We're Eternals. We came here seven thousand years ago, to protect humans from the Deviants.
~ Sersi
This planet's my home, but I can't pretend to be human anymore.
~ Sersi to Dane Whitman.

Sersi is the main protagonist of the 2021 Marvel Cinematic Universe film Eternals.

She is a member of the community genetically-engineered Eternals on Earth who relishes in moving amongst the Humans, and is devoted to protecting mankind from the Deviants. She also works as a museum curator, the ex-wife of Ikaris, and is in a relationship with the historian Dane Whitman.

Sersi is portrayed by Gemma Chan, who also portrays Astrid Leong-Teo in Crazy Rich Asians and Minn-Erva in Captain Marvel and voices Namaari in Raya and the Last Dragon.



Sersi, along with the rest of the Eternals, was created by Arishem the Judge for the sake of getting rid of the Deviants. 7,000 years ago, she was sent to live on Earth, where she would protect humanity from the Deviants. More so then many of the other Eternals, she would come to love humanity and would often go the extra mile to help them in many of their day-to-day tasks. She was also in a relationship with Ikaris for a while after the latter finally confessed his feelings for her with some encouragement from Ajak.

However, when Ikaris came to learn that the Eternals' true purpose was to help humanity's population grow until it was suitable for a Celestial that was planted inside the earth to hatch, but at the expense of destroying the planet, he left her since he knew she, in particular, wouldn't be able to handle the truth due to her affection for the people of the planet. Later on when the Eternals went their separate ways, she would live a humble life in London with both her human boyfriend Dane and fellow Eternal Sprite where she worked as a museum curator.


While speaking to Sprite about her relationship with Dane, the two were attacked by Deviant until Ikaris arrived, and was forced to reveal the truth to Dane about her origin. Leaving Dane in England, Sersi traveled to South Dakota to speak with Ajak, but the group found her buried corpse. The communication sphere then went into Sersi, with Ajak giving her the role of becoming the Eternals' new leader. The group then decided to find the others so they could fight against the Deviants, and first traveled to Mumbai to find Kingo. After convincing him to join after telling of Ajak's death, the group traveled to Australia to find Thena and Gilgamesh, as Thena was in exile for suffering from Mahd Wy'ry. Gilgamesh would advise Sersi to relax and listen so she could use the communication sphere, and met with Arishem, who revealed their true mission was to start the emergence to awake Tiamut the Communicator.

She then informed the others of the truth, and offered that they prevent the emergence to save humanity, and Gilgamesh advised they could put Tiamut to sleep. The Eternals then traveled to the Amazon Rainforest to meet with Druig, who refused to join them as he was leading his own community of people. The compound was attacked by Kro and the Deviants, which resulted in the death of Gilgamesh and Kro revealing that he knows the truth himself after taking Ajak's power. Druig decided to join them after Gilgamesh's funeral, but explained that he didn't have the power to put a Celestial in a sedative state. The Eternals then traveled to Chicago to meet with Phastos, whom had started his own family despite stating he gave up on humanity after the bombing of Hiroshima.

Phastos was convinced by his husband to join the group for the sake of their son, and the Eternals traveled to Iraq to locate the Domo. Finding their ship, the group reunited with Makkari, and explained to her the situation that was at hand. While Phastos worked on creating a device so they could form the Uni-Mind, Ikaris destroyed his plans, leading to Sersi and Druig to come to the realization that Ikaris knew about the emergence. He explained that he indirectly caused Ajak's death when she wanted to avert the emergence, and that he is loyal to the Celestials. Sersi and the others battled him and Sprite, with the latter siding with Ikaris since she believed the emergence would allow her to grow into an adult. Sersi was able to form the Uni-Mind when Ikaris and Sprite decided to assist the Eternals, leading to her killing Tiamut and preventing the emergence.

Sersi witnessed Ikaris apologize and fly into the sun to his presumed demise, and was able to turn Sprite into a human due to still having a link. After stopping the emergence, Sersi returned to London as Druig, Thena and Makkari decided to leave Earth to find other Eternals and thell them the truth. While speaking with Whitman, Sersi was taken by Arishem, who was angered that the Eternals sabotaged the emergence. The Celestial decided to spare humanity if he could look into the memories of Sersi, Phastos and Kingo, as judgment.


Sersi had a great love for humans so she often used her transmutation powers to protect them and help them advance. She took the time to mingle with them and understand their ways. She had a positive and highly sympathetic demeanor, though she tended to be low-key in her interactions with others.

Sersi had been in love with Ikaris for millennia. Their relationship ended when the Eternals developed conflicting ideals and went their separate ways, but nevertheless she helped him reunite the group for one last mission. She was on friendly terms with the rest of the Eternals, and held no grudges even against Sprite who coveted her ex-husband as she understood her resentments.

In the present day, Sersi became addicted to smartphones and would often be seen fidgeting with the gadget.

Powers and Abilities

    • Superhuman Strength: Like all Eternals, Sersi possesses great superhuman strength, numerous times stronger than any normal human being.
    • Superhuman Durability: Sersi's body is numerous times more resistant to physical and energy damage than any normal human being. During the battle in the Amazon Rainforest, Sersi was unharmed and experiences no injuries after being knocked aside by the tail of a large Deviant, which sends her flying into a wooden building which is destroyed in the process. She was also stabbed through the stomach with a knife bySprite in an attempt to stop Sersi from ending the Emergence. Whilst this does initially disable Sersi, she appears to have suffered no repercussions from this injure and she soon joined the Uni-Mind.
    • Superhuman Speed: Sersi can run and move at great superhuman speed, much faster than any normal human being.
    • Superhuman Agility: Sersi naturally possesses far greater agility, equilibrium, flexibility, dexterity, balance, and body coordination than any normal human being. In an attempt to lure a Deviant away from Sprite and Dane Whitman, she jumped over a fence and scaled a wall with relative ease.
    • Superhuman Stamina: Sersi's advanced musculature is considerably more efficient than any normal human being. As a result, her muscles virtually do not produce fatigue toxins during physical activity. Her endurance allows her to exercise her maximum capacity for an extremely long period of time without tiring at all. This is shown during the emergence when Sersi runs for miles towards the active volcano, with lava around her, without any sign of exhaustion from the immense heat around her.
    • Superhuman Reflexes: Sersi can react and dodge objects traveling at high speeds, much quicker than any normal human being.
    • Regenerative Healing Factor: Sersi's metabolism enables her to rapidly regenerate damaged bodily tissue with far greater speed and efficiency than any normal human being.

        • Matter Transmutation: Sersi wields the power of matter transmutation, changing the makeup of any non-sentient material she touches. Upon her arrival on Earth, Sersi transformed a rustic knife into a more ornamented one and turned the earth into water to irrigate the plantations in the mountains. Sersi transformed a shield-like artifact into sand to save one of her students. During the fight against Kro in London, Sersi transformed the ground into sand and then returned it to its original form to trap the Deviant and later transformed a bus into rose petals. In the ambush in the Amazon Rainforest, to help Druig fight a Deviant, Sersi transformed first a tree into water and then into ice, making it heavier and dropping it on top of the Deviant. In the same battle, Sersi also transformed a wooden cabin into steel to protect the civilians inside and even a Deviant into a tree, a feat that surprised all of her fellow Eternals,as Sersi was only supposed to be able to transmute non-sentient materials. During Tiamat the Communicator’s Emergence, Sersi transformed a volcanic rock into several birds that flew away, showing that she can manifest life from the lifeless and possibly vice-versa.
        • Former Powers
        • Celestial Communication: After becoming the new Prime Eternal, Sersi received the Celestial Communication Sphere from Ajak, allowing her to telepathically communicate directly with the Celestials, the architects of existence itself. However, she lost this power after Phastos extract the sphere from her to use it in the Uni-Mind’s bracelets.
      • Uni-Mind Energy Manipulation: After connecting with the cosmic energy and mind of the other Eternals, Sersi's powers was increased to the point she was able to transform Tiamat the Communicator’s, an all-powerful Celestial, into stone. Later, she also transformed Sprite into a normal human with the remaining Uni-Mind energy.
        • Levitation: While created the Uni-Mind, Sersi was levitate into the conjuntion sphere of all cosmic energy of her fellows Eternals and later landed into Tiamat the Communicator.
