I think a 'grey matter short story' might focus on the concept of grey matter in the brain. It could be about a character whose grey matter is somehow special, like having enhanced cognitive abilities. For example, the story could start with a scientist discovering a way to boost grey matter function in a person, and then this person goes on to achieve extraordinary things.
One possible theme could be self - discovery. If the grey matter represents the mind, the character might be on a journey to understand their own thoughts and feelings better. Another theme could be power. If having more grey matter or different grey matter gives power, the story could be about the struggle for that power.
Crossing the Cold River was one of the lyrics of the song "Traveler from the End of the World". The lyrics described the protagonist, Zhou Zishu, leaving the northwest region and crossing the cold river after completing his mission. The lyrics used the symbolic meaning of the cold river, representing that Zhou Zishu had left in the middle of winter. This lyrics could also be used to describe Zhou Zishu's loneliness and separation from the movie Dragon Gate Flying Armor. In general, this lyric expressed the scene where the protagonist was about to leave after completing his mission.
In the 'Ben 10' series, Ben Tennyson is the main character. He has a device called the Omnitrix which allows him to transform into various alien forms. Gwen Tennyson is Ben's cousin. She also has magical abilities and often teams up with Ben in their adventures.
I'm not entirely sure specifically as it could vary greatly. 'Fanfic' stands for fan fiction, which is often written by fans of the 'Ben 10' franchise. It might focus on female characters from the series, perhaps exploring their backstories, relationships, or new adventures in a way that the official content might not have fully delved into.
Well, in a Ben Ten love story, Ben could be smitten with a girl from his school who has no idea about his secret identity as a hero with the Omnitrix. He has to balance his normal life with her and his life as Ben Ten. At first, he's really clumsy around her, not knowing how to act. But when she gets into trouble one day, Ben uses his powers as Four Arms to protect her. This is when she starts to suspect there's more to Ben than meets the eye, and their relationship takes an interesting turn.
Fanfiction should be inclusive and appropriate. When it involves elements like 'futa' which have adult connotations, it is not acceptable for general audiences. The 'Ben 10' franchise has a large fan base of different ages, and fanfiction should be made in a way that respects all fans. So, this kind of fanfiction is not suitable for all.
One popular 'Ben Ten' fan fiction could be about Ben using his alien forms in new and unexpected ways to save the world. For example, he might have to combine the powers of multiple aliens to defeat a super - powerful villain that the original show didn't feature.
