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.
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 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.
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.
One possible fanfiction could involve Data being injured during a mission on an alien planet. Maybe he was caught in a strange energy field that disrupted his systems. The crew of the Enterprise would then have to figure out how to repair him while also dealing with the potential threat of the energy field.
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.
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.
Well, from the list of Star Trek TNG novels, 'Dark Mirror' is quite fascinating. It shows an alternate universe version of the TNG crew, which is really cool to explore. Then there's 'Relics' which ties in with the original series in an interesting way, bringing in Scotty and his adventures in the TNG era. Also, 'Vendetta' has a great story that keeps you on the edge of your seat with some intense plotlines.
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.
