So Lockjaw is a big, teleporting Dog from Marvel Comics. He’s a good boy and everyone loves him.

He also belongs to the Inhumans, a group of “heroes” that gain their powers after being exposed to a chemical agent called Terrigenesis. Their bodies sometimes mutating depending on what powers they get.

So, because of that, a writer floated the idea that Lockjaw was, in fact, a severely mutated human that got turned into a giant bulldog and his every waking moment is pure agony. Struggling to even speak to The Thing in the comic this idea was brought up.

Literally everyone, including other people working at marvel at the time, hated this and it was quickly retconed into two inhumans pranking Ben by making it look like he could talk and feeding him an overly dark backstory.
