Like Elm, Cadaverick is a Frankenstein with a specialized Integumentary System. A rare Frankenstein in the sense that he is specialized, but not built by Dr. Richter, Harpy considered him on par with the Frankensteins of Dr. Richter. His ability manifests in the form of turning his skin into stone, and growing horns of stone to fire like bullets using his muscles. He uses this for long range and melee attacks, using it to rob and kill people.
His skin was able to negate any damage from the priests Rocket Pistol, but was useless against Ashuhito's Eisen Der Arms electrified bullets.
Cadaverick also uses a technique where he encases his entire body in a spiked boulder, to completely crush a person.
As a human, Cadaverick was a criminal with a simple lazy personality.
"Working was too much trouble, so he stole.
Stealth was too much trouble, so he robbed.
Intimidation was too much trouble, so he killed.
And then he got the death penalty."
As a Frankenstein, Harpy stated that the circumstances of his birth led to mental corruption. Despite this, little seems to have actually changed. Cadaverick kills people without care or notice, taking what he wants with no regard for them.Before he died, he begged Ashuhito for mercy, showing some cowardice.
