One of the common themes is adaptation. A kryptonian in a new fictional world, say like the Star Trek universe, has to adapt to new technologies, cultures, and rules. They can't just rely on their Kryptonian powers all the time. Also, friendship and alliances are often themes. In a crossover with the Harry Potter world, a kryptonian might form alliances with the Hogwarts students to fight a common enemy. And of course, discovery is a theme too. Discovering new things about the crossed - over world and also about themselves as a kryptonian in a different context.
A really popular kryptonian crossover fanfiction is 'The Kryptonian in Middle - earth'. It's a fascinating read as it imagines a kryptonian in the world of Tolkien. The kryptonian has to deal with the different races and the magic in Middle - earth, which is very different from what they are used to on Krypton. There's also 'Kryptonian vs. the Transformers', which is a fun and action - packed fanfic that pits the super - powered kryptonian against the giant robots.
First, do your research on Kryptonian lore. Know their powers, culture, and history. Then, create an original character with unique traits within that framework. For example, your OC could have a different take on their Kryptonian powers. Next, think about how this character will interact with the Supergirl universe. Maybe they become an ally or a rival.
A big theme is also about acceptance. In many fanfictions, the hybrid has to face discrimination from both Saiyans and Kryptonians at first. For example, the Saiyans might see them as too soft because of the Kryptonian influence, while the Kryptonians might be wary of their Saiyan aggression. Overcoming this lack of acceptance and finding a place where they are respected is a common plot point. Also, the exploration of new powers that come from the combination of the two races is often seen. Their abilities can be unique and different from what either race has on its own, which makes for interesting storylines.
There's also 'The Hidden Kryptonian'. This one focuses on a female OC who discovers her Kryptonian heritage later in life. The author does a great job of showing her struggle to come to terms with it and how it changes her relationships. It's a story that keeps you hooked from start to finish.
Next, think about her powers. You can give her the standard Kryptonian powers like super strength and flight, but also add some unique twists. Maybe she has a special power related to Kryptonian technology. Also, consider her personality. Is she shy or bold? This will shape how she uses her powers.
Well, it could be a valid concept in the realm of fan creativity. Fanfiction often takes elements from different sources and blends them. However, Harry Potter is centered around magic with wands, spells, and Hogwarts, while Kryptonians have superpowers from their alien physiology. It might be hard to make it work cohesively, but it could lead to some unique and out - of - the - box stories.
To write such fanfiction, you could start by creating a crossover point. Maybe a portal opens between the Kryptonian world and the wizarding world. Then, characters from both sides start to interact. A Kryptonian could be amazed by magic and try to learn it, while wizards could be in awe of the Kryptonian's raw power. You'd have to balance the two different power systems and cultures so that the story makes sense.
A smart Kryptonian in a Naruto fanfiction might start a school of their own. They could teach both Kryptonian knowledge and ninja skills. This would attract students from all over the Naruto world who are eager to learn something new. They could also use their intelligence to research and discover new forms of chakra or hidden ninja powers.
A Harry Potter and Kryptonian fanfiction might involve a crossover of the two worlds' technologies and magic. The Kryptonian science could interact with Hogwarts' magic in strange ways. For instance, the Kryptonian crystals could be used in potions or spells. And Harry, with his new - found Kryptonian heritage, might have to hide his powers from some in the wizarding world who would be afraid of them.
