So Lyssa is the daughter to a powerful man who can control fire well she and her twin Zayden get a power/quirk close to his but Lyssa’s is more deadly then the two males combined.

So you may be wondering what’s so special about it, well whenever her blood hits an object besides Lyssa her blood would turn to blue flames for no reason and that’s why the old murderlies community house burned down, it was her when she got it, she cut her arm when she was playing with Zayden and Blaze and her blood dropped in the floor making the floor soon catch fire.

Project and Z never met a person with her powers so they had to keep an eye on her to make sure she doesn’t bleed out, Z decided to tell everyone she knew so nothing could possibly happen to Lyssa when anyone was around.

But once Lyssa fully was able to control it she knew the city they lived outside of was dangerous so asked Nexus to get her a knife that was able to hold any liquid in the handle of the knife so whenever there was threat she would press a button on the knife making the blade of the knife have her flames on it so whenever she attacked anyone with it, it could possibly burn the person or slowly and painful kill them with the horrible burn from the extreme high metal of the knife.

Oh and also if she cuts herself in a life or death situation she can throw her blood in the area where she wants it and burn that area with the flames.
