Takato from Tamers could be another good one. Since Takato created Guilmon, his approach to Digimon is different from Davis'. They could learn from each other and maybe combine their skills to face a common threat.
Tai from the original Digimon series could be a great crossover character. They both have leadership qualities and it would be interesting to see how they interact, whether they compete or cooperate.
Agumon from the original series could also be a good crossover character. Davis has his own Veemon, but seeing how he and Agumon interact, given Agumon's different personality and abilities, could create some really fun and interesting storylines. For example, they could have a friendly competition to see who can evolve faster in a dangerous situation.
One idea could be that Davis gets transported to a different Digimon universe where the rules are all mixed up. For example, Digimon don't evolve in the traditional way. He has to figure out how to adapt and find his way back home while also making new friends and facing new enemies.
One character who could betray Davis is Ken. Maybe Ken feels that Davis is too impulsive and is leading the group in the wrong direction. So, in an attempt to take over and lead in what he believes is a better way, he betrays Davis.
One interesting aspect in Digimon fanfiction about Davis and darkness is how his relationships with other characters change. His friends might be suspicious of him if he starts showing signs of being influenced by darkness. Or, he could find an unexpected ally who has also had experiences with the darker side of the Digimon world. This can create complex and engaging storylines.
One possible plot could be that Tony, from NCIS, is on a case that somehow intersects with Davis and Okoye's world. Maybe it involves some sort of international conspiracy. Tony's investigative skills could be put to the test as he teams up with Davis and Okoye, each bringing their own unique abilities to the table.
One possible plot could be them facing challenges as a married couple in the digital world. Maybe they have to deal with new Digimon threats together while also managing their relationship.
In some Digimon fanfiction, Davis could be depicted as being tempted by the darkness. His ambition or desire for power might lead him to consider the dark side, but in the end, he would have to make a choice between it and his friends and values. This makes for a very character - building storyline for him.
