What are the most interesting elements in Dark Angel crossover fanfiction?

In my opinion, Faith from Buffy and Alec from Dark Angel would be great to focus on. Faith has her own troubled past and her unique slayer abilities. Alec, on the other hand, is a transgenic with a bit of a roguish charm. The two of them could have a really interesting dynamic. Maybe they start off as rivals, not trusting each other, but as they face a common enemy, they start to understand and respect each other. And of course, Buffy and Max are also must - haves. They are the main characters of their respective shows and their leadership skills and different outlooks on life would make for a great story.

One idea could be that the vampires in Buffy's world somehow cross over to the Dark Angel universe and the transgenic characters have to deal with them. They might initially mistake vampires for some new kind of transgenic experiment gone wrong. Another idea is that Buffy herself travels to the Dark Angel world and teams up with Max to fight against a common enemy that is threatening both of their worlds, like a powerful demon that has found a way to use transgenic technology for evil purposes.

Abby and Logan could be a great pair. Abby is the brilliant NCIS forensic scientist, and Logan is a journalist in the Dark Angel world. They could work together to uncover the truth behind a conspiracy that involves both the military - related cases of NCIS and the transgenic secrets in Dark Angel. Abby could use her scientific knowledge to analyze evidence, and Logan could use his journalistic skills to dig up information and expose the truth to the public.

One idea could be that a case in NCIS leads them to discover a secret project related to the genetic experiments in Dark Angel. Maybe they find a link between a murdered Navy officer and a group trying to recreate the transgenic experiments. So, the NCIS team has to work with Max from Dark Angel, who has her own knowledge and skills in this area.

The blend of different universes is the most interesting. For example, if chowder crosses over with a show about superheroes, seeing chowder characters in a world full of superpowers is cool.

The most interesting elements? Well, first off, the world - building aspect. When komaeda is crossed over into a new world, like in a 'Naruto' crossover, we get to see how the two worlds' cultures and power structures blend or clash. His 'luck' power can have unforeseen consequences in a world full of ninjas. Then there's the element of how he challenges the status quo of the new world. In a 'Code Geass' crossover, his presence might disrupt the carefully planned power plays of the characters in that world. And finally, the way his character can be a catalyst for change in the new world, like in a 'Sword Art Online' crossover, where his actions could potentially change the outcome of the game - world events.

The clash of different art styles is one interesting element. For instance, when dororo crosses over with a more modern - looking anime like One Punch Man. The detailed, somewhat dark art of dororo against the more simplistic, comical art of One Punch Man creates a visual contrast that can be really engaging in fanfiction.

Character development is also a key aspect. When characters from different shows meet in a crossover fanfiction, they often have to grow and change in new ways. For instance, in a Blindspot and CSI crossover, the CSI forensic techniques might influence how the Blindspot characters approach evidence, leading to new perspectives and personal growth for them.

One challenge is integrating the different mythologies. 'Supernatural' has its own complex lore about demons, angels, and the like, while 'Dark Angel' has the whole genetic - engineering and post - apocalyptic backstory. Merging these two can be really tricky.

The character interactions are often the most interesting part. For example, when characters from different Marvel groups meet, like Iron Man and Captain America from the Avengers meeting Wolverine from the X - Men. Their different personalities can lead to some really fun dialogue and tense moments.
