I'm not sure specifically which 'bleed for this real story' you are referring to. It could be a movie, a book, or some other form of media. There's not enough information to give a detailed account.
One grade 4 brain bleed story could be about a young athlete. He was playing a very rough sport when he suddenly got hit hard on the head. At first, he just felt a bit dizzy but then he started having severe headaches. Later, it was found that he had a grade 4 brain bleed. The doctors had to perform emergency surgery to relieve the pressure in his brain.
I'd say it is. It offers a unique take on the superhero theme and has some unexpected twists. However, if you're not into that kind of story, you might not find it as appealing.
This fanfic could potentially focus on how the idea of 'the color you bleed' relates to the magical and colorful world of MLP. It might be a creative exploration of a character's essence, where the color they bleed represents something deeper, like their true self or their most powerful aspect. For example, if a character bleeds a certain color, it could symbolize their loyalty or kindness, which are important traits in the MLP world.
