Well, in fanfiction, anything can be possible. Maybe it could be due to some magical cross - over event. Perhaps a powerful magic combined the different worlds of Tarzan, Elsa, and Anna, and as a result, Tarzan became their brother in this fictional scenario.
In this kind of fanfiction, the idea might stem from the creativity of the author. They might have thought about how different characters from various stories could interact if they were in the same family. For example, Tarzan's wild and nature - adapted side could contrast with Elsa and Anna's more civilized and magic - influenced lives. It could make for an interesting dynamic in the story. Maybe a time - traveling or dimension - hopping plot device was used to bring them together as family members.
Fanfiction often plays with established characters in new and unexpected ways. In this case, for Tarzan to be Elsa and Anna's brother, the author could be exploring themes like family bonds that transcend different settings. Tarzan, growing up in the jungle, might bring a unique perspective to Elsa and Anna's lives in Arendelle. He could teach them about survival in the wild, while they could introduce him to the world of magic and royalty. It's all about creating a new narrative that combines different elements from different stories.
He could go on ice - climbing adventures with Elsa. Since Tarzan is so good at climbing trees in the jungle, he might adapt well to climbing ice cliffs in Arendelle. And with Anna, he could explore the forests around Arendelle, sharing his knowledge of the wild.
In this fanfiction, perhaps Tarzan is lost in the forest near Arendelle. Elsa and Anna, out on an adventure, stumble upon him. Tarzan, being used to the jungle, could show Elsa and Anna how to move stealthily through the trees. Elsa might use her powers to create an ice bridge over a river they encounter, impressing Tarzan with her magic.
Tarzan would interact with a sense of wonder. He would likely be drawn to Elsa's grace and Anna's bubbly personality. He might communicate in his own unique way, using gestures and simple words. Elsa would be more reserved at first, but gradually open up as she sees Tarzan's pure heart. Anna would be the one to initiate most of the conversations, asking Tarzan about his jungle life.
There could be a dark spirit that has been awakened by the little brother's emerging powers. This spirit is angry at being disturbed and decides to target the little brother. It causes chaos in Arendelle, blaming it all on the little brother. As the story progresses, the little brother has to find a way to either defeat or pacify this dark spirit to save his home and family.
Well, one possible plot could be that the little brother has some unique magical abilities that are different from Elsa's ice powers. Maybe he can communicate with animals in the enchanted forest and has to use this power to save the kingdom from a new threat.
In this kind of fanfiction, it might be that there's a special crossover event. For example, perhaps there's a powerful entity that messes with the fabric of reality and combines elements from the Naruto and Dragon Ball universes in a strange way. This could lead to Naruto being Trunks' dad in this fictional setting. It's all about the creativity of the writer who wants to explore new and unexpected relationships between different fictional worlds.
It becomes deeper. They become more reliant on each other for emotional support. Since they are both going through the same experience of pregnancy, they can share their fears, joys, and concerns. For example, they might talk about how their bodies are changing and how they will raise their children.
Anna could be extremely excited and helpful. She might be constantly by Elsa's side, getting things for her, and sharing in the joy of the pregnancy. Anna could also be a bit overprotective, which could lead to some comical moments in the story.
To develop their relationship in fanfiction, you could explore their different interests. Anna is more outgoing and loves adventures, while Elsa is more reserved. Have Anna introduce Elsa to new things like a local festival in a neighboring village. At the same time, Elsa can share her knowledge of magic with Anna. Also, create scenarios where they have to communicate better. For instance, if there's a misunderstanding between them caused by a new character in Arendelle, they need to talk it out to resolve it. This would deepen their understanding of each other.
Their relationship can be developed through shared experiences. For instance, they could go on a journey together to explore a new part of their kingdom. During this journey, they would face challenges like difficult terrains or wild animals. As they overcome these challenges side by side, their trust in each other would grow. They could also have heart - to - heart conversations at night, under the stars, where they open up about their fears and hopes.
