Yes, in the vast world of fanfiction, there are all kinds of creative and out - of - the - box stories. Some fans like to explore unusual relationships and scenarios, so it's possible that there is such a fanfiction out there. However, it goes against the original canon of the Dragon Ball series in many ways.
No. This kind of content involves vulgar and inappropriate elements. Goku is a well - known character from the Dragon Ball series, and creating such fanfiction is disrespectful to the original work and not suitable for public consumption.
There could be some fanfiction out there that involves Goku in some unexpected situations, but when it comes to 'hard' and 'pregnant' in relation to Goku, it's not a common theme. Most Goku - related fanfiction focuses on his battles, power - ups, or relationships in a more traditional sense within the Dragon Ball universe. So, it's less likely to find this particular combination.
Another theme could be the challenges Goku faces during the pregnancy. Given that he's a powerful Saiyan, being pregnant might bring out different physical and emotional aspects that are not typically associated with his character. It could also involve how he balances his training and the impending arrival of the baby.
There may be such fanfics in the vast world of fan - created content, but it often goes against the original storyline's intended relationships in the Dragon Ball series. In the official story, Goku is married to Chi - Chi, not Bulma.
One possible plotline could be Goku's reaction to Chichi being pregnant. Maybe he's initially clueless about how to handle it and has to learn about taking care of a pregnant wife. Another could be Chichi preparing for the baby's arrival while Goku is off training but trying to be more present for her.
Well, it could be about Goku facing a really tough situation ('hard') while his partner is pregnant. Maybe he has to protect his pregnant loved one from a new and powerful enemy in the Dragon Ball world.
One possible plotline could be the challenges she faces while still being a powerful fighter during pregnancy. Maybe she has to deal with villains who see her as vulnerable.
It could be Frieza. Frieza might see Goku having a family as a weakness and try to take advantage of the situation to finally defeat Goku once and for all.
One possible plot could be that Goku and Caulifla accidentally get exposed to some strange energy during a battle that causes an unexpected pregnancy. They then have to deal with the shock and figure out how to balance their warrior lives with the upcoming new life.
