For an unseemingly important character, Mantis was handed a large amount of screen time throughout three movies. Pom Klementieff introduced the character in Guardians of the Galaxy Vol. 2. She became an important member of the team. In the climax of the movie, she used her empathetic powers to take down Ego. Then she rolled over with the team to meet the Avengers in Infinity War and Endgame. But keep in mind, she actually became an Avenger in the comics. While she served an important role in Guardians Vol. 2, a fan pointed out her importance in the final Avengers: Endgame battle.
User, u/clubpenguin2005, posted a clip to the r/Avengers subreddit community. Amongst the several other heroes fighting Thanos’s forces, you can see Mantis. See how she uses her powers to put the gorilla-sized Outrider to sleep.
I used to think she was useless until I looked closely lol she sleeps enemies

Klementieff spoke to Paper Magazine about her joy in portraying the character.
“It’s so fun. She’s weird, she’s special, she’s in her own world and I get to do funny things and I love to do that. Oftentimes in movies like this, the guys get to do the funny things and the girls have to play the ‘stop having fun guys’ role, which is great, too, but it’s nice to have a different kind of woman. It’s fun to play that. I like to be the weirdo. People sometimes come up to me and tell me how much they love the character and feel a connection with Mantis because they themselves are not that confident or don’t feel good in their own skin. For me, it’s really touching and important that this character exists. I think Mantis’ [story] arc inside the movie is really interesting, too, because she doesn’t know how powerful she is. She was raised in a way that she was never told that she was strong and she was living in a very meek kind of way and then meeting the Guardians opened a new world to her.”
I’m sure the next time we’ll see Klementieff’s Mantis will be in Guardians of the Galaxy Vol. 3. There’s no release date for the film yet. But chances are, it will be sometime between 2022 and 2023. Stay tuned to Screen Geek for confirmation on that release date, and everything else in the MCU. In the meantime, you can pick out all the different tactics for each hero in that battle for yourself. As Avengers: Endgame is on Digital and Blu-Ray now.
