One common theme is her struggle for identity. Since Goku is so well - known, she often has to find her own place in the world. Another is family bonds, showing how she relates to Goku and their other family members.
Another option is to check out some independent fanfiction blogs. Some fans create their own blogs to host and share their fanfiction works. You can try searching for relevant keywords on search engines and see if you can stumble upon these blogs. But be aware that the quality and content can vary greatly on these individual blogs.
One popular trope is the 'fish out of water' scenario. Goku, being from a very different and action - packed universe, finds himself in the colorful and often more peaceful world of My Little Pony. His reactions to the new environment and the ponies' way of life can create a lot of humorous and interesting situations.
Honestly, comparing the strength of anime Goku and manga Goku is tricky. Both versions have their unique strengths and challenges depicted differently, making it hard to make a clear-cut comparison.
Well, Vegeta would be a likely character. He might be initially suspicious of the female Goku. Maybe he thinks she's a threat or just can't believe there's another Goku - like being. He could be there to add some comical moments as he tries to understand the situation.
One interesting storyline could be Goku accidentally landing in Equestria. He might be confused at first by the colorful ponies and their magic. But then, he could start to learn about their way of life and use his strength to help them out, like when facing some big threats that the ponies can't handle on their own.
In general, it's a bit of a toss-up. The strength of Manga Goku and Anime Goku can vary depending on the specific arcs and battles. Sometimes, it might seem like one is stronger in a particular situation, but that could change in another.
