So if Mister Mxyzptlk or some magical enemy decided to conjure a spell on Superman that prevents him from being exposed to the outer energies of the yellow sun, does Kal-El.lose his superhuman powers ?
Hypothetically, I would agree. Kal-El and other Kryptonians' cells are saturated with yellow sun energy, granting them their superpowers. Creating a barrier blocking solar energy would do the trick.
Mister Mxyzptlk has been around since the 40's. The imp has stolen Superman's powers in the past. Creating a barrier would not be a problem for him. However, the character has always been portrayed as an idiot, which is why his plans have always fallen apart.
Or since he's been exposed to the yellow sun of Earth since discovered childhood is Clarke's body cells " permanently" enhanced by the has the solar energies of the Earth ?
No. It would take a long time but practically all Kryptonians, even those who have bathed in the Sun's rays from since they were a baby, would be reduced to a normal human physically if cut off from solar energy.
The lone exception would be Superman Prime, who stayed in the Sun for 15,000 years. His cells are charged with solar energy beyond the imagination. It would be an understatement saying his internal solar storage would be deleted for centuries, probably millennia.
- So if it's according to his body cells, then those solar energies are " within" him so there could not be a " sun-shielding " that can deprive him of his super powers ?
That... would be more true of the pre-
Crisis of Infinite Earths Superman than the post saga version.
The old Superman's "internal batteries" were VERY far superior to the current version. Again, the previous Superman could fly out into space for weeks or months at a time and visit non-red sun solar systems without much difficulty retaining his superpowers, if that. The current Superman is constantly recharging his cells to retain his powers. If separated from the Sun's rays for an "extended time", Kal-El's internal solar energy capacity would slowly dwindle, along with his abilities.
-That's why it would make more sense for Superman's "enhanced" super powers enabling him to not needing to depend upon outer oxygen to breath.
His own internal self-sustaining energies should allow him to do.
Just my opinion but I think you may be stuck on the old Superman. DC depowered him and gave him greater limitations. It may seem like illogical thinking on the publisher's part but I agreed with their course of action.
For example, it was that forward thinking that allow an eventual discussion of the killing of Superman.
The Death of Superman, and even the creation of a now classic killing machine like Doomsday, would not have happened if not for the depowering of the Last Son of Krypton. Old Superman would have easily flicked that sucker into outer space before 1985, lol.
- Much like the Silver Surfer who also was a mortal who ended up being enchanced by external force, en route to Not needing oxygen to breath. .
I do not agree with the comparison. Norrin Radd is a recipient of the
Power Cosmic. Mortal limitations do not apply to him.
- There seems to be more confusion with DC Comic profiles with some of their characters than Marvel .. ...
Superman is still flawed but he is who he is now. I would be against DC reversing course and returning the old version.
