Perhaps the kid virus has some unique ability that Thrax discovers while taking care of it. This ability could be something that helps them both in their survival. For example, the kid virus might be able to detect approaching immune cells from a greater distance than Thrax. So, Thrax starts to rely on the kid virus for this special skill. And as a result, their relationship becomes more of a partnership rather than just Thrax taking care of the kid virus.
One possible scenario in this fanfiction could be that Thrax, despite being a typically 'bad' virus, has a change of heart when it comes to taking care of the kid virus. Maybe he sees something of himself in the kid virus or perhaps he's just bored and decides to take on this new role. It could lead to a lot of comical situations as Thrax tries to figure out how to be a caretaker, like trying to find food for the kid virus (even though viruses don't really eat in the traditional sense) or protect it from other threats in the microscopic world.
In the fanfiction, Naruto would be super protective. He'd use his ninja skills to keep the baby safe from any harm. For example, if there was a threat, he could quickly create a barrier around the baby using his chakra. Also, he'd be really patient, which is a bit different from his usual impulsive self when it comes to taking care of the baby.
In this fanfiction, perhaps Harry could struggle at first with the basic tasks like feeding and changing the baby. He might make mistakes but learn quickly.
Well, Harry might use his magic to make the baby laugh. For example, he could turn the baby's rattle into a little magical creature that dances around. He'd probably also be very protective, like how he was with his friends at Hogwarts.
Well, Naruto might be really confused at first. He's from a world of ninjas and suddenly has to take care of a baby wizard. He'd probably use his ninja skills to protect Harry. For example, he could set up traps around the house to keep bad guys away. And he'd surely try to feed Harry some ramen, which might be a bit strange for a baby used to wizard food.
In this kind of fanfiction, Ginny might help Harry deal with his PTSD. She could be there for him during his nightmares, offering comfort and reassurance. Maybe she cooks his favorite meals to bring some normalcy back into his life.
A great aspect could be Severus helping Harry with his emotional turmoil. Harry has a lot on his plate, and Severus, having his own troubled past, could offer some words of wisdom. He could share his experiences in a way that helps Harry navigate the difficulties of growing up in a magical world filled with danger and mystery. This would deepen their relationship and show a different side of both characters.
Harry Potter would be very cautious while taking care of the newborn Ponyta. He'd first need to understand its nature. As Ponyta is known for its skittishness, he'd have to be gentle. He might ask Hagrid for advice. Hagrid could tell him how to handle Ponyta's hooves properly or how to groom it. Harry would also need to ensure that the Ponyta is not exposed to any dark magic. He could use protective spells around its stable. And when it comes to training the Ponyta, he'd use positive reinforcement, like giving it a treat when it follows a command.
Kakashi might use his Sharingan to quickly assess Naruto's condition. He could then take the necessary steps to heal him, like getting the right medicine or using some basic medical ninjutsu if he knows any.
If Naruto has the T - virus in a fanfiction, he might initially try to hide it from his friends. He's used to facing challenges alone. But as the virus progresses, his physical abilities could start to change. Maybe he'd gain some strange new powers related to the virus at first, but then gradually lose control. His friends would eventually notice something is wrong and try to help him, but it could be a race against time to find a cure before he completely turns into a monster.
