This is a canonical series of events that happens before, during, and after the events of Pokémon XY. Scroll down to see the timeline, or click below to warp to a specific point of time.
The early life timeline is uncertain, but we know that at some point, a boy dreaming about the future leaves a mysterious treasure in Couriway Town. Will the player character ever find it?
According to a lab associate in Professor Sycamore's lab, the Augustine traveled to Sinnoh as a young man to study under Professor Rowan. Due to the similar timeframe and age range, it's rumored that Augustine may be associated with Sinnoh's champion, Cynthia.
Augustine heads to the Tower of Mastery in Shalour City to study Mega Evolution. But he drops out, feeling he can’t meet the challenge. The order of these events aren't quite clear...
Professor Sycamore is the first character the player character meets when they boot up a new game: he introduces the player to the world of Pokémon, and asks a few questions to get their journey started. It's a very sweet start. The Pokémon he's depicted with is Gogoat, a new Pokémon introduced in XY, who has a long history of working together with humans. It's so nice!
Professor Sycamore's letter, meant for the player character's mom, is entrusted to Trevor. This letter is basically a permission slip for the player character to go on their big Pokémon journey. The letter has beautiful lettering and is even perfumed! He personally entrusts Trevor and Tierno with their Pokédexes, and asks them to deliver a Pokédex and Kalos starter to the other three. Professor Sycamore is so thoughtful and kind, making sure everyone gets a buddy! Even the player character's mom thinks he is very nice...!
The player character first meets in person Professor Sycamore in Lumiose City, guided to his laboratory by his assistants, Dexio and Sina. It's so exciting! He challenges them to a battle to test their skills and even gives them a second starter (Of Bulbasaur, Charmander, or Squirtle) and an associated Mega Stone for its final form. Like a Venusaurite! He is so generous and kind, helping the player grow, but also insisting that they take the time to figure out what their journey means to them! It's one of the more impactful speeches of the game!
Just before the player enters Reflection Caves, Professor Sycamore rings them up on the holocaster. He tells them to meet the Mega Evolution Guru in Shalour City! He encourages them to learn all about mega evolution and how it works. His love for mega evolution is so cool!
At the Coumarine City monorail station, the player character stumbles upon Professor Sycamore chatting with Diantha about mega evolution and ancient legends! They talk about how it might be tied to the bonds between Pokémon and Trainers! He also congratulates the player for using Mega Evolution for the first time and gives them HM02 Fly. That's so nice! Do you think he flies around Kalos too?
Professor Sycamore phones the player character over the Holocaster right after they obtain Lumiose' gym badge and asks them to meet him in Lysandre Café, the most chic and trendy place in town! Professor Sycamore is friends with Lysandre, and listens patiently to Lysandre's words, while also gently encouraging the player to come to their own conclusions about what was said.
The player character receives a message from Professor Sycamore post-Team Flare, asking for a face-to-face meeting in Couriway Town. After arriving, Professor Sycamore apologizes to the player and thanks them for their help. He's so sweet! He challenges them to a battle to see how far they've come, and after the battle, he hints at some kind of special surprise... he's so supportive and nice!
After the player beats the champion, Diantha, Professor Sycamore throws a huge parade in Lumiose City. He awards the player character and their friends the Honor of Kalos for their heroics against Team Flare! The celebration is just so cute, and it's amazing, because it ends on a note that not even Sycamore himself could anticipate!?
Professor Sycamore tells the player to meet him at Lumiose Station! He gives them a TMV Pass to board a train to Kiloude City, opening up a whole new adventure!
Professor Sycamore meets the player character in Anistar City after they defeat their rival in Kiloude City, and after a discussion of Anistar's mysterious sundial and stone energy, upgrades the player's mega ring! Now they can detect hidden mega stones around Kalos! Even after the credits, Sycamore is working away with his passion!
Back at his lab in Lumiose City, Sycamore evaluates the player’s Pokédex progress! He gifts them an Oval Charm for completing the three Kalos Pokédexes (Central, Coastal, and Mountain) and a Shiny Charm for the National Pokédex. He gets so emotional...
Sycamore even gets a shoutout in Pokémon Sun and Moon, which is so cool! Dexio and Sina reveal that Professor Sycamore was the one who discovered the Zygarde Cube, tying into his research on Zygarde from Kalos. I’m so proud of him for making waves even in Alola!
