The Doctor Who animated stories usually have creative plots and unique visual styles. They often bring back beloved characters and expand on the existing lore of the series.
According to what I know about web novels, the longest series of anime is Naruto. This anime was started in 2007 and is still being published. It updated one episode a week and had already updated more than 1500 episodes. As a result, Naruto had been in series for more than 10 years and had become a very popular anime.
Obviously, Superman is one of the main characters. There might also be some characters from his supporting cast like Lois Lane or Jimmy Olsen who could be involved in the story.
The fanfiction often explores their unique relationship dynamics and adventures in this specific series. There might be creative takes on their interactions and the challenges they face together.
It ties in with the series by building on existing storylines and adding more depth to the 'Doctor Who' universe. It might introduce new elements or offer alternate perspectives on familiar events.
Hal Jordan is often a popular character. He's a well - known Green Lantern in the main series, so he's frequently featured in fanfiction. Writers like to explore his character further, like his relationships with other Lanterns or how he handles different threats.
Obviously, Superman himself is a very popular character. He is the center of the series and in fanfictions, his different powers and how he uses them in new situations are often explored.
