Who did Miley Cyrus play in Guardians of the Galaxy 2?
Miley Cyrus was the voice of the robot Mainframe in Guardians of the Galaxy Vol. 2 back in 2017.
You’d be forgiven for missing the cameo since it is only the singer’s voice that can be heard, and the clip is nestled into one of the movie’s post-credits scenes.
If you want to find the scene for yourself, you can stream Guardians of the Galaxy Vol. 2 on Disney Plus and find the cameo around 02:08:40 on the timestamp.
Mainframe appears in the post-credits scene teasing the Ravagers – who Gamora is a part of in Vol. 3 – alongside Sylvester Stallone’s Stakar and Michelle Yeoh’s Aleta.
Cyrus performs the line “I miss you guys so much.”
Tara Strong takes over as Mainframe in Guardians of the Galaxy 3
Despite many believing that this was Cyrus’ MCU debut, the character never returned as Mainframe nor appeared in any other roles in Marvel Studios.
Therefore, it was recently announced that iconic voice actor, Tara Strong, would be taking over as the voice of Mainframe in Guardians of the Galaxy Vol. 3.
Strong, whose credits include Teen Titans and the voice of Miss Minutes in Loki, will reboot the character alongside the Ravagers once again in the upcoming sequel.
