New concept art for "Guardians of the Galaxy Vol. 2" introduces the latest addition to the lineup: Marvel Comics character Mantis, played by Pom Klementieff.

She's depicted in this illustration by Andy Park -- "this image led us a lot as we were developing the film," director James Gunn explains -- alongside Drax, Groot, Yondu, Star-Lord, Rocket, Nebula. and Gamora.

"She has never really experienced social interaction," Executive Producer Jonathan Schwartz tells Entertainment Weekly. "Everything she learns about dealing with people, she learns from the Guardians of the Galaxy, which is a very weird group to learn your social intricacies from."

The art also shows Groot as we last saw him in 2014's "Guardians of the Galaxy," in baby form.

"He doesn't have the wisdom and experience of that Groot," Schwartz teases. "He's a younger Groot and a more rambunctious Groot. The question is, is he the same Groot, just smaller? Or is he a different Groot that's sprung up from the seed of the first Groot?"

He'll presumably have the same voice, however, as Gunn tagged Vin Diesel in his Facebook post.

Expect much more on Saturday, July 23, during the Marvel Studios panel at Comic-Con International. "I can't wait to show you guys more of what we have in store for you," Gunn writes.

Opening May 5, 2017, "Guardians of the Galaxy Vol. 2" stars Chris Pratt, Zoe Saldana, Dave Bautista, Vin Diesel, Bradley Cooper, Michael Rooker, Karen Gillan, Sean Gunn, Glenn Close, Pom Klementieff, Elizabeth Debicki, Chris Sullivan and Kurt Russell.
