Hermione Granger would be a great character to pair with Tifa. Hermione's intelligence and knowledge of magic could complement Tifa's combat skills. They could work together to solve mysteries in the wizarding world, like finding hidden magical artifacts or uncovering the secrets of an ancient spell.
The character of Lockhart himself. He's so full of bluster and false bravado in the original books. Fanfic can explore what's really beneath all that. It can show his true motives, his hidden strengths or weaknesses.
There might be a fanfiction where Lockhart gets a chance at redemption. After his memory charm fiasco in the original books, in this fanfic he could be trying to make up for it by helping Harry out in a dangerous situation. Maybe he uses his knowledge of the wizarding world's more obscure corners to save Harry from a dark wizard's trap.
In many Harry Potter fanfictions about Gilderoy Lockhart and with a 'lemon' aspect, he could be seen as trying to steal the spotlight even in romantic or more adult - themed situations. Since he's so full of himself in the original books, fanfic authors might play on that. For example, he might be using his false tales of heroism to impress a love interest in a rather over - the - top and humorous way, while at the same time, the 'lemon' elements add a different layer to the story.
One interesting Harry Potter Lockhart fanfiction could be one where Lockhart actually has a change of heart and uses his charm for real good instead of just self - promotion. He might start teaching real defensive magic and help the students in a more sincere way.
There is no truth to it at all. The 'Harry Potter' world created by Rowling is mainly about magic, friendship, and the fight against evil. Fanfiction sometimes goes off on wild tangents, but this is an extremely inappropriate and baseless idea. Lockhart in the official story is a self - absorbed but not a sexually abusive character, and these fanfiction ideas are a distortion of the original concept.
One interesting fanfiction could be where Tifa Lockhart somehow gets transported into the Harry Potter universe. Maybe she uses her combat skills to help the students at Hogwarts in a time of great danger, like when the Death Eaters are attacking. She could teach them some unique fighting techniques that are different from magic.
There's also 'Lockhart's Lost Lessons'. This fanfic imagines what would have happened if Lockhart had actually been a competent teacher and had real magical knowledge to pass on. It's an interesting take on his character and how he could have influenced the students at Hogwarts.
It might be a magical creature that has been corrupted by dark magic. For example, a hippogriff that has been turned evil. It attacks Harry when he's out exploring. Lockhart, who has some knowledge of magical creatures, tries to calm it down at first but when that fails, he has to use more forceful magic to save Harry from the enraged hippogriff.
