Anti-Characters Universe

The Anti-Characters Universe was a reversed universe, home to people who are generally the opposite of their counterparts in the NES universe and TPUWCPADOSU.

State of inhabitants
After its destruction during The Great EvilBob Disaster, Anti-Urdrreem, Anti-SpongeBob, and Anti-Dreamare are the only ones known to be alive, although others may have survived through mysterious means, such as (Anti-)Baldimore Baldimore, whose mind currently resides in the head of his doppelganger, Baldi Patrick. In Return of the Food Wars, Anti-Views Kumnet was revealed as alive too.

People that do not have counterparts in TPUWCPADOSU are not called "Anti", but regular names, and those whose counterparts are dead tend to drop the Anti all together.

History
During his attack on TPUWCPADOSU, Anti-Sheldon Plankton opened portals between the two dimensions.

The universe was destroyed during the Great EvilBob Disaster, and most of its residents with it.

Legacy
The remains of the universe were eventually consolidated to form a brand-new Anti-Characters Universe by Cape Kragils. However, unlike the original, the anti-characters had normal names and the universe was named for the fact that people in this universe looked completely different from their TPUWCPADOSU counterparts, with completely different backstories.
