Well, there are several challenges. Firstly, there's the matter of their origin stories. Supergirl comes from a place of hope and family values, while Doomsday was created for destruction. This fundamental difference in their beginnings could cause a rift. Secondly, their allies and enemies would play a role. Supergirl's friends would likely be against the relationship, thinking Doomsday is a bad influence. And Doomsday's 'creators' or those who control him might try to use the relationship to their advantage, which would put a strain on their love.
One major challenge would be public perception. Supergirl is seen as a hero, and Doomsday is known as a destroyer. People would be very much against their relationship. Another challenge could be Doomsday's nature. He has a tendency towards destruction, and Supergirl is all about saving lives. It would be hard for her to be with someone whose instincts are so different from hers.
The first challenge is trust. Given Doomsday's history of causing chaos, Supergirl would have a hard time fully trusting him. And Doomsday, who may not be used to positive emotions like love, might struggle to trust Supergirl's intentions. Also, their powers are so different in nature. Supergirl's powers are more about protecting and helping, while Doomsday's are destructive. This contrast in power usage could create a lot of friction in their relationship.
One major challenge would be their different natures. Darkside is often associated with darkness and evil, while Supergirl stands for truth, justice, and the American way. Their moral compasses seem to be pointing in opposite directions. People around them, like Supergirl's friends and allies in the Justice League, would likely be very against their relationship, which could put a strain on it.
One way their relationship could work is through mutual understanding of their powers. Doomsday is a powerful being, and Supergirl, with her own set of abilities, could find a connection in that. They might start by realizing that they are both somewhat outcasts in different ways. Doomsday is a creation that is feared, and Supergirl is an alien on Earth. Their relationship could be based on this shared sense of otherness and a desire to protect each other from a world that may not fully accept them.
One major challenge would be the age difference. Tsunade is much older than Naruto, and this could lead to social and cultural disapproval in the Hidden Leaf Village. Another challenge would be their different positions in the village. Tsunade is the Hokage, and Naruto is a young ninja. There could be power dynamics at play that make a relationship difficult. Also, Tsunade has a lot of emotional baggage from her past, like the loss of her loved ones, which might make it hard for her to fully open up to Naruto and embrace a new relationship.
Society would be a big problem. Hidan is a criminal in the eyes of most. The reader would have to deal with the stigma of being associated with him. People might shun the reader or even try to harm them. And Hidan's violent nature and his penchant for killing could be a huge obstacle for a healthy relationship.
She might face the challenge of intangibility. Ghosts can be intangible, making it hard for Supergirl to land a physical blow.
Another challenge is the difference in their lifestyles. Lloyd is used to a life full of action, danger, and the need for secrecy as a ninja. The reader, on the other hand, may lead a more normal life. Adjusting to each other's worlds can be difficult. For example, the reader may not be able to always keep up with Lloyd's fast - paced ninja life, and Lloyd may find it hard to adapt to the simplicity and routine of the reader's life at times.
Hermione is a Muggle - born, and Snape has his own complex history with Muggle - borns. They would need to work through Snape's potential prejudices and Hermione's insecurities about that. And of course, Snape's brooding and often cold personality might clash with Hermione's more outspoken and passionate nature.
One major challenge would be the difference in their lifespans. Haldir, as an elf, has a much longer lifespan compared to the human. This could lead to the human growing old while Haldir remains relatively unchanged, which would be a source of great sadness. Another challenge could be the cultural differences. Elves have their own traditions, values, and ways of life that might be very different from human ones. For example, elves might have a more reserved and formal approach to relationships, while humans could be more spontaneous.
In a fanfiction where Po and Tigress fall in love, they'd face the challenge of communication. Tigress is not very expressive with her emotions, and Po might misinterpret her silence at times. Also, their different backgrounds could be an issue. Po grew up in a noodle shop, while Tigress was trained in a more formal and strict kung - fu environment. This difference in upbringing could lead to clashes in their values and ways of thinking. Additionally, they may face competition within their relationship. Both are skilled fighters, and there could be times when their competitive streaks get in the way of their love, especially when it comes to matters related to kung - fu and proving themselves.
In some fanfiction concepts, they could face the challenge of different responsibilities. Poseidon had to manage the entire sea realm, deal with storms, and protect sailors. Amphitrite, on the other hand, might have been more focused on the well - being of the sea creatures. Their busy schedules could have made it difficult for them to spend quality time together. Additionally, there could be family - related issues. Poseidon's family, like Zeus, might have had certain expectations or demands that put strain on their relationship.
