Young Justice raised an interesting question about her. They were talking about her eligibility to join the League, but it can apply to this just as easily. The League was discussing whether age should be a factor in recruiting for the League. Martian Manhunter pointed out that M'gann was biologically an adolescent, but chronologically, she was born like forty-some-odd Earth years ago. On Earth? She's over forty years old. By Martian standards? She's still an adolescent. Which point of view matters most here?
