Endurance is the ability of an organism to exert itself and remain active for a long period of time, as well as its ability to resist, withstand, recover from, and have immunity to trauma, wounds, or fatigue.
In other words, Endurance defines how tough your character is. Higher Endurance means a tougher, fitter character. Lower means a weaker, out of shape character. Individuals with high Endurance can survive in hazardous and dangerous areas such as Ground Zero and the Kanto Desert without aid (+19-20.) The Strength of a character tells what kind of damage they will do against another character. Obviously, if a character's Strength is lower than their opponent's Endurance, they will do little to no damage (Except in the case of guns and specialized weapons.) If a character's Strength is even to or close to their opponent's Endurance, the damage they will do is normal. If a character's Strength is above their opponent's Endurance, they will do high/massive/catastrophic damage to the opponent.
Endurance Table
+0: Below Normal: Weak and sickly
+1-3: Normal: Average resilience to injury and/or disease
+4-6: Athlete: Conditioned metabolism enabling highly efficient healing
+7-9: Peak Human: Conditioned metabolism enabling extraordinary efficient healing
+10-12: Enhanced Species: Skin, bone, and muscles are augmented to levels that are somewhat harder and stronger than human. Impervious to injury to a certain extent
+13-15: Enhanced Species II: Skin, bone, and muscles retain their human durability but the body is able to heal injuries that would prove lethal to ordinary humans by regenerating cells to a limited extent
+16-18: Superhuman: Skin, bone, and muscle tissues are augmented to levels that are considerably stronger and harder than human and the tissues are impervious to injury to an extraordinary extent
+19-20: Metahuman: Able to withstand extreme temperatures and pressures. Able to withstand virtually all toxins, corrosives, punctures, and concussions without sustaining injury
+21-23: Demi-Godlike: Able to withstand all injury short of a direct nuclear explosion
+24: Godlike: Able to physically withstand almost any force without injury and/or reconstitute the body after having most or all of the bodily tissue destroyed
+25: Indestructible: Cannot be Injured (Admin Permission Only.)
Things to Remember:
Any and everyone can only take so much before they get hurt. Let's be realistic here. If someone significantly stronger and faster than you lands a hit, 9 times out of 10 you're going down.
Healing abilities are allowed; however, they will not have you back 100% as soon as it is used. Again, let's be realistic here. Healing will take time, meaning several posts.
No one is immune to or can regenerate from decapitation (except for those with the ability Totipotency, currently limited to only Darkman, or the ability Adaptive Resurrection, which prevents it's user from dying the same way twice, currently limited to only Demi.) Having your head cut off of your shoulders = you're dead.
