Ming-Na Wen, Henry Winkler, and Raven-Symone are slated for unspecifed guest roles in the upcoming third season of Disney XD's Guardians of the Galaxy cartoon. Scheduled to debut March 18, the series is subtitled Mission Breakout - take a look at the announcement trailer:
Who could these three actors be playing?
The one-time Fonz Henry Winkler has become a veteran voice actor, but never in a Marvel production - he did play Ambush Bug for DC once however.
Raven-Symone is a staple of Disney TV, and has done numerous cartoon voiceover roles - but none in Marvel Animation.
As for the live-action Agents of S.H.I.E.L.D. actor Ming-Na Wen, the most obvious option would be carrying over her Melinda May role - who was last seen in space with that live-action series.
The Guardians of the Galaxy cartoon's third season, subtitled Mission Breakout, is scheduled to debut March 18 on Disney XD.
