Who are some characters that could play important roles in batman arrow crossover fanfiction?

Neville could play an interesting role. Maybe he could be the one who discovers a new magical plant that is needed for a potion to cure an illness that Ginny or Harry contracts during their marriage. Luna could also be involved. She might come to them with some strange but useful prophecies that help them in a difficult situation, like dealing with a dark wizard who has a grudge against Harry even after the war is over.

Sasuke could also be important. He might be initially skeptical of Naruto's Sage Chakra but later see its potential and even collaborate with Naruto. Also, the Great Toad Sage is a key character. It could give Naruto new prophecies related to his Sage Chakra, leading him to new adventures and challenges. Tsunade could also play a role, perhaps in helping Naruto understand the medical aspects of Sage Chakra and how it affects his body.

Hermione would definitely be important. She could use her extensive knowledge to help Harry understand his creature inheritance. For example, she might research ancient texts to find out more about the origin of his inherited traits.

Alfred Pennyworth could be included. He could offer his wisdom and support to both heroes. Maybe he even has some insights about the similarities and differences between Gotham and Starling City. Another character could be Felicity Smoak. She could help with the tech - related aspects of the case they are working on together.

Sakura could play an important role. She might be more concerned about Naruto's well - being after such a tough fight. She could also use her medical skills to help in the rebuilding of Konoha. Kakashi, too, could be significant. He could guide Naruto in understanding his new powers better and also contribute to the village's security plans.

Sakura could have a different relationship with Naruto in this fanfiction. Since Tsunade trained her, there could be more of a family - like bond between Sakura and Naruto. Also, characters like Sasuke would still be relevant. His rivalry with Naruto could be affected by Naruto's new family situation. Additionally, Shizune, Tsunade's assistant, could be involved, perhaps acting as an older sister figure to Naruto.

His friends are very important. Rukia, for sure. She has a lot of knowledge about the spiritual world and could be the one to figure out what's wrong with Ichigo. Orihime with her healing powers also plays a big role. She might use her abilities to ease his pain or at least keep his condition from getting worse. Uryu could also be important as he might use his Quincy skills to analyze what's causing Ichigo's sickness.

Well, Naruto is the key figure in these fanfictions. But characters like Tsunade can't be ignored. As the Hokage, she may give Naruto special tasks or resources that aid in his rise. Rock Lee is also common. His dedication to training and his unique fighting style can inspire Naruto. And Neji, before his death in the original series, could be a character who, in fanfiction, has a change of heart and helps Naruto understand more about the Hyuga clan's secrets, which in turn helps Naruto gain more power and influence.

Obviously, Dawn and the members of Team Rocket like Jessie, James, and Meowth are the main ones. But there could also be Dawn's Pokémon, like Piplup, which might try to rescue her. And there could be other Pokémon trainers or characters from the Pokémon world who might get involved in the rescue mission.

Hermione would definitely be an important character. She could use her vast knowledge to help Harry throughout the pregnancy, whether it's with medical advice or just emotional support. Another one could be Dumbledore. He might offer his wisdom and protection, guiding Harry through this unusual situation. And of course, the Weasley family, especially Molly. She could be like a mother figure to Harry during this time, making sure he's eating well and taking care of himself.
