Professor Sycamore

Professor Augustine Iemitsu Sycamore is the main professor of the Kalos region. He's from Lumiose City, Kalos. He was previously involved with the Science Division of the Tekiyoku, but quit. He knows Alain from the past and ran into him with the rest of the main Mokusetsu members to give information helpful to finding Serena's home.

Background
5 years before the start of the series, Professor Sycamore was contacted by Dr. Zager and his Science Division of the Tekiyoku. He was one of the several scientists who were not Tekiyoku members who were reached out to in order to help with the division. Sycamore offered his lab for the division to use for experiments, because there was no lab in the Tekiyoku Headquarters. Sycamore isn't evil, but only did this because he was offered substantial money by the division.

His lab was used for experiments done to Serena, who was 13 when these experiments started. He learned all about Serena's situation, including how she was supposed to only be kept for 2 months, but this was extended due to the division's malicious intentions to advance the Tekiyoku. They wouldn't let Serena go and she was desperate to go home and see her mom, who was worried sick about her daughter.

Sycamore witnessed various experiments done to Serena, including one that tested a new type of amnesiac medicine. It caused her to lose some of her memory, but not all. She forgot parts of her name and her mother's entire name. It's not permanent, but it lasts for a few years.

He also witnessed an experiment done where the division tried to see if Celebi could link to a human's heart and make that human be able to teleport to another place on their own at will. Dr. Zager believed that being connected to Celebi by spending long periods of time with it would help, along with some "magical" potions he invented. Celebi was left alone with Serena for periods of time. The experiment didn't work, however. How the Tekiyoku encountered and temporarily captured Celebi for this is currently unknown, but it was set free after this experiment attempt.

During the times of these experiments, Sycamore met Alain, who was still in the Tekiyoku at this time. Alain was relatively new to science and was observing other non-human experiments in Sycamore's lab. He wasn't really there during actual experiments done on Serena, though, so he didn't know her.

Sycamore became tired of seeing the injustice done to Serena and decided to withdraw from helping the division after the 6th month of kidnapping Serena. The Science Division simply looked for another lab to use.

After this, since the two weren't involved with the Tekiyoku anymore, Sycamore and Alain met up later to reconnect and become friends. Sycamore ended up helping Alain set up his own lab during the 3-year waiting period for the Plates to stop being dormant. Alain ended up being successful with this lab, making enough money to fund his entire trip to get the Plates. He has assistants running the lab now while he's gone.

Present
When Serena was with Ash, Alain, Dawn, Clemont, and Bonnie in Kalos, she described the location she was kept in during the initial months of her kidnapping. Alain recognized some of her descriptions as the lab of Professor Sycamore. Alain contacted Sycamore to meet him in Vaniville Town, Kalos, where they currently were.

When Sycamore arrived, Alain had him explain what he knows about Serena. Sycamore told them all about who she is and how she was taken from her home, but not returned after 2 months. He told them about the experiments done to her, including why her memory isn't fully intact. He told them about the Celebi experiment as well.

There was one major thing he couldn't help with, however. Sycamore knew that the Science Division of the Tekiyoku relocated Serena's mother, Grace, to another house after the experiments first started. They didn't tell Serena this. This was done to keep Serena from being able to find her mom if she ran away somehow. The division wouldn't tell the location of her mom to non-Tekiyoku members, so Sycamore didn't know where Serena's mom was.

Based on another remark by him at the end, and Alain's reaction, he seems to know about Alain's past, including parts that Alain would preferably not speak about.

Personality
Regardless of his involvement with the Tekiyoku, Professor Sycamore is a kind guy with a good heart. He's laid-back and goes with the flow of things, remaining calm in unfavorable situations. His acceptance of the money for providing his lab to the Science Division is likely because he needed the money to help with paying the taxes to the Tekiyoku and not for greed.

He's very helpful and remembers things well, since he was able to recall as much of the information about Serena as he could. He offered for the Mokusetsu to let him know if they need any more of his help in the future.
