Batman's ability to strategize is top - notch. When Danny Phantom is hurt, Batman can come up with a plan to keep him safe and also find a way to get him back to full strength. Danny's ghost powers are a great asset. His flight can be used for quick transportation in situations where Batman's vehicles might be too conspicuous. If they are facing an enemy that has some sort of anti - technology measures, Danny's powers can still be effective. His invisibility can be used for stealth operations, and he can phase through an enemy's defenses. Batman can then analyze the enemy's weaknesses and come up with a counter - attack plan using Danny's powers to their advantage.
Well, Batman has his Bat - computer and all his high - tech gadgets which can be used to analyze data and find information. Danny Phantom, when hurt, can be healed faster in the Ghost Zone which Batman can't access directly. But Batman can use his resources to create a safe portal for Danny to enter the Ghost Zone to heal. In combat, Danny's powers of ectoplasmic blasts can be combined with Batman's combat training. Batman can direct Danny on when and where to use his powers for maximum effect. Danny's ability to turn intangible can also be used to disorient enemies, and Batman can take advantage of that moment of confusion to strike. Also, Danny can use his ghostly wail in a desperate situation, and Batman can use his knowledge of acoustics to make sure it has the most impact.
The ability of Danny to fly gives him an advantage in terms of mobility and scouting. He can quickly survey an area and report back to RC9GN. RC9GN's knowledge of his own world's layout and his ability to blend in with the environment can help Danny when they are trying to gather information on the ground. Their combined abilities make them a formidable team when it comes to facing threats in a crossover situation.
One plot idea could be that Danny Phantom is in Gotham City for some reason, maybe chasing a powerful ghost that has escaped into Batman's territory. He gets hurt during a fight with some of Gotham's villains who mistake him for a threat. Batman, being the detective he is, quickly figures out that Danny is not an ordinary 'meta' but a half - ghost. He helps Danny by providing him with a safe place to recover and using his resources to track down the ghost. Another idea is that Danny is hurt by a government agency that is trying to study his unique physiology. Batman steps in, using his influence to stop the agency from further harming Danny and helps him find a way to get back home to Amity Park.
Danny Phantom can go intangible and invisible, which would be really useful for sneaking up on enemies. Wonder Woman has her super strength and speed.

For example, if they were facing a group of powerful demons, Danny could scout ahead invisibly and then signal Wonder Woman to attack.
Naruto's ability to create shadow clones could be very useful in a fight alongside Lisbeth. He could send clones to distract enemies while Lisbeth focuses on using her blacksmithing skills to create or enhance weapons in the heat of battle. For example, she could quickly repair a damaged weapon using her knowledge and Naruto's clones could buy her the time she needs.
Well, Naruto's ability to quickly adapt and learn new jutsu combined with his vast chakra reserves is a great advantage. Karin's chakra sensing skills are very precise, which can help Naruto in battles by providing him with information about his opponents' chakra levels and any potential weaknesses. In addition, her healing powers can keep Naruto in top shape during long - drawn - out battles or difficult missions. For instance, if Naruto were to engage in a battle with a powerful enemy who has the ability to drain chakra, Karin could sense when Naruto's chakra is getting dangerously low and use her healing powers to boost his chakra levels or at least keep him stable until he can find a way to defeat the enemy.
Princess Cadence's ability to bring harmony and love, which is essential in her role as a princess, could have an impact on Naruto.

For instance, if there were some sort of dark creatures attacking her kingdom, Naruto could lead the fight while Princess Cadence used her powers to keep the morale of the people high.
Blue Beetle is often portrayed as a hero who is still finding his way and is full of enthusiasm. Batman, on the other hand, is a hardened veteran. Their personalities might clash when it comes to their approach to crime - fighting. Blue Beetle may want to rush in and save the day immediately, while Batman prefers careful planning. But this difference can also be a strength. Blue Beetle's eagerness can inspire Batman to be more action - oriented at times, and Batman's experience can teach Blue Beetle the value of patience and strategy.
Fem Percy is usually a very passionate character, driven by her sense of justice and loyalty to her friends and the world she comes from.

But they can complement each other well. For example, Fem Percy can bring some warmth and a different kind of moral compass to Batman's rather dark and often self - imposed lonely fight. Batman can teach Fem Percy about the importance of preparation and using intelligence in combat, which can be very useful for her in future battles and quests.
Naruto's ability to create multiple clones could be very useful in combination with Gildarts' brute strength. The clones could distract enemies while Gildarts moves in for a powerful strike.
