Pom Klementieff Teases Avengers: Doomsday Return With Mantis Post

Actor Pom Klementieff has reignited hopes for a Guardians of the Galaxy return after sharing a social media photo alluding to the upcoming Marvel Cinematic Universe crossover event. The image, featuring a mantis on slide 12 of an Instagram carousel, coincides with the anticipated U.S. release date of Avengers: Doomsday in 2026 and suggests Klementieff may be teasing her character's return as Mantis. This speculation arises despite Vol. 3 serving as a bittersweet finale for the team led by James Gunn, where core members like Peter Quill returned to Earth while others departed or rebuilt communities on Knowhere. Although Klementieff was not included in the official cast announcement for Avengers: Doomsday, which focuses heavily on returning Avengers and new characters including Doctor Doom, her recent post has sparked intense fan theories about a potential appearance. Meanwhile, former Guardians actor Amanda Seyfried confirmed she turned down Gamora's role to prioritize family life over stunts and makeup trailers, while critics rank Mantis as the least likely Guardian to survive an apocalyptic Marvel Zombies scenario due to her reliance on physical proximity for emotional influence.
