Many anime universes are built around unique power systems, different laws of physics, and distinct hierarchies of strength. If Sung Jin-Woo, with his Shadow Monarch abilities, were to find himself in another anime world, the balance of power in that universe could change drastically.
His ability to summon an army of shadows, grow stronger with every battle, and regenerate from severe injuries would make him a force to reckon with. However, each anime universe has its own rules, and some might restrict his abilities or challenge him in ways he has never encountered before.
Would he still dominate the battlefield, or would certain characters be able to push him to his limits? The level of resistance he would face would depend on the nature of the world he enters, as some universes are known for their overpowered warriors, gods, and supernatural beings.

The question remains: how would Sung Jin-Woo fare in different anime settings?
Facing the Powerhouses of the Dragon Ball Universe
One of the toughest challenges Sung Jin-Woo could encounter would be stepping into the Dragon Ball universe. This world is home to fighters capable of destroying planets with a single attack, moving faster than the speed of light, and achieving power levels beyond human comprehension.
While Jin-Woo’s ability to grow stronger over time would be beneficial, it is uncertain if he could reach the heights of characters like Goku, Vegeta, or Beerus.
The Saiyans, in particular, have the advantage of limitless growth, similar to his own, but on an entirely different scale. The biggest challenge for Jin-Woo would be keeping up with the sheer speed and energy-based attacks of Dragon Ball fighters.
Unlike in his world, where battles are mostly grounded, Dragon Ball characters often fight in mid-air, teleport across vast distances, and unleash energy blasts powerful enough to wipe out entire landscapes.
If Jin-Woo were given enough time to adapt and train under someone like Whis, he might develop new techniques that would allow him to survive. However, without the ability to use ki, he would struggle against the strongest fighters in this universe.
On the other hand, his army of shadows could prove to be a unique advantage. Even if he is outmatched in raw strength, an endless supply of powerful warriors under his command could help him overwhelm opponents who rely on solo combat.
His ability to resurrect fallen warriors as shadows could also give him an edge, as he could potentially recruit some of the strongest fighters in the universe to his side.
The outcome of his battles in this world would largely depend on how well he could adapt to the energy-based combat system.
Battling Titans in the Attack on Titan Universe
If Sung Jin-Woo found himself in the Attack on Titan universe, he would be nearly unstoppable. This world is plagued by monstrous titans that terrorize humanity, but compared to the enemies Jin-Woo has faced, these creatures would pose little threat to him.
His agility, strength, and shadow soldiers would allow him to wipe out entire armies of titans without breaking a sweat. Unlike the Survey Corps, which relies on ODM gear to maneuver around titans, Jin-Woo could easily take them down with his raw speed and strength.
The real question in this universe would be how he interacts with the humans struggling to survive. Would he take command of the military and lead the fight against the titans, or would he operate from the shadows and eliminate them without revealing his true power?
If he were to use his abilities to raise fallen titans as shadow soldiers, he could create an unstoppable force that would end the war in a matter of days.
One challenge he might face is the mysterious nature of the titans themselves. While he is used to fighting monsters in dungeons, the origins of the titans involve complex scientific and historical factors.
If he were to attempt to turn a titan into a shadow, would it function the same way as his other summons, or would something go wrong due to the unusual biology of these creatures? This question alone could make his time in this universe an interesting experience.
How Jin-Woo’s Abilities Could Change Other Universes
Sung Jin-Woo’s presence in any anime universe would likely disrupt the natural balance of that world. In universes where strength is determined by rigorous training and inherited abilities, his unique power system could create an unpredictable advantage.

His ability to revive fallen enemies as loyal soldiers would also alter the course of many battles, especially in worlds where death is considered permanent.
However, some universes would challenge him in ways he has never encountered before. Worlds where power is drawn from sources beyond physical strength, such as Nen in Hunter x Hunter or cursed energy in Jujutsu Kaisen, might limit his abilities if he cannot adapt to their systems.
If he cannot learn to manipulate the energy unique to those worlds, he may struggle against the strongest fighters who have mastered those arts.
At the same time, his intelligence, battle experience, and adaptability make him more than just a brute-force fighter. Given enough time, he could find ways to integrate into any universe, learning its strengths and weaknesses to turn them in his favor.
Whether he dominates his opponents or faces true defeat would depend on how well he adjusts to the rules of each anime world.
