There's also 'Teenage Mutant Ninja Turtles: Mutant Mayhem - The Junior Novelization'. It's based on the movie and is great for fans who want to relive the story in a different format. It includes all the action and humor of the movie in a written form.
Another one could be some of the older tmnt novels that were released in the 90s. These novels often had unique storylines that explored different aspects of the Turtles' world, like their relationships with other mutants and their battles against new villains.
The 'Teenage Mutant Ninja Turtles: The Last Ronin' is quite popular. It tells a darker and more mature story of the TMNT.
One popular 'tmnt adventures graphi novels' is the one that features the origin story of the turtles in a unique and engaging way. It has great art that really brings the characters to life.
One popular type is adventure - themed tmnt x reader stories. In these, the reader often joins the Turtles on their quests in the sewers of New York, fighting against the Foot Clan. Another kind could be friendship - centered stories, where the reader becomes a close friend to the Turtles, sharing in their joys and sorrows, like having pizza parties together or helping them deal with the challenges of living in a human - dominated world.
I'm not aware of any 'abused' fanfictions in a positive or promoting way as abuse is a serious and negative topic. Fanfictions should generally focus on positive, creative and healthy storylines rather than such disturbing themes. However, if there are some that deal with this in a way to show how to overcome abuse or something similar, they would be hard to single out without extensive searching through the TMNT fanfiction community.
The characters. The Teenage Mutant Ninja Turtles are unique and have distinct personalities. Each turtle has their own quirks and skills, which makes them very appealing. For example, Leonardo is the leader, Donatello is the smart one, etc.
There's also the 'mentor - mentee' trope. If the OC is a highly skilled ballerina, she could become a mentor to the turtles in terms of grace and balance, which they can apply to their fighting. In return, the turtles can teach the OC self - defense and how to be brave in the face of danger, which is something she may lack in the ballet world.
One popular storyline could be a moment of reconciliation. Maybe they've had a huge fight, and in a moment of intense emotion, they share a kiss as a sign of forgiving each other and realizing how much they truly care about their brotherly bond. It could also be a situation where they are under some magical spell that makes them see each other in a different light and the kiss is part of that strange experience. Another idea might be in an alternate universe where the traditional brotherly relationship is redefined, and the kiss is a symbol of a new, deeper connection that they are exploring.
One love triangle scenario could involve the reader, Michelangelo and Karai. Michelangelo's positive and humorous nature might draw the reader in. Karai, on the other hand, has her own charm with her skills and mysterious allure. The reader would be caught between the light - hearted turtle and the complex female character, leading to a story full of twists and turns.
The blend of action and humor. They had really cool fight scenes with the turtles using their ninja skills, but also had a lot of funny moments. This combination made them not only exciting but also enjoyable to read. Also, they were among the first to really explore the whole concept of mutant turtles living in the sewers of New York, which was a really creative idea at the time.
I'm not sure if there are specifically popular ones with just this exact combination. However, the TMNT fanfiction community is quite large, and there could be some out there. You would need to search through various fanfiction platforms to find them.
