I'm not sure of specific examples as there could be many different 'Harry Potter is bionic fanfictions' out there. But it could be something like Dumbledore having bionic eyes that can see through all kinds of magic disguises. Or perhaps the Weasley twins create bionic prank devices that are powered by both magic and some sort of mechanical energy.
One possible example could be that the Sorting Hat has a bionic chip in it. This chip allows it to not only sort students based on their personalities and magical abilities but also on their potential for using bionic - magic combinations. For instance, it might sort a student into Gryffindor not just because of their courage but also because they have an aptitude for using bionic enhancements in a brave way, like using a bionic sword to fight dark creatures.
Since I haven't read the 'harry potter is sarcastic fanfiction', I can only speculate. But perhaps there could be a scene where Malfoy is being sarcastic towards Harry and his friends. He could say something like 'Look at the great Harry Potter and his little gang. Saving the world one clumsy spell at a time.' Or it could be that the Weasley twins use sarcasm in their pranks, like 'Dear Filch, your attempts to catch us are so adorable. It's like watching a slow - moving troll try to catch a lightning - fast wizard.'
Maybe in this fanfiction, there are in - game style challenges at Hogwarts. For instance, the Triwizard Tournament could be turned into a series of levels that Harry has to complete. Each task might have different requirements and rewards, much like in a video game.
I'm not sure specifically as there are countless fanfictions. But perhaps an example could be Harry using logic to figure out a hidden passage in Hogwarts that was previously only thought to be accessible by magic. He might analyze the architecture and come up with a non - magical way to open it.
One example could be Harry using code to enhance the security of the Gryffindor common room. He might write a code that only allows those with the correct 'password' (in a digital sense) to enter. Another example is Hermione using coding to organize all the research she does in the library more efficiently. She could create a database - like code to store and retrieve information quickly.
Some fanfictions that are overly long - winded and full of filler content can be considered the worst. They might have pages and pages of a character just thinking about nothing important or going through mundane daily activities that have no real connection to the main plot of the Harry Potter world.
One example could be a fanfic where Harry has the ability to control time without any limits, which is much more powerful than the time - turning devices in the original series. Another might be a story where Voldemort is made invincible and can defeat any opponent with a single spell, completely overpowering the other characters.
One example could be 'The Dominant Potter' where Harry discovers a new and extremely powerful form of magic early on and uses it to take charge in the fight against Voldemort. He is shown as being dominant in strategic planning and combat situations.
One example could be fanfiction that protests the lack of LGBT+ representation in the original Harry Potter series. Writers might create stories where characters are openly LGBT+, exploring their relationships and identities within the Hogwarts setting. Another could be about protesting the way house - elves were depicted. Fanfic authors may write stories where house - elves have more agency and rights, in contrast to their rather subservient portrayal in the books.
Some 'ace' Harry Potter fanfictions include time - travel scenarios. For example, a story where Harry travels back in time to meet the founders of Hogwarts. There are also fanfictions that blend the Harry Potter world with other fictional universes, like a crossover with the world of Narnia. Additionally, fanfictions that delve into the magical creatures in more depth, such as exploring the lives and cultures of the centaurs or the house - elves more thoroughly, are also great examples of the amazing and 'ace' Harry Potter fanfiction out there.
A fanfiction could have Harry Potter accidentally opening a portal to a parallel wizarding world. This regenerates the idea of the wizarding world as we know it by introducing new rules, new magical abilities, and new relationships. The author can then explore how Harry adapts to this new world and how it impacts his understanding of magic and his own identity. It's a great way for fans to expand on the original story in a creative and unexpected way.
