Jubilation Lee, codename Jubilee, is a Chinese-American member of the X-Men. She’s been around since 1989. Her powers involve making what she refers to as “fireworks”, bright energy bursts from her fingers. She ended up losing her mutant powers in 2005, and nowadays she’s… a vampire
(Twilight’s impact was strong), with the full array of vampire powers.
She was a main character in the (great) 90′s X-Men cartoon, and is going to be in the 2016 X-Men: Apocalypse movie portrayed by a rather new actress, Lana Condor. Hopefully she’ll be wearing her trademark yellow coat & those glasses.
Some of her relationships include a great father/daughter-like bond with Wolverine, friendship with Gambit, and X-23 (female clone of Wolverine, pictured below)
and she has a son she adopted, named Shogo. He’s a cute little baby now, but she did meet an adult version of him from an alternate reality, and it was great (single image pictured below, but more of that interaction here)
Fun fact: Her and Robin (Tim Drake) once had a little thing together, in an old DC/Marvel crossover.
So yeah, she’s pretty cool. You can check out my Jubilee tag if you’re interested in seeing more of her.
