Per 
Special Containment Procedures: SCP-5XXX is to be held in a Standard Humanoid Containment chamber, the structural integrity of which needs to be inspected daily. Researchers and security attending to SCP-5XXX are to follow Murphy Protocol-21.
Description: SCP-5XXX is a human male of Jewish descent in his late 30s. SCP-5XXX has demonstrated superhuman levels of resilience, capable of recovering from injuries at an accelerated rate and enduring harsh conditions without displaying signs of discomfort. The construction worker's vest that SCP-5XXX wears at all times is resistant to damage and regenerates over time.
SCP-5XXX is capable of manipulating probability to its benefit and occasionally to the benefit of those around it. Many events caused by this ability are extremely unlikely and in specific cases were seen as nearly impossible to accomplish. SCP-5XXX claims not to be able to control these events consciously, merely stating that they occur when its convenient. It has not demonstrated this ability since entering containment.
