Spoilers for Eternals. This guide identifies the main Eternals, explains their powers and limits, maps their relationships, and provides a quick checklist for rewatches, watch parties, and MCU lore discussions. Because the film presents the team through different eras and perspectives, the clearest way to understand them is to separate what each character can do from how each character chooses to use that ability.
Overview
The Eternals are a group of powerful beings sent to Earth by the Celestial Arishem to protect developing human civilizations from Deviants. In the film, they are not simply a conventional superhero team. Their mission, memories, loyalties, and understanding of Earth change over thousands of years. That history explains why the group is often divided even when its members share the same origin.
Their abilities are distinct, but they are connected by a common limitation: each Eternal is expected to serve a larger cosmic purpose. The film also shows that their powers are not a complete measure of their importance. Sersi’s judgment, Phastos’s engineering, Druig’s ethics, and Thena’s memories all shape the story as much as their combat skills do.
| Character | Actor | Primary ability | Relationships and limits | Key film reference and comic note |
|---|---|---|---|---|
| Sersi | Gemma Chan | Transforms matter by touch | Former partner of Ikaris; later connected with Dane Whitman. Her power requires judgment and proximity rather than simple force. | Her transformation of the Deviant leader and her role in stopping the Emergence are central. She is adapted from the Marvel Comics character of the same name. |
| Ikaris | Richard Madden | Flight and energy beams from his eyes | Formerly married to Sersi; loyal to Arishem’s mission. His emotional conflict becomes a major weakness. | His flight and final confrontation with Sersi define his arc. He is based on the comic character Ikaris, though the MCU version has a different characterization. |
| Kingo | Kumail Nanjiani | Projects energy blasts from his hands and fingers | Maintains a close relationship with his valet, Karun. He leaves the final battle because he cannot betray Ikaris. | His Bollywood career and family identity provide a modern contrast to the team’s ancient history. His name comes from the comics, where the character has a different presentation. |
| Sprite | Lia McHugh | Creates realistic illusions | Appears physically young despite her immense age. Her unchanging body leaves her feeling isolated from humanity. | Her illusion of the Domo crew helps the team escape danger. The MCU version reworks the comic character’s presentation and gender. |
| Phastos | Brian Tyree Henry | Designs and manipulates advanced technology | His faith in humanity is damaged by war, but his family helps restore his sense of purpose. | His inventions influence human technological progress, including weapons. He is adapted from the comics’ Phastos and is presented in the film as an openly gay Eternal. |
| Makkari | Lauren Ridloff | Super-speed | Shares a close bond with Druig. Her speed is most effective when paired with timing, terrain, and surprise. | Her arrival at the Domo and battle with Ikaris showcase her movement. The film version changes several details from the comic counterpart, including gender and identity. |
| Druig | Barry Keoghan | Controls minds | Questions the team’s noninterference rule. His relationship with Makkari is important, while his methods create tension with the others. | He protects a community in the Amazon by controlling threats. The MCU character draws from the comic Druig but is substantially reinterpreted. |
| Thena | Angelina Jolie | Creates weapons from cosmic energy | Suffers from episodes associated with her memories and relies on Gilgamesh for support and protection. | Her fights with Deviants demonstrate precision and adaptability. She is based on the comic character Thena, whose mythology and history differ from the film’s version. |
| Gilgamesh | Ma Dong-seok | Forms powerful energy-enhanced fists | Acts as Thena’s protector and closest companion. His physical strength does not make him immune to sacrifice. | His defense of Thena during her episodes and his fight with Kro are key scenes. The film combines the character with elements associated with other powerful Eternals in the comics. |
| Ajak | Salma Hayek | Heals others through cosmic energy | Leads the group and understands more about the Celestials’ plan than most of the team. | Her death exposes the Deviants’ evolution and forces the Eternals back together. The MCU version differs notably from the traditional comic portrayal. |

Checklist by scenario
Before a first viewing
- Remember that the characters have lived on Earth for thousands of years, but they do not all share the same view of humanity.
- Track the two central threats separately: the Deviants are a direct physical danger, while the Emergence creates a moral and cosmic crisis.
- Watch for the distinction between an ability and a role. Ajak leads, Phastos builds, Sersi transforms, and Druig challenges the team’s rules.
Before a rewatch or recap
- Follow Sersi and Ikaris as a relationship arc, not only as a power comparison. Their disagreement over the Emergence drives the ending.
- Pair Thena with Gilgamesh when reviewing character development. Their bond explains why the Deviant attack is emotionally significant.
- Compare Druig’s decision to protect humans with Phastos’s loss of faith after witnessing war. Both characters respond to human violence in different ways.
- Notice how Sprite’s illusions, Makkari’s speed, Kingo’s energy blasts, and Phastos’s technology support different kinds of action scenes.
For a watch party or trivia session
- Ask participants to match each Eternal to a power, a relationship, and a defining choice.
- Use the quick formula “ability, limitation, decision.” For example: Sersi transforms matter, needs contact, and ultimately chooses Earth over the original mission.
- Separate film canon from comics history. A shared name does not mean the MCU character has the same origin, identity, or role as the comic version.
For timeline and ending discussions
- Place the team’s historical flashbacks alongside the present-day reunion rather than treating them as separate origin stories.
- Remember that Ikaris’s strength does not resolve his conflict with Arishem’s plan.
- Review the final positions of the team before discussing a possible sequel or future appearance. The film leaves several characters in different locations and circumstances.
What to double-check
Power limits: The film demonstrates what characters can do, but it does not provide a complete technical rulebook for every ability. Avoid presenting speculative limits as confirmed canon. It is safer to describe an ability through its on-screen examples: Sersi changes matter, Druig influences minds, and Phastos manipulates or assembles technology.
Character relationships: Sersi and Ikaris were married, but their conflict is not only romantic. It reflects opposing beliefs about duty and humanity. Druig and Makkari share a connection, while Thena and Gilgamesh have one of the film’s strongest bonds. Kingo’s loyalty to Ikaris is also important, even though he does not join the final confrontation.
Comic comparisons: The Eternals movie adapts names and broad concepts from Marvel Comics but changes characterization, history, relationships, and representation. Use “comic counterpart” to indicate a source connection, not a claim that the two versions are identical.
Survival and status: Do not assume that a character’s absence from one scene means the character is dead, or that an unresolved ending confirms a future appearance. For later status discussions, consult the dedicated guide to what happened to the Eternals after the movie and separate confirmed story information from theory.
Common mistakes
- Calling every Eternal a fighter. Some are strongest when supporting, creating, healing, or making strategic decisions rather than trading punches.
- Ranking powers without context. Flight, speed, energy projection, mind control, and matter transformation solve different problems. The setting and objective matter more than a simple strongest-to-weakest list.
- Confusing Deviants with Eternals. Deviants are connected to the Celestials’ experiments but are a separate group with different characteristics and goals.
- Ignoring emotional weaknesses. Ikaris’s loyalty, Sprite’s frustration, Thena’s memory problems, Phastos’s grief, and Druig’s anger all affect how the team performs.
- Treating the film as a complete explanation of the comics. The movie is its own continuity within the MCU. Comic references are most useful when they clarify inspiration, not when they override the film.
- Forgetting the post-credit material. The credits scenes introduce additional questions about the wider cosmic story. Read an ending and credits-scene explanation separately if you want a full spoiler discussion.
When to revisit this guide
Return to this Eternals characters guide before a rewatch, a Marvel movie-order marathon, a fan discussion, or a watch party. It is also worth checking whenever Marvel confirms a new appearance, adds casting information, develops a character in another project, or clarifies MCU continuity. Those updates may change a character’s status or future relevance without changing the abilities shown in the original film.
For a practical refresh, start with the table, then choose one scenario checklist. If you are discussing the ending, review the film’s final choices and credits scenes. If you are comparing heroes, compare ability, limitation, relationship, and decision rather than relying on a power ranking. For viewing context, use the MCU timeline guide; for access details, check the current where-to-watch checklist. That simple routine keeps character facts, story interpretation, and later MCU developments clearly separated.
