1. Pym Particles
   Midi-chlorians
2. Deathly Hallows
   Infinity Stones

There's a reason why they call the MCU collection the "Infinity Saga." The majority of the plots revolved around the retrieval of the "infinity stones," which collectively hold the power over all of life. In the comics, the original term is "infinity gems" because they're gemstones.

1. Nick Fury
   Phil Coulson
2. Howard Stark
   Chester Phillips

The 2019 solo hero film "Captain Marvel" explains how Nick Fury became the default boss of The Avengers. His "origin story" in this film ties up with his last action in "Avengers: Infinity War" right before he got turned to dust. No spoilers, but watch out for a cat and what it does to him!

1. Vibranium
   Plutonium
2. Uranium
   Adamantium

We first hear of the MCU's wonderful element called "vibranium" extensively when Tony Stark's dad bragged of using it to create Captain America's shield. This fictional element takes center stage in "Black Panther," as we discovered that it's abundant there in Wakanda.

1. Johann Schmidt
   Erik Selvig
2. Peter Parker
   Clint Barton

Hawkeye is one of the Avengers' core members in the MCU. We briefly see him as Clint Barton in "Thor." In "Avengers: Age of Ultron," we saw him as a family man when the heroes temporarily took shelter in his house. Losing his family in "Infinity War" prompted him to turn dark in "Endgame."

1. William Hurt
   Sam Rockwell
2. Vin Diesel
   Josh Brolin

Vin Diesel could have easily played any MCU hero or villain, but his schedule didn't permit it during that earlier time. In an interview, he said that the Marvel executives offered him to be the voice of Groot instead. Hesitant to play "only a tree," it was his children that convinced him to do the role.

1. T'Chaka
   Dormammu
2. Loki
   Drax

Loki is one of those characters you love but you also hate; then he turns around and does something lovable while being good or being bad! Tom Hiddleston's nuanced portrayal of this Asgardian character adds to this unique characterization.

1. "Iron Man 2"
   "Thor: Ragnarok"
2. "Avengers: Age of Ultron"
   "Doctor Strange"

Valkyrie's Asgardian comics character is bisexual and, just like Thor, she had a romantic relationship with a human female. She first appears in the MCU in "Thor: Ragnarok," and we saw her back up Captain Marvel in a climactic all-female featured fight scene in "Avengers: Endgame."

1. Chris Pratt
   Chris Evans
2. Chris Hemsworth
   Chris Pine

"Guardians of the Galaxy" entered the MCU in 2014 with Chris Pratt in the lead. His Star-Lord character's back story originated in the late '80s to show his human origins. His alien heritage is unraveled in this film and in the 2017 sequel.

1. Aurora
   Meteor
2. Nebula
   Asteroid

Gamora's brown-nosing android sister Nebula appeared in "Guardians of the Galaxy" as a villainous character. But she got her MCU redemption arc when she sided with the good folks and helped them destroy Thanos. Her storyline delivered crucial plot points which made "Avengers: Endgame" possible.

1. Ava Starr
   Irani Rael
2. Wanda Maximoff
   Natasha Romanoff

In the comics, Russian spy Natasha Romanoff's original design was as a nemesis to Iron Man who later gave up her Russian ways and joined S.H.I.E.L.D. to do "good deeds." In the MCU, though, we saw her as a member of S.H.I.E.L.D. already when she first appeared in "Iron Man 2."

1. Psychiatry
   Cardiology
2. Dentistry
   Neurosurgery

A neurosurgeon works on the body parts associated with the nervous system. Aside from the brain and spine, this basically covers working on all arteries and veins. Such sensitive work needs nerves of steel; Dr. Strange sadly lost his, prompting his character's new journey for healing.

1. CD
   iPod
2. Cassette tape
   Vinyl

Since he came of age in the '80s, Star-Lord experienced the analog joys of sound tripping with cassettes played on a tape deck. A portable Walkman device with that unmistakable orange foam-covered headphones played his mixed tape. That was how older folks created a playlist back in the day, kiddos!

1. Ancient One
   Vision
2. Captain Marvel
   Ultron

Since "Avengers: Endgame" finished filming before "Captain Marvel" started filming, analysts pointed out the differences in Brie Larson's characterization of this hero. For one, "Endgame" Marvel wore more makeup, which goes against her established natural look in the stand-alone movie.

1. "I've come to bargain."
   "Hail Hydra!"
2. "I am Groot."
   "Smash!"

In an "Avengers: Endgame" sequence, Captain America played on the aspect of knowing "Hail Hydra" when they time-traveled to retrieve an Infinity Stone. Hydra's terrorist-focused R & D origins unfolded in Captain America's own 2011 film.

1. Tobey Maguire
   Andrew Garfield
2. Both of them
   None of them

Tobey Maguire was the non-MCU face of Spider-Man in the 2000s under the direction of Sam Raimi. The early 2010s saw a non-MCU reboot with Andrew Garfield in the lead. The MCU Spider-Man first appeared in "Captain America: Civil War" before spinning off into his own stand-alone MCU film.

1. Eric Bana
   Edward Norton
2. Both of them
   None of them

Eric Bana became the Hulk in director Ang Lee's 2003 non-MCU version. while Edward Norton appeared in the 2008 MCU version. Another Hulk actor was also in that MCU version: '70s TV Hulk, Lou Ferrigno, who provided the voice for the green guy whenever he's on screen.

1. "Guardians of the Galaxy Vol. 2"
   "Thor: The Dark World"
2. "Captain America: Civil War"
   "Spider-Man: Homecoming"

Even heroic groups form factions; this happened when the Avengers took opposing sides in "Captain America: Civil War." Not surprisingly, leading one side was Tony Stark, while the other was Steve Rogers. The rest of the Avengers, along with other recruits, also took sides behind Iron Man or Captain America.

1. MJ Jones
   Hope van Dyne
2. Wendy Lawson
   Carol Danvers

Hope van Dyne's connection to the MCU might be tighter than Ant-Man's since her parents worked for S.H.I.E.L.D. Her dad created the Pym Particle, which makes it possible to shrink or enlarge humans. This technology was crucial in the "Avengers: Endgame" in their plan to retrieve the Infinity Stones.

1. Red Skull
   The Collector
2. Thanos
   Quicksilver

In the Marvel comics, they classify Thanos as a "supervillain," since this character type gets pitted against superheroes. But in the MCU, his villainous portrayal has a more philosophical aspect. This is evident in the way he delivers speeches to rationalize his plan of wiping out the universe.

1. Jane Foster
   Betty Ross
2. Peggy Carter
   Maria Hill

To continue its "transmedia storytelling" nature, MCU developed Peggy Carter in interlinked TV series. One was in "Agents of S.H.I.E.L.D.," while the other was in her own "Agent Carter" show. Hayley Atwell portrayed her; she also appears in Captain America's MCU film storylines.

1. N'Jadaka
   W'Kabi
2. T'Challa
   Zuri

The African king T'Challa succeeded his father-king T'Chaka in "Black Panther." But we first saw this Wakandan father and son tandem in "Captain America: Civil War," where the elder king got killed in a United Nations explosion.

1. Co-write
   Cameo
2. Creative producer
   Showrunner

Stan Lee filmed several MCU cameos before his death; that's why you can still spot him in "Avengers: Endgame." He's the car-driving '70s hippie that Tony Stark and Steve Rogers passes by on the way to the New Jersey military base. In "Captain Marvel," Carol Danvers smiles at him inside a subway.

1. Forest Whitaker
   Don Cheadle
2. Michael B. Jordan
   Chiwetel Ejiofor

Actor Terrence Howard originally played the Jim Rhodes character in "Iron Man" but without donning the War Machine ensemble yet. It was Don Cheadle who had that chance in the "Iron Man" sequels and in the subsequent MCU films.

1. J.A.R.V.I.S.
   FRIDAY
2. Quicksilver
   Ultron

"Avengers: Endgame" introduced to us the real-life Edwin Jarvis, butler and driver to Howard Stark. He was Tony Stark's inspiration in creating the artificial intelligence entity J.A.R.V.I.S., which acted as his "assistant" of sorts. The acronym stands for "Just Another Rather Very Intelligent System."

1. Mickey Rourke
   Robert Downey Jr.
2. Michael Douglas
   Paul Rudd

Robert Downey Jr. portrayed the iconic silent-film star Charlie Chaplin in the 1992 biopic "Chaplin," where Marisa Tomei played actress Mabel Normand. The two reunited in the MCU playing Tony Stark and Peter Parker's Aunt May.

1. A shared universe
   Magical enemies
2. Time travel
   Heroes with parental issues

MCU actually goes beyond mere cross-platform storytelling; it's technically considered as "transmedia storytelling" because of their shared universe. Their interconnected stories where characters appear and continue their story arcs from one movie to another is what makes it "transmedia."

1. "I can do this all day."
   "Wakanda forever!"
2. "I love you 3,000."
   "We are Groot."

Spoiler alert: this line came from Tony Stark's young daughter in "Avengers: Endgame" which he later uses as his goodbye line. Katherine Langford, who played Hannah Baker in "13 Reasons Why," portrayed an older version of this daughter. Her scenes got cut when producers decided to tighten the story.

1. An army pet name
   Childhood game term
2. As her aviator call sign
   Her best friend's secret code word

In "Captain Marvel," the younger Nick Fury noticed Air Force pilot Carol Danvers' call sign "Avenger" painted on the side of her jet. Military pilots also have their call signs on their uniforms and other items. Tom Cruise's 1986 movie "Top Gun" highlighted this call-sign use prominently.

1. Mother
   Sister
2. Aunt
   Wife

Angela Bassett essayed the role of Queen Mother Ramonda in "Black Panther," while Rene Russo played Queen of Asgard Frigga in "Thor." As parents of the titular heroes, they served as caring mothers and wise counsel to their often conflicted children. They both appeared in "Avengers: Endgame."

1. Iron Man
   Hawkeye
2. Captain America
   Hulk

To turn muscle-ripped "Captain America" into skinny Steve Rogers (or, well, the other way around!), the visual-effects studio combined old-school in-camera tricks with today's tech. Chris Evans crouched to fit Steve's short height. They later digitally re-scaled him painstakingly, somewhat similar to resizing a picture on Photoshop.

1. Estonia
   Latvia
2. Sokovia
   Wakanda

From her accent alone, one can guess that Wanda Maximoff originated in Eastern Europe; her surname also sounds like it. She hails from the fictional MCU-created country called Sokovia. In "Avengers: Age of Ultron," a map shows that Sokovia is a small landlocked country near the Czech Republic.

1. Jon Favreau
   Michael Douglas
2. Bradley Cooper
   Anthony Hopkins

If you noticed Tony Stark interacting with friend and colleague Happy Hogan, then you just spotted two-time MCU director Jon Favreau. He helmed the first two "Iron Man" films and appeared in the funeral scene in "Avengers: Endgame" and in other MCU films with Tony Stark and Peter Parker storylines.

1. Idris Elba
   Martin Freeman
2. Anthony Hopkins
   Hugo Weaving

In the BBC's "Sherlock," Benedict Cumberbatch played the titular detective character, while Martin Freeman played Dr. John Watson. "Black Panther" showed how his MCU character, CIA agent Everett Ross, links with T'Challa's storyline. But we see him first in "Captain America: Civil War."

1. S.H.I.E.L.D.
   Hydra
2. Avengers
   Asgardians

If you noticed in the "Avengers: Endgame" end credits, the original Avengers team included a literal "signing off" when their names flashed on-screen. The actors whose signatures flashed above their names were the ones who held the MCU story together as the Avengers, the core heroes of this saga.

1. Alan Rickman
   Robbie Coltrane
2. Kenneth Branagh
   Richard Harris

Knighted Shakespearean actor Sir Kenneth Branagh sometimes crosses over to the director's side. In the MCU, he helmed 2011's "Thor," but his directing career started way back in 1988. Among his recent directed films are "Cinderella," "Jack Ryan: Shadow Recruit" and "Murder on the Orient Express."
