Can Superman and Supergirl populate an entire new generation of Kryptonians and eventually a planet like Krypton-I, or something? Why not? So the questions are:

(a) Can they biologically produce more superkids.

(b) If (a) is true, will they be on earth or they will colonize other planet? (like moon then rename it to Krypton-I or something) whether they are able to foster an entire generation.

  • I’m a little unsure about what you’re asking here. Are you asking whether it is biologically possible for Superman and Supergirl to procreate? Whether such a population would be stable? Whether they could find a new planet similar to Krypton? Whether this will ever happen? – Adamant Oct 2 '16 at 7:21
  • Yes, biologically possible, not find a planet, but move to other and stay there then eventually it will be called something like Krypton. – Talha Oct 2 '16 at 7:23
  • So…which of those things are you asking about? – Adamant Oct 2 '16 at 7:23
  • Is this possible biologically? If yes then second question is whether to move to other planet or not. – Talha Oct 2 '16 at 7:24
  • So you are asking whether the entire rather specific sequence of events could happen? – Adamant Oct 2 '16 at 7:25

You need more than 2 people to form the basis of a genetically stable population - especially those that are not already related by blood (Superman and Supergirl are cousins, after all).

    If the Super-family don’t mind some human genetic material being mixed in, I’ve decided I’m willing to lend my assistance to this noble endeavour. – Paul D. Waite Oct 2 '16 at 12:29
