Character Ages between versions
This post has its content sourced from the Japanese wikipedia article on the 009 series, and it might be of some help in creating the articles for the different incarnations of the characters.
Among the fanbase, it's first important to know the terms used for distinguishing each series, and which characters' ages would fall under which.
I'm not certain if Ishinomori's intended ages for the characters all fall in line with the early anime installments, seeing as 007's age was altered. But let's see. 009 and 001 are left out below since their ages always remain the same.
Old Showa ('60s films by Toei, 1968 series): 002 is 22, 003 is 16, 004 is 28, 005 is 31, 006 is given a vague "late 40s", and 008 is 21. 007 becomes 9 due to executives wanting a child on the team.
New Showa (1979 series, Legend of the Super Galaxy): All ages same as above, except 003's age is slightly raised to 17 and 007 (with them no longer going with the kid idea) is stated as "late 40s".
Heisei (2001 series): 002 is de-aged to 18, 003 is now 19, 004's age is slightly raised to 30, 005 loses a few years and becomes 27, 006 and 007 are given more respectively clear-cut ages of 42 and 45, and 008's age is raised to 22.
Then the 2001 series also has 001- 004 debut in the '60s before being put on ice for 40 years, so add more of a gap between them and the others.
I'm not sure if there are any guides stating the ages of the characters in 009 RE: Cyborg, or in Archaia's version. Dr. Gilmore always seems to be set at 63, though (except when we see him younger in the 2001 series' flashbacks).
ETA: Also, while I'm not certain what Ishinomori's original intent would have been for "Conclusion: God's War", it appears the existing novel and manga altered the backstories of the 00 Cyborgs to have their adventures take place in the 21st century (spanning 2005-2011). I don't think any age differences are mentioned on the Wikipedia page, though.
Further edit: Unsure on whether to actually include the '80s film under the "New Showa" continuity. The character designs are different, the feeling is also different, and 004's backstory seems to be updated compared to what was seen in the '79 series. It might be its own oneshot deal, but then, it might not be enough to make separate profiles for the characters that correspond to it.
