Pokémon Go's Celebi is the game's second Mythical Pokémon, and was first made available in a different way to any other creature we've seen so far.
However, there's another key difference - the quest has debuted first for those attending this year's Go Fest in Chicago.
Celebi has also had it's shiny form released into Pokémon Go. Shiny Celebi was first released during the December 2020 Secrets of the Jungle event, which unlocked the special research quest Distracted by Something Shiny.

How Celebi first debuted in Pokémon Go
Before August, only those attending this year's Pokémon Go Fest in Chicago were available to catch Celebi.
Ahead of the July event, datamining (via The Silph Road subreddit) had revealed a Special Research quest for attendees, which confirmed how the following went down:
- A total of five steps to complete
- Challenges to hatch an Egg, earn Buddy Candy and visit PokéStops
- Catching Unown, Plusle and Minun
- Story text hinting at Celebi's time travelling abilities
Once attendees registered for the event (players have to spin a PokéStop and scan a barcade to register their account as attending) they could get started.
Another hint Celebi was going to be at Go Fest is through a sponsored tweet from Mystic7, showing a silhouette of the Pokemon in an event invite:
The datamines turned out to be true, with Celebi able to be caught after a day's play:
The Season of Adventures Abound is here! Currently the Out to Play event is running. You can also work on the Timed Investigation: Master Ball quest and compete in the Go Battle League. Be sure to compete in Shadow Raids, complete Routes, use Daily Adventure Incense for the chance of encountering Galarian Articuno, Galarian Zapdos and Galarian Moltres. This incense may also give you encounters with other rare Pokémon in Pokémon Go.
Celebi stats and what else you need to know about Celebi in Pokémon Go
Celebi is Pokémon Go's second Mythical Pokémon, and the last Pokédex entry in Gen 2. While Legendary Pokémon are powerful beasts that are caught in game through specific steps, Mythical Pokémon can only be added to the game by acquiring it from real-world giveaways, and later in the series, online events.
Celebi is both Psychic and Grass Type, leaving it open to attack from Fire, Bug, Dark and Ghost attacks. Between that and fairly underwhelming stats, Celebi continues the trend that Mythical creatures aren't great competitive Pokémon in Pokémon Go.
However, its rarity alone makes it well worth the time and effort in completing the Special Research questline. After all, there is no way to trade it.
There are more to come, too. Like Legendary Pokémon, each generation adds one or two of these creatures - such as Gen 3's Jirachi and Deoxys - and it's assumed these creatures will be added to the game as part of their own Special Research quests at some point in the future.
