The Parselmouth could start to understand the emotions and thoughts of snakes more deeply. For example, they could sense when a snake is about to attack or when it's feeling threatened, not just what it says.
In a fanfiction, the ability could be developed by having the Parselmouth be able to communicate with other snake - like creatures, not just regular snakes. This could include magical serpents with unique powers and knowledge. They might be able to gain new spells or magical techniques from these creatures through their Parselmouth communication. Also, the Parselmouth could learn to use Parseltongue to influence the behavior of snakes in more complex ways, like getting a group of snakes to form protective barriers or search for hidden objects.
One way is to explore the magical interactions between them. For example, Harry could try to use his spells against Odin's divine powers and see what happens. This would add more action and tension to the story.
One way could be to expand on the character interactions. Have Harry and his friends travel through the Stargate and meet different alien species. They could use their magic in ways that surprise the aliens and vice versa. For example, the Asgard could be intrigued by the concept of magic.
One way to develop their relationship further is by showing them having deep conversations about their future. They could discuss what they want to do after Hogwarts, how they can change the wizarding world for the better. Also, they might start to understand each other's insecurities more. Hermione could open up to Harry about her fear of not being good enough sometimes, and Harry could share his concerns about living up to his reputation. This emotional sharing would bring them closer.
His assimilation ability could be developed through exposure to diverse magical environments. For instance, if he travels to different wizarding schools around the world, each with its own set of magical teachings and cultures, he gradually hones his ability to assimilate new knowledge and skills.
He could be developed by having to form an unlikely alliance with the God of Darkness. Through this alliance, Harry would learn new forms of magic that are darker and more powerful. This would change his perspective on magic and his role in the wizarding world. For example, he might start to question the strict rules of Hogwarts about 'dark' magic. He would have to navigate this new knowledge while still staying true to his friends and the values he has always held dear, which would be a great opportunity for his character to grow.
One way to develop it further is to create crossovers with other elements. For instance, bring in characters from other magical or action - based series. You could also explore different time periods. What if the Power Rangers landed in the past of the Harry Potter universe? Another aspect could be to focus on character relationships. Maybe a Power Ranger and a Hogwarts student fall in love and they have to navigate the differences between their two worlds.
Her character can be developed further by emphasizing her magical abilities. Since she comes from the Gaunt family, she likely has a strong magical lineage. Fanfiction could explore her learning and mastering of spells that were perhaps lost in the family or unique to her bloodline.
One way is to introduce a conflict related to his love for 'posin' fanfiction. Maybe the other characters don't understand his fascination and try to stop him from reading or being involved with it.
It could be developed further by creating more complex relationships. Maybe introduce an elf mentor for Harry who guides him in his submissive state. This mentor could have his own motives and secrets, adding more depth to the story. Also, exploring the reactions of the wider wizarding world to Harry's new role as a submissive elf could be a great addition. They might be shocked, curious, or even try to use his new position for their own gains.
For Harry, you could explore his family background more deeply. Maybe he discovers some long - lost relative on the Isle who has a different view on life, which makes Harry question his own actions and values. For Gil, he could be developed by having him learn a new skill, like fishing in a more sophisticated way, which could also give him more confidence.
