YMMV / The Q Continuum

• Alternative Character Interpretation: When Q recalls his past visit to Deep Space 9, he claims that he found the station tedious to explain why he never went back, but Picard and Riker mention the reports they've heard that Sisko punched Q in the face, suggesting that Q didn't return because he was intimidated rather than because he found it dull.
• Complete Monster: 0 is a nearly omnipotent extradimensional entity with a penchant for torturing and exterminating "lesser" species under the guise of testing them. Having been exiled from his home plane eons ago, he manipulated a young Q into letting him into the Milky Way galaxy and guiding him to more "subjects". He attempted to enslave the Coulalakritous energy beings for warp speed transportation, and in response to their successful resistance he compressed them into a lump of ice--which they remained as for 2,000 years—only stopped from going even further by Q's own intervention. Gathering a group of similar beings, 0 had them engineer a decades-long civil war in the Tkon Empire, and after the Tkon managed to make peace, he personally sped up the death of their sun, consuming all seven trillion inhabitants, for which the Q Continuum banished him from the galaxy. In the present, 0 manipulates a scientist into breaching the galactic barrier to allow him to continue his depredations as well as take revenge on Q for turning on him.
• Never Live It Down: Sisko decking Q during "Q-Less". The entity's annoyed that Picard and company know of the incident (and that Picard's half-wishing he'd followed Sisko's lead back during "Encounter at Fairpoint").
