Zero Lab

The Zero Lab (Japanese: ゼロラボ Zero Laboratory) is a facility located at the bottom of Area Zero in the Great Crater of Paldea.
==In the core series games==
The Zero Lab's door is initially locked by four separate locks, forcing the to visit the four Research Stations around Area Zero in order to unlock the entrance. When the door is first unlocked, a group of Paradox Pokémon comes out and attacks the player and their friends. Once the path has been cleared, the player is able to enter the laboratory.
The first floor of the Zero Lab contains the working space and living quarters of Professor Sada/Professor Turo. The area contains multiple small chambers used to study the crystals found in Area Zero, the Professor's research notes, whiteboards, a bed, and an elevator to the bottom floor. This is where the player first encounters Sada/Turo, who reveals that the real professor is dead and asks the player's help in stopping the time machine it and the Professor built together in order to stop an influx of Paradox Pokémon from destroying Paldea's ecosystem.
Taking the elevator down to the bottom floor allows the player to reach the time machine room, powered by the Terastal phenomenon. The AI warns the player that its programming will force it to attack the player when they try to stop the time machine, which indeed happens. After the AI has been defeated, a program called the Paradise Protection Protocol (Japanese: 楽園防衛プログラム Paradise Defense Program) takes over, taking control of the AI once more, sealing all Poké Balls in the room that are not registered to the Professor's ID, and gathering Terastal energy for the AI, which crystallizes parts of its body. This forces the player to use their / against the member of its used by the AI. Once the player has emerged victorious, the AI is once again freed, but it also realizes that its systems are so inseparably connected to the time machine that it cannot be shut down while it remains present. As such, the AI chooses to use the time machine to travel to a different era to stop the machine. Upon the AI's disappearance, the time machine shuts down permanently.
After the player has obtained the Indigo Disk, they use it to redirect the lab's elevator to the Area Zero Underdepths, rendering the time machine room inaccessible.

==Journal entry==
A journal entry describing the professor's efforts in creating a way to lock Poké Balls can be found on a desk. This system is later used to lock the Poké Balls of those not registered to Sada’s or Turo’s ID when Paradise Protection Protocol is activated.

==Trivia==
* Two photos can be found hanging on a whiteboard filled with equations, the first depicting a younger Arven playing with his , and the second solely depicting Maschiff.
** A smaller version of the first photo, with Arven's body partially out of frame, can be found in Arven's dorm room at Naranja Academy/Uva Academy.
** One of these photos may possibly be from the lighthouse lab on Poco Path, as it is the former home of the professor and Arven, and because an empty photo frame can be found inside.
* A shelf on the first floor of the lab appears to contain the professor's Gym Badges, as well as their Hall of Fame Badge from Naranja Academy/Uva Academy.
* The time machine inside the lab appears to have hexagonal walls, similar to that of a mentioned in the Scarlet Book/Violet Book and in the professor's journal entries.
