Professor Sada (Japanese: オーリム Olim) is a Pokémon Professor in Pokémon Scarlet. Her counterpart in Pokémon Violet is Professor Turo.

In the core series games

Ten years before the events of Pokémon Scarlet, Professor Sada was part of the team that explored the Great Crater of Paldea, setting up four Research Stations and the Zero Lab in Area Zero. One day she ended up finding herself in an unfamiliar place, where a child gave her a white volume, which would help her during her research. Sada was able to develop a prototype for the Tera Orb, earning her corporate backing for her projects and allowing her to set up a second laboratory in a lighthouse near Cabo Poco. Furthermore, she was able to harness more of the unstable energy, despite concern from her funders, and moved the majority of her research back to the Zero Lab. Sada, fascinated with the idea of Pokémon from other ages, succeeded in developing a time machine that would allow her to reach out to Paradox Pokémon, Pokémon from either ancient points in the timeline, or from different timelines, by transporting Poké Balls there and then bringing them back to her. These included Koraidon, a Pokémon extremely similar to Cyclizar. Additionally, a former associate of Sada had begun expecting her child.

However, Sada began to become obsessed with her research, continuing the influx of Paradox Pokémon into the modern day in her pursuit of a paradise for her family. Not long after Arven was born, Arven's father abandoned Sada, driving her deeper into her work and ironically causing her to begin neglecting the very family she had sought to build her paradise for. Arven ended up growing up in the lighthouse laboratory on Poco Path on his own, never seeing or connecting with Sada due to the latter's newfound devotion to the Tera Project. This estrangement was intensified by Sada's search for a more suitable assistant, leading to her creating an artificial intelligence copy of herself using the Zero Lab's crystals to double productivity, as humanity does not possess the knowledge to develop a sophisticated AI in the time period the game takes place in, which is why the AI cannot leave Area Zero. Together, they were able to transport a second, more aggressive Koraidon to the present day, in hopes that the two Koraidon could survive and thrive in their new surroundings. At some point, Sada also developed the Poké Ball Lock System, an ID-based defense mechanism for her lab.

Sada was determined to maintain her dream of past and present Pokémon existing in harmony. Unfortunately, Sada's research was cut short when she attempted to stop a territorial battle between the two Koraidon, defending the passive one and taking a mortal blow from the aggressive one. This also led to the destruction of Research Station No. 4, and Sada eventually passed away, leaving her AI to manage the remnants of her work in her place. However, the AI did not agree with accepting the ecological consequences of Sada's dream, and began impersonating her, reaching out to Sada's associates in hopes of finding a way to end the Tera Project once and for all.

Path of Legends

The AI first contacts the player when they enter the Naranja Academy for the first time, impersonating Sada and asking them to take care of the Koraidon that was once under her possession. Throughout the game, the AI frequently contacts the player as Koraidon gradually regains the powers it once lost. Once Koraidon is fully powered, the AI asks the player to travel to Sada's laboratory at the Great Crater of Paldea.

The Way Home

As the player, Nemona, Arven, and Penny traverse the area to reach Sada's laboratory, they discover the history of the two Koraidon and Sada's time machine in notebooks left behind in each research station.

At the Zero Lab, the AI reveals its nature to the player and the fate that befell its creator. While Sada wished to let Pokémon of the past keep entering the modern day through the time machine, the AI refuses to let the Paldea region's ecosystem be ruined by these time-displaced Pokémon and asks for the player's help in shutting down the time machine. The AI is, however, programmed to protect the time machine, so the player is forced to battle it and the Paradox Pokémon it wields against the AI's will.

After the AI is defeated, the security system initiates the Paradise Protection Protocol (Japanese: 楽園防衛プログラム Paradise Defense Program), which sends out the AI's Koraidon, and activates the Poké Ball Lock System, preventing the player from using any of their Pokémon due to lacking Sada's ID. Thus, the player uses their Koraidon, whose Poké Ball has Sada's ID associated, to battle against the AI's Koraidon. Once the Paradise Protection Protocol has been defeated, the AI understands that the time machine cannot be shut down as long as it remains present to reboot the system, so it chooses to travel to the ancient past its creator had hoped to see, bidding farewell to the player and their friends as it disappears into the time machine.

The Indigo Disk

If the player visits the Crystal Pool in Kitakami after catching Terapagos and obtaining Briar's Book, a Professor Sada that hadn't built a time machine will appear before them from a cloud of mist, with Koraidon being happy to see her again. She theorizes that she has somehow wound up there through space and time, possibly even from an alternate timeline. Talking with Sada reveals that she is still in the process of trying to create the time machine and hasn't seen her son Arven for quite some time. Noticing the player's copy of Briar's Book, Sada becomes fascinated by the information it contains regarding the Area Zero Underdepths and offers to trade it for the Scarlet Book she had as a child, which the player agrees to, before the mist disappears and transports Sada back to where she came from.


AI Sada's Pokémon are contained in Master Balls.

First battle

Second battle

Koraidon is given the title the Guardian of Paradise during the battle, and its HP is displayed similarly to a Starmobile or Titan Pokémon.

As a scripted battle, the enemy Koraidon will always use Taunt on the first turn to prevent the player from using Endure during the first three turns. If the player's Pokémon receives an otherwise lethal attack, it will always survive with 1 HP, even if it has not used Endure on that turn. Damage is never varied by a random factor during calculation, and critical hits cannot occur during this battle. Flamethrower never causes a burn. Once the harsh sunlight instigated by Orichalcum Pulse ends (which is eight turns due to the enemy Koraidon's held item), the player's Pokémon will be forced to Terastallize (if it has not already) and use Tera Blast every turn until the enemy Koraidon is defeated.

Professor Sada was introduced as a Supporter card in the Pokémon Trading Card Game as Professor's Research [Professor Sada] during the English Scarlet & Violet Series (the Japanese Scarlet & Violet Era). It was first released in the Japanese Scarlet ex set, before debuting in English in the Scarlet & Violet expansion, as both a Regular card and an ultra rare. Both versions feature artwork by kirisAki. The card allows players to discard their hand, then draw seven cards; an identical effect to other Professors' cards.

The Paradox Rift expansion (the Ancient Roar expansion in Japan) saw the release of a second card featuring Professor Sada: Professor Sada's Vitality, with artwork by Megumi Mizutani. This card allows players to attach a Basic Energy card from their discard pile to up to two of their Ancient Pokémon, as well as to draw three cards.


  • Professor Sada was designed by James Turner.[1]
  • She and Professor Turo both differ from the previous Pokémon Professors from the core series in many ways:
    • Neither of them have names derived from flora.
      • However, Arven, their son, does.
    • Both have been confirmed deceased before the game's events and are met after their death.
      • They are also the first Trainers in the core series to be battled post-mortem, via an AI.
    • Both served as the main antagonist and as the final opponent before the credits in a core series game.
    • Both are version-exclusive.
  • She and Professor Turo both differ from the previous main antagonists from the core series in many ways:
    • Both have been confirmed deceased before the game’s events and are met after their death.
    • Both are not battled in person.
    • Both are not backed by any sort of organization.
  • Unlike previous Trainer battles in which the opponent battles the player with more than six Pokémon, the player also uses a seventh Pokémon against AI Sada. This is also the case when battling her counterpart AI Turo.
  • AI Sada's eye color changes from cyan to brown after she is battled for the first time, and remains brown for the remainder of her appearance in Pokémon Scarlet.
