It was unexpected though, because pretty much every SD villain is played for laughs sometime in their presence, combined with the fact that Scooby and Shaggy are always comedic. The Entity was played seriously the entire time, and Scooby-Doo: Mystery Inc rarely had serious moments, with Professor Pericles being the most seriously taken villain before The Entity, and still wasn't even dark.
