I don't know for sure as I haven't read it. But likely it would include characters from Mutant X. Maybe the main characters from the Mutant X series would be involved in facing the situation with Lexa's light.
Typically in a Mutant X fanfic, we might expect to see mutants like Brennan Mulwray, Jesse Kilmartin, and Emma deLauro. But with the addition of 'Lexa's light' and a'shield against' it, there could be other original characters. It could be that Lexa is a new character introduced in this fanfic, and the story could revolve around the interactions between the regular Mutant X characters and Lexa in the context of this light and shield.
Since it's a Mutant X - related fanfic, characters like Adam Kane who is often central in the Mutant X universe could be involved. And if it's about a shield against Lexa's light, perhaps there are new characters created by the author who are related to Lexa or the light itself. However, without actually reading the fanfic, it's all speculation.
I'm not sure specifically as I haven't read this particular fanfic. But generally, it might involve the characters from Mutant X having some sort of encounter or conflict related to 'Lexa's Light' and using a shield in the context of the story's plot.
Mutant X and Lexa's fates could be intertwined in a more practical sense as well. If Mutant X is a hero - type figure, Lexa's visibility could make her a target. Mutant X might then feel responsible for protecting her. This protection could lead to Mutant X getting into all sorts of adventures and battles, which in turn would shape their fates. Also, Lexa could have information that is crucial for Mutant X's survival or for achieving their goals. Their fates are thus intertwined as they rely on each other's knowledge and abilities. And as they face different challenges together, they will grow and change, and their fates will continue to be closely linked as the fanfic unfolds.
Well, in such a fanfic scenario, one possibility is that Mutant X's new form or power could be somehow related to Lexa's visibility. Maybe the sudden appearance of Lexa triggers a reaction in Mutant X that gives them a new ability. For example, if Lexa has some sort of energy signature when she becomes visible, Mutant X could absorb that energy and transform it into a new power like enhanced strength or the ability to phase through objects. Another idea could be that Lexa's visibility is a sign of a greater threat approaching, and Mutant X turning at the same time is a pre - programmed response to this threat, sort of like an in - built alarm system.
It could be an original omega mutant character created specifically for the fanfic. This character might have abilities that are a blend of Naruto - like ninja skills and mutant - like powers.
The main characters are Adam and Emma, of course. Adam is often portrayed as a strong and intelligent leader type, while Emma has her own unique mutant powers that make her an important part of the story.
Since I haven't read it, I can't say for sure. But it's likely that the shield girl herself is a main character. There might also be a mentor figure who teaches her how to use the shield better. Maybe there's a sidekick, like a small animal or another young person, who accompanies her on her adventures.
The main character is the Shield Hero. There are also other Cardinal Heroes like the Sword Hero, Spear Hero, and Bow Hero. And there are various side characters who play important roles, such as Raphtalia, who becomes an important ally of the Shield Hero.
Harry Potter himself could be a mutant in the fanfic. He might discover he has mutant powers on top of his wizarding abilities, like the power to heal without using magic spells. This would make his character even more complex and powerful.
Well, Dumbledore would most likely be a significant character. He might be one of the few people who quickly understand the implications of Harry being a mutant. He could help Harry navigate through the challenges that come with his new identity. Additionally, there could be some mutant characters from the mutant universe who cross over into the Harry Potter world. For example, a character like Professor X could be an interesting addition, guiding Harry in understanding and using his mutant powers in a responsible way.
Since I don't know the specific fanfic, I can't say for sure. But usually in a story about a coup against corruption, there could be a leader - type character who initiates the movement. There might also be a sidekick or a group of rebels who support this leader.
