|Dale as he appears in 2) Friends.|
Dale seems to be a heavily plot-influential character in Michael's Camera.
Dale was the imaginary friend of Michael. Dale knew what was up. He died of unknown circumstances.
Somehow, through currently unknown means, Dale is able to apparently trap guardians like a forced in-habitation, demonstrated by it's confinement (or housing) of a Shard of Malek.
Cecil Xeneth refers to Dale as The Weed Doll in the Michael's Camera episode "Summoning an Arkn".
Strangely enough, Samael seems to know exactly how Dale can be used upon picking up the doll in the Michael's Camera episode "Out of the Nest".
