SCP-XXXX appears as a small Shadow the Hedgehog plushie, standing at approximately 20 cm tall. Despite its appearance, SCP-XXXX is a highly intelligent and malevolent entity capable of reality-bending and mind control. SCP-XXXX's primary ability is the power to "corrupt" items, causing them to become glitched and unusable. This corruption appears as a black, viscous liquid which emanates from SCP-XXXX and engulfs the affected item. The corruption process is rapid.
