This is regarding another Lucasfilm Marvel Adaptation that has different or incorrect art from the film.
The Howard the Duck 1986 Movie Adaptation has amazing art from Kyle Baker (one of his first Marvel jobs and he drew it with huge style). The final monster in the film was the huge scorpion looking creature beautifully designed by Phil Tippet. In the comic adaptation, this creature is missing and is replaced by a giant Duck that looks just like Howard but huge and monster sized.
It’s really strange and obviously a place holder of some kind. It makes me wonder how late in the design process they settled on that Scorpion and what Kyle Baker was told to put there. Also from my own memory that adaptation came out a few weeks after the film came out which means they never even went back to correct it knowing it was wrong and let it publish with the incorrect monster at the end.
