It’s certainly unsurprising that Rob Liefeld’s catalog of characters is getting a closer look.
That’s not a dealbreaker, even Deadpool wasn’t exactly a household name for your average movie fan, but the fact that the character had a relationship to the existing X-Men characters certainly helped.
Prophet exists in an entirely separate universe, having been created for Image Comics rather than Marvel.
Part of the problem, of course, is that few of Liefeld’s creations are quite as well known as Deadpool, or the associated characters like Cable.
