Yes, there could be. In some Harry Potter fanfictions, authors might explore the use of black magic in unique ways. A character squinting could be a sign of them concentrating on a black magic spell or perhaps they're under the influence of some dark force related to black magic. It adds an element of mystery and danger to the story.
One way to integrate it could be through time - travel. Suppose a wizard from the future where Gundam technology exists travels back to the Harry Potter era and brings with him the blueprints for the Black Magic Gundam. This causes a stir as different factions in the wizarding world either want to use it for their own gain or fear its power and want to prevent it from being built.
In some fanfictions, giant blood can amplify a character's magic. It might give them more raw power when casting spells. For instance, they could cast more powerful offensive spells compared to other wizards without giant blood. Their magic might also be more primal in nature, less refined but extremely forceful.
Often, there's the theme of temptation. The character who is squinting might be tempted by the power of black magic. It could also be a theme of corruption. As they delve deeper into black magic, shown perhaps by their squinting concentration, they start to become corrupted. Additionally, there could be a theme of mystery, with the squinting adding to the air of mystery around the black magic they are involved in.
In Harry Potter fanfiction, black magic can be used in various ways related to Harry's broken glasses. It could be that a dark spell was cast on his glasses to disrupt his vision during a crucial moment, like a Quidditch match. Maybe a Death Eater used black magic to break his glasses as a form of intimidation or to hinder his progress in finding a Horcrux.
The Black Magic Gundam could be a protector. Maybe it was created by an ancient wizard to safeguard the wizarding world from a great threat that was foreseen. In the fanfiction, it could be reactivated to fight against a new dark force that the normal spells and magic of the wizards can't handle.
