gods

• The New Gods possess powers that rival the Justice League
• The New Gods have access to Mother Boxes
• Highfather is one of the most powerful DC gods

New Genesis has warred with their neighboring planet, Apokolips, for years. Highfather and Darkseid, the two most powerful New Gods, have been locked in an eternal struggle, temporarily cooled during their peace treaty when they exchanged their sons. New Genesis is a longtime ally to Earth, but they’d have more than enough firepower to destroy it.

New Genesis is armed with Mother Boxes, technology far superior to Earth’s, allowing galactic teleportation and communication. The planet also houses an army of New Gods, like Lightray, Mister Miracle, and Orion; New Genesis outclasses Earth in every combative category.

1 Apokolips Houses Darkseid

• Darkseid has the resources to attack multiple planets across the multiverse
• Darkseid’s war generals have defeated Superman and the Justice League
• Darkseid often possesses the Anti-Life Equation

Darkseid is one of the Justice League’s most powerful villains. Alone, Darkseid could defeat the majority of the Justice League. With the power of the Anti-Life Equation at his fingertips, Darkseid nearly defeated the entire universe in Grant Morrison’s Final Crisis.

With the entire military might of Apokolips, evil gods, and hordes of parademons at his command, Darkseid could very well destroy Earth. He’s attacked the planet many times, invading it in the New Gods comic, the New 52 Justice League comic, and the Justice League Unlimited animated series.
