The main characters would be the Scarlet Witch as the mother - like figure. The 'little Harry Potter' would be the central focus in terms of the story's development related to the Harry Potter elements. Then, we might see some of the Hogwarts professors. For instance, Dumbledore could play an interesting role. He might be initially cautious about the Scarlet Witch's presence in the wizarding world but then come to see the value of her protecting the young wizard. And of course, Voldemort could be a lurking antagonist, creating threats to both the Scarlet Witch and the boy she's protecting.
Obviously, the Scarlet Witch would be one of the main characters. And then there would be a character inspired by Harry Potter, probably a young boy with a lightning - shaped scar on his forehead. There could also be other characters from the Harry Potter universe like Hermione and Ron, who might interact with the Scarlet Witch and the 'little Harry Potter' in different ways.
The Scarlet Witch is the key character here as she takes on the mother role. The 'little Harry Potter' character is essential too. But we could also have some new characters created specifically for this fanfic. Maybe a magical creature that is drawn to the Scarlet Witch's unique magic and becomes a sort of helper to the duo. And then there could be a group of dark wizards who are jealous of the Scarlet Witch's power and try to use the 'little Harry Potter' to get to her, adding more conflict to the story.
Perhaps the story could revolve around the Scarlet Witch guiding this 'little Harry Potter' in learning about magic in a different way. Since she has such unique powers, she could teach him things that Hogwarts doesn't. For example, she might show him how to manipulate reality on a small scale, which would be both exciting and dangerous for the young wizard. It could also involve her using her powers to shield him from Voldemort's influence in a more direct way than Dumbledore and the Order of the Phoenix ever could.
One possible plot could be that the Scarlet Witch discovers Harry as a baby, much like how Hagrid discovers him in the original Harry Potter story. She decides to take him in and raise him, using her magic powers to protect him from the dark forces. Maybe she teaches him some of her own unique brand of magic, which combines with his natural wizarding abilities.
I'm not entirely sure if there is a specific 'Scarlet Witch mothers little Harry Potter' fanfic. Fanfic communities are huge and diverse. It could be that someone has thought of this interesting crossover and written about it. You might have to dig deep into platforms like Archive of Our Own or FanFiction.net.

Harry Potter himself could be one of the main characters, as he might be drawn into the activities of the Scarlet Knights. Hermione Granger could also play a major role, using her intelligence to help the Scarlet Knights solve mysteries or overcome obstacles. Another character could be a new student, a transfer from another magical school, who has a unique ability that makes them valuable to the Scarlet Knights.
In the fanfic, Scarlet Witch might adopt Harry Potter to give him a family he never had. She could teach him about her own brand of magic, which is different from the wizarding world's magic. This could lead to Harry having a unique set of skills and a new perspective on magic, which would be very interesting to explore in the story.
Their relationship could start with Scarlet Witch being a strict but loving mother figure. She'd be firm in teaching Harry about magic and how to control his powers. As Harry grows, he might start to rebel a bit against her strict ways, but they'd still have a deep bond.
Scarlet Witch's powers could have a huge impact. Her reality - warping abilities might make some of the magic in the wizarding world seem tame. For instance, she could change the layout of Hogwarts with a thought, which would be both amazing and terrifying to the students and staff.
In the 'Avengers Scarlet Witch Graphic Novel', Scarlet Witch is the central figure. But other key characters would be the Hulk. His brute strength and lack of full control sometimes can be a counterpoint to Scarlet Witch's more refined and complex powers. Then there's Hawkeye, who with his archery skills and down - to - earth personality can provide a different perspective. And Vision, who has a special connection with Scarlet Witch, is also likely to be an important character in the story.
Vision is an important character. He has a deep connection with Scarlet Witch. His android nature and his relationship with her add layers to the story.
Hermione could be one of the main characters. She might be the one who tries to find Harry and bring him back. She would use her intelligence and knowledge of magic to track him down, all while worrying about his safety.
