Well, obviously the one on the left is from a different game than on the right, and a part of these bios is/may be the games this character has been in. So, I suppose in a sense the bios would pretty much be the same, except for the game section. Unless in order to save a page one could direct both pic-links to the same page, and in the game section just say [young zelda] or [mature zelda] for whichever game corresponds accordingly.
The two Zeldas are, in fact, two different people, from different eras/timelines, and therefore would have completely different backgrounds. There are multiple Links as well.
This might be an issue for the two Samus mascots, though.
