There are fan fictions that deal with Dr McCoy's emotional side. For instance, a story could be about him dealing with the loss of a patient in a very difficult situation. It shows his struggle to come to terms with the fact that, despite his best efforts, he couldn't save someone. And there are also those that show his role in diplomatic missions where his medical expertise is used to gain the trust of other species.
Another option is to check out Tumblr. There are many Star Trek fans on Tumblr who create and share fan fictions. You can search for the 'Dr McCoy' tag, and you'll get a bunch of posts related to fan fictions about him. Some of these might be short and sweet, while others could be more in - depth stories.
Well, in some fan fictions, spanking might be used as a form of discipline in the context of the Star Trek TNG universe. For example, a story could feature a character getting spanked for disobeying a crucial Starfleet rule. However, these are often creative interpretations and not part of the official canon.
One interesting plotline could be about the traveller's encounters with new and strange alien species in the Star Trek universe. Maybe they form unexpected alliances or face unique challenges.
In some fan fiction, there might be a story about the legacy of the Enterprise in the context of Star Trek Generations. For example, a young crew member discovers a hidden technology on the old Enterprise-D that has the potential to change the future of the Federation. This could lead to a whole adventure of protecting this technology from those who would misuse it.
His struggle with the ethical dilemmas of medical practice in space is also a common theme. Since he has to deal with different alien physiologies, he often faces tough decisions. In some fanfictions, this is shown through his internal monologues as he tries to figure out the best course of action.
One common theme is McCoy's friendship with Kirk and Spock. Many fanfictions explore how their relationships develop further in different scenarios. Another theme is McCoy's medical skills and how he uses them in challenging situations. For example, dealing with new alien diseases or treating injured crew members during dangerous missions.
One idea could be a united front of different Star Trek species coming together to prevent WW3. They might use their advanced technology to broker peace on Earth.
One idea could be that the Covenant from Halo discovers the Federation in Star Trek. The different technologies and cultures would clash in really exciting ways. Maybe the Covenant would see the Federation's peaceful coexistence ideals as a threat to their religious beliefs.
One idea could be exploring a new type of hyperdrive malfunction that sends the starship into an uncharted and dangerous part of the galaxy. Another could be a story where a young engineer discovers a way to enhance the hyperdrive's efficiency but has to face opposition from the traditionalist crew members. A third idea is a race against time where the hyperdrive is the only hope to reach a distant planet before a natural disaster wipes out all life there.
One interesting storyline could be the USS Condor encountering a new and mysterious alien species. Maybe they initially misinterpret each other's intentions, leading to some tense moments before they figure out how to communicate and cooperate.
