The Hole

Origin
While William Holt was under Ookook's influence, he was forced to break a hole in his basement's wall. Ookook then placed black magic into the hole, converting it into a portal to Dimension 8. We don't talk about Dimension 8.

Daniel's Hole Arc
Daniel, son of Karen and William Holt, was born from The Hole. Miscellaneous meats and bones came through it, and Karen used these to build Daniel. After Daniel's younger brother, Alfred, threw him into The Hole and presumably killed him, The Hole's dark energy was unbalanced and The Hole was forced to close. This tore Daniel apart, but his soul still remained. This was when The Lost took Daniel in and brought him back to Dimension 7 as a roaming spirit of vengeance. With nothing but hatred and revenge on his mind, Daniel roams Earth, always on the lookout for Alfred, and always trying to protect the Holt family that created him.
