my universe

It's possible. The Harry Potter universe is so vast and popular that all kinds of unique fanfics are written. Maybe someone has combined it with 'Are You My Mother'.

In novels, the universe beyond the universe is often referred to as the outer universe because this term is often used in literature to describe the universe or world beyond human understanding. The concept of outer universes usually appears in fantasy or science fiction because these works usually explore different cosmic forms and worldviews. In these works, the outer universe may be an unknown, mysterious realm that we cannot understand, or a world ruled by other races or forces. The outer universe may also be a parallel universe that is different from our real world. These universes may have different laws and rules, and we may only be an insignificant existence among them. Therefore, the outer universe is a common concept in literature. It represents the unknown realm beyond our understanding, and it can also represent different forms of the universe and worldviews.

It's not straightforward to determine. The concept of 'largest' for a fictional universe depends on various factors like the breadth of the world-building, the number of story arcs, and the depth of the lore. So, it's difficult to claim that the Dune universe is the largest without a detailed and comprehensive comparison with others.

One idea could be that the female Naruto Uzumaki has a quirk similar to her chakra control in the Naruto world. She could use it to perform amazing physical feats like super - speed and enhanced strength. She might join U.A. High School and form strong friendships with characters like Deku. Her spunky and determined personality would make her stand out among the other students.

Goku could be seen as an alien with an extremely powerful 'Quirk' in the My Hero Academia world. His Saiyan abilities like flight, super strength, and energy blasts could be considered a new type of Quirk. He would likely stand out a lot and attract the attention of both heroes and villains.

It can be integrated through a magical artifact. For instance, a mysterious relic is discovered in the My Hero Academia world that bestows the Sharingan upon those who touch it. This could lead to a race among heroes and villains to obtain it.

One way it could fit is by having a character with a quirk that allows them to mimic the Sharingan's abilities. For example, they might be able to copy other heroes' or villains' quirks in a similar way to how the Sharingan can copy jutsu in Naruto. This would add a whole new level of strategy and intrigue to the My Hero Academia world.

Twilight Sparkle is often still a popular character in alternate universes. Even in different settings, her intelligence and leadership qualities can be explored in new ways. Rainbow Dash is also popular as her speed and bravery can be adapted to various scenarios, like in a space - themed alternate universe where she could be a star - racer.

In a fanfiction scenario, the Hulk might be a result of a secret experiment by the League of Villains to create an ultimate weapon. But instead of being fully controllable, he breaks free and becomes a wild card in the power dynamics of the My Hero Academia world. His presence would disrupt the existing balance between heroes and villains as everyone tries to either control or destroy him.

First, get to know the original 'across the universe' work really well. Understand the characters, the setting, and the main plot. Then, think of an interesting idea that can expand on it. It could be a 'what - if' scenario, like what if a certain character made a different choice at a crucial moment. After that, start writing down your ideas in an outline. Don't worry too much about grammar at first, just focus on getting your story ideas down.
