It could be another vampire clan. They might see Cartman and Kyle's relationship as a threat to their own power or way of life. For example, if Cartman and Kyle are trying to promote co - existence between vampires and humans, the other clan might oppose it.
Perhaps Cartman, as a vampire, turns Kyle into a vampire against his will. Kyle then has to deal with his newfound vampiric nature while still trying to hold onto his moral compass. This could lead to a lot of internal conflict and interesting character development.

To write South Park Kyman fanfiction, it's important to be creative. You can think about different settings, like a high - school AU (alternate universe) for them. Also, pay attention to the dialogue. Since it's South Park, the dialogue should be snappy and in - character.

One possible fanfiction could involve a crossover between Rosario Vampire and Arrancar. The unique powers and characteristics of both vampires and arrancar could create interesting plotlines.

Well, there could be epic battles. The Rosario Vampire characters are used to a certain type of vampire - related challenges, but arrancar are a whole different level.

Maybe he'd have to learn new techniques or team up with unexpected allies.
