I'm not sure there are many official fanfictions that combine Anne Frank and Goku in such a way. However, if it were to exist, it would be a very strange and interesting crossover. Goku is a powerful Saiyan from a fictional universe of Dragon Ball, while Anne Frank was a real - life victim of the Holocaust. Their worlds are so different that it would be a huge creative challenge to bring them together in a believable story that lasts till the end of time.
In the fanfiction, Goku could sense the great despair and hope within Anne Frank. He is drawn to her and appears in her world. Goku starts by providing food and safety for Anne Frank and those in hiding using his instant transmission ability. As they interact, Anne Frank's wisdom and courage start to influence Goku. They form a bond that transcends time and space. Eventually, they work together to bring peace and hope to all of existence, remaining side by side till the end of time.
Well, it's a rather complex matter. On one hand, it can seem a bit odd to combine the tragic and real - life figure of Anne Frank with the fictional and super - powered Goku. However, if done in a respectful and educational way, it could potentially be used to draw parallels in themes like struggle and hope. But often, it might be considered inappropriate as it could be seen as trivializing Anne Frank's story.
One possible plot could be that Goku, through some sort of time - space rift, ends up in the time and place where Anne Frank was hiding. Goku, being the pure - hearted hero he is, might use his powers to protect Anne Frank and her family in secret. He could use his super strength to move things around quietly and use his ki to sense approaching danger, adding an element of safety to their hiding place.
One aspect could be the idea of survival. Goku is constantly fighting for survival in his battles, and Anne Frank was in a fight for survival in the annex. The fanfic could draw on their shared struggle for existence. But this would have to be done very carefully to avoid disrespecting Anne Frank's real - life situation.
Their interaction could be really interesting. Goku is used to dealing with powerful foes and saving the world in a more action - packed way. Anne Frank is in a situation where she has to be quiet and endure. Goku could teach Anne some self - defense moves in case they are discovered, and Anne could teach Goku about patience and the importance of the written word. She might even write about Goku in her diary, and Goku would be fascinated by this strange new thing called 'writing' that can preserve memories and thoughts.
Anne Frank's story concluded with her and her family being betrayed and arrested. Unfortunately, she did not survive the horrors of the concentration camps.
Anne Frank's writings are not a novel. They are a personal and genuine documentation of her life in hiding during that difficult time. It provides an authentic perspective.
