Ubistvo

Ubistvo (which means "Murder" in Serbian) is one of the more unique evolutions (sometimes referred to as Complete Mutations) that can occur from a C-Virus infected person emerges from their Chrysalis. A typical infected such as a J'avo will usually enter a Chrysalid state once they have sustained a lot of damage, but sometimes an infected person can enter a Chrysalis almost instantly, possibly depending on will or emotional state. In this particular mutation the creature which emerges is an extraordinary dangerous and powerful monster; so much so that their developers have tried to restrict their usage as much as possible.

The mutation is quite extreme; although the form is still fairly human in shape, all of the internal organs have been shifted around their skin has transformed into a strange muscle material, along with a brighter outer layer which only covers approximately half of their body. Some parts of their limbs also have growths which may serve as aerodynamic aids and armour plating. However the most incredible aspect of their mutation is their chainsaw, which operates like a typical petrol-powered one but is entirely organic and part of their body.

It has two main distinctive abilities - the first being their organic chainsaw-like appendage made of bone and strong connective tissue. The second being their resilience - they will attack their target and absolutely will not stop until it is impossible to continue. While it may look like they have been defeated in a firefight, it will soon resume it's pursuit and this can happen many times. One particular Ubistvo has been observed shaking off normally fatal injuries such as electrocution and massive trauma. This particular variant was finally defeated after being sliced apart.

Interestingly, in earlier concepts of the Ubistvo, they carried a normal chainsaw. However this made them rather similar to the Chainsaw Man (Dr. Salvador) from Resident Evil 4.
