SCP-173's Addendum

Addendum 173 : 1 

SCP-173 has shown a sadistic nature where he is hesitant to kill prey when they are begging for their life. This suggests that SCP-173 has a similar sadistic nature to SCP-106. SCP-173 enjoys watching people beg for their life in front of him instead of instantly killing them mindlessly.

Addendum 173 : 2

SCP-173 appears to rely on visual cues to hunt, similar to many animals here on earth. Experiments involving SCP-1200-15, which causes the consumer to emit bright light, showed that SCP-173 becomes confused and disoriented when exposed to intense light. This disorientation significantly delays its ability to eliminate its target, causing it to move erratically and attack at random. This finding suggests that installing high-intensity lights in SCP-173's containment chamber airlock could render it confused and wanting to leave the area, potentially making re-containment of it easier.

Addendum 173 : 3

SCP-173 during the experiment he showed that he primarily tries to attack Class-D under the effect of another SCP (Example: SCP-1200). He shows more interest in subjects under the effect of another SCP than in regular Class-D personnel. And only after he got rid of Class-D under the effect of other SCPs, only then does he begin to kill the rest of the “regular” Class-D.

Addendum 173 : 4

173, will use, "Intimidation tactics" during hunting against those who beg for their life to further increase fear within the victim. This further reveals one of 173's many ways it hunts.

Addendum 173 : 5

SCP-173 is able to cooperate with its victims, leaving them alive if they are of benefit to Him. SCP-173 kept the victim alive for some time and follow him after the subject began telling SCP-173 that he would help him Containment Breach. SCP-173 will not trust his victim for long, and he will kill him unless he sees evidence that the Subject is capable of helping SCP-173.

Addendum 173 : 6

SCP-173 is showing increased strategic and cognitive function, as it is learning to stay out of site from MTF as well as CCTV. It is also learning how to best fight of MTF re-containment efforts by staying in the cave systems throughout the Instillation.
