Asking for the Overwatch 2 hero release order gets you two different answers depending on where you start counting, because the roster has two distinct eras: a launch group that all appeared on the same day in 2016, and a long chronological tail added a few at a time ever since.
Short answer
Twenty-one heroes shipped together at launch in May 2016 and have no individual release order. Everything after that arrived one at a time — roughly three per year through Overwatch 1, then one every other season under Overwatch 2.
The launch roster (May 2016)
These all arrived at once, so any list that puts them in order is really just listing them alphabetically: Bastion, D.Va, Genji, Hanzo, Junkrat, Lúcio, McCree (now Cassidy), Mei, Mercy, Pharah, Reaper, Reinhardt, Roadhog, Soldier: 76, Symmetra, Torbjörn, Tracer, Widowmaker, Winston, Zarya and Zenyatta.

Overwatch 1 additions, in order
- Ana — July 2016, the first post-launch hero and still the template for how they were introduced.
- Sombra — November 2016, after an alternate reality game that ran for months.
- Orisa — March 2017.
- Doomfist — July 2017, built out of a lore tease that had been in the game since launch.
- Moira — November 2017.
- Brigitte — March 2018, the hero most associated with the shield-heavy era that followed.
- Wrecking Ball — July 2018.
- Ashe — November 2018, announced with the animated short that introduced her.
- Baptiste — March 2019.
- Sigma — August 2019.
- Echo — April 2020, the last hero of the original game.
The pattern is easy to see once it is laid out: three a year, spaced roughly four months apart, each with a public test build before release. Then a two-year gap while the sequel was being made.

Overwatch 2 additions, in order
- Sojourn, Junker Queen and Kiriko — October 2022, all three at the Overwatch 2 launch.
- Ramattra — Season 2, December 2022.
- Lifeweaver — Season 4, April 2023.
- Illari — Season 6, August 2023.
- Mauga — Season 8, December 2023.
- Venture — Season 10, April 2024.
- Juno — Season 12, August 2024.
- Hazard — Season 14, December 2024.
The rhythm is deliberate: a new hero on every even-numbered season, which works out to one roughly every four months — the same cadence as the original game, just expressed in seasons instead of patch numbers. Seasons after those continue the pattern, so the newest name on the roster is always the one from the most recent even season.

Why the order matters more than it looks
Release order is a decent proxy for design philosophy. The launch roster is built around simple, readable kits. The 2017–2018 additions add layered cooldowns and sustain, which is what eventually made shields dominant. The Overwatch 2 group is built for 5v5 rather than 6v6, which is why tanks from that era have so much more self-sufficiency than Reinhardt or Winston do.
If a hero feels oddly strong or oddly clumsy compared to the rest of their role, checking where they land in this list usually explains it.
Overwatch FAQ
How many Overwatch heroes are there?
Forty-plus and still growing, counting the 21 from launch, 11 from the rest of Overwatch 1, and everything added since Overwatch 2 began.
Which hero was released first?
Ana, if you mean the first added after launch. Everyone before her arrived on day one.
Are any heroes unavailable now?
No. Every hero released remains playable, though several have been reworked heavily enough that only the name survived — Orisa, Doomfist and Bastion in particular.
Do new heroes cost anything?
Heroes unlock through the season's free track or are granted outright once that season ends, so no purchase is required to access one eventually.
The short version: one launch day, then a new face every few months for nearly a decade, which is why the roster now looks so much less tidy than it did in 2016.
