The character of "Lockjaw" is at the end of that extreme. He's not a dog, he's an Inhuman)
They much later resurrected the Inhumans because of the movies, which really screwed over comics. But Marvel-Disney wanted something to replace the idea of "mutants" and apparently this idea...which wasn't much better than B-grade material, was the best they could come up with.
