Warning - the rest of this article contains spoilers for Guardians of the Galaxy Vol. 3

1. ) Peter Quill/Star-Lord - Chris Pratt

Chris Pratt as Peter Quill

Chris Pratt returns as Peter Quill in Guardians of the Galaxy Vol. 3. In the threequel, Peter did everything he could to save his best friend, Rocket, and rally the Guardians to ultimately defeat the High Evolutionary. 

Moreover, the movie's ending and post-credits scene also confirmed that the legendary Star-Lord will return for more adventures on Earth this time around. 

There's a strong chance that he will team up with the Avengers in his next adventure. Given that the status of Earth's Mightiest Heroes is unknown, the former Guardians leader could be what the team needs in order to make a triumphant return. 

2.) Gamora - Zoe Saldana

Although Gamora died in Avengers: Infinity War, Zoe Saldana is back as the ruthless warrior in Vol. 3 after Avengers: Endgame's time-travel shenanigans.

While the film revealed that Gamora was now the leader of the Ravagers, the former Guardian of the Galaxy still managed to rejoin Quill, Nebula, and the others for one final mission to save Rocket and ultimately defeat the High Evolutionary. 

At the end of the film, Gamora decided to stick with the Ravagers instead of rejoining the Guardians as a full-time member. Still, Gamora was able to have some type of closure with Peter before leaving. 

3.) Drax - Dave Bautista

Drax as Dave Bautista

Dave Bautista has been open about his Marvel retirement as Drax in the months leading to Guardians of the Galaxy Vol. 3, with him saying that the threequel is his "perfect exit."

Vol. 3 did manage to feature an incredible send-off to Drax, showcasing top-notch comedic timing with the character, heartfelt moments with the team, and a fitting ending where he served as a father figure for the children saved from the High Evolutionary. 

4.) Groot - Vin Diesel

Vin Diesel's Groot was stronger than ever in Guardians of the Galaxy Vol. 3, considering that the character is more muscular and "swole" in the threequel, as described by James Gunn. 

Throughout the movie, Groot took care of his best friend, Rocket while unleashing his new skill set to help the team take down the High Evolutionary.

At the end of Vol.3, Groot joined Rocket and the new iteration of Guardians to protect the galaxy from many threats. 

5.) Rocket - Bradley Cooper, Noa Raskin (Baby), Sean Gunn (Young)

Many would argue that Guardians of the Galaxy Vol. 3 is Rocket's movie, and this claim is quite fitting, especially after the character's origin story was pushed to the forefront.

Bradley Cooper returned with an incredible performance as Rocket, and he was not alone in that effort. Noa Raskin voiced Baby Rocket while Sean Gunn portrayed Young Rocket. 

In the film, Rocket finally defeated the High Evolutionary, successfully redeeming himself and finally avenging his friends who met their death at the villain's hands. In the end, Rocket became the captain of the new Guardians of the Galaxy, protecting the universe from different kinds of threats. 

6.) Nebula - Karen Gillan

From villain to hero, Karen Gillan's Nebula returned in Guardians of the Galaxy Vol. 3 as a full-fledged member of the team. 

The movie managed to establish how Nebula transformed from being a selfish villain to an important member of the team. More so, she was also able to adapt the Guardians' sense of humor, which is quite fitting.

In the end, Nebula decided to stay on Knowhere to lead the people to new adventures while also opening many opportunities for a future appearance down the line.

7.) Mantis - Pom Klementieff

Guardians of the Galaxy Vol. 3

Pom Klementieff's Mantis has been a notable member of the Guardians ever since her debut in Vol.2

After The Guardians of the Galaxy Holiday Special confirmed that she is Peter Quill's sister, the threequel showed more of her value in the team, such as surprisingly taking down foes at ease while also serving as the heart and voice of reason of the team.

However, in the movie's ending, Mantis left the team to seek out adventures on her own. It remains to be seen where Mantis could pop up next after finding her purpose, but a visit to Earth is possible since her brother is already there.

8.) Kraglin - Sean Gunn

Guardians of the Galaxy Vol. 3
Sean Gunn as Kraglin

After being used in minor roles in past MCU flicks, Guardians of the Galaxy Vol. 3 highlighted Kraglin's importance to the team like never before. 

Throughout the threequel, Kraglin struggled to control Yondu's arrow, but ultimately, he succeeded when his former captain reminded him to use his heart in doing so.

Given that Kraglin is an official Guardian of the Galaxy by the film's end, it looks like fans will see a lot more of Sean Gunn's notable MCU hero. 

9.)  Adam Warlock - Will Poulter

Guardians of the Galaxy Vol. 3

Will Poulter made his MCU debut in Guardians of the Galaxy Vol. 3 as Adam Warlock, the creation of the Sovereign as a means of revenge against the titular heroes. 

Although he was a villain at first, Vol. 3 redeemed Warlock at the end when the Guardians gave him a second chance and by saving Quill from his demise. Warlock ultimately became a member of Rocket's Guardians in the end. 

Vol. 3 director James Gunn already confirmed that Warlock could become a "really important" character in the MCU, indicating a number of exciting possibilities for the character's future. 

10.) The High Evolutionary - Chukwudi Iwuji

Chukwudi Iwuji made an emphatic MCU debut as the High Evolutionary in Vol. 3. Gunn said that the character is the franchise's "cruelest" villain yet, and it is backed up by the fans' hatred towards him. 

In fact, even his subordinates turned against him due to his obsession with capturing Rocket, thus further cementing why the High Evolutionary is pure evil. 

Guardians of the Galaxy Vol. 3 director James Gunn confirmed that a deleted scene confirming that the High Evolutionary is still alive is canon to the MCU, indicating that the villain could return at some point.

11.) Record Theel - Nico Santos

Nico Santos portrayed Record Theel, one of High Evolutionary's loyal followers. Record Theel was integral to Vol. 3's story, being the one that held the passcode to save Rocket's life. 

12.) Recorder Vim - Miriam Shor

Miriam Shor portrayed Recorder Vim, another loyal follower of the High Evolutionary. 

The character had a redemption arc in the end when she rallied the High Evolutionary's forces against him due to the villain's obsession to obtain Rocket.  

However, Recorder Vim met her demise when the psychotic villain unleashed his full power. 

13.) Ayesha - Elizabeth Debicki

Guardians of the Galaxy Vol. 2
Elizabeth Debicki as Ayesha

After serving as one of the villains of Guardians of the Galaxy Vol. 2, Elizabeth Debicki returned as Ayesha, the High Priestess of the Sovereign. 

In the film, Ayesha was mainly seen ordering Adam Warlock to wreak havoc against the Guardians. However, the villain ultimately died during the destruction of Counter-Earth, forcing Warlock to reflect on his allegiance. 

14.) Cosmo - Maria Bakalova

Guardians of the Galaxy Vol. 3

Maria Bakalova played the voice of Cosmo, a telepathic Soviet dog who is a full-fledged member of the Guardians in Vol. 3

The movie mainly tackled Cosmo and Kraglin's dynamic, ultimately resolving their petty fight when the former saved the latter against High Evolutionary's forces. 

Given Cosmo's importance in Marvel Comics and Guardians of the Galaxy stories, Vol. 3 likely won't be the hero's last appearance.

15.) Phyla - Kai Zen

Guardians of the Galaxy Vol. 3

While some initially thought that Kai Zen's MCU character was a glorified extra in the movie, Guardians of the Galaxy Vol. 3's post-credits scene surprised everyone when she became a full-fledged member of Rocket's team. 

In the comics, Phyla, who many deemed as the MCU's new Captain Marvel, is a genetically engineered being from Mar-Vell's DNA that has super-strength, speed, toughness, flight, and energy manipulation. 

A glimpse of the character's powers was seen in the post-credits tag, and it is expected that more of her heritage and backstory will be explored in future projects. 

16.) Blurp - Dee Bradley Baker

Veteran voice actor Dee Bradley Baker returned to the MCU as Blurp. The actor previously served as the voice of Morris in Shang-Chi and the Legend of the Ten Rings

Blurp returned in the movie's post-credits scene as one of the members (or mascot?) of Rocket's Guardians.

Lylla tragically met her demise in the hands of the High Evolutionary, with the villain killing her upon escaping from her cage. However, the character did return in a vision during Rocket's crossroads into life and death, telling her friend that it was not his time yet to join them. 

The emotional sequence served as Rocket's closure with his friends, thus completing his gut-wrenching character arc. 

18.) Teefs - Asim Chaudhry
