SCP-074 Quantum Woodlouse

SCP-074 Hoodie — Observer Effect

This SCP-074 inspired hoodie is based on one of the SCP Foundation’s most intellectually dangerous anomalies: a massive organism that alters reality based on human understanding of physics. SCP-074 does not merely break the laws of nature — it rewrites them in response to observation.

Identified as a colossal isopod-like creature with wildly inconsistent physical properties, SCP-074 exhibits impossible mass, volume, and behavior. Its abilities shift depending on what nearby observers believe is physically possible. Attempts to study or define SCP-074’s properties have repeatedly caused it to develop those very traits, making research itself a trigger.

Even more unsettling, SCP-074 reproduces through quantum-scale phenomena, with offspring forming preferentially within hosts who possess advanced knowledge of physics. The more someone understands reality, the more vulnerable they become.

This design captures themes of knowledge as a threat, observation as a weapon, and science turning inward on itself.

Perfect for fans of:

• SCP Foundation lore

• Cosmic and scientific horror

• Quantum and observer-effect anomalies

• High-concept, cerebral SCPs

• Minimalist, intellectual streetwear

Product Features

• Premium heavyweight hoodie for comfort and durability

• Abstract, science-inspired artwork

• Quantum distortion and observation motifs

• Designed for SCP collectors and concept-horror fans

Why SCP-074?

SCP-074 represents the ultimate paradox: the more you understand it, the more dangerous it becomes. In its presence, ignorance isn’t weakness — it’s survival.

Don’t define it.
Don’t measure it.
And never assume you understand the rules.
