Marvel

The Marvel Cinematic Universe (MCU) is a superhero film franchise built on Marvel Comics characters, launched with Iron Man in 2008. Across dozens of interconnected films and series it follows the Avengers — Earth’s mightiest heroes — through the Infinity Saga and beyond, all leading to some of the highest-grossing movies ever made.

The core Avengers

The MCU is anchored by a handful of heroes whose arcs run through the whole Infinity Saga. These are the ones everything else orbits.

    Started it all; “I am Iron Man”

  • Captain America

    Steve Rogers — the first Avenger

    Super-soldier, vibranium shield

  • Thor

    God of Thunder, prince of Asgard

    Wields Mjolnir, then Stormbreaker

  • Hulk

    Bruce Banner — gamma-powered

    Strongest there is when angry

  • Black Widow

    Natasha Romanoff — master spy

    No powers, all skill

  • Thanos

    The Mad Titan (villain)

    Sought all six Infinity Stones

The Infinity Saga in order

The first three phases of the MCU tell one connected story — the rise of the Avengers and the fight against Thanos. Here are the pillars.

  • Phase 1 — The Avengers assemble

    Iron Man → The Avengers (2008–2012)
  • Phase 2 — Cracks appear

    Ultron, the Winter Soldier, the first Guardians (2013–2015)
  • Phase 3 — The Snap and back

    Civil War → Infinity War → Endgame (2016–2019)
  • “I can do this all day.”

    Steve Rogers’ defining line
  • “We’re in the endgame now.”

    Doctor Strange, seeing one path to victory
  • “Avengers… assemble.”

What are the Infinity Stones?

The six Infinity Stones are the most powerful objects in the universe, each governing a fundamental aspect of existence: Space, Mind, Reality, Power, Time and Soul. Assembled together in the Infinity Gauntlet, they grant the wielder near-omnipotence.

The entire Infinity Saga is, at its heart, a race to control these stones — culminating in Thanos using all six to erase half of all life, and the Avengers’ years-long effort to undo it.

Things nobody knew

The details that separate a fan from a fanatic.

  • RDJ improvised the most famous line

    “I am Iron Man” at the end of the first film wasn’t fully scripted — it broke the comic tradition of a secret identity and set the MCU’s confident tone.

  • Thanos was teased for six years

    He first appeared in a 2012 Avengers post-credits scene, but didn’t become the main threat until Infinity War in 2018.

  • The shield-throw sound is a real object

    Marvel’s sound teams built the iconic vibranium clang from layered metallic recordings — it’s become instantly recognisable.

  • Wakanda was barely in the comics first

    The MCU expanded Wakanda far beyond its comic roots, and Black Panther became a cultural phenomenon and Oscar winner.

  • Spider-Man took a Sony deal to join

    Because Sony held the film rights, an unprecedented studio agreement was needed to bring Spider-Man into the MCU.

  • Endgame’s time-travel breaks its own rules

    The film deliberately mocks classic time-travel movies, then sets up its own logic — a favourite fan-debate to this day.
