Perhaps the story is about the baby growing up in a world where everyone has high expectations. The baby might feel pressured to be as heroic as Mario and as gracious as Peach. The fanfiction could explore the baby's journey of self - discovery, trying to find its own identity while living in the shadow of its famous parents.
Well, the story could be about the joys of raising their baby in the Mushroom Kingdom. It might show Mario teaching the baby how to jump over obstacles, just like he does in his adventures. And Peach could be teaching the baby about kindness and ruling the kingdom someday.
It could be about various things. Maybe it's a fictional story that features Baby Mario and Baby Peach going on adventures together in the Mushroom Kingdom. They might face challenges like dealing with Bowser's minions or finding power - ups.
There could be a new, unknown villain. Maybe a dark force from a far - off land that senses the power of Mario and Peach's baby and wants to use it for its own dark deeds. This villain could bring in new elements to the fanfiction, like different types of magic or strange creatures that the Mario characters have to face to protect their baby.
Wart could also be an antagonist. He might try to take over the Mushroom Kingdom where Baby Mario and Baby Peach live. He could send his minions to stop the two from getting help or finding special items that can defeat him.
One idea could be that Mario and Peach's baby has special powers inherited from both of them. For example, the baby could have Mario's jumping ability and Peach's ability to communicate with nature. This would lead to all sorts of adventures as the baby discovers its powers while growing up in the Mushroom Kingdom.
One idea could be that Baby Mario and Baby Peach go on a magical adventure through the Mushroom Kingdom, encountering new and strange creatures along the way. They might have to work together to solve puzzles to reach a special power - up that can save the kingdom from a new threat.
Some of the other characters in the Mushroom Kingdom, like Yoshi, could become like an older brother or protector to the baby. Yoshi might give the baby rides and teach it about the different areas of the kingdom. The Koopa Troopas, on the other hand, might be a bit more wary. They might see the baby as a future threat to their more chaotic ways, but at the same time, they could also be curious about this new addition to the Mushroom Kingdom.
A cute moment could be when Mario brings Peach a little flower he found during his adventure. Peach takes it with a big smile and puts it in her hair. Mario then blushes and says, 'You look even more beautiful, Princess.'
One possible plot could be a grand wedding ceremony. Mario and Peach would invite all their friends from the Mushroom Kingdom, like Toad and Yoshi. They would have a beautiful ceremony in the castle gardens, with Peach in a stunning white dress and Mario in his best suit. After the ceremony, they could go on a honeymoon to a new, magical land that has been discovered in the Mushroom World.
A common theme is adventure. Since the Mario franchise is known for its action - packed adventures, fan fictions often send Mario and Baby Peach on quests. Another theme is friendship, showing how they support each other in different situations.
