Immortal (Highlander)

In the Highlander franchise (films, television series, and related media), an Immortal is a human being born with the potential to live forever, ceasing to age upon experiencing their first violent death. This initial death, which triggers their immortality, is referred to as "The Quickening."

Nature of Immortality:

Immortals are biologically human, but their cellular structure possesses an inherent ability to regenerate and resist the effects of aging. They are virtually invulnerable to conventional forms of death such as disease, old age, and most injuries. However, they can be killed by decapitation, which releases their accumulated life force and energy – the Quickening.

The Quickening:

The Quickening is a surge of immense power and energy released upon the death of an Immortal, particularly when that death occurs by decapitation at the hands of another Immortal. The surviving Immortal absorbs the Quickening of the deceased, gaining their knowledge, skills, and power. This is the primary motivation behind the Game. Quickening displays often include lightning-like energy effects.

The Game:

The Immortals are compelled by an unknown force to engage in a hidden conflict known as The Game. The only rule is that there can be only one. The Game is a competition where Immortals seek out and behead one another, absorbing their Quickenings and growing in power. The ultimate goal of the Game is for one Immortal to survive and claim "The Prize," the nature of which varies depending on the specific Highlander iteration, ranging from ultimate knowledge to the power to enslave humanity.

Limitations and Weaknesses:

• Decapitation: The only way to permanently kill an Immortal is by severing their head.
• Holy Ground: Immortals cannot fight on Holy Ground (e.g., consecrated churches, temples). The rationale varies, but generally it prevents violence and death within those designated areas. Some Immortals exploit this rule strategically.
• The Source: Some iterations introduce "The Source," a mysterious power from which Immortals supposedly derive their immortality. Disrupting or controlling The Source can have detrimental effects on Immortals, possibly even ending their immortality. The Source is often considered a poorly received plot element within the fandom.
• Mental and Emotional Burden: The endless lifespan can take a toll on Immortals, leading to existential crises, grief, and a detachment from mortal concerns. They often struggle with forming lasting relationships with mortals who are inevitably shorter-lived.

The Watchers:

A secret society known as the Watchers observes the Immortals and chronicles their battles, without interfering (for the most part) in the Game. They are dedicated to recording the history of the Immortals and preserving the knowledge they accumulate.

Origin:

The origin of the Immortals is never definitively explained in the Highlander canon, leading to various interpretations and fan theories. Possible origins include ancient genetic mutations, alien intervention, and mystical forces.
