Animation in Japan tried top quality Art to add to their story telling. The high level art never made much difference to the success of the anime. Just because one anime is doing really well just has good art style as an added feature. But historically speaking Best drawn art rarely makes up for bad story lines.

Superman never really existed. He has so many powers his limits were only limited to an imagination. Clark had a boring job and he day dreamed about what if's as his multiple personality delusional disorder was his coping mechanism. He lived and felt his thoughts; but in the end is stories would bring him back to his job and normal life.

Ability to make someone forget something sounds like it came from a 8 year olds mind that was caught in his first kiss 😂

Anyways. Superman has infinite powers and unlimited potential. Just don't bring up kryptonite. Maybe kryptonite was a key words for medical form of anti-psyco drugs.

Ok first off. Wolverine can't grow back a whole limb! Directly stated by Stan. (God bless him)

Secondly Magneto Tried this 2 times! Was never successful. Magneto in over powered form instead ripped all the adamantium right off his bones.

In that comic Wolverine healing ability and tendons was woven into the adamantium. Took Logan 3 comic books to heal from the damages.

So if you think about it Logan or Wolverine limbs weren't lost when adamantium was stripped off his bones that all was woven and bind too. Then he can't technically loose a limb.
