Scarlet Johansson recently teased that Avengers: Infinity War would include a scene featuring 32 Marvel characters, and the Russo brothers once remarked that the film could include a whopping number of 67 characters. Considering this information and the list of characters already confirmed to appear, we know that the cast is going to be gigantic.

However, we shouldn't put it past Marvel to include even more characters that we don't even know about yet. Guardians of the Galaxy Vol. 2 featured a slew of surprise characters as well as the original team of Guardians. Will Marvel pull off something similar with Avengers: Infinity War?

We could name dozens of characters that fans are hoping will finally get their Marvel Cinematic Universe debut, but not everyone can be included, despite what the current cast list might suggest. If any unannounced characters make their way into the film, we should expect them to be characters relevant to both the film's story and the source material.

Since the film will follow the signing of the Sokovia Accords, we can think of a few Marvel characters who would fit this storyline perfectly. Depending on how closely the movie is connected to Infinity Gauntlet and Infinity War, there's even more characters that the film could draw from.

One particular character from the comics is more important to the original stories than any of the Avengers, and this character is Adam Warlock. However, Warlock was ruled out by James Gunn.

So, aside from Warlock, let's have a look at the 15 New Characters Who Need To Be In Avengers: Infinity War.

15. Mistress Death

In the post-credits scene for The Avengers, an alien remarked that to face Thanos would be "courting death itself," prompting Thanos to smile. The line was a reference to the personification of death and the object of Thanos' affection: Mistress Death.

Mistress Death is a cosmic entity with the power over life and death. Thanos, a nihilist, has always been obsessed with death. His greatest desire is to win the heart of Mistress Death, who generally gives him the silent treatment and refuses to return his advances.

When Thanos achieved omnipotence by assembling the Infinity Gauntlet, Thanos wiped out half of the universe to please Mistress Death, and gave Earth's heroes a fighting chance just to impress her. Kevin Feige says that Thanos' motivation in Avengers: Infinity War is similar to the character's motivation in Infinity Gauntlet, which suggests that Mistress Death could have a role in the film.

14. Black Order

The Black Order

Rumors have suggested that a group of cosmic villains called the Black Order will be appearing in Avengers: Infinity War. The Black Order are relatively new characters who were introduced in the pages of The New Avengers in 2013 as a team of evil alien warriors working for Thanos.

The group is composed of Corvus Glaive, Proxima Midnight, Ebony Maw, Supergiant, and Black Dwarf. The Black Order raids planets at the behest of Thanos, and have also hunted down the Infinity Gems.

Set pictures indicate that at least one member-- Corvus Glaive-- will be in the movie. Another rumor suggests that the Black Order will be portrayed as Thanos' adopted children, meaning that Gamora and Nebula could be former members of the group.

13. Moondragon

Moondragon from the Guardians of the Galaxy

In Guardians of the Galaxy, Drax mentioned that his daughter, Kamaria, was murdered by Ronan the Accuser. "Kamaria" has Swahili origins and means "moonlight." The name is a reference to the Moondragon, the comic book of version of Drax's daughter.

In the comics, Drax was actually a human who was murdered by Thanos and had his consciousness placed in the body of a monster. His daughter, Heather Douglas, was thought to be dead as well, until it was discovered that she was taken to Titan by Mentor and raised to become an expert in martial arts and a powerful telepath. As "Moondragon," she left Titan and came to Earth to find a way to defeat Thanos.

Could the link between the Guardians of the Galaxy and Earth in Avengers: Infinity War be Moondragon? Though Drax's origins have clearly been rewritten for the movies, it wouldn't be impossible for Moondragon to exist in the MCU even if Drax's daughter isn't human. It could be revealed that, like Moondragon, Kamaria somehow survived the attack and was secretly rescued by an enemy of Thanos.

12. Elders of the Universe

The Elders Of The Universe And Their Pursuits

Though details of the plot for Avengers: Infinity War are sparse, what we do know is that it will involve Thanos and his plans for the six Infinity Stones. This idea resembles the comic book event, Infinity Gauntlet.

In this story, Thanos had to track down all six of the Infinity Gems. Each one was in the possession of an Elder of the Universe. The Elders are the last living members of ancient alien races, and each one has some kind of hobby or special power that they're known for. One by one, Thanos had to find and defeat the Collector, the Grandmaster, the Runner, the Champion of the Universe, the Gardener, and the In-Betweener.

Collector and Grandmaster will both be in the MCU by the time Avengers: Infinity War releases. Like his comic book counterpart, Collector already possesses one of the Stones. Only the Reality Stone has yet to be introduced, though its location is expected to be revealed soon. Will it be in the possession of the Grandmaster in Thor: Ragnarok? At least one Elder (the Collector) has been confirmed to appear in Avengers: Infinity War. Will he be joined by some of his fellow Elders?

11. Quasar

Quasar leads the West Coast Avengers into battle in Marvel Comics.

Wendell Vaughn was a S.H.I.E.L.D. agent-in-training who was told he lacked the fighting edge needed to serve in the field. Plagued with self-doubts, Vaughn's life was turned upside down when he put on the Quantum Bands that belonged to the 1950s superhero Marvel Boy.

Vaughn was made Protector of the Universe by the cosmic being Eon, and was chosen to fill the extremely large shoes of the previous Protector of the Universe Captain Mar-Vell. Taking the name "Quasar," Vaughn felt out of his element for years due to being thrust into a world full of superheroes like the Avengers, the Fantastic Four, and the Hulk. Vaughn felt outclassed by his peers, but found a way to become the hero the universe needed.

During Infinity War, Thanos asked Quasar to sacrifice himself to stop the Magus by using the Ultimate Nullifier to erase him from existence. However, the plan failed and unfortunately, Quasar died for nothing. It turned out to be a ruse by Thanos to have Quasar killed. Luckily, Quasar was resurrected soon after.

10. Agatha Harkness

Scarlet Witch talks with the ghost of Agatha Harkness in Marvel Comics.

Doctor Strange is the Sorcerer Supreme, but he's not the only Marvel hero capable of wielding powerful magic. Though known for her hex powers, Scarlet Witch can also cast "chaos magic." Her chaos magic has made a tremendous impact on the Marvel Universe, with its instrumental role in events like Avengers Disassembled, AXIS, Avengers vs. X-Men, and House of M.

It was Agatha Harkness who taught Scarlet Witch how to use this power. Harkness was an ornery, yet wise old woman who had previously worked as a nanny to Franklin Richards. She came to live at the Avengers Mansion to serve as a tutor for Scarlet Witch.

During their lessons, Harkness kept Scarlet Witch isolated from the other Avengers so that the two could practice in private. Soon, Scarlet Witch grew into powerful sorceress. In dire situations like Infinity War, Scarlet Witch would consult Harkness' magical expertise.

With Doctor Strange bringing magic to Avengers: Infinity War, Scarlet Witch could begin to explore her magical potential, which would also open the door for an appearance from Agatha Harkness.

9. Pip the Troll

Peter Dinklage will be appearing in Avengers: Infinity War, yet the identity of his character has yet to be revealed. Fans are speculating that Dinklage's character is Pip the Troll, Adam Warlock's sidekick and a member of the Infinity Watch. Despite having no super powers of his own, the cigar-smoking, ne'er-do-well troll has been fighting Thanos since the 1970s.

Pip first appeared in comic books when he encountered Adam Warlock on an alien planet. The two became involved in a struggle with the Magus, which soon lead to a team-up with Thanos. Pip was later killed by Thanos and resurrected years later by Warlock.

Pip had key roles in Infinity Gauntlet, Infinity War, and Infinity Crusade as the protector of the Space Gem. With the Space Gem, Pip the Troll could go anywhere he wanted in the universe.

8. The Living Tribunal

Often thought of as the supreme being of the Marvel Universe, the Living Tribunal is the all-powerful entity that stands as a judge to all cosmic entities, including Eternity, Galactus, the Watchers, and the Celestials.

While most cosmic entities dwell within their own universes, the Living Tribunal safeguards them all-- meaning that only one Living Tribunal exists across all alternate universes. When the universe is in danger, it is the Living Tribunal-- the Keeper of the Cosmic Balance-- who decides what course of action to take, or if any action should be taken at all.

When Thanos assembled the Infinity Gauntlet and destroyed half of the universe, the Living Tribunal ruled that no action against Thanos was necessary. When Warlock wore the Gauntlet, the Tribunal ruled that Warlock was not allowed to use the full power of the Infinity Gems and that the Gems could never again be used together. This decision is what led Warlock to create the Infinity Watch, a group dedicated to protecting the Infinity Gems.

7. Eon

Described as "He Who Waits," the cosmic entity known as Eon is the offspring of Eternity, the personification of the universe's lifeforce. Eon's role in the universe is to safeguard life itself. Eon must appoint Protectors of the Universe to ensure that the world is defended from cosmic threats like Thanos.

Eon has been selecting Protectors of the Universe for thousands of years. To help them in their cosmic duties, Eon gives his chosen Protector a pair of golden bracelets called the Quantum Bands. The Protector is also endowed with cosmic awareness, an ability that allows them to detect disturbances in the universe.

Eon guided both Captain Mar-Vell and Quasar in their roles as Protectors, but sometimes overstepped his boundaries when making sure that they remained devoted to their cause. On one occasion, Eon reanimated Quasar's father, who had died of a heart condition, because he believed that if Quasar knew his father was dead, his grief would become a distraction.

As a character with strong ties to cosmic events in the Marvel Universe, Eon could easily play a big part in Avengers: Infinity War, and could even have an expanded role in Captain Marvel.

6. Captain Mar-Vell

Some of Thanos' most famous battles have been with the Avengers, the Guardians of the Galaxy, and Adam Warlock, but the Mad Titan's original archenemy was the first Captain Marvel, Mar-Vell. Mar-Vell was a pink-skinned Kree warrior who betrayed his people and became a hero of Earth. In the 1970s, it was he who led the Avengers against Thanos during "The Thanos War."

He's also the man who so many other heroes have tried to honor by taking his name-- the latest of which being Carol Danvers, who will carry the title of "Captain Marvel" in the MCU film of the same name. Danvers got her powers from Mar-Vell via a blood transfusion.

If her comic book origin carries over into the film, Mar-Vell will soon need an introduction into the MCU. Giving Mar-Vell a post-credits scene or even a cameo to acknowledge his relationship with Thanos would be a great way to set up Captain Marvel.

5. Starfox

According to Kevin Feige, the real star of Avengers: Infinity War is Thanos. With Thanos getting such an important role in the film, it's hard to imagine that any backstory or flashbacks for the character won't feature his brother, Eros.

Known in the superhero world as "Starfox," Eros has the power to mentally influence the pleasure center of the brain. As an Eternal, Eros has all the abilities typical of his species: super strength, immortality, flight, and the power to manipulate matter.

Eros is also a lifelong womanizer with a carefree attitude. With the appearance of a human, Eros bears no resemblance to his brother, though they both share the same parents. Eros has opposed Thanos in many of his various attempts at conquest, and even served as a member of the Avengers for a short time in the 1980s.

4. Mentor

A movie about Thanos is sure to show us what makes the Mad Titan tick. If the movie dives into his comic book origin story, it's a good bet that we'll meet Mentor, Thanos' father.

Mentor is an Eternal scientist from Earth who founded a colony on Titan, one of Saturn's moons. Mentor and his wife, Sui-San, had two children: Thanos and Starfox. While still a child, Thanos developed an obsession with death that troubled his parents.

As he grew older, he became more ambitious and attempted to conquer Titan. His efforts caused the death of his mother. Mentor and his father, Chronos, worked together to create Drax the Destroyer-- an alien monster with the soul of a human. Drax's purpose was to kill Thanos.

Mentor holds no love in his heart for his son, and later regretted not killing Thanos when he was still in his crib.

3. U.S. Agent

At the end of Captain America: Civil War, Steve Rogers made the decision to give up the shield. It's been confirmed that he's also shed the mantle of Captain America. This leads us to ask: who will be Captain America now?

Some fans think it will be Winter Soldier, who also took up the shield in the comics. However, since Winter Soldier is currently in suspended animation in Wakanda, it would make sense if the government were to select the next Sentinel of Liberty.

A possible candidate can be found in the comics. In the 1980s, superhuman soldier John Walker became the new Captain America following Rogers' decision to resign. Later, Rogers, calling himself "The Captain," decided that Walker's violent behavior had tarnished his legacy and returned to take his shield back.

The story concluded with a dramatic showdown. After Rogers defeated Walker, Walker took the name "U.S. Agent" and became a member of the West Coast Avengers with Rogers' "Captain" costume and a replica of Captain America's shield.

Far from a Captain America clone, U.S. Agent has become a recurring character in various Captain America and Avengers titles, usually serving as a foil to protagonists like Cap, Hawkeye, and, most recently, Sam Wilson.

2. Henry Peter Gyrich

During the '70s, the Avengers faced a new kind of problem when their priority status was taken away by the government on the word of Henry Peter Gyrich from the National Security Agency. Without support from the government, the Avengers couldn't use Quinjets or their high-tech computers.

Gyrich was appointed the U.S. Government Liaison to the Avengers, giving him the power to institute various rules and restrictions on the Avengers. This was a new era for the team, as it was the first time that the government began telling the Avengers how to run their team. Gyrich limited the team to seven members, and even forced them to include minorities.

The signing of the Sokovia Accords in Captain America: Civil War will bring a new level of government supervision to the Avengers, and we could see that take shape in Avengers: Infinity War. When that happens, don't be surprised if this movie introduces Henry Peter Gyrich to the MCU.

1. Magus

Magus uses the Infinity Gauntlet in Marvel Comics.

Thanos may be the antagonist of Avengers: Infinity War, but, in the comic book event, Thanos was actually an ally to Earth's heroes. It turned out that there was a threat worse than Thanos: the Magus.

There have been different incarnations of the Magus, with each one being an evil version of Adam Warlock. In his earliest appearances, he was a future version of Warlock who was corrupted by the hero's use of the Soul Gem. Warlock had to go forward in time to commit "cosmic suicide," thus erasing the Magus' timeline.

The version of the Magus that appeared in Infinity War was the product of Warlock's actions in Infinity Gauntlet. When Adam Warlock gained omnipotence by putting on the Gauntlet, he purged himself of his good and evil sides in order to make a purely logical decision. The evil portion of his soul created the Magus, who gathered together five Cosmic Cubes to conquer the world.

We know that Adam Warlock won't be in Avengers: Infinity War, but a role in Avengers 4 hasn't been ruled out. If the future Magus shows up for a post-credits scene, it would make sense for him to appear prior to Warlock's entry into the MCU.
