Krystalin is a fictional character in Marvel Comics's 2099 universe, a look at superheroes in the year 2099. She was one of the founding members of a future incarnation of the X-Men called X-Men 2099.
Very little is explained about Krystalin's past before joining the X-Men. Her father was a founding member of the Order of the Panther in Oakland, a para-military force inspired by the Wakandan traditions. Her mother died while she was young, leaving her and her brother Zac with their father. While Zac followed the traditions of the Panthers and succeeded their father, Krystalin left with Meanstreak to explore her mutant heritage and joined Xi'an's X-Men. In her first appearance in the story she helps Bloodhawk escape from the Synge Casino and helps the other X-Men clear Xi'an of false charges that he killed casino boss Noah Synge.
While the other X-Men left on a mission, Krys was sent by Xi'an to El Paso to meet Xi'an's former Lawless teammate Victor Ten Eagles and investigate sightings of an "Archangel"-esque creature flying through the mountains. There, she encounters Zhao, leader of the last known generation of X-Men. Zhao had genetically engineered a team of X-Men with powers analogous to Xavier's original 5, though the process left them unstable awaiting an eventual death. Zhao brainwashed Krys and Victor, using them to lure the other X-Men to Zhao's compound, where he planned to brainwash them all to follow him as his new X-Men. Zhao is defeated by Xi'an, who defects from the team to join the Theatre of Pain.
Please release me, let me go,
For I don't love you anymore.
To live a lie would be a sin.
Release me and let me love again.
I have found a new love, dear.
And I will always want her near.
Her lips are warm where yours are cold.
