She might be a foreign diplomat or someone important from another land. Riezem could be trying to use her as a bargaining chip or to start a war, and Naruto, being the protector of peace, steps in to save her. This would also add an interesting political aspect to the fanfiction as Naruto would have to deal with the diplomatic implications of his actions.
It's also possible that the woman is a ninja from a hidden village that has a connection to Naruto. Maybe she was on a secret mission and got caught by Riezem. Naruto would then be motivated not only by his sense of justice but also by his loyalty to his ninja comrades to save her.
Well, one possibility could be that Naruto uses his speed and ninja skills to rescue the woman. Maybe she was being held captive by Riezem's henchmen. Naruto could sense her distress with his sharp ninja senses and quickly dash in, taking out the bad guys with his Rasengan. Then he'd safely escort the woman to a secure place.
Well, in many fanfictions, Naruto might use his signature jutsus like the Rasengan. He could sense the danger the woman is in using his enhanced ninja senses and then quickly dash in to counter Rizevim's attack with his powerful moves, overpowering Rizevim and rescuing the woman.
Batman could be a likely candidate to save Wonder Woman. He has a long history of dealing with the Joker and his antics. His detective skills would help him track down where the Joker is keeping Wonder Woman.
Anko Mitarashi could be a great snake - like character. She has the snake summoning ability and a bit of a wild personality. In the fanfiction, she could have some deeper connection to a snake - based power or a snake - like race.
It could be an original character created specifically for this fanfiction. Maybe she's a damsel in distress with a special power or a connection to Naruto's past that we don't know yet.
It could be Sai. He has a rather stoic nature and his skills as an Anbu would be useful in this situation. He could use his ink techniques to hold Anko back while rescuing Naruto.
A character with a completely different personality but a similar goal. They could be more light - hearted while she is serious, but they both want to achieve the same thing. Their interactions would be interesting as they balance each other out.
Well, it depends on the situation. If the fight takes place in the Naruto universe where Naruto can draw on natural chakra more easily and has the home - field advantage, he could be very strong. He also has his Nine - Tails chakra which is extremely powerful. On the other hand, Wonder Woman has years of combat training and her divine weapons. In a battle of wits and strategy, Naruto's experience in fighting various opponents in his world might give him an advantage, but Wonder Woman's overall power set is also very formidable.
Well, Naruto could save a woman who is trapped in a collapsing building during an enemy attack. He could use his super strength and speed to get her out safely. Then, the woman might be so grateful that she offers to help Naruto in his future missions in some way, like providing him with valuable information about the enemies.
Sakura would be a likely candidate. As a skilled medical ninja, she has the knowledge and ability to diagnose the poison and attempt to create an antidote.
