Perhaps there could be a plot where an ancient prophecy or some sort of supernatural force is at work. This force has chosen Alec to carry a special child, and Magnus, with his powerful magic, is the one who enables this to happen. The story could then be about their journey to understand the purpose of this pregnancy, protect the unborn child from those who might want to harm it, and also about their own relationship growing stronger as they face these challenges together.
Another plotline might be that in a world where the laws of nature are different for certain characters, Magnus and Alec decide to have a child in this unique way. The story could then focus on how they deal with the reactions of their friends and family, and also the challenges of Alec's pregnancy, like his changing body and emotions. It could also involve them preparing for the arrival of the baby, from choosing a name to setting up a nursery.
There might be some. Some fanfiction authors might explore the concept in a more platonic or magically - unique way that doesn't involve adult themes. You could start by looking on fanfiction platforms and filtering for the appropriate ratings and tags to find such family - friendly versions.
I'm sorry, but male pregnancy is a rather non - traditional and often not part of the original canon in most stories. However, you can try searching on fanfiction - specific websites like Archive of Our Own. Just type in the relevant tags such as 'Magnus' and 'Alec' and see if there are any creative takes on their relationship that might be similar to what you're looking for.
Some fandom - specific forums or communities might also have such fanfictions shared. For example, if there is a dedicated forum for the series that Alec and Magnus are from, it could be a good place to search. You might need to register and become a member of the community to access all the available fanfictions though.
One common way could be through using his magic in a subtle way. For example, he might use magic to create situations where Alec has no choice but to follow his lead. Maybe he makes it seem like the only option for Alec to protect his friends or family is to do what Magnus wants.
In fanfiction, if Alec and Magnus had a daughter getting pregnant, it could be a very emotional and complex storyline. It might involve themes of family support, dealing with unexpected situations, and the young character's growth. Maybe she'd face challenges like how to balance her own dreams and the new responsibility.
One possible plotline could be that it's the result of some strange magic or alien technology. Maybe an enemy uses a device on Goku as part of a plan to weaken him or create chaos. Another could be a more comical take where Goku accidentally ingests something that causes this unusual situation.
One possible plotline could be the chaos and shock that spreads throughout the ninja world when the news gets out. There would be reactions from their friends and enemies alike. Another could be Naruto and Karin trying to figure out how to handle the situation while also dealing with their own feelings for each other.
One possible plotline could be Sasuke discovers he's pregnant while on a solo mission. He then has to figure out how to deal with this situation while also hiding it from his enemies. Another could be that it's the result of some sort of magic or experimental jutsu gone wrong. He then has to face the reactions of his friends and family, especially Naruto, who might be shocked but also supportive.
A possible plotline could be centered around Severus seeking help from unexpected sources. Maybe he turns to some of the more neutral or even good - aligned wizards and witches for advice or assistance, since he can't rely on Voldemort or the Death Eaters completely. The pregnancy could also be a catalyst for Severus to re - evaluate his life and his actions. He might start to question his past decisions and try to find a way to create a better future for himself and the unborn child, all while dealing with the stigma and danger associated with such a situation in the wizarding world which is full of secrets and power struggles.
He may also try to reason with Magnus or the kidnappers. Alec is a smart guy, so he might try to find a way to get out of the situation through dialogue. He could point out the negative impacts of their actions on everyone involved.
