What Major Star Secretly Voiced a Character in ‘Guardians of the Galaxy Vol. 2’?

Since the 2014 release of Guardians of the Galaxy, then its follow-up/Marvel tie-in, Guardians of the Galaxy Vol. 2 three years later, fans have been waiting for the third in the franchise. That said, Vol. 2 offered a slew of celebrity cameos you might not have noticed. In fact, there’s one celebrity with an instantly recognizable voice easily missed. Read on to find out who it is (then redeem yourself and re-watch the film ASAP).

‘Guardians of the Galaxy’ films have big-name characters you probably didn’t realize are there

While everyone now knows Star Lord is played by Parks and Recreation star, Chris Pratt, the Marvel movie employed plenty of other actors tucked into costume, makeup, and voice-overs.

For instance, This Is Us alum, Chris Sullivan, played the ever-affable Taserface, a mercenary and a lieutenant in the Yondu Ravager Clan. Musician and horror fanatic, Rob Zombie, plays another Ravager not seen on camera but heard.

Likewise, Seth Green (Buffy the Vampire Slayer and Robot Chicken), lends his voice to Howard the Duck. David Hasselhoff, who does appear as a version of himself briefly, contributed to the soundtrack (who knew?).

Still, one celebrity appeared in the final credits — a small but mighty role. If you blinked, you’d have missed it.

Who voiced a character in ‘Guardians of the Galaxy Vol. 2’?

In the Guardians of the Galaxy Vol. 2 end credit scene (which they’re known for, often by linking the next Marvel film), there’s a small robot, Mainframe, who’s supposed to be the newbie of the “new” Guardian group, led by Sylvester Stallone’s character, Stakar Ogord.

Mainframe and Stakar are joined by Martinex (Michael Rosenbaum), Charlie-27 (Ving Rhames), Aleta (Michelle Yeoh), and a CGI Krugarr.

“I miss you guys so much,” Mainframe says in the video.

If you can’t put your finger on the robot’s voice, it’s none other than Miley Cyrus. Yep — that tiny cameo makes Cyrus a part of the Marvel Cinematic Universe indefinitely. Will she return in Guardians of the Galaxy Vol. 3?

Writer and director, James Gunn previously told Buzzfeed News it’s a possibility.

“She knows that there’s a chance that the character may go on and become a bigger thing,” he said vaguely. “I’m excited by the possibility of doing more stuff with that particular set of characters.”

If Cyrus does reprise her role as Mainframe, it’s unclear how big her part would be. Marvel Studios President, Kevin Feige previously told Collider a future appearance by the character could be anything from “a Howard the Duck level appearance” to “a large part in a future movie.”

It’s anybody’s guess as to whether fans can expect more of Cyrus’s vocals in the next Guardians installment or if the cameo was thrown in for the fun of it and nothing more.

Has Cyrus done any other voice work?

Cyrus has voiced other characters in the past. With a unique voice like hers, it’s clear why. Gunn admitted he’d been a fan of Cyrus for years, admiring her voice in particular. Others have felt the same.

In the past, Cyrus voiced Penny in the animated film, Bolt. She’s also played Celebrity Starr on The Replacements, and Yatta on The Emporer’s New School.

The singer’s talents are limitless. Now that she’s recovered from vocal cord surgery, maybe fans will hear her on a lot more projects (like Guardians of the Galaxy Vol. 3).
