Well, one possibility is that he could be taken in by a kind family. They might not know who he really is and just think he's an ordinary baby. They would care for him, feed him warm milk, and keep him cozy in a little crib. As he grows up, he might start to show signs of his magical powers, like making little ice crystals form on his crib railing when he's excited or sad.
He could also end up in a magical place full of other mythical creatures as a baby. The other creatures would be curious about this strange little being. Some might be afraid, thinking he could bring an unexpected winter to their land. But others, like the friendly sprites, would play with him, and as he grows, he would learn from them how to control his powers better in this new form.
Well, one possibility is that the Guardians will immediately start a search party. North, with his knowledge of all the hidden corners of the world, would lead the way. They might find some clues in the form of ice crystals that Jack unknowingly left behind during the kidnapping. Another thing could be that Pitch tries to turn Jack to his side by showing him the 'dark side' of things, like how humans can be cruel and ungrateful. But Jack, being the positive spirit he is, would resist Pitch's temptations.
Well, if Sasuke turns into a baby in a fanfiction, one thing that could happen is that his friends would have to take care of him. Naruto, for example, might be really confused at first but then would become super protective. He'd probably try to feed Sasuke all kinds of strange foods that he likes, like ramen, not realizing that babies can't eat that yet. And Sakura would be all motherly, trying to keep Sasuke clean and making sure he's warm.
Well, one possibility is that the other superheroes would have to take care of him. They might be really confused at first. Iron Man could be trying to figure out how to reverse the situation with his high - tech gadgets. Captain America would probably be more focused on protecting the baby Spider - Man from any potential threats.
Well, one possibility is that Naruto would be extremely protective. He has always cared for Hinata in some way, and with her as a baby, he'd likely take on a very nurturing role. Maybe he'd try to find a way to turn her back, or he'd just enjoy taking care of her like she was his own little sister or something. He could introduce her to all his friends in the village as his 'new little friend' and they'd all be super curious about how this happened.
In terms of the story's development, it could lead to a whole new arc. Naruto's transformation into a baby girl could be a sign of a greater threat to the ninja world. It might be related to some ancient curse or a new enemy's plot. And as he tries to figure out how to turn back, he would have to rely on his friends and his own inner strength in a different way than before.
Well, if Jack Frost were to join the Avengers, it could be really cool. He has the power to control ice and cold, which would add a new element to the team's abilities. Maybe he could create ice barriers to protect the team during battles or freeze enemies in their tracks. His powers could also be useful in rescue missions, like creating ice bridges or platforms in dangerous situations.
Well, in such a fanfiction, Jack Frost could bring his icy powers to the Avengers. Maybe he'd help them fight against a new villain who has a weakness to cold. He could freeze the bad guy's weapons or create ice barriers for the Avengers to take cover behind.
Perhaps Jack Frost would initially be seen as a threat by the Avengers. After all, he has the power to control ice and snow, which could be misinterpreted. But then they realize he's on their side and they start to learn from each other. The Avengers could learn about the magic behind Jack Frost's powers, and Jack Frost could learn about teamwork from the Avengers.
It's possible that his powers would be more erratic. As a baby, he doesn't have the control he has as an adult. So, his ice - making abilities might go off randomly. For example, he could accidentally freeze the water in a nearby pond just by being near it while having a little tantrum. But as he grows and learns about his powers again, he would start to gain more control over them.
Well, perhaps the story could start with Wolverine waking up one day as a baby. He would be confused and unable to communicate in his usual way. His friends would have to figure out how to feed him and keep him safe. Since he still has his mutant healing factor, he might be a very resilient baby, getting into all sorts of scrapes and coming out unharmed.
