Flipverse

The Flipped Universe, also known as the Second Seasonverse, Flipverse or Other World, is a parallel universe within the Seasonverse dimensional cluster in the multiverse. It is an alternate version of the Seasonverse that exists alongside the Prime Universe (Primeverse). It is separated from the Primeverse by a Quantum Barrier, and is an homage to the Mirror Universe from Star Trek. It can only be accessed through random dimensional rifts caused by the Barrier's endless cycle of decay and self-repair and is the home dimension of Team Season II. Owing to being more pervaded by darkness and evil than the Primeverse, the Flipverse is more dystopian than its counterpart, something that is reflected in Team Season II's behavior. History in the Flipverse is somewhat different, being marked by more unfortunate and dark events. Most entities in the Flipverse have equivalents in the Primeverse that are of different genders. Also, some entities are alive in the Flipverse but dead in the Primeverse. The same is true of the opposite.

After Team Season II come through the dimensional rift to the Primeverse, it closes behind them, leaving them trapped in the Primeverse. They determine that the only way to return to the Flipverse is to locate another dimensional rift and pass through it. Given the random appearances and short lifespans of the rifts between the Primeverse and the Flipverse, Team Season II ask their counterparts Team Season I and their allies Team Holliday, Superpsion and Event Horizon to help them find find a way to predict when and where the next rift will occur and make for the location to send Team Season II back to the Flipverse before the rift closes. After finding another dimensional rift with the assistance of their counterparts, Team Season II are able to return home to the Flipverse, after which all but one of them disappear from the series until season 7, when they return to assist their counterparts in battling Lord Lochindorb and his Flipverse counterpart, Lady Lochindorb. The Flipverse version of Spheron is seen later on after Quinn II's redemption and "death".
