Warning! Spoilers for Eternals #5 by Marvel Comics
With a traitor on the loose among the Eternals, Sersi just embarrassed Tony Stark in order to gain key information about finding the potential suspect who's working alongside Thanos. In Eternals #5, Sersi tricked Tony Stark into having drinks so she could shut down his nervous system in order to spring the Forgotten One, who was tracking her. All-in-all, it was quite a cunning move.
Sersi is one of the main members of the Eternals, a million-year-old race who rank as some of the most powerful cosmic heroes in the Marvel Universe. Sersi has multiple amazing powers, including the ability to cast illusions and use telepathy, as she's able to implant memories into the minds of other people. Sersi is set to debut as the main character in the upcoming Eternals film by Chloe Zhao, where she'll be played by Gemma Chan. Before appearing in the Marvel Cinematic Universe, Sersi is currently trying to crack the case of a traitor among the Eternals in the comics, who has helped Thanos return and shut down their resurrection machine. Her search for answers leads her former partner, Tony Stark.
In Eternals #5 by Kieron Gillen, Esad Ribic, Matthew Wilson, and VC's Clayton Cowles, the comic opens in New York, as Sersi enjoys drinks with Tony Stark. Suddenly, she begins to tell him she's been feeding him fake data in her quest to keep the Great Machine destroyed and locks down his nervous system. She reveals Thanos is behind the damage of the machine and that he will rule the Earth when she's done.
Sersi's evil turn is all an elaborate ruse to lure the Forgotten One who had been dodging the Eternals as he traveled across the sub-dimensional lair. He appears after hearing Sersi say she was working with Thanos and demands answers. Sersi, of course, just said she was responsible for the Great Machine's destruction to find the Forgotten One and the set-up works. Stark was just a pawn in the plan.
Returning to Stark, Sersi apologizes for the "Eternals business" and informs him they were trying to reveal the Forgotten One to question him about the destruction of the Great Machine. Tony is surprisingly forgiving, but Sersi isn't done messing with his mind. She wipes his mind of all mentions of Thanos to not draw the attention of the Avengers. Sersi leaves Tony, as Iron Man has no idea of what really just happened in front of him. At the moment, Sersi showed a small part of her incredible powers that helped find the Forgotten One. Unfortunately, Tony Stark's mind was played with to make it happen. Eternals #5 is in stores now.
