Wanda could be an interesting candidate. They both have a deep connection within the Avengers. Wanda's powers could be linked to Natasha's in some fanfic scenarios. For example, Wanda could use her powers to shield Natasha and her relationship from the prying eyes of the world, while Natasha uses her skills to protect Wanda from physical threats.
Maria Hill could also be a candidate. They have worked together closely in the past. In a fanfiction, their relationship could develop into something more romantic. Maria's no - nonsense attitude and her leadership skills could complement Natasha's skills. Their relationship could be a secret because of the professional environment they are in and the potential impact on the Avengers' dynamics.
Catwoman could be a great candidate. In the comics, she has a complex relationship with Batman. In fanfiction, they could get married and she could use her skills as a thief - turned - hero to help Batman in different ways. She already has a deep understanding of the criminal underworld which would be beneficial in their fight against crime.
One good candidate could be an original character. For example, a powerful kunoichi from a small, peaceful clan. She could bring a different perspective to Madara's life. Another could be a character from another ninja village, like a Kiri ninja who was sent as a diplomat and ended up falling for Madara.
Another plot could revolve around the secrecy itself. Natasha has kept her wife a secret not because she doesn't trust the Avengers, but because her wife was once an enemy agent who has now reformed. The story could be about how the Avengers gradually discover the truth and learn to accept Natasha's relationship and her wife's new identity.
Anko Mitarashi could be a good candidate. She's strong -willed and has her own set of skills. Her somewhat wild personality could contrast well with Kakashi's more reserved nature. They could have met during a mission and over time, developed feelings for each other.
One candidate secret story could be about a politician who once had a passion for painting but kept it a secret during his campaign. He was afraid that the public might think he was too artsy and not focused enough on more 'serious' matters like economy and security.
In such a fanfiction, their relationship could work based on mutual respect. Harry, being a powerful wizard, could offer Natasha a different perspective on problem - solving. Natasha, on the other hand, could teach Harry about her world's combat and survival skills. They could form a strong bond by relying on each other's strengths.
Personal insecurities can be included. For example, a candidate might be secretly insecure about their educational background, even if they are well - qualified on paper.
Draco Malfoy could be an interesting candidate. Their long - standing rivalry could transform into a deep understanding and love. They have a lot of history together, which could be explored in a romantic context.
One good candidate could be a powerful sage. Sages in the Naruto universe are known for their wisdom and great power. If he was Kaguya's husband, he could have taught her many things about chakra and the world before she turned bad. This would add an interesting backstory to Kaguya's character and also create new plotlines about the origin of chakra in the Naruto world.
