Jonathan's Hamon and physical strength are impressive, but Meruem's power is simply on another level. He faces an almost impossible challenge against the Chimera King.
Josuke's Crazy Diamond is powerful and versatile, capable of creative battlefield manipulation and healing others. While strong, it likely isn't enough to defeat Meruem.
Jolyne's Stone Free offers incredible flexibility, transforming her body into string for unique traps and defense. Despite her adaptability, the power gap against Meruem remains significant.
Joseph can't match Meruem in strength, relying instead on his cunning and trickery to survive. His intellect, not brute force, is his best chance against the King.
Jotaro's Star Platinum, with its time-stop ability, offers a crucial advantage for survival. Five seconds of stopped time could provide a vital escape or opening against Meruem.
Rohan's Heaven's Door is a potent, albeit risky, weapon. If he can activate it to write commands into Meruem's mind before being attacked, victory is possible.
Johnny's Tusk ACT4, powered by the Golden Spin's Infinite Rotation, presents a unique threat. Its ability to bypass conventional durability could be Meruem's undoing.
Giorno's Gold Experience Requiem is the ultimate counter, capable of nullifying Meruem's actions and will. This Stand ensures Meruem's attacks never reach their intended target.
