The relationship can develop through mutual support during the pregnancy. Yami could be very protective of Yugi, always making sure he's comfortable and has everything he needs. Yugi, in turn, can rely on Yami and show his gratitude, which deepens their bond.
Their friends might be initially shocked. Some might be very supportive right away, like Joey who could be constantly checking in on them and offering to help. However, others like Kaiba might be more skeptical or even a bit dismissive at first, thinking it's some kind of strange joke or ploy.
One popular trope is the 'power transfer' where Yami Yugi imparts some of his ancient powers or knowledge to Yugi in a fanfic. Another is the 'alternate universe' trope, like a modern-day setting where they are regular high - school students instead of duelists. And the 'bond - strengthening' trope is also common, showing how their relationship deepens through various challenges.
One possible plotline could be the challenges they face in their daily lives while being pregnant. They might have to deal with the reactions of their friends and family. Another could be how they support each other through the physical and emotional changes. For example, Yugi might be more worried about the future, while Yami is more calm and reassuring.
In non - adult versions, a common element is the reimagining of the concept of 'pregnancy'. It might not be a biological pregnancy but rather a spiritual or emotional one. So, there could be a lot of talk about their souls merging or a new entity being formed within their shared bond. Another element is the use of alternate universes or time - travel scenarios. For instance, they might travel to a different dimension where the rules are different and this kind of situation can occur. And the characters' reactions to this abnormal situation, like Yugi's confusion and Yami's determination to figure things out, are often explored.
There might be. Some fanfic writers like to take the relationships between characters in unexpected directions without delving into adult themes. They might write a story where Yami and Yugi have a special connection that leads to a situation that can be interpreted as a 'pregnancy' in a very symbolic or metaphorical sense. It could be about their bond growing so strong that it creates a new 'life' in the form of a powerful alliance or a new aspect of their relationship.
A common theme is the power of their friendship. Their bond is often explored as something that can overcome great obstacles. Another theme is the mystery surrounding Yami's past and how Yugi helps him to uncover it. Also, the idea of their combined strength in dueling is frequently seen.
Once upon a time, Yugi was exploring an ancient tomb when he accidentally awakened Yami. Yami was drawn to Yugi's kind heart. As they spent more time together, they realized they had a deep connection. Yugi taught Yami about the modern world, and Yami protected Yugi from various dangers. Their love grew gradually, like a flower blooming in a secret garden.
I'm not sure specifically as there could be many interpretations. It might be a fan - created story where Yami, perhaps in a dark or complex situation, causes harm to Yugi, either physically or emotionally. It could explore themes like inner conflict, power struggles within their relationship.
Maybe the baby is a key to a powerful spell. Yami Yugi discovers the baby and soon realizes that there are dark forces after it. So, he teams up with his friends to figure out the mystery behind the baby and how to keep it out of the wrong hands. They have to face many challenges along the way.
