Which Actors Joined the Cast in Guardians of the Galaxy Vol. 2?
The 2017 sequel expanded the ensemble with several new characters while retaining the original core.
Pom Klementieff as Mantis
Klementieff joined the franchise as Mantis, an empath with green-toned skin and insect-like antennae. She becomes a key member of the team and a frequent source of comic relief. Her performance is based on the Marvel Comics character of the same name.
Kurt Russell as Ego the Living Planet
Russell portrays Ego, a Celestial who is also Peter Quill’s father. The character is a living planet capable of projecting a human form. Russell’s casting was a significant addition for Vol. 2, providing a major antagonist with a personal connection to the lead.
Returning cast and cameos (Yondu, Nebula)
Michael Rooker returns as Yondu Udonta, whose role expands considerably. Karen Gillan’s Nebula also appears, continuing her arc from the first film. The film also features a range of voice cameos, including David Hasselhoff as himself, Miley Cyrus as Mainframe, and Sylvester Stallone as Stakar Ogord.
Sylvester Stallone’s appearance as Stakar Ogord is a brief but significant cameo linking to the original Guardians of the Galaxy comics. The character is a founding member of the team in the source material.
What Is the Cast of Guardians of the Galaxy Vol. 3?
The 2023 installment concluded the trilogy and introduced new characters while bringing back nearly the entire original cast.
Will Poulter as Adam Warlock
Poulter plays Adam Warlock, an artificial being created by the Sovereign. The character has a golden appearance and serves as a complex figure in the narrative. Poulter’s portrayal marks a major expansion of the MCU’s cosmic roster.
Returning Guardians (Pratt, Saldaña, Bautista, Diesel, Cooper, Klementieff)
Chris Pratt, Zoe Saldaña, Dave Bautista, Vin Diesel, Bradley Cooper, and Pom Klementieff all return. Saldaña’s Gamora appears as a variant from an alternate timeline, following the character’s death in Avengers: Infinity War. This marks Bautista’s final appearance as Drax the Destroyer.
New additions and cameos
Chukwudi Iwuji joins as the High Evolutionary, the primary antagonist. Maria Bakalova voices Cosmo the Spacedog, a telepathic canine. Linda Cardellini voices Lylla, an otter-like test subject. The film also features cameos from Michael Rosenbaum as The Grandmaster and James Gunn as a voice in Rocket’s hallucination.
Who Are the Supporting Villains and Allies in Guardians of the Galaxy?
Several antagonists and allies appear across the trilogy, some solely in the first film and others as recurring presences.
Lee Pace as Ronan the Accuser
Pace plays Ronan, a Kree extremist who serves as the primary antagonist of the first film. His character features blue face paint and armor, distinguishing him visually. Ronan seeks to destroy Xandar using the Power Stone.
Josh Brolin as Thanos
Brolin appears via voice and performance capture as Thanos, the Mad Titan. In Vol. 1, he appears in an uncredited cameo. He returns for a post-credits scene in Vol. 2. His presence links the Guardians films to the larger MCU Infinity Saga.
Michael Rooker as Yondu Udonta
Yondu is a blue-skinned Ravager leader and a father figure to Peter Quill. Rooker’s character evolves from an antagonist in Vol. 1 to a redeemed hero in Vol. 2. His death in the sequel is a key emotional moment.
Karen Gillan as Nebula
Gillan portrays Nebula, the cyborg daughter of Thanos. Initially an antagonist in Vol. 1, she gradually becomes an ally. Her role expands significantly in the sequels, leading to a prominent position in Vol. 3.
Nebula is not a villain in the traditional sense after Vol. 1. Her arc shifts from antagonist to ally across the trilogy, making her a complex supporting character rather than a straightforward antagonist.
Who Are the Green and Blue Characters in Guardians of the Galaxy?
Viewers often identify characters by their skin color. Two green-skinned and two blue-skinned characters appear prominently.
Gamora: the green-skinned assassin
Zoe Saldaña’s Gamora has bright green skin and is a member of the original team. She is the adoptive daughter of Thanos and a highly skilled fighter.
Mantis: the green-skinned empath
Pom Klementieff’s Mantis also has green-toned skin, though it is lighter than Gamora’s. She has antennae on her forehead and uses empathic powers. Both characters are frequently confused due to their similar skin color.
Yondu: the blue-skinned Ravager
Michael Rooker’s Yondu has bright blue skin. He is the most commonly referenced ‘blue guy’ from the franchise due to his distinctive appearance and significant screen time.
Ronan: the blue-faced Kree radical
Lee Pace’s Ronan wears blue face paint as part of his Kree heritage. This makes him a secondary blue-character candidate. His skin is otherwise normal human tone under the paint.

Why Does the Guardians of the Galaxy Cast Include Both Live-Action and Voice Actors?
The franchise blends live-action performances with CGI characters that require voice work. Chris Pratt, Zoe Saldaña, Dave Bautista, and Pom Klementieff perform in physical costume or makeup. Bradley Cooper provides the voice for Rocket Raccoon, while Vin Diesel voices Groot. Sean Gunn serves as the on-set stand-in for Rocket, providing movement reference for animators. This combination allows for characters that are visually created through digital effects while still being anchored by actor performances. The approach is consistent across all three films, with the same voice actors retained throughout. The use of voice actors for key characters is a hallmark of the series and contributes to its unique identity within the MCU.
