Man of action and Paul Dini are the actual producers and developers on Ultimate Spiderman and have full control of the cartoon, Marvel animation is merely a supervisor and publisher for the show. Of course Marvel is allowed to speak for cancellation but still, It's all up to Paul Dini and Man of Action.
