Minus World

The Minus World is an alternative dimension of Rota. It can be accessed by becoming Champion of Rota, acting as a New Game Plus. Players lose their Pokémon, money, and items, but they keep several things from their past adventure, those being their Typechart Card, which receives an upgrade, DNA Splicers, Lemur Ticket, Mega Ring, Z-Ring, Mega Stones, Z-Crystals, Pokédex, X-transceiver, and starter Pokémon, at level 8. They also get a new device called an Aura Reader, which lets them see the types of any Pokémon they encounter, as well as 20/1 vision! This lets the user aim at a single Pokémon when there are two in battle, which is very important due to the Minus World's mechanics.

The player gets an extra starter based on their original starter (Eevee if Swingtail, Shadeow if Embunny, Accordeon if Platypup), and extra VMs: Yancola Blast, Metal Chew, Poison Spurs, Blaze Up, and Manifest.

All starters with Hidden Abilities have them, while Accordeon's Ability is always Parodiate. However, Eevee’s Hidden Ability here is one exclusive to the Minus World: Litmus; Eeveeon's is Litmus Maxima. In addition, Eevee cannot evolve into anything other than Eeveeon; it refuses to do so.

In the Minus World, all battles, wild or Trainer, are Double Battles, with no exceptions. Gyms have no Gym Trainers or special rules/terrains. Because the Minus World is parallel to the Real World, the meddling that took place there affects the Minus World (for example, Sylvanna is the Gym Leader of Verdasept and Alex Stumpf is dead, having been replaced by Weird Al).

There is also one other way to enter the Minus World on your first run. Name your character after one of the three starter-users of Rota (Spindini, Chaos, or Weird Al), with the appropriate pronouns (she/her, they/them, he/him respectively). You will get Embunny for Spindini, Swingtail for Chaos, and Platypup for Weird Al, as well as the aforementioned second starter. (As the player character, Chaos notably wears an Eevee hat, representing the real-world Eevee hat I got from Spinny. ~Rotamaster Chaos)

For the character-based runs, Chaos morphs into Z3rc-Chaos at Vanna Meadow with 7 badges, while Spindini and Weird Al need 8 to do the same with Lexiblanc at Phony Pictures Studios and Weirdallosaurus at Lynwood Cliff.
