There is no question about it. There is no creature more fearsome, hungry, and murderous than the clockwork. These beings of flesh and metal are highly infectious and notoriously hard to kill. Only flames can match the hunger of the clockwork. The element that many feared for its destructive power is now their only savior. Below is a list of strains of clockworks that exist. A list that is unfortunately growing.
One of the most well known and feared clockworks, harpies are known for their disgusting killing methods, their massive jaws, saggy flesh, beautiful wings, and their nasty attitude. They perch high up and seek out any movement. Harpies are movement based predators, meaning that if a person doesn't move when a harpy is looking for a victim, they will not typically attack. Not moving will not work after the clockwork has already locked on and as such this defense method should only be used if the person can confirm the harpy is not already attempting an attack.
Typically dormant until activity dies down for the day, sirens are known to lurk dark alleyways, abandoned buildings, and deserted streets. While mostly an urban clockwork, they can be spotted in rural and in the middle of absolutely nowhere in sporadic cases.
The siren call is what sirens do about every 5 to 20 minutes while seeking prey. They yell into the air a phrase such as "Help me!", "Hello?", "Come here!", "AAAAHHHHHH!!!", or a plethora of other common phrases to get the attention of any onlookers.
Should a chimera be well fed, there will be no ill effects. It will remain in an inactive and noninfectious state, and apart from the original infected body part, there will be no more physical effects. To satisfy a chimera, it must be fed a meat product every time the host eats, regardless if it needs to feed or not. The host will have to stick to a strict diet and carry small meat bits to feed their chimera should they decide to snack.
The cetus strain is docile compared to other clockworks, but do not be fooled, this strain is just as deadly as many others. Instead of actively hunting its prey the cetus has over productive glands that ooze out far more of the infectious, yet flammable slime that is a crucial trait in clockworks. When a cetus exits a water source to locate a better one, this slime makes them highly vulnerable to all fire-based attacks. A single lit match would set the cetus, and the path it slithered ablaze and is the recommended way to dispose of them. The cetus can afford this major weakness due to its habitat.
Dryads are skittish clockworks and avoid most organic creatures, a trait rare to see in the typically all-consuming clockwork. When small they latch on to a safe spot, attempting to blend in and only moving when trouble arises. If anything kills them all land they have infected will continue to grow but at a slower pace until another dryad is created. This can take months to years to happen. Typically authorities will spot the infected land and burn it before another dryad can be made.
