A third plot twist could be that the competition is revealed to be a ruse by one of Batman's enemies. They set up the whole 'competing for his affections' scenario to distract Batman and his allies while they carry out a major crime in Gotham. So, the characters competing find out they've been used and have to decide whether to still pursue Batman or help him stop the real threat.
Another plot twist might be that Batman himself realizes he has feelings for someone unexpected while the others are competing. Maybe he falls for a civilian who has no idea about his double life at first, which throws off all the competitors who thought they knew what Batman wanted.
A character can stand out by having a unique skill set. For instance, if a character is an expert in a rare form of martial arts that Batman is unfamiliar with, it would draw his attention. This shows that the character has something different to offer compared to the others vying for his affections.
Loyalty is crucial. In the fanfic, if your character is always there for Btaman, through good times and bad, it will make your character more appealing. For example, not abandoning him when he faces difficulties.

One common plot twist could be Batman being betrayed by a close ally like Robin. Maybe Robin gets brainwashed by a powerful villain and turns against Batman.

A really interesting plot twist would be if Ivy discovers that Batman has a secret identity that is related to plants in some way.

In some 'naruto batman fanfic', a plot twist could be that Naruto's chakra is somehow linked to the power source of Batman's technology. So when Naruto is in danger, it affects Batman's gadgets.

One common plot twist could be that a seemingly harmless monster turns out to be an ally in disguise. For example, a small, cute - looking monster that everyone underestimates actually has the power to defeat a much larger and more menacing one. Another plot twist might be that Artemis discovers a hidden connection between herself and one of the monsters, like they share a common origin or a long - lost relative. And sometimes, the monsters are not actually monsters but rather victims of a curse, and Artemis has to find a way to break the curse instead of simply fighting them.
One common plot twist could be that Issei betrays his friends for power. Maybe he's lured by a powerful devil who offers him unimaginable strength on the condition that he turns against his comrades.

One possible plot twist could be that Batman is actually Bruce Wayne's long - lost twin brother.

This would completely change the dynamic between Bruce and Batman.
