To give an example of how infused Defense Power works using the Armour gauge analogy, let's say that Alpha has 20HP and 100AP (Armour Points), where 1AP equals to 1HP.

-If he receives an attack that does, 90 damage, then Alpha will be left with 20HP+10AP and remain unscathed. If he receives an attack that deals 110 damage, then he won't instantly die even if the attack deals more damage than his maximum HP since Defense Power will absorb 100 damage, so he will only take the remaining 10. But if he takes an attack that deals more than 119 damage, it's an instant death regardless of Defense Power.

Also, Defense Power won't be depleted if the object can already withstand the force applied to it without permanent deformation.
