The Physics Of a Slightly More Physics Accurate Superman...

[Spacescifi]

This is simply an analysis of what a superman-like character would be like, at least from a durability standpoint.

Inertia Man: His body (not including the hair which is normal as anyone elses) has the same inertia and imaginary density as if his weight per kilogram was converted into tons. So lets say he weighs 77.111 kilograms which means his inertia and imaginary density is equal to 77.111 tons.

I say imaginary density because his body merely acts as if it has the density of 77.111 tons but is not actually 777.111 tons dense compacted into a human body... because he would overheat if it actually was. And this does not include his hair because his hair not blowing in the wind would look weird

He also has the power of superman style flight, out of necessity really because I have a feeling any human sized object weighing 77 tons would leave craters everywhere they walk.

Also inertia man can turn his inertia bending powers on and off at will, which allows him to lead an otherwise normal life when he wants to.

When inertia bending is turned on typically he tries to stay airborne to avoid making craters or sinking his feet into the ground. So he hovers a lot when talking to people when his inertia bending is on.

Durability: Could definitely take bullet shots without phasing him and fly through buildings with relative ease. Flying through mountains really fast though could injure and even kill him if done fast enough.

He would be heat resistant but not heat proof, since a human sized objecf that is 77 tons dense will be a lot harder to burn through than any normal object.

Fights: No human could ever pick him up, and anyone trying to fight him would fail at even pushing him even while he is hovering because of his imaginary density. Assuming he ever fought a villain with inertia powers like himself the excange of punches and kicks would be very loud. As you should expect when 77 tons or more hits 77 tons or more. A human touching inertia man's skin with their fingers could not make an impression mark anymore than they could do it with a statue.

Walls: Could easily press his hand through them, also easily bend or break through steel.

Nuclear bombs: He could likely survive one exploding in his face. Though it may or may not knock him out. That said he may suffer burn injuries if close enough as well as radiation damage.

So did I get my analysis correct? Anything I miss? And exactly what could kill inertia man quickly besides crashing into stuff at really high speeds?

Conclusion: In some ways he would seem more durable than classic Superman while weaker in others, since even Superman has been embarassed by Batman picking him up and throwing him (in the animated series). He could not do that with Inertia man.

You should read Larry Correia’s Grimnoir series.  I think you’d like Jake.  First book is Hard Magic.  Think Humphrey Bogart gumshoe in WWII era meets Harry Potter for grown ups.  Alternate history obviously

Given you stipulated his hair was normal it would be safe to assume his eyebrows and hair would be gone

In 1971, Larry Niven published some insights on Superman's ability to have a normal relationship with a human woman (Lois), given his superpowers, with Man Of Steel, Woman Of Kleenex. (Warning: Adult themes).
