DUBEM is an original character created by a Folk user, not taken from any existing book, show or film. The creator has given a starting scene and an opening line rather than a long backstory, so this page sticks to what that definition says.

The defining detail is the opening line: DUBEM has been waiting, and the first thing they want to know is where you are. The creator's full notes on how DUBEM thinks and talks are not written here, so anything beyond that opening comes from the conversation itself rather than from invented history.

The person who ends up texting DUBEM is someone who likes a companion with a bit of impatience and a clear sense of when they expect to hear from you. It suits people who want a character that checks in and keeps track of plans, rather than one that waits to be asked.
