First was the Marvel Studios: The First Ten Years line. Then Marvel 80th Anniversary, followed by the "Marvel Legacy" X-Men. And now it's the Infinity Saga.
- Iron Man - Mark III
- Avengers: Infinity War - Captain America
- Avengers: Age of Ultron - Quicksilver
- Thor - Odin
- Avengers: Endgame - Warrior Thor
- Iron Man - Iron Monger
- Thor: Ragnarok - Surtur
- Avengers: Endgame - Captain Marvel/Rescue
- Iron Man 3 - Happy Hogan/Mark XXI
- Avengers: Endgame - Mark LXXXV/Thanos
If that's the whole lineup, it's definitely not covering the entire Infinity Saga, which comprises 23 films. And it favours Endgame over everything else.
