How Would Solo Leveling Change If the Rulers and Monarchs Fought Side by Side?

A united front between Rulers and Monarchs could have reshaped the multiverse.

The ongoing war between the Rulers and the Monarchs shaped the balance of power across dimensions, with both sides locked in a conflict driven by ancient grudges. Their battle determined the fate of countless worlds, but what if they had put aside their differences and fought together?

A temporary alliance between these powerful beings would have created an unstoppable force, altering everything that was once known about their war.

The energy unleashed from such a collaboration would have dwarfed any previous battle, shaking the very foundation of existence itself. If they combined their strengths instead of fighting against each other, their combined power could have either protected the multiverse or destroyed it.

The question remains—would their unity have been a blessing or a catastrophe? Would their enemies have stood a chance, or would their sheer force have turned them into the greatest threat of all?

The Power That Would Have Been Unleashed

The Rulers and Monarchs were among the most powerful entities to ever exist, each possessing unimaginable strength and abilities that could alter reality. The Rulers, as protectors of order, wielded divine energy that granted them overwhelming offensive and defensive capabilities.

Their ability to control light and enhance those they deemed worthy made them ideal guardians of existence. On the other hand, the Monarchs thrived in chaos, drawing power from destruction and commanding armies of monstrous beings. Their dark energy, which could consume worlds, made them feared across all realms.

If these two forces had combined their abilities, the result would have been something never seen before. Light and darkness would no longer be opposing elements but instead complementary forces, fusing into a destructive or protective energy unlike anything else.

Their combined armies—comprised of Celestial Beings and shadow-infused creatures—would have been invincible, capable of erasing entire civilizations or defending them from any threat. No enemy, no matter how powerful, would have been able to challenge such a force.

The Impact on Humanity and Other Civilizations

A union between the Rulers and Monarchs would not have been without consequences for the weaker races, including humanity. If their alliance was formed with noble intentions, they could have acted as guardians of the universe, eliminating threats that even the strongest hunters could not withstand.

Humans might have benefitted from their protection, gaining more time to develop their own strength without fearing the dangers of external wars. Their presence could have reshaped the balance of power on Earth, possibly preventing the rise of dangerous dungeons or the appearance of calamity-class monsters.

However, if their alliance was driven by conquest instead of protection, then no civilization would have been safe. The combination of their abilities would have made them nearly unstoppable, leaving no force capable of resisting them.

Entire worlds could have been wiped out or enslaved, and humanity might have been nothing more than an afterthought in their pursuit of dominance. Even the strongest hunters and guilds would have had no choice but to bow before them or be erased.

Would Their War Have Ever Ended?

Despite the overwhelming strength that would have come from their unity, an important question remains—would such an alliance have lasted? The war between the Rulers and Monarchs was fueled by hatred and opposing ideologies.

The Rulers believed in order, while the Monarchs thrived on destruction. Their very existence contradicted each other, making any form of lasting peace almost impossible.

Even if they had fought together temporarily, it is likely that their differences would have resurfaced once the common enemy was eliminated. Their combined power could have led to the creation of a new form of warfare, one far worse than anything that had existed before.

Instead of the old struggle between light and darkness, a new conflict might have emerged—one between those who sought to use their power for stability and those who wished to unleash it for chaos. If that happened, the war that followed would have been far deadlier than the one before it.

The Consequences of Such a Union

If the Rulers and Monarchs had stood side by side, their influence over existence would have reached unimaginable levels. They could have rewritten the laws of the universe itself, determining who lived and who perished.

Their control over time, space, and reality would have turned them into gods in every sense of the word. No force, natural or supernatural, would have been able to defy them.

The possibility of such power falling into the wrong hands would have been a terrifying prospect. Even if their unity had begun with good intentions, the temptation to abuse their strength would have been ever-present.

Eventually, one side might have tried to take full control, leading to betrayals and conflicts even more devastating than their previous war.

The question would no longer be about who was strongest but rather who would be left standing when the dust settled. While their battle had caused destruction, their alliance could have led to something even more unpredictable.

Whether they would have become the greatest protectors or the ultimate threat is something that may never have a clear answer. What is certain is that if they had fought together, the world would never have been the same again.
