Overwatch used BlizzCon 2026 to introduce Doctrine, a vampire-inspired Support hero (Hero 54) with an Infuse kit built around healing/damage hybrid fire and drone utility. Polygon published a same-day kit/hands-on wrap; first-party Blizzard Overwatch BlizzCon notes and the ceremony roundup confirm a limited Hero Trial through September 14, 2026, with Doctrine joining the roster in Season 5 on October 6, 2026.
Kit color (attribute to Polygon/Blizzard trial build, not as final forever balance): Eternal Scepter heals allies and damages enemies; Infuse power-spikes the next ability; Shrouded Momentum mobility; Invigorating Drones ally buffs; Deliverance ultimate swarm. Season 5 framing in Blizzard’s ceremony package also points to Roadhog and Sombra reworks and map Watchpoint: Grimsvotn as part of the wider season story, with The Reign of Talon arc wrapping — keep those as season context, not as Doctrine-only claims.
Platforms for the live Overwatch service remain the multiplat set players already use: PC, PlayStation, Xbox, and Nintendo hardware in the current client footprint. This filing does not invent a new exclusive SKU or a separate Doctrine-only download.
Why it matters: a weekend Hero Trial already live is the fastest playable BlizzCon Overwatch beat, and locking Season 5 to October 6 gives ranked/queue audiences a hard season clock rather than a vague “sometime in October.” Support players and Reaper-minded DPS queued into support both get a clear trial window before the full season push.

What we are not saying: no claim Doctrine’s trial balance is final forever, no invented Season 5 day other than the October 6 lock used here, and no Netflix/adaptation digression.
Play the Hero Trial through September 14, then expect Doctrine’s full roster join with Season 5 on October 6, 2026.
