Appears only in corrupted footage as horizontal tracking line distortion. Manifests as a translucent humanoid silhouette overlaid with scan lines, constantly flickering between solid form and digital artifact. Emits faint phosphor glow reminiscent of CRT burn-in. Carries degraded audio remnants - tape hiss mixed with the skipped frames of recorded memories.

Serves as the ultimate witness across all 16 movie simulations - when the Chaintrix attempts to erase a player's record through membership suspension or elimination, the Ghost Signal preserves their presence as unerasable evidence. It appears in the margins of every future recording to show what was supposed to be forgotten, making elimination impossible to fully achieve.
