BNHA Quirk Ideas

Quirk No. 1

Name: Heal & Harden

Type: Transformation

Suggested by: Me (NV/Bxredom)

Basic Info: When the user gets injured, his wound will heal within a certain amount of time and will have hardened skin at the wounded spot for 5 Minutes. This only works if the user was injured from the "outside" of his body. So it does not work when he hits the gym too hard, for example. 
There are 7 hardening degrees, I'll sort them in their order and also the time it takes for a wound to heal (Doesn't have to damage the body, can also be triggered by the impact of a punch.)

0: Normal
1: Plastic(Takes 1 Minute to heal)
2: Wood (Takes 2 Minutes to heal)
3: Flintstone (Takes 1 Minute to heal)
4: Iron (30 seconds)
5: Diamond (20 Seconds)
6: Lego Brick (only damageable by impalement (Bullets, Cactus, Sword/Spear or similar things))
(Takes 10 seconds to heal)
7: Complete Resistance (Immune to Impalement or Damage of any kind, the whole body gets into that state, resets to Normal after 1 Minute) (Takes 3 seconds to heal)

Strengths: 
-The higher the hardening degree, the harder it is to penetrate the skin.
-Also works if he fell down the stairs and broke his leg (Just another example of usage.)
-Wounded Area becomes as hard as diamond after the 5th time. 
-Areas hit by heavy things, like a baseball bat or a piano harden aswell and can't kill the user with one hit (also works with bare hands, I just like to give stupid examples, as you should know by now lol) 
-Lethal damages are no longer possible at Degree 6 or 7 with one strike. 
-(Just another example of usage) If the user has his hand wounded multiple times and reached the iron-degree and he punches someone, the opponent will feel like as if iron has hit him. So it is easier to deal damage.

Weaknesses: 
-Easier to damage by impaling with pointy objects (e.g. above) until Hardening Degree 7
-Every wound reopens when damaged again (Depending on the previous hardening degree, how long it takes to heal the wound to shift up one degree. While it is healing again, it is back at Normal and goes back to Hardening when the wound is healed completely)
-Hardening degree resets to normal after 5 Minutes

Drawback: 
-The higher the degree went up, the thinner the skin becomes (Goes back to usual after 2 hours)
-If it reached Degree 7 just a weak bit of wind is enough to cut through the skin
-Hardening Degree 7 makes you fall asleep for 30 Minutes
-After the Degree is set back to normal from Degree 4 or above, you can rip the skin off by just pinching it with a bit to no effort
-If it was above Degree 3 and is already reset to normal, The quirk needs a resting time of one hour.
-Hardening Degree 6 leaves a huge scar behind

I might add something or edit it a bit, so feel free to look at the Info again sometimes, same goes for every over one I post.
