Geordi La Forge is a great choice. They already have a strong friendship in the show. In fanfiction, they could go on a special mission together where Geordi's engineering skills and Data's knowledge combine to solve a complex problem.
Worf. It would be interesting to see Data and Worf in a fanfiction adventure. Worf's Klingon warrior nature and Data's logic could lead to some great interactions. For example, they could be on a planet where they have to fight off some dangerous creatures. Worf would be all about the physical combat, while Data would be strategizing the best way to survive.
One interesting story could be about Data exploring emotions in a new and unique way. Maybe he encounters a new alien species that has a different understanding of emotions and it causes him to re - evaluate his own pursuit of them.
I really like 'TNG and Stargate SG - 1: The Unexpected Encounter'. In this fanfiction, the crew of the Enterprise - D from Star Trek TNG stumbles upon the Stargate. It's a fascinating read as it explores how the two different technologies and cultures would interact. There are some really cool moments where Picard has to negotiate with the Goa'uld, and Data tries to understand the Ancient technology.
Some of the best Star Trek TNG novels include 'Imzadi' by Peter David. It's a classic that delves deep into the relationship between Picard and Crusher. Another great one is 'Q - Squared' which features the mischievous Q in a complex and engaging story. 'Dark Mirror' also stands out, showing an alternate and darker version of the TNG universe.
I think 'Reunion' is a great Star Trek TNG novel. It brings back some classic characters and storylines. It has a lot of the elements that made the TV show so popular, like interesting alien encounters, moral dilemmas for the crew to face, and a good amount of character development for the main cast of the Enterprise.
One great 'Star Trek TNG Cause and Effect' fanfiction is 'The Loop Unbroken'. It delves deep into the time - loop concept. The characters' growth and realization within the repeating events are really interesting. It shows how they gradually figure out the anomaly and try to break free in a very engaging way.
I assume the main characters would be the regular crew of the Enterprise in Star Trek: The Next Generation, like Captain Jean - Luc Picard, Commander William Riker, Data, and others.
I think 'Imzadi' stands out as a popular one. It has a great story that many fans can't get enough of. 'Q - Squared' is also a fan favorite with its unique take on the omnipotent Q. And 'The Best and the Brightest' is popular for showing different aspects of the TNG crew's personalities and how they interact in challenging situations.
In body swap Star Trek TNG fanfiction, it often delves into the relationships between characters. A body swap between Riker and Troi could bring out new dynamics. Riker might discover things about Troi's empathic abilities from a very personal level, and Troi could experience the pressures of being in a command position like Riker. It also allows fans to play with the characters' personalities in new and unexpected ways.
One great 'Star Trek TNG Hurt Comfort' fanfic is 'Healing Bonds'. It focuses on Data's struggle to understand human emotions during a difficult time on the Enterprise. The story does a wonderful job of showing how his crewmates help him through it.
Data in fanfiction can be part of many different storylines. For example, he could be involved in a time - traveling adventure, or perhaps a story where he is the only one who can solve a complex scientific mystery on a strange planet. His unique abilities and his constant quest to be more 'human' give writers a lot of material to work with.
