One of the biggest surprises in Guardians of the Galaxy is the appearance of iconic Marvel character Howard the Duck (voiced by Seth Green). He shows up as part of the Collector's museum menagerie in the post-credits scene...Without pants! This was a big deal for fans, because back in the 70s, he was legally required to wear a full suit as to not be confused with Disney's Donald Duck. Both mallards now reside at the Mouse House, so that no longer seems to be an issue.
New concept art from Ryan Meinerding shows Howard wearing a full suit. But the look didn't change too drastically from the finished film. Check him out.
Ryan Meinerding is a longtime conceptual artist for Marvel. He is also a Visual Development Supervisor, with this being just one of his smaller contributions to the world of Guardians of the Galaxy.
