Core Traits and Powers:
1. Enhanced Physical Power
Multiplies the user's strength, speed, endurance, and aggression.
Allows Guts to fight beyond human limits—even when critically injured.
2. Pain Suppression
The armor suppresses pain and fear, allowing the user to fight with broken bones, torn muscles, or impalements without hesitation.
The armor literally moves broken limbs back into place with spikes or force, turning the user into a walking corpse that refuses to die.
3. Battle Trance / Bloodlust Mode
The armor unleashes Guts' deepest rage, putting him in an uncontrollable, almost animalistic state.
He becomes a mindless beast—tearing through enemies without regard for friend or foe.
In One Piece: this could be like a corrupted form of Haoshoku Haki—his presence exudes overwhelming bloodlust, terrifying enemies into paralysis.
4. Corruption of the Mind and Soul
The longer Guts uses it, the more the Beast of Darkness (his inner violent psyche) takes over.
It's not just a tool—it feeds on his trauma and bloodlust.
He risks losing himself entirely, becoming no different than an Apostle or monster.
5. Toll on the Body
Despite numbing pain, the body still suffers damage. Guts is often near death after every major fight.
The armor accelerates wear on his muscles, bones, and organs. It's killing him slowly.
Design Features
Jagged, wolf-skull-like helmet with glowing red eyes.
Spiky, brutal frame that looks more demonic than knightly.
When active, it reshapes around Guts, making him look inhuman.
