Other, SCP 23 family killer dog.

Item: SCP-023

Tissue Test Record: N/A, due to the nature of SCP-023's effects.

Termination Test Record: SCP-682 made eye contact with SCP-023 at exactly 13:48:00 GMT on Tuesday, June 18th, 2019. If this test is successful, SCP-682 will perish at roughly 13:48:00 GMT on Thursday, June 18th, 2020.

Termination Update: At 13:52 GMT, 06/18/20, a Foundation-operated extrasolar probe with anomalous FTL transmitting systems sent its hourly update of nearby stars and exoplanets. Notably, the star Epsilon Serpentis was beginning to form a supernova. Contact was then lost with the probe. Due to the young age of Epsilon Serpentis and the close time to that expected of SCP-023's effects on SCP-682, it is suspected that this supernova was the result of the test conducted one year prior.

Given Epsilon Serpentis' distance from Earth, the effects of this supernova will be observed by non-anomalous means c. 2090. When informed of the star's destruction, SCP-682 stopped speaking for several hours and has since displayed notable lethargy, though this effect is expected to diminish over the next few weeks.

Note: Due to the results of this termination attempt, no family-affecting anomalies to be tested upon SCP-682 under any circumstances.
