Doesn't Marvelous need a support mesh to add structure for the cloth? Maybe the idea is creating the main shape, importing it into Marvelous and then doing the cloth simulation...
I cant speak for the rest since non of my current titles are marvel, but the Disney Channel did in fact do Marvel. Ultimate Spiderman, Avengers Assemble, Hulk and S.M.A.S.H. All watered down and sifted without the strife Marvel characters go through to a large degree.
