[Carlisle does know about the Paradigm, at least in the sense that it was a thing that existed. Comprised of Qubit and presumably the people in the painting with him, they'd been described as 'Earth's mightiest protectors.' That was the intent, anyway, Qubit had said, which implied things had gone terribly wrong somewhere along the way. Further evidence to that end was that there were only two others left when Qubit had been spirited away from his world, the rest likely dead or gone.

The main one of note was the Plutonian, and the way Qubit talked about him — Tony — made it clear that they were friends, and that Qubit cared immensely for him. It was with him that the aforementioned something had gone wrong, as somewhere along the line, a lot of children ended up as skeletons; he wanted to fix whatever mistake had caused that, and couldn't. No one could — not even Qubit.

How that lead to the downfall of the Paradigm is something Carlisle doesn't know, along with—]

I'm not even sure what a 'superhero' is, or how it differs from a regular hero. Aside from the obvious implication. And this is the first I've heard of your being one.
