Well, it could start with a moment of curiosity. Supergirl, being the inquisitive hero she is, might decide to explore Darkside's realm out of a sense of duty or just plain curiosity. There, she encounters Darkside in a different light than she expected. He might show her a side of his world that she never knew existed, and she starts to question her previous assumptions about him. This new - found understanding could be the spark that starts their relationship. As they continue to interact, sharing their thoughts and feelings about their respective places in the universe, their bond deepens and love blossoms.
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.
Well, it could start with Darkseid being intrigued by Supergirl's strength and purity. He might initially try to use her for his own evil purposes but gradually find himself falling for her. Supergirl, on the other hand, could see the possibility of redeeming Darkseid through love. Their relationship could develop as they face various challenges together, like threats from other villains or the moral dilemmas that come with their union.
Their relationship would likely become more intense. Beast Boy would probably be very supportive of Supergirl. He'd be constantly by her side, making sure she's okay. They'd start to think more about their future together as a family, not just as superheroes.
Their relationship could start off rocky. Naruto is used to his own world's way of doing things, and Supergirl has her own set of values from the Young Justice universe. But as they face challenges together, they start to respect each other. Maybe Naruto saves Supergirl from a tricky situation using his ninja stealth, and she in turn helps him understand the technology in the Young Justice world. This mutual assistance could lead to a deeper friendship.
Their relationship might start with mutual admiration. Diana sees Kara's strength and kind heart, while Kara is in awe of Diana's power and wisdom. As time goes on, they face challenges together, which deepens their bond. For example, they might team up to stop an intergalactic threat, and through that experience, they start to rely on each other more.
After the kiss, their relationship might develop gradually. They could start with small, secret dates. For example, flying to a remote place together where no one can find them. They'd share their deepest secrets and fears during these times.
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.
The relationship might develop in a very complex way. Given Lex Luthor's daughter's background, she could be both intrigued and afraid of Supergirl. They could be forced into situations where they have to communicate, like when they are both captured by a new villain. During their captivity, they learn about each other's hopes and fears. Supergirl might talk about her desire to protect the city and its people, while the daughter might open up about her struggle to break free from her father's shadow. This mutual understanding could gradually transform their relationship from one of enmity or suspicion to one of trust and even friendship.
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.
Supergirl might develop by learning to rely more on Alex's human - based skills and wisdom. For example, in a situation where her powers are nullified, she has to depend on Alex's combat training. Alex, on the other hand, could develop by becoming more confident in her role as Supergirl's support system.
