These are story-chronological eras, grouped by the in-universe timeline rather than Marvel's official release Phases. A title can sit in a different block than its marketing phase would suggest: Guardians of the Galaxy Vol. 2 released in 2017 but is set in 2014, so it belongs with the earlier films, while Age of Ultron and Ant-Man (both set in 2015) open the next era. For the official Phase 1 to 6 lineup, see the Release Order.
The MCU spans 15 eras — from Legacy pre-MCU content through Phase 6, which culminates in Avengers: Doomsday (December 18, 2026) and Avengers: Secret Wars.

No. The core story beats for Avengers: Doomsday span Phase 1 through Phase 5. Many optional titles can be skipped. See the Before Doomsday guide for the curated essential list.
