I’m not an astrophysicist, or any kind of expert in physics for that matter, but as I understand it a black hole has a certain boundary called the Event Horizon, the point at which gravity becomes so strong that nothing can escape once this threshold is reached.

Assuming (and we have evidence to suggest this) Invincible approximates real life physics, Omniman was “only” resisting the natural gravitational force a black hole of that solar mass would apply to an object outside the Event Horizon.

Still a crazy feat, but perhaps not as impressive as some people will think.
