OP here again (i just went asleep long time ago, lol.)
Lucha-liches...yeah, i think i can work this out.
When someone Luchador tearing apart mask of another luchador, its first step to becoming Lucha-liche: abomination, who cannot channel themselves to the Lucha Libre, they can extract power only from reaping completely masks (or hair, if you prefer). That actions get you much more powers than extracting from mask or training but its twisting your mind and soul, and later - body. They always becoming look alike a dried p corpses, but beware - if young Lucha-liche powerful and dangerous enemy.
that was not me, really.
Loses of mask, Hair. Redemption.
Most of fights of Luchadores look more like training if when compare to the "Challenge of honor" where is bet not just mask or hair - powers and honor of fighter. When they lose, they lost most if their power, and their mask and name no more compatible with each other, and they must begin their career (with new name and mask) again, but can do it later. Winner gets all power of loser's mask, becoming stronger and perhaps with new techniques and even powers. Not honoring bet very punishing - loser who not honor their bet suffer not only from cutting their power, their lose life energy themselves, becoming Caido, another abomination of night. But there not only powers of honor, they can challenge power of their life.
