A great 'Karna Crossover Fanfiction' is 'Karna and the Justice League'. In this fanfiction, Karna's backstory and his heroic qualities are explored in the context of the DC universe. He could potentially team up with Superman or Batman, and his abilities, such as his unrivaled archery skills and his near - invincibility in some versions, could be a great addition to the Justice League's roster.

There are some fanfictions that depict Arjuna and Karna in alternate universes. For example, in some stories, they might be friends instead of rivals. They could be in a modern - day setting where they have to put aside their age - old grudges and work together towards a common goal. These types of fanfictions offer a fresh perspective on their relationship and can be really interesting to read.
One common theme is power comparison. Since Karna is a very powerful character, in crossovers, his powers are often compared to those of the characters in the other universe. For example, in a crossover with the Marvel universe, his archery skills might be compared to Hawkeye's.
One idea could be to cross Karna with a modern - day superhero universe. Imagine Karna's powers and his noble character in a world full of caped crusaders. He could be a sort of lone wolf hero, respected for his strength but also feared for his unwavering sense of justice.
Finally, have a satisfying resolution. Whether it's Karna achieving a great victory or making a self - sacrificing move for the greater good of the crossover world, the ending should tie up loose ends. Don't forget to include some twists and turns along the way to keep the reader engaged. Maybe Karna discovers a hidden power within himself that is only unlocked in the crossover world.
