As you may know, every living being in the world has unbreakable bones, animals, insects specifically their exoskeleton as they have no bones, and finally, humans.
Although there are a few exceptions, they are called 'breakers'. Some living beings have the ability to break one or more of their bones in exchange for power. Naturally, the more important the bone is to the body, the more powerful their breaker ability is.
There are 2 ways of making a breaker ability more powerful:
1-Experience on how one can utilize their breaker ability.
2- repeatedly breaking the bone, once the bone heals, it grows slightly stronger but becomes slightly harder to break as well.
Breakers are able to heal their bones in 30 minutes and they can only use their abilities when their bone is broken. So naturally the more you break it, the more time you can use the ability, this rule is universal to all bones.
Abilities given for each recorded bone (Human):
Finger: Once breaking a finger, you gain the ability to shoot bullets out of them. The bullets become bigger and more concentrated the more you break it. (One finger is counted as one bone.)
Knuckles: Sharp spikes come out of the knuckle, the spike becomes more refined the more you break it. (Again, one knuckle is considered as one bone.)
Arm: A shield comes out of the arm, this shield starts off as somewhat durable, being able to withstand a truck traveling at 50kmh. The shield becomes bigger in size and more durable the more you break it.
Elbow: The arm becomes a whip. The range gets extended the more you break it.
Shoulder: The arm becomes a spring, it's similar to the elbow however like a spring, it can compress and launch out, naturally the launch is stronger the more compressed it is. It becomes faster to compress the more you break it.
Spine: One of the more powerful breaker ability due to it's function in the body, it can essentially allow one to temporarily act out their desired path without fail. However, after the bone heals and the ability is gone, you are momentarily paralyzed, unable to move for 30 minutes. The more you break it, decrease the time of paralysis by 1 second.
Skull: Another powerful breaker ability, once the skull is even fractured, a mask engulfs the user's head, which gives them increased reflexes, and slow down their perception of time by 25% allowing the user to plan out their next action. The more you fracture it, the slower your perception of time is, by 0.01%. However if the skull is broken and not fractured, the perception of time becomes 50% slower however due to the damage, the user will be in a berserk state. (MUST BE ELIMINATED AT ONCE OR STALLED UNTIL THE SKULL HEALS)
Jaws: One of the newer bones to have been recorded, the ability is quite simple, the user's mouth becomes even larger and they have the ability to eat anything as long as it fits their mouth. The mouth becomes larger the more the user breaks it.
Knees: Instead of the arm, the leg becomes a whip. Range gets extended the more you break it.
Legs: A large blade manifests out of the leg. The blade becomes sharper and larger the more the user breaks it.
Foot: Boosters manifest on the back of the foot, allowing the user to move faster by using their blood as fuel. The more you break it, the faster you can move and the less fuel you need to use. It is recommended that you break your foot 10 times before using the ability to reduce the blood loss.
Toes: Your movements become completely silent as long as you're on your toes. Your presence is practically invisible. That is, if all 10 toes can break. The power gets weaker the less toes there are to break. This is a special bone, as it doesn't have a unique increase in power compared to other bones.
Palm: A metallic bone covers the palm, if something comes into contact with the palm, a piercing sound is conducted. If both palms can break, the user can clap and it will make a sound so loud it creates a shockwave which can cut solid objects slightly. The more the user breaks it, the louder the sound created by the palm is.
Hips: The hips can spin 360. If the user breaks their hips, the faster the rotations can be, if one breaks their hips a certain amount of time, they can essentially fly.
Those are all of the recorded bones by us, the Official breaker association, AKA, OBA.
Factions of the breaker society:
OBA: We prioritize on protecting civilians from the other factions who harm them.
Rogue breakersociety (RBS): The RBS are rogue breakers who have abilities not known by the OBA, they work in secret, and they cause chaos for the fun of it.
Monster breakers (MOB): A MOB is an animal or insect with a breaker ability. Although due to the fact some of them have different bones, some MOB abilities aren't known. Also due to the fact that they rely on their instincts more, a MOB tends to be extremely violent and must be eliminated on the spot.
Non-breaker society (NBS): The NBS are the civilians in this case. They don't really do anything.
Breakers' in learning (BIL): Student breakers that have yet to join a faction and still are in the breaker academy.
Additional information:
If a non-breaker's bone breaks due to some unknown conditions, they gain the ability at it's strongest form however it is forever stuck that way and there is no known way of making the bone return back to its' fixed state. This only occurred twice in history, the first one being 25 years ago and the second being only a year ago.
That is all, good luck on becoming a breaker. We wish you the best of luck. -William Breaker, from the OBA.
