Capabilities

The user can manipulate the process of decomposition, commanding the breakdown of organic and inorganic matter with unparalleled precision. They can accelerate or slow the rate at which things rot, decay, and disintegrate, bending the natural order to their will. This power extends to both the living and the non-living, enabling them to cause plants to wither in moments, rust metal into powder, or disintegrate solid stone with a mere touch. Their control is not limited to destruction; they can halt or even reverse the effects of decay, restoring broken-down or deteriorated objects to a prior, more intact state. With this ability, they can preserve a dying plant, prevent a structure from crumbling, or even heal the damage of time itself.

The user’s mastery also grants selective decomposition, allowing them to target specific materials, objects, or living tissues while leaving everything else untouched. They could rot the armor off an enemy without harming their body, weaken the foundations of a structure without disturbing the walls above, or cause a poison within the bloodstream to decay without damaging the host. This refined control makes their power both precise and devastating, capable of dismantling complex systems or striking surgically at hidden weaknesses.

Beyond controlling the rate of decay, the user can manipulate the agents of decomposition — the life forms that thrive within the process of rot. Vermin, maggots, worms, and insects that feed on decay can be summoned, controlled, or dispersed at will, acting as living extensions of the user’s power. These creatures can be commanded to break down specific targets, swarm opponents, or dismantle objects in a matter of moments. The user can even manipulate the natural processes within living organisms, causing wounds to fester, preventing them from healing, or alternatively inducing rapid regeneration by halting decay within living tissue.

This ability extends beyond simple control of rot — allowing the user to twist the very nature of decomposition itself to suit their needs. They can cause the rapid collapse of fortified structures, while simultaneously preserving their own body against the effects of time, maintaining their vitality for as long as they desire. They could summon armies of decay-driven creatures to aid them in battle, or erase the effects of ruin from barren lands, restoring life where death once ruled. At the peak of their mastery, the user transcends even physical manipulation, gaining influence over the concept of decomposition. They can reshape natural cycles according to their will, creating sanctuaries where nothing can decay, or casting curses over entire regions where all things, living or not, steadily waste away. With a mere thought, they can dictate whether decay brings ruin or rebirth, using it as a weapon, a shield, or a force of restoration.

The power also grants profound sensory abilities: the user can "read" the stages of decay in their surroundings, sensing the age, weakness, and hidden faults of any material or being, pinpointing vulnerabilities invisible to the naked eye. They can erode weapons mid-swing, crumble defenses with a glance, or render entire battlefields inhospitable by saturating the air with the heavy presence of rot.

In the hands of a master, Decomposition Manipulation becomes more than a power of death and destruction — it becomes the force of renewal and transformation. For what decays can nourish new life, and what is broken down can be reshaped into something stronger. The user commands both the end of all things and the beginning of what comes after.

Tatsuya Shiba's (The Irregular at Magic High School) decomposition magic is so great that he can even replicate the effects of a nuclear bomb at will.

Mukuro Hoshimiya (Date A Live) can use her Angel <Michael> to use Jerez a technique that decomposes Reiryoku and the bonds holding molecules together as seen when it completely annihilates Tenka's Astral Dress.

Mukae Emukae (Medaka Box) Minus allows her to corrode and dissolve anything she touches. Though her power only works through her hands, it is powerful enough to corrode anything from concrete to the air around her.

Pollux and Cartor (God of War) can cause things to decay, even stones.

Kid Rot (Grossology) can manipulate rot-inducing bacteria to dangerous proportions, even being capable of projecting rotting energy blasts.
