They could be teammates. Working together to achieve a common goal in the story, like saving a planet or rescuing hostages.
In a fanfiction, they could be pen pals. Little Mermaid writes about her underwater adventures to Jasmine, and Jasmine writes back about the happenings in her palace. Through their letters, they come to understand each other's worlds better. When they finally meet in person, it's like meeting an old friend. They then decide to have an exchange program of sorts, where some of Jasmine's people visit the underwater kingdom and vice versa to promote cultural exchange.
There could potentially be such fanfiction in some corners of the internet. However, it might be difficult to find as it involves a rather specific combination of characters and a particular scenario. Many fanfiction platforms have a large volume of content, but not all themes are equally represented.
One possibility is that they could be in a magical cooking competition together. Molly is a great cook, and Lockhart could be there for some comical reasons, like he thinks it will boost his popularity. Their interactions would be full of Molly's exasperation at Lockhart's vanity and his attempts to make himself look good during the competition.
Maybe they team up to solve a mystery. There's a strange occurrence in the forest that is causing some of the smaller creatures to disappear. Marceline with her vampire powers and Bonebrll with her own set of skills start investigating. They start off a bit wary of each other but as they work together, they develop a mutual respect and friendship.
One positive interaction could be Lucius respecting Hermione's magical abilities. Despite his initial prejudices, he might come to recognize her as a powerful witch. For instance, in a situation where they are both part of a magical council, Hermione presents a brilliant solution to a magical problem, and Lucius, albeit grudgingly at first, has to admit her superiority in that regard.
There probably are. Fanfiction writers often like to take unexpected pairings and turn them into unique stories that don't rely on sexual content. In a story about Fem Harry and a Death Eater, they could start as bitter enemies but then find common ground. Maybe they both have a connection to a certain magical object or a shared experience from their past that makes them form an alliance, which is a great way to create an engaging story without any sexual elements.
There could be issues related to the portrayal of relationships. If it goes against the general spirit or character development in the original source material, it might be considered unethical by some fans. For example, if it creates a relationship that doesn't fit with the established personalities and values of Scott Ryder and Drack. Also, if it contains non - consensual elements, that is clearly unethical.
Male animal trainers also have good relationships with animals. For example, a male trainer who works with dolphins. He teaches the dolphins to perform tricks through positive reinforcement methods, and at the same time, he also takes good care of the dolphins' living environment and diet.
In a non - sexual story, a male character might train a female Pikachu to be stronger. He could teach her new moves and they could practice together. This interaction is positive as it helps Pikachu grow and become more capable in battles.
They could have mentoring interactions. Rosalie, being more experienced as a vampire, could mentor Bella on how to control her new vampire instincts. This would be a practical and non - romantic way for them to interact.
