Franklin is probably around 8 (though he regresses in age sometimes).

I prefer to use the 10 year rule, but I know others like to use the 12 or higher year guide.

In thinking of their ages, I try to think what age they were when first introduced, and when they were introduced in the Marvel U. For me, Spider-Man was introduced at the beginning, and was 16 at the time. So I would add 10 to that age.


Mr. Fanastic- 40
Thing- 40
Invisible Woman- 34
Human Torch- 26


Around 28 when WW2 hit. Add the years up for his real age. I would say he is in his 50s by appearance.


26


Late 30s by looks.


20. I think she was stated to be 18 recently though.


16.


Johnny Blaze- 35


30.


35.


Late 30s.
