A big challenge would be their different approaches to problem - solving. Goku is more likely to jump into a fight head - on, using his martial arts and raw power. The Kryptonian woman, on the other hand, might be more strategic, relying on her knowledge of Kryptonian technology and her ability to analyze situations. This could lead to conflicts between them when they face an enemy. For example, Goku might want to rush in and attack, while she wants to set up a trap or find a more diplomatic solution. Their relationship would need to overcome these differences in order to be successful.
The language barrier could be a challenge. Goku speaks his own language, and although he can communicate with others on Earth, the Kryptonian woman might have a completely different language. They would need to find a way to communicate effectively, perhaps with the help of some sort of translation device or learning each other's languages. Another challenge could be the expectations of their respective communities. Goku has his friends and family on Earth who might be wary of this new relationship, and the Kryptonian woman might have her own set of people (if there are any other Kryptonians left) who have different views on inter - species relationships.
One possible plot could be that Goku, during one of his intergalactic travels, lands on a planet where he meets a Kryptonian woman. They initially start as sparring partners, testing each other's strength. As they spend more time together, they learn about each other's cultures. Goku teaches her about the Saiyan ways, like the importance of training and the concept of Super Saiyan forms. She, in turn, shows him some of Krypton's advanced technology that survived its destruction. Eventually, they team up to face a common enemy that threatens both their home planets in a way.
A lot of these fanfics also deal with the idea of protecting the universe. Both Goku and a female Kryptonian are powerful beings capable of great things. So, they might team up to fight a common enemy that threatens the entire universe. This theme gives the writers a chance to create epic battles and show the combined strength of these two characters, while also exploring their relationship in the context of a high - stakes situation.
You can try searching on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net.

Just use the search function and type in relevant keywords like 'Goku x Fem Kryptonian' to see if any such fanfics are available.
A human male detective could be investigating strange occurrences in the city when he encounters a Kryptonian female superhero. They start working together to solve crimes and protect the city. Along the way, their relationship blossoms as they discover they have more in common than they thought, like their strong sense of justice.
The existing relationships in the Dragon Ball series can be a hurdle. Goku is married to Chi - Chi, and Bulma is with Vegeta. So, the writer has to find a way to make the Goku x Bulma relationship believable without completely disregarding the established pairings.
It can be a relationship of mutual respect. The Kryptonian respects Batman's intelligence and determination despite being a mere human. Batman respects the Kryptonian's power and their sense of justice. They might have different approaches to solving problems, but they recognize the value in each other's methods. For instance, when facing a powerful villain, Batman would come up with a strategic plan while the Kryptonian uses their powers to execute it.
I'm not sure if there is an existing 'goku and wonder woman lemon fanfic'. Fanfics can cover a wide range of pairings, but this particular one might be quite rare or not commonly known. It also depends on the specific fanfic communities and platforms you search on.
There could also be a social perception issue. Society sometimes has certain expectations or stereotypes about relationships with large age gaps. Friends and family might not understand or approve, which can put pressure on the relationship. Another aspect is that there may be differences in cultural references and interests. Older women might have grown up with different music, movies, and social trends, which could create some communication gaps at times.
One challenge is power - scaling. Kryptonian powers are extremely powerful, and in the Marvel universe, there are already many powerful characters. You need to find a balance so that your Kryptonian OC doesn't seem overpowered. Another issue is fitting their backstory into the existing Marvel lore. Since Kryptonians are from DC, it can be difficult to make their origin story mesh well with the Marvel continuity.
One challenge could be the difference in energy levels. Older women might not have the same stamina as younger partners. For instance, in a relationship between a 20 - year - old and a 40 - year - old woman, the younger man might be more active and want to engage in more physical activities, which could be tiring for the woman.
