There is no obvious relation between them as'shenzi banzai' is an unknown term (to me at least) and 'ed fanfiction' is a type of fan - created writing. Unless'shenzi banzai' is a very specific part of a particular fandom that also has 'ed fanfiction' related to it, but without more context, it's hard to say there is a relation.
The encounter between Shenzi, Banzai, Ed and the human might start off as a misunderstanding. The hyenas think the human is encroaching on their territory, and the human is just trying to find his way through the wild. As they face off, there's a moment of tension. However, the human makes a friendly gesture, like sitting down and showing he has no intention of harm. Shenzi, the leader, decides to approach first. Banzai and Ed follow her lead. From there, a unique friendship could develop as they share their experiences in the wild with the curious human.
I'm not entirely sure what'shenzi banzai' specifically refers to as it's not a very common known term. Regarding 'ed fanfiction', 'fanfiction' is fictional writing by fans based on existing works. However, 'ed' could stand for various things, like 'editorial' or it might be an abbreviation specific to a certain fandom or community. Without more context, it's hard to define precisely.
They could have a lot of comical interactions. For example, Ed's strange behavior might confuse the human at first. The human might think he's sick or something. But then as they get to know each other, they find it endearing. Shenzi could be the voice of reason among the hyenas, trying to keep Banzai from getting too overzealous around the human.
The fanfiction could center around the human getting lost in the savannah where Shenzi, Banzai and Ed live. At first, they see the human as a strange and potentially dangerous creature. However, as time passes, they notice the human is scared and alone. Ed might be the first to approach the human out of curiosity. Shenzi and Banzai would follow, and gradually they all realize they can help each other survive in the wild.
It could be the human. Since the story is about them befriending Shenzi, Banzai and Ed, the human's perspective could be the main focus. Their journey of understanding the animal world and building a relationship with these characters could drive the story forward.
One possible storyline could be Shenzi meeting a character named Lemon who has some special powers. Maybe Lemon is able to communicate with the spirits of the Pride Lands, and Shenzi, being curious, tries to use this to her advantage in the hyena hierarchy. For example, she could try to get information from Lemon about where the best prey is located so that she can lead her hyena pack more effectively.
Shenzi is a key figure among the hyenas in The Lion King. Her role is mainly to support Scar's rule. She and the other hyenas are brought in by Scar to help him take over from Mufasa. Shenzi is the one who often communicates with Scar on behalf of the hyenas. She is also involved in the events that lead to Simba's exile. Without her and the hyenas' support, Scar would not have been able to hold onto power for as long as he did.
Shenzi is one of the hyenas in The Lion King. She is a rather devious character. She teams up with Scar to take over the Pride Lands. Shenzi and her fellow hyenas are often seen as the villains. They cause chaos and help Scar rule with fear during his short - lived reign. They also play a part in Simba's exile as they are present when Scar frames Simba for Mufasa's death.
