Quirk: Black blood
Quirk Type: Transformation
Quirk Class: Blood and Animal/Insect
Ability - The user's blood is black instead of red. However the user has the unique ability to turn each milliltre of their blood into spiders. The spiders don't have any venom to kill anyone but their bites will be itchy. The user can have their spiders create webs to trap areas or have them blind others. The user can turn the spiders back into blood so the user doesn't have to worry about blood loss. The user can also turn their blobs of blood into larger spiders. Even while underneath the users skin.
Combat Range: Medium
Disadvantage: -If the user's spider is destroyed they'll lose blood.
Special Moves: Spider legs- The user grows four spider legs from their back to help crawl around the city. They have two more pairs to use to attack at a distance.
My Input(Not necessary): The user has a villainous quirk. Probably out-casted because of it. The user will learn to fire their spiders like a spray and use them to spy on others. A unique quirk.
