My Hero Academia+OC Black Diamond [Beta]

What are they: Artificial humans created by Dr. Kyuudai Garaki from the corpses of dead villains (and sometimes heroes) by implanting several Quirks. The corpse "resurrects," but becomes a deformed, unconscious monster. Their personality is erased, leaving only instincts and commands.

Why they were created: An army of mindless, but incredibly powerful soldiers for the League of Villains and All For One.

Classes (weak to strong):

Lower-Tier: Light skin, 1-2 quirks, dumb, only attack on command. Cannon fodder.
· Middle-Tier: Slightly stronger, more quirks, sometimes transformations (wings, chains).
· Upper-Tier: USJ-Nomu (the one who fought All Might) - black, bird-faced, regeneration + impact absorption.
Near-High-End: Almost like the elite, but without the brains. Can be mass-produced.
High-End (Elite): The strongest. Up to 6+ Quirks, retain their personality, can speak, and analyze their opponents in battle. Hood—the one who fought Endvor—has 6 Quirks and could release lower-level Nomu from his body.

Key Nomu:

USJ-Nomu: First seen. Regeneration + Shock Absorption. Created specifically to counter All Might. Later revealed to be a former small-time gangster.
Kurogiri: The first Nomu. Created from the corpse of Oboro Shirakumo (Aizawa and Mika's friend). Retains his personality and ability to speak, but his memory is erased. His instinct is to protect Shigaraki.

first name: Mizuki last name: Bort
Appearance
Age: 16–17 years.
Hair: Black with a blue-violet metallic sheen, straight, perfectly even, waist-length. When activated, it becomes diamond-like; the length and shape don't change—it simply transforms into a black industrial diamond.
Eyes: dark grey, almost black, cold.
Skin: pale, with a bluish tint.
Clothing: white polo shirt, black skinny tie, black suspenders, short black shorts. Long black gloves, black knee-length stockings, pumps.
Character
Cold, taciturn, and aloof. She speaks quietly, dryly, and to the point. She rarely smiles, often looking at me with arrogance and an appraising calm. She's not aggressive, but rather apathetic. She enjoys reading and prefers silence.
The reaction to insults is silent but quick. It doesn't explode, it just remembers.
Quirk: Carbonado (Black Technical Diamond)
Type: Mutation/Isolation
Bort's hair has been composed of black industrial diamond since birth. It cannot be burned, dissolved by acid, or cut by metal. It also retains the flexibility and movement of normal hair until she activates its control.
In combat mode, she can manipulate her hair:
Shaping: Instantly compresses strands into rigid blades, shields, spikes or flexible saw-whips.
Barrage: Fires individual hairs like diamond needles up to 20 meters away.
Propelling: Uses hair as extra limbs to grab, move and propel itself.
Weaknesses
Cleavage (brittleness): When struck with a strong crushing force at the correct angle, the diamond structure splits along the crystalline planes. The hair crumbles and loses its hardness until it recovers.
After exiting combat mode, the sudden change in stress on her cervical spine and vestibular system causes dizziness, impaired coordination, and possible nausea. It takes several minutes to recover.
Diamonds burn in intense heat. Direct exposure to flame can destroy some hair.
In normal condition they are soft, in combat condition they are hard.
