Obviously, Harry is a great character to pair with them. His heroic nature and his knack for getting into (and out of) trouble can create a lot of interesting storylines. Hermione could also be a good addition. Her intelligence would complement Padma's, and they could have some great academic discussions. And Ron, with his humor and loyalty, could add a different dynamic to the group, especially when paired with Parvati.
Draco Malfoy could be an unexpected but interesting character to pair with Padma and Parvati. If the fanfiction is about post - war reconciliation, Draco's complex character could add a lot of depth. He might start off as a reluctant ally but eventually grow to respect and befriend Padma and Parvati. Additionally, Cedric Diggory, if the story is set during his time at Hogwarts, could be a great character to pair with them. His popularity and charm could create some interesting social and magical storylines with Padma and Parvati.
In fanfictions, Neville could be an interesting character to pair with Padma and Parvati. Neville has his own growth arc in the original series, and when combined with Padma and Parvati, they could form a trio that focuses on herbology projects or battles against dark magic related to plants. Luna could also be a great pairing. Her unique perspective on the wizarding world would contrast and blend well with Padma and Parvati's more traditional Hogwarts - educated views.
One interesting fanfiction could be about Padma and Parvati's adventures at Hogwarts during a year when Harry is also involved in some mysterious events. They might team up with Harry to solve a riddle that has been plaguing the school. Another could be a story where Padma and Parvati use their unique skills, perhaps Padma's intelligence and Parvati's charm, to help Harry in a wizarding tournament - like a different take on the Triwizard Tournament where they play a more significant role.
I'm not sure of specific names, but often you can find great authors by looking at the reviews and ratings on fanfiction websites. Those with high ratings and positive reviews are likely to be good. You can also ask in Harry Potter fan forums for recommendations.
In a fanfiction, Harry's character can be developed through his relationships with Padma and Parvati in relation to the lemon. For example, if the lemon has some sort of healing power, Harry could be the one who is initially skeptical but then learns to trust in the power of the lemon and the wisdom of the girls. Padma could be developed by showing her meticulous research on the lemon's properties, and Parvati could be developed as the one who is most in tune with the emotional and spiritual aspects of the lemon's magic.
In a Padma and Parvati Patil lemon fanfiction, the story could revolve around a mystery that only they can solve. It could be something related to an ancient Indian magic that has found its way into Hogwarts. Their connection to each other would be crucial in unravelling this mystery. The 'lemon' aspect might add a bit of a romantic or spicy undertone to their relationship, perhaps as they grow closer while facing the challenges of this mystery.
One interesting story could be about Padma and Parvati's adventures at Hogwarts that Harry gets involved in. Maybe they discover a secret chamber together and have to use their combined skills and Harry's courage to get out of it.
In fanfiction, their characters might be given more in - depth backstories. For example, we could learn more about their family life outside of Hogwarts. Maybe Parvati has a special relationship with an elderly relative who is a powerful witch, which wasn't mentioned in the books.
A fanfiction could center around Parvati and Padma forming a secret club at Hogwarts. Harry Potter discovers it by accident and they initially don't trust him. But as time goes on, they realize they can all work together to combat a new threat to the school, like a group of dark wizards trying to infiltrate Hogwarts under the guise of new students.
It could show their daily lives at Hogwarts in a more detailed way. We might see them getting ready for classes, sharing secrets in their dormitory. The 'lemon' part could imply some sort of gentle romance, like a first crush or a secret admirer situation between them.
One possible plot could be a story where Harry, Padma, and Parvati are working on a magical potion in Hogwarts, and lemon is a key ingredient. They face challenges in finding the perfect lemon, which has special magical properties. Along the way, there could be some friendly rivalries between Padma and Parvati as they both try to contribute the most to the potion - making process.
Padma herself can be a very interesting character in fanfiction. Writers can really develop her beyond just being Parvati's sister. She can be shown as a strong - willed, intelligent witch with her own dreams and desires, especially in relation to Harry.
