Marvel Cinematic Universe
X-Men: First Class
Before any of it, two young men find each other and try to stop a war nobody else can see.
A separate universe from the main line. Deadpool & Wolverine made that connection explicit rather than tidy, so this order is a reading of it, not a ruling.
Where It Sits
- In-Universe Order — number 100 of 158 on the timeline. After X-Men Origins: Wolverine. Then X-Men: Days of Future Past.
- Release Order — number 25 of 158 on the timeline. After Thor. Then Captain America: The First Avenger.
