How powerful is this black hole feat?

[The_real_cal_howard]

I just thought of this on the fly. It's not about a character I plan to add on here, but an OC.

The stronger a character gets, the greater his mass gets (they don't gain body fat or muscle because lolpowers. Stays at relatively the same volume the entire time: a 6'1" mesomorph), and therefore his density, until the point where he'd collapse into a black hole. He doesn't collapse, beause again, lolpwers, though gains gravity/density/black hole powers in the process.

What would be his lifting strength and tier solely for being able to hold himself upright?

What would his tier be if calculated as a black hole?

What would his tier be by moving at relativistic speeds? Let's use .71 c (random number)

If Newtonian KE still worked past FTL here, what would his tier be moving at 50c?

Well talking abouth black hole is hard because scientist cant for sure say how they work.

I mean, a black hole doesn't have a proper density. Best way to calc it would be something like finding the equivalent spherical volume, from that the radius, then equating it to the radius of a black hole. From this point onward it would be the average black hole calc. But I don't know how to find the initial volume D:

I'm not sure about anything here, since there is a lot of conflicting information about it, and no one can be sure about anything, but...

If you take account the singularity within black holes, he'd need to lift an infinite amount of mass. That may not be the case, just pointing this out.
