Euclid Class SCP

Euclid is one of the three Object Classes used by the SCP Foundation to categorize anomalous objects and entities based on their properties and level of containment difficulty. SCPs that are classified as Euclid are unpredictable, difficult to contain, or exhibit active aggression towards Foundation staff.

Euclid SCPs require more resources and planning to contain and are considered to be a moderate threat to human life and/or normalcy. These SCPs may have the potential to cause significant harm or disruption if they are not contained properly, but they are not as inherently dangerous as Keter-class SCPs.

Euclid-class SCPs are generally subject to regular observation and experimentation to better understand their abilities and behavior. They may also require specialized containment procedures and/or equipment to mitigate their effects or prevent their escape.

Some examples of Euclid-class SCPs include SCP-096, a humanoid entity that becomes violent when someone views its face, SCP-049, a humanoid entity that can animate and control dead bodies. And SCP-082 is a humanoid creature with immense strength and durability, capable of regenerating from most forms of physical harm. 

Overall, Euclid-class SCPs represent a significant challenge to the Foundation and require a high level of caution and preparation in their containment and study.
