Goliath is an evolved G Virus that unknowningly develop inside Leon Scout Kennedy after injuries inflicted by William Birkin. Unlike other viruses, this strain occurs naturally over a span of time. It lays undetected as the genetic structure is different enough from the G Virus to avoid destruction by vaccines.

Goliath remains dormant at the beginning of its life cycle. It feeds only on viruses, parasites and germs that are detrimental to the host. This strain is symbiotic in nature as it can't survive should Leon perish.

Goliath will continue until it's large enough to enter Stage 2. This is the stage where subtle mutations will occur inside the host. Effects include slow aging, slightly boosted healing factor, minor decrease of cell death in skin, and minor increase in muscle growth.

Goliath would remain in Stage 2 indefinitely for the rest of the host's life. Unless a pretty potent virus or parasite is introduced such as Las Plagas for example. This will cause Goliath to go into Stage 3 and where the true horror takes place.

It takes approximately 4 hours for the virus to enter this stage. Signs of Goliath entering Stage 3 are: heightened aggression, increased appetite, pituitary gland doubling in size and start producing growth related hormones. Only when the virus truly reaches this stage does mutation begin.

Some potential traits of Goliath mutations depend partly on the catalyst (virus/parasite) that triggers Stage 3. Las Plagas generates aspects related to insects or reptiles such as exoskeleton w/o wings, chitin carapace, segmented/jointed limbs, scales, etc. Average traits for Goliath are similar to its progenitor such as multiple eyes and increased growth.

Unlike the G Virus, hosts fully retain their identity albeit with slight feral behavior added in. The need to reproduce is still present within Goliath but it's watered down into a mostly harmless base instinct. Infection only occurs if the host choses to do so otherwise physical contact and bodily fluids are nonviable. Although offspring of a Goliath Virus have a chance at being carriers with varied levels in dormancy.

Should a host fail to take proper care of their body then Goliath will possess them and perform the task itself. The virus has no qualms when it comes to feeding as even rotting meat is on the menu. Whether it's dead or still moving doesn't matter. Further mutation are plausible through introduction of more potent viruses/parasites.

There is a Stage 4 to the Goliath that only activates should the host be under extreme distress. How fast the transition is depends solely on the cause with near death(mortally wounded) occurring within 30 seconds and fear/rage induced stress being 20 minutes. The transformation from Stage 4 is more extreme that the host's mentality degrades to near primality.

Regression can be undone with proper mental therapy although it's heavily advised that those close to the host be present. This is to prevent potential attacks as behavior in Stage 4 is similar to a wild Grizzly Bear. (One wrong move could trigger them.) Stage 4 is a temporarily evolution which will become permanent if overused.

G!Leon stands around 10'3 in height when his virus is at Stage 3. Half his body is covered in a dark blue carapace with a thin grey layer of hide that extends 6 inches outwards from underneath and knits into his flesh. It mainly covers his entire enlarged left arm, upper torso(includes shoulder blade), lower waist(down to the kneecaps), back.

A long spindly dark blue segmented tail comes from his lower back that ends with a two prong stinger. He has a total of 8 different sized eyes across his body that range in size from 2.3 cm to 10 inches in diameter. Three can be found on his left arm, two at his left upper chest, one in the left shoulder and last two hang across the tail.

Leon's left hand has been reduced to large dexterous finger like claws that extend from a 'stump' almost if the carapace eaten his palm. While his face seems untouched, the man's jaw can disconnect and widen grotesquely similarly to a snake. Leon has razor sharp long fangs that function similar to a pen, the points can retract to mimic normal human tooth.

He tends to crave sugar and meat very often. This has led to hunting or foraging to become part of Leon's routine as how much food he needs to consume daily has tripled. He can eat normal human food although the man might dump an entire box of sugar over it if you don't have a sugary condiment.

Due to his unforeseen mutation, Leon has developed a vagabond lifestyle after RE4. He spends his days trying to find a possible cure for the Goliath virus. This has often led to Leon breaking into Umbrella or other bio-research facilities.

He is hunted by people from all sides with their own reasons. Most obviously mean harm to Leon since he's a carrier for an unknown yet powerful virus strain. Whether it's for weaponization or destruction is a mixed bag.

Although he makes it very difficult for any allies to find him either. Leon rather not put the few people he cares about in grave danger. Especially since Goliath would coerce him even harder to stay by their side for his mental health.

Saying goodbye was already difficult enough.
