The Shambling Corporate Presence is a demon who first appears in Reality 2.0.
Since his original "appearance" is during the Reality 1.5 segment of Reality 2.0, what he actually looks like only becomes clear in Ice Station Santa. In that episode, he is accidentally shipped to Santa (instead of Satan) and uses the opportunity to engage in demonic possession and spread general misery. In What's new, Beelzebub?, he is doing his actual job (or pretending to, at any rate) in hell.
While the Shambling Corporate Presence is supposedly good at optimizing efficiency, he seems to spend more time playing Mimesweeper than working. This may be just why the Soda Poppers transferred him though, this combination allowing them to make Hell less efficient while making Satan take the blame.
