for navy and lonely pearl, the information you added was not supported by canon. for ruby and garnet, the wiki doesn't include regenerations that weren't seen in the present timeline of the show on character pages
I need help with a edit. Memin' Universe SU already finished most of it but the last 2 steps are some tricky ones. I'm trying to add the Infinity Train numbers on Stevens body from his neck, down to his hands, and ending at somewhat halfway where his gem is. (sorry for the big png i dont know if smaller means worse quality?)
he didn't appear in "too far", so it seems weird to categorize his age based on that. also, he may have turned 40 before that episode, or after. we don't know
as for the other characters, i don't know i haven't been paying attention to their age in the infoboxes. i'm not sure what their age is based on when it comes to that, aside from garnet stating her age in "the answer"
