In some fanfictions, Eleven might get bullied because of her strange appearance and powers. For example, other kids in the story could mock her for not being 'normal' like them. They might tease her about her shaved head or the fact that she doesn't know much about the normal world.
Character consistency is key. The Eleven in the fanfic should resemble the character from the show in terms of her powers, her naivete, and her strong will. Another element is the plot. It should be engaging and not just a rehash of the show's storylines.
One interesting aspect could be the exploration of how the pregnancy would affect Eleven's character development. Given her unique background and powers, it would add a whole new layer to her story.
I'm not sure about specific 'Eleven Stranger Things' pregnant fanfiction, but you can try searching on fanfiction websites like Archive of Our Own. There are likely many creative takes on the characters in various situations there.
Her appearance also plays a part. With her shaved head and sometimes strange expressions (due to her not being used to normal social situations), she stands out and is bullied for it. For example, kids in the fanfiction might call her names related to her looks.
Well, it might refer to the never - ending mystery and adventure in 'Stranger Things'. The show is full of strange happenings and new plot twists in every season, just like a story that never ends.
