Anyone remember how old she was back in Generation X? I mean, she's gotta be at LEAST 20 now, right?

I wondered that myself after reading Wolverine and Jubilee #1. I think I remember her being at least 15 in her mini series back in 2004/2005. I know comic book characters aged differently, but yea, I figured she would be 20ish as well.

I calculated her as being 19, actually.

The writers decided she was, they're the Gods of the Comic universe!

I felt the same way, but then I thought about it and 17 is about right. Comic characters can't age in real-time, I've come to realize this, time in comic books passes much too slowly for them to age in real time. Some people who've accepted this STILL think that that's much too young, but honestly if you're upset about Jubilee's age you have to be upset Tim Drake's age, as well. Both were introduced in the same year around the same age and if I'm not mistaken Tim's still 17 and even if he isn't, DC skipped forward a year and they're still roughly around the same age.

I am more interested in how old Bruce Wayne is supposed to be since he is from the 1930s era he should resemble his Batman Beyond looks by now

" I guess that means other Gen X members a.k.a Husk, M and Chamber are still 17 as well. "

" Yoga and Yak Milk.   Plus I just remember how annoying she was in Generation X, not how old.  "

1. Maybe becuase it comics I like it how they don't age quickly 
2.Does the vampire thing have anything to do with this I am not sure 
3.It's better if she stay that age

Something else that should be pointed out is that different artists have trouble with keeping a character's age consistent or drawing a certain age. So a character can be intended to be a certain age, but an artist will draw them in such a way that they look a different age. 

I'm sure if there wasn't a batch of "new" mutant kids after her she'd still be like 13-15. lol If we went by real time (counting how old characters were when first introduced)...most characters would be like 60+  ...I just try to ignore the age thing. I think Jubes would be around 35 by now. lol

 Ok, do we really want Sue Richards to be 67?  Emma Frost would look pretty sad being 57 and dressing like that. Catwoman would be a pretty hot 80 year old. Storm would be in her late 50's,  and Lois Lane should be in her early 90's (it is about time for her to give up on snagging Superman).  
 
We really don't want our heroes fighting evil in Depends™.  If you can suspend your disbelief to allow a man to fly or make laser beams come out of his eyes, you should be able to respect characters remaining timeless.

I can see why she would still be 17 seeing as how everybody else seems to only have aged a few years since their first appearance. Its a comic book thing.

I think that by now she should be in her early 20's simply because characters like M, Husk and Chamber, who I assume to be roughly the same age (or only slightly older at the very least) as her, are currently portrayed as twentysomethings. But I guess they're now writing her as someone who is still in her late teens.
 
I don't think that publishing "birthdates" matter when it comes to the ages of mainstream comic book characters. Time in comic boon universes doesn't run like time runs in real life because of the infinite structure of the stories. The stories are not planned to have definite endings because another writer is always going to continue where the last one ended, and that's why the characters go on existing from decade to decade. The in-universe present always resembles the present of the publication date, at least as far as things like fashion and pop culture references go. Time goes by in comics, but it has no decaying impact on the characters. The characters evolve, but they do not age significantly unless aging has something to do with a story, or their character developement. Characters can go through enough adventures to keep one busy for a whole decade and still act like not even a year has passed. They can also exist in several different places and teams around the world seemingly around the same time (yes, Wolverine, I am looking at you) without anyone even raising an eyebrow at the sheer impossibility of it. But none of that matters, because it's just the way time is in mainstream comics; it is not entirely consistent with time in real life. That's why Jubilee, despite everything she's been through, has apparently not aged past her teens during her publishing years.
 
I used to find the lack concistency with time and ages in mainstream comics extremely annoying, but I've since begun to find it intriguing. The academic geek I am, it reminds me of Mikhail Bakhtin and his concept of chronotope in literature, which means the different ways time and space are referred to in the bounds of language (or, as in this case,, types of literature). I think it's interesting how mainstream comics have developed this unique way of dealing with time, and how drastically it differs from the standards of Western storytelling which usually tends to be very linear, and specific about measures of time. The only thing that really annoys me about it is how child characters can't grow older unless they timetravel (hello, Layla Miller, Cable, and Hope Summers!).
