What is superman's strongest form???

Pre-Crisis superman, Kingdom come superman, superman 1 million, superman merged with kismet, or platinuim superman prime?

I believe the answer is Prime.

hence the name: superman PRIME!

Hmm...

Prime apparently.

But until we have feats for him, then it's Pre-Crisis. 🙂

Red Son is awesomely powerful too.

well prime has done enough to be beyond pre crisis, and hint prime mean numero uno, so he's the number one superman... its in the name!
