[2] Within the Marvel Universe, Crystal is a member of a fictional human subspecies known as Inhumans, who (due to genetic modifications performed by the Kree) became capable of developing superhuman abilities once exposed to the Terrigen Mist.

In later stories, she becomes more associated with the X-Men family of characters due to her short-lived marriage to Quicksilver, which resulted in the conception of their daughter, Luna.

Crystal has also appeared in various other Marvel media such as television series and video games, as well as merchandise such as trading cards and action figures.

[4][5][6][7] She made her live action debut in the 2017 Marvel Cinematic Universe (MCU) television series Inhumans, portrayed by Isabelle Cornish.

Crystal first appeared in Fantastic Four #45 (Dec. 1965), written by Stan Lee and illustrated by Jack Kirby, titled "Among Us Hide...The Inhumans".

At this time, the character returned to her family in Attilan due to her apparent inability to survive long-term in Earth's polluted atmosphere.

During this time, Crystal is mostly featured alongside Quicksilver in a number of different series including Inhumans and Vision and the Scarlet Witch, along with guest appearances in Fantastic Four, Avengers, and other titles.

A few months later in X-Factor Annual #2 (October 1987), it is revealed that the behavior exhibited by both Crystal and Pietro was the result of mind control orchestrated by Maximus.

Crystal departs the team abruptly in Fantastic Four Annual #21 after being convinced to do so by her king and brother-in-law, Black Bolt.

The series, which was part of the Marvel Knights line, was critically acclaimed, popular with readers, and earned Jenkins an Eisner Award.

These books chronicled Quicksilver's betrayal of Crystal and the Inhumans in an attempt to use the Terrigen Mist to restore the mutants depowered during the events of House of M and the resulting conflict between Attilan and a fictional version of the United States.

Secret Invasion: Inhumans (2008–2009) by Joe Pokaski marked the beginning as it was discovered that Black Bolt had been replaced by a Skrull.

This revelation leads to a series of events that eventually sees the Inhumans ascend to become sovereigns of the Kree Empire and Crystal betrothed to Ronan the Accuser.

During this time, Crystal showed her prowess not only as a warrior, but as a leader, as she and her family navigated political and military conflicts, particularly against Vulcan and the Shi'ar Imperium.

Although present in Infinity (2013) and Inhumanity (2013–2014), which, under new authorship, continue the events portrayed in Abnett and Lanning's aforementioned series, she does not play a major part in these books.

[17] She left New York with her family members to escape the Seeker, but became trapped inside Maximus' "negative zone" barrier dome around the Great Refuge.

The Inhumans were eventually freed from the "negative zone" barrier, and left the Great Refuge along with the Royal Family to visit the outside world.

[32] Crystal and her sister Medusa are called upon by Iron Man to a meeting where he reveals Black Bolt has been replaced by a Skrull.

She comes to accept the idea of the marriage, defending it to her sister-in-law Polaris as a matter of statecraft (though there are indications that Ronan wishes for more).

[34] The wedding proceedings are interrupted by the Shi'ar Imperial Guard, who attack as part of Emperor Vulcan's invasion of the Kree Imperium.

[35] When Black Bolt attempted to set off an explosion that would spread the Terrigen Mists across the galaxy, reasoning that this action would render all equal, Crystal defied his orders and risked her life to take Lockjaw to confront him, disabling the Terrigen qualities of the explosion and convincing Black Bolt that the powers that would be created by his plan would cause more harm than good.

[44] Using this ability, Crystal can summon wind currents strong enough to support her weight and others'[45] and elevate herself to fly at high altitudes and speeds.

[50] Crystal can control the various substances that make up common bedrock (earth: iron, granite, shale, limestone, etc.

), creating seismic tremors of up to 6.7 on the Richter scale (greater if tectonic plate fault lines are nearby) by causing a sudden shifting of the earth.

[43] The upper limit of this power is unknown, although she has demonstrated the ability to lift the entire fictional city of Attilan for a significant amount of time.

[52] Crystal possesses the psionic ability to manipulate fire, cause it to grow in size and intensity, and take any form that she desires.

The maximum volume is unknown, although she has demonstrated the ability to create a maelstrom large and powerful enough to trap at least a dozen individuals, including Namor,[47] and brought down what was described as "a sea from the sky," at least several thousand gallons.

[45] By combining her abilities to manipulate air, water, electricity, ice, and temperature, the character is able to effectively control the weather within a 30-mile radius.

[61] Steve Morris of ComicsAlliance asserted, "Crystal's elemental powers offer infinite possibility, but her most important trait may be her pragmatism.

"[62] Sara Century of Syfy stated, "We like Crystal a lot because she is a character who tries to choose her own happiness, only to get shunted off into politically convenient arranged marriages off-planet at the drop of a hat by the people closest to her.
