-I'd like to thank LL/Hawkshade for always being cool about letting me play off of her concepts to create off-shoots like this-

The Blackdagger of Grimm

There were legends among the Strigidae. Whispers of men and women who'd turn their backs on the death cult and went rogue on the Seven Secret Masters - yet still served them. Served them as assassins whose minds and bodies were held captive by the darkest of Strigidaesciences and the foulest of Arcani sorcery. They'd abandoned the Strigidae Order, and were made to pay. The traitors. The maggots. The scum. Forced into a life of secret servitude for their treachery. They were the Blackdagger. The unseen blade of the Strigidae. Until now.

The Unseen Blade - Origin/Background

In the icy peaks of the Alps, lay a stronghold of maniacs and extremists. A home to the most radical Strigidae. Nest 629. And it was where the Blackdagger - their humanity corrupted and mangled - spent their days. And there, they were shackled to the will of a dead man; Boresight. A tireless monster slain by the Son of the Shogun and raised from the dead by powers never meant for the hand of man, he was given the secret words that bent the Blackdagger to his will. There, in Nest 629, Boresight was their judge and their master. By night, the Blackdagger moved in the shadows, spilling the blood of Strigidae enemies and hunting down those who'd severed their ties with the Strigidae death cult. But by day, they learned obedience. Some of the world's great killers traded their weapons for broomsticks - and swept the courtyard.

It was their life. And it was to be their life. But the Strigidae had abandoned Nest 629, left them to spend the rest of their days under Boresight's watchful eye. Yet there came a day. When the Orochi climbed the mountains like a rising mist. Led by Grimmwald, they stormed the Nest, and Boresight stepped forth in neither fear nor surrender. He fought. Tirelessly. Tenaciously. Fearlessly. But for naught. His defeat was certain and sealed as he was skinned alive and his flayed skin given to the Horned Saint as a trophy - and warning to his enemies. The Blackdagger, were now Grimmwald's.

The Rogues - Members/Organization

Their blood oaths abandoned. And their minds bound to the hand of cruel sciences burrowed deep in their brains, the Blackdagger have no autonomy over themselves. They are forever held hostage by the control words passed down from the Seven Secret Masters to Boresight, and now Grimmwald. Stripped of their names and known only by codenames (Famine, War, Pestilence and Fury) they are as follows:

Famine

Real Name: Unknown, Height: 6'9", Weight: 496 lbs

A bestial mutant, Famine is the largest member of the Blackdagger. A savage killer with an eye for ambush, Famine's primary mutant power is the manipulation of biomass, which he consumes from the organic matter of other living things, specifically by cannibalizing other mutants and humans and converting them into biomass. This consumption process sustains and accelerates Famine's regeneration, enabling him to recover from injuries quicker when he is absorbing biomass. The more biomass Famine absorbs, the stronger, faster and more durable he becomes. In addition to simply growing in power from his consumption of biomass, Famine also gains the knowledge, skills and memories of those he cannibalizes, a condition that has seen him grow into a deadly warrior and further expand upon his power over biomass.

The chief reward from this condition is the versatility with which Famine can manipulate biomass. Specifically, he incorporates a form of limited shapeshifting to fashion parts of his body into weapons. He often hardens and sharpens the biomass around his hands and shapes them into large blades or talon-like appendages that can cut and shred through most materials. Or he may fashion extend-able tendrils with bladed edges or enormous hammer-like constructs by routing large amounts of biomass towards his hands. Because his power revolves around cannibalizing other mutants and humans, Famine's teeth are long and extremely sharp and designed to shred through both flesh and bone. His tongue also acts as a deadly appendage, able to stretch long distances and wrap round Famine's victims with great strength. Furthermore, Famine does not have a fixed jaw and instead has ligaments that allow his mouth to expand large enough for him to swallow human-sized victims whole.

War

Real Name: Unknown, Height: 6'3", Weight: 784 lbs

Reserved and stern, War is a mutant born with a body made from an exotic organic metal. While three quarters of the human body is water, War's cellular structure is significantly different. His metallic cells host a tight weave of atoms that render his body far denser than a human's. And because of the higher density and enhanced quality of his cellular structure, War's cells are able to collect and store electrical energy. He is naturally superhumanly strong and durable, able to lift in the realm of 5 tons while his metallic skin is nearly impenetrable, protecting him from penetration by bullets, blades etc. However, while his external durability is remarkable, War is far more susceptible to internal injuries from blunt force trauma, explosions etc. despite his cellular density.

War often uses the stored electrical energy in his cells to replenish his stamina, however, in the event that his strength is not enough to overcome a physical barrier, he harnesses his stored electrical energy to generate a powerful alternating current that resonates through his body at very high frequencies. This alternating current allows him to weaken the molecular bonds of anything he touches, allowing him to bend materials too rigid for his strength, and break through barriers his punches would otherwise fail to dent. This ability however, is extremely taxing and depletes him of his stamina. Because of his great density, War's speed is of an average human's.

Pestilence (Defeated)

Real Name: Unknown, Height: 6'11", Weight: 194 lbs

One of the stranger members of the Blackdagger, Pestilence is a diseased mutant. A mute with a permanent and maddening grin, he is incredibly thin yet the tallest member of the group. Born with sharp needle-like teeth and long dagger-like claws, all of which can cut through flesh and bone, Pestilence's powers are peculiar and they are rumored to be owed as much to the cruel experiments of the Strigidae as much as his own mutant genes. Though he is neither superhumanly strong nor durable, Pestilence's body has been twisted close to the peak of human physicality. His greatest powers however, lie elsewhere. There is a perversion in his veins. A physical corruption he transmits to others through his claws and teeth, and the bladed chains painfully bound to his flesh.

By cutting, biting or lacerating his foes, Pestilence can infect his foes with an excruciating sickness that causes the bones to push out against one's skin until flesh breaks, the eyes into black sacs filled with rotting pus, and a wasting disease that consumes the victim layer by layer. Those with powerful immune systems however, can resist these effects. Still, Pestilence is dangerous. The chains bound to his flesh can stretch to a length of 20 feet, and are wielded by him with deceptive expertise. Additionally, their bladed edges can cut through most materials. Perhaps most disturbing is Pestilence's jaw strength. While he is not superhumanly strong, his jaw appears to be as he is able to crush bone and even chew through steel with a bite, while his small leeches in his mouth latch onto the flesh of those he bites and suck out their bodily fluids until they're nothing but dried and dying husks.

Fury

Real Name: Unknown, Height: 5'9", Weight: 164 lbs

Fury is a warrior, and her genes stem from a long line of formidable mutant warriors. With a genetic structure that is home to decoded genes related to a warrior's performance in her bodily systems, she is not only naturally equipped for battle but she is highly resistant to disease and toxins and though she lacks an accelerated healing factor, her endurance - her ability to fight with sustained injuries, in other words - is remarkable. Fury's primary power however, is owed to her muscle fibers. While the ordinary human body contains slow-twitch red muscle fibers and fast-twitch white muscle fibers, Fury's body contains a unique combination of both; pink muscle fibers. Her pink muscle fibers combine the larger number of mitochondria, superior local capillary density and higher ATP of slow-twitch muscle fibers with the glycolytic enzymes and power of fast-twitch muscle fibers.

Fury, therefore, is a perfect blend of freak endurance, stamina, explosiveness, strength, and speed. Beyond her superhuman athleticism, Fury's bones are much stronger and harder than ordinary human bones given their larger percentage of calcium, magnesium, phosphorus, Vitamin D and other minerals. Furthermore, her body is also home to a secondary nervous system that uses an unknown neuroconductive fluid. In the event that her primary nervous system is damaged or disabled, her secondary one takes over. Finally, while Pestilence is armed with chains, Fury is armed with gloves and boots that contain retractable vibranium blades, with her boots holding one blade each at the tip, and her gloves holding two blades each on the knuckle areas.
