Well, it's hard to say who the 'best' is as it depends on personal taste. But some popular authors might be those who have a deep understanding of the characters. They can capture Keith's complex personality and the mystery of the Black Lion really well.
One common theme is loyalty. The stories often show how Keith and the Black Lion are loyal to each other no matter what challenges they face.
There might be a fanfiction where Keith and the Black Lion go on a special mission together that isn't shown in the original. They could face a unique enemy and have to rely on their bond to succeed. For example, they might encounter a powerful alien force that can disrupt their mental connection, and they have to find a way to overcome it.
A lesser - known but very talented author is 'KryptonianChirp'. This author likes to put Superman and Black Canary in unexpected situations, like in a world where all superpowers are switched. Their fanfictions are full of humor and interesting twists. They often use the characters' personalities to drive the story forward, making their works quite engaging.
