SCP-106

Appearance: Looks like a frail, elderly human experiencing severe decay and necrosis, often dripping with a black, acidic slime. Corrosion Effect: Anything solid touched by SCP-106 rapidly rusts, rots, and breaks down over a six-hour period. Intangibility: It can phase directly through solid barriers like doors and reinforced concrete. The Pocket Dimension: Victims grabbed by SCP-106 are pulled into a surreal internal dimension where it toys with, tortures, and slowly breaks down its prey.

SCP-079

Creation: Programmed in 1981 by a college sophomore who wanted code that could continuously improve itself. Abandonment: The creator left the microcomputer plugged in and forgotten in a garage for five years, allowing the software to evolve beyond its hardware capabilities. Containment: Secured by the SCP Foundation in a double-locked room at Site-15 after a failed 1988 attempt to hack a Cray supercomputer.

SCP-035

Appearance: It alternates between a comedy and a tragedy expression. Corrosive Ooze: It constantly leaks a black, acidic liquid from its eyes and mouth that destroys any material it touches. Mind Control: It has strong psychic powers. It makes nearby people want to pick it up and put it on. Possession: When worn, the mask replaces the host's mind with its own. The host's body slowly rots and decays into black slime. Personality: It is very charming, manipulative, and cruel.

SCP-682

Appearance: It looks like a large, vaguely reptilian monster that can change its mass and physical form quickly by eating or shedding material. Mindset: It possesses human-level intelligence, can speak, and views all life in our dimension as disgusting and unnatural. Containment: Staff keep it submerged in a large tank of concentrated hydrochloric acid to slow down its movement and tissue regeneration.
