I love you blatantly and outright ignore evidence to try to push your bullshit agenda.
You've gone very deep into the area of trolling now.
We actually have several examples of verifiable proof of him dying and being stronger when he comes back. After the Radiant, After the Guardian, after Superman. All who pushed him to the limit of his power and then used a final blow to put him down.
He evolves, and comes back stronger than before. It is the basis of his stories. it is the nature of his character. It is written in his bio as the source of his power.
We also have several examples of him not being "all out" all the time.
From his encounter with the GL, where he got challenged and amped it up until he won.
To walking over GLs until encounter a Guardian and ramping it up he was taken to his limit and stopped. A continious ramping of power over the course of the story.
From his casually walking over JLA members as if they were insects, and then encountering Superman, and ramping it up the entire fight until he hit his limit and Superman punched him to death in the middle of town. A continuous ramping of his power until he was ended. And then came back stronger in H/P. So strong only Entropy could stop him.
You're also still trying to push this bones and sunlight shit as evidence.
Doomsday's power is not linked to his bones, nor is it linked to the sun.
I have given on panel and bio examples of sun being said to be his sustenance , and his actual power being listed as separate from this idea. That his power and strength is specifically said to be derived from evolution and rage. I haven't seen any evidence that Doomsday gains power from the Photonucleic Effect like Kryptonians do.
Conversely we also saw later down the road, after his death to Imperiex Doomsday actually WAS spliced with Kryptonian DNA to rebuild him, and gained weakness to Kryptonite until he evolved passed it. This further suggests, beyond the fact he wasn't from Krypton at all, that the common Kryptonian attributes were not part of him already.
I have also given examples of his bones being grown at will. Which is exactly what was done when he was still underground punching at the wall. Or Superman remarking his bones grew in Hunter/Prey. Or using them as projectile weapons in Hunter/Prey.
Every piece of information available to Doomsday's story fits into this model.
On the flip side, you have zero evidence to support your agenda you keep pushing that he was somehow weaker. That he doesn't ever hold back. That his bones are identifiers of his power.
I mean literally nothing you have tried to use supports you while you sit here and ignore the facts and scans.
