Film: X-The Unknown (1956)
Location: Underground/Civilized area
Height/Weight: Fluctuates, though probably pretty heavy.
Summary: It has waited eons for this moment. This moment of freedom. This moment of power. This moment of muddy madness. Prepare for radioactive burning, people, because X is back in town!
History: Near the beginning of time, when the world was near-unstable, beings of pure energy and matter thrived. But with the changing elements, almost all of them were sent back into the Earth's crust. Every 50 years, they would attempt to break out of their subterranean prison to no avail. However, with the modern increase in radiation, one energy monster dubbed X has finally crossed over through a rather large fissure.
Notable Kills: All that radiation royally screwed up its every victim's face.
Final Fate: X is ambushed by radio towers placed on each side of the fissure. This causes it to over-function and eventually explode into flames.
Powers/Abilities: X is nigh-invulnerable due to lacking any internal organs, grows with all the food/energy it gets, and being filled to the brim with deadly radiation.
Weakness: If X takes in too much radiation and/or energy at once, it will explode.
Scariness Factor: 5-True terror is often something that has no form, and X proves this to a T. Deadly to even stand next to, this amorphous mass can't even be killed without hurting others.
Trivia: -This film was originally going to be part of the Quatermass series, but copyright issues prevented this.
-This film's original director, Joseph Losey, made it in the UK due to being ousted by Hollywood for accusations of being a communist. Due to illness, his role was passed to Leslie Norman.
