Bio: Cobweb is a demon from the Mindscape, the same dimension that Sleepwalker originates from. The Mindscape is a world not found within the regular universe, yet it borders on the minds of all intelligent beings in the universe.
Cobweb stalks the Mindscape preying on innocent and defenseless minds, twisting and tearing at the thoughts within until the victims cannot tell truth from lies. This ulitmately plunges Cobweb's victims into madness.
It was actually due to the actions of Cobweb that Sleepwalker found himself trapped inside the mind of Rick Sheridan. Cobweb tricked Sleepwalker into entering Rick's mind, where the two fought in his dreams. When Cobweb left, Sleepwalker found himself trapped, only able to escape from Rick's mind while he was sleeping.
It was later revealed that Sleepwalker's race from the Mindscape was not one dedicated to protecting Earth but in fact secretly planned to conquer it. When the race tried to invade the world, Sleepwalker decided to rebel. This turned out to be a plot by Cobweb to spread mass insanity and thereby gain more power. Cobweb transformed his own minions to appear as the Sleepwalker race and sent them to Earth using Sleepwalker's long lost Imaginator. After reclaiming the Imaginator, Sleepwalker disappered into the subconcious of his host, Rick.
