The Entity

The Entity
The Entity is a malevolent force of mysterious origins that follows its victims, regardless of their location or distance, and attempts to brutally kill them (often in a pseudo-sexual manner) upon making contact. Similar to a Sexually Transmitted Disease (STD) The Entity is summoned to a new victim when that person engages in sexual intercourse with someone who is currently The Entity's prey. The monster will only follow one person at a time, though it will attack any individual who gets in the way of it's pursuit of the victim.

The Entity is invisible to anyone who hasn't contracted its sexually transmitted curse, but will remains visible to those who have been exposed to the curse, even if they are not currently its prey.

Once The Entity successfully murders its victim, it will continue to pursue the last person who was able to avoid it by spreading the curse, which means the best way to avoid its pursuit is to spread the curse further by having sex with a new victims and informing them to do so as well, thereby further separating yourself from its pursuit. But as long as The Entity is successful in killing its prey, it will eventually come back for you. No matter how far you run, The Entity will always be moving on its way to the current victim, never stopping to rest. A cursed person can buy themselves time by moving far away from The Entity, but it was always be somewhere in the world, slowly moving closer.

The Entity moves slowly, usually at a walking pace and can take the form of any person, including the friends and love once of its victim, giving it the ability to trick the victim into letting it get close to them. Its forms seem to vary, sometimes randomly, between normal looking people and bizarre or gruesome representations of humanity.

Analysis
Though it does exist in its universe as a tangible force with a subset of rules, like many movie monsters, The Entity is often thought to exists as an allegorical representation of sociological issues in our culture. In this case, these topics have been said to include sexual violence, STD's, surviving assault, loss of innocence and the inevitability of our own mortality, among others.
