Adaptation 14, SCP 539 Acid

Item: SCP-539

Tissue Test Record: N/A

Termination Test Record: A D-class personnel (D-6384) carrying SCP-539 entered SCP-682's containment chamber and the doors were sealed behind them. SCP-682 expressed hostility towards D-6384, who threw SCP-539 prematurely in an attempt to distract SCP-682 and avoid being killed by it. Site-██ (where the test was currently being conducted) abruptly experienced a system malfunction within SCP-682’s containment chamber. This system malfunction led to an acid pump within the containment chamber to activate and entrap SCP-682, preventing it from attacking D-6384. Approximately 20 minutes after the pump's initial activation, it was deactivated by on-site maintenance staff. SCP-682 was observed with approximately 85% of its body mass destroyed, SCP-539 lying close by. No remains of D-6384 were present. SCP-682 made a full recovery approximately 3 hours later, regrowing its damaged legs and growing an additional pair of legs. The legs were approximately ██ cm higher and ██ cm thicker, with a layer of skin made from an unknown material resistant to corrosives.

Note: On-site maintenance personnel tasked with replacing the acid pump found a highly corrosive, self-multiplying substance. Analysis of the substance has revealed that it consists of several other corrosive substances, including ones of seemingly anomalous nature as well as hints of [REDACTED]. The origin of these substances is still unknown, and further research has been halted due to the lethality of the substance. - Dr. █████
