One idea could be a story about a super mutant who starts to regain some of their human memories and tries to reconnect with their former life. They could struggle with the conflict between their mutant instincts and their human emotions.
A story could focus on a human scientist who befriends a super mutant and tries to understand how they were once human. Through their friendship, the scientist uncovers secrets about the mutation process and attempts to find a cure. This would involve a lot of character development and exploration of the relationship between humans and mutants.
You can give them distinct physical features. For example, a super mutant might have an extra set of eyes due to the mutation, but these eyes could have a special power like seeing in the infrared spectrum. This would make the character stand out.
Often in fan fiction, super mutants that were once humans could be the result of genetic manipulation gone wrong or a secret government project gone awry.
One idea could be creating an OC (original character) who has a unique power related to nature, like being able to control plants. They could join the New Mutants and have to learn to control their power while also dealing with the group dynamics. Another idea is an OC with teleportation abilities but has a fear of getting lost in the teleportation process. They would have to overcome this fear while helping the New Mutants on their missions.
Another plot could involve the 'not - quite - human' character forming an unlikely friendship with a human. Through this relationship, they both learn about acceptance and the differences between their worlds. For example, the human could teach the non - human about things like music or art, while the non - human shows the human a different perspective on life.
One idea could be Gumball and Darwin as humans starting a new school and having to deal with the typical high - school dramas like popularity contests and bullies. Another could be the Wattersons going on a road trip as humans and the various adventures they have along the way. Maybe Gumball as a human gets a part - time job and has to balance work, school and his family life.
One idea could be a human mechanic who discovers Megatron in a damaged state and tries to repair him while hiding him from other humans and Autobots. This could lead to a complex relationship where Megatron starts to question his views on humans.
One plot idea could be human Kirby in a high school setting, dealing with normal teenage problems while also having his Kirby - like powers. For example, trying to hide his ability to inhale large objects from his classmates.
One idea could be a Khajiit and a human teaming up on an adventure. They might be searching for a lost magical artifact. The Khajiit's natural stealth and the human's strategic thinking could combine to overcome various obstacles like traps and monsters.
One plot idea could be that Hermione is a powerful elf with ancient magic knowledge. She uses her elven abilities to solve mysteries in Hogwarts that normal humans couldn't. Another could be that she's a magical being from a different dimension, and she has to hide her true form while trying to fit in at Hogwarts. Maybe she's a phoenix in human disguise, and she shows her phoenix powers at crucial moments to save her friends.
A great plot idea could be that a group of humans and snakemen are forced to live together on a strange island after a great cataclysm. They start off distrusting each other, but as they face various challenges like finding food and shelter, they gradually learn to work together. There could be a young snakeman and a young human who become friends and are the key to bringing their two groups closer.
