In my opinion, Iron Man would be the toughest. He's so used to his high - tech environment. As a baby, he'd be constantly trying to tinker with things. And if he doesn't get his hands on some sort of technology - like toys with lights and buttons, he could get really fussy. Also, he's a bit of a know - it - all as an adult, so as a baby he might be really stubborn.
Probably Thor. He's used to being a powerful god. As a baby, he might be really demanding. He'd want his hammer all the time and would throw tantrums if he couldn't have it. Also, he might be used to a certain level of luxury in Asgard, so taking care of his needs could be a real challenge.
I think Hulk would be the most difficult. Even as a baby, he has that temper. If he gets angry, he could cause a lot of destruction. It would be hard to calm him down, and his super strength as a baby might still be considerable, so he could break things easily.
I think Hidan would be the most difficult. He was always so hot - headed as an adult. As a baby, he would probably be very fussy and hard to calm down. He might throw tantrums all the time and not listen to whoever is taking care of him.
In 'Avengers turned into babies fanfiction', things could get really interesting. The Avengers' base would need to be baby - proofed. Captain America as a baby might still have that sense of justice, but would express it in baby ways like crying when he sees something unfair, like someone taking a toy from another baby. Hulk as a baby might be a little ball of green anger, getting fussy when he doesn't get his way. It would be a complete change of dynamic for the whole superhero group, and their relationships would be very different as they rely on non - superhero adults or other characters to take care of them.
Iruka - sensei would be a likely candidate. He has always been like a father figure to Naruto, so he would probably step up and take care of baby Naruto.
Pepper would be a likely candidate. She has a close relationship with Tony already, so she'd probably step up and take care of him. She has experience dealing with Tony's antics, so she could handle baby Tony's needs too.
Catwoman might also step in. Despite being a sometimes - villain, she has a soft spot for Batman. She could use her cat - like skills to keep baby Batman out of harm's way. And she might find the whole situation rather amusing, but still be very vigilant in protecting him.
I think baby Groot would be the cutest. He's already so adorable in his normal form, and as a baby, he'd be even more so. Just a little sprout with big eyes.
In comics, taking care of babies often involves showing tender moments like feeding them on time and providing a safe and cozy environment.
They show him kindness and try to understand his motives. They offer support and help him find a better path.
Mercy could also be a great caretaker. She has a nurturing side as a healer. She would be able to make sure baby Junkrat is healthy and well - taken care of, using her medical skills to check on him regularly.
Well, in such a fanfiction, there could be a lot of chaos. The Akatsuki members, with their adult personalities and powers, suddenly being babies would mean they are completely helpless. Maybe their comrades would have to take care of them like babysitters. For example, Itachi, who was always so composed, would now be a crying baby in need of diaper changes and feeding.
