Lillian Crawley (Earth-616)

The methods by which Department H found and recruited Lillian into Gamma Flight are unknown. She had a brief affair with Madison Jeffries after meeting him there, but the two would develop stronger feelings later.^{[citation needed]}

Delphine Courtney recruited Lillian for Omega Flight using a mind control device. Madison returned to destroy Delphine while Shaman kept Lil distracted with illusions.^{[citation needed]}

Lillian was pardoned for her actions as part of Omega Flight. She was angry at Jeffries' closeness to Heather Hudson, while Heather was angry at her for being part of the group that was responsible for her husband James' death.^[2] Guardian subsequently returned years later; Heather and Lil seem to have set aside their differences.^{[citation needed]}

Lillian began secretly seeing Jeffries while he was engaged to Heather Hudson. The two reaffirmed their feelings while both were fighting Diablo.^{[citation needed]}

Lillian had a breast cancer scare after feeling a lump in her right breast while doing a breast self exam on her breasts in the shower. This was especially difficult to deal with because her powers made normal removal impossible. While Alpha Flight battled aliens, she was harmed by a laser from one of them. She chased the being down, stole its laser, and asked Jeffries to modify it into a scalpel. She successfully underwent surgery; the lump was a benign cyst and she made a full recovery.^{[citation needed]}

Madison and Lil married and agreed to retire from active duty. However, Madison continued to use his Box robot. She worried he had become addicted to adventuring.^{[citation needed]}

When Alpha Flight reformed, Lillian was angry that Madison wanted to join the new team. They had a fight and parted ways. He came to the Department H headquarters in Toronto to join the team, while she went to take care of some personal stuff.^[3] Sometime later, Diamond Lil in full costume arrived at the headquarters building in search of her husband. Two members of Epsilon Flight arrived to escort her to the infirmary, where Madison was supposedly waiting for her.^[3] This was an obvious lie as Madison was at the time in the custody of the Zodiac.^[4]

Lil was captured by Dr. Horatio Huxley of Department K and experimented on. Thetagen-24 was injected into her system. While the previous subjects died, Lillian's powers kept it contained around her skin. Alpha Flight managed to rescue her. However, she did not rejoin the team.^{[citation needed]}

Lillian was captured by Weapon X and sent to Neverland. She and Random resisted when the guards began separating prisoners into who was suitable for being made an agent and who was not. They were severely beaten by the Boxbot guards, their powers negated by a dampening field.^{[citation needed]}

Lillian survived and retained her mutant powers after M-Day and was one of the mutants who sought refuge at the Xavier Institute during the chaos.^{[citation needed]}

Following the Institute's destruction, the X-Men's relocation to San Francisco, and the X-Men's establishment of Utopia, Lillian made her way to the island nation. There, she sought out her husband, initially frustrated at him for not understanding her needs. Slowly remembering his inherent inability to understand people, she came to forgive him and the two made up.^[5] A day after they had made up, Selene's forces invaded Utopia, and in the chaos, Lillian was killed.^[6] Madison buried her at sea in a glass box he made, symbolizing how he could always see her, but never felt as if he could effectively touch her.^[5]

• Superhuman Durability: Diamond Lil's body generates a bio-aura of nigh-impenetrable energy that permeates her molecular structure to grant her skin durability akin to that of diamond. Though able to deflect most forms of physical or energy-based impacts, Lil still feels the force of such blows. Similarly, Lil's bio-aura also affords her protection against temperature extremes. Her nails and hair are similarly permeated, even after being removed from her body.^[7]
• Superhuman Strength: Diamond Lil's invulnerable body seems to grant her some measure of superhuman strength as on Earth-7475 she has been able to fight toe-to-toe against She-Hulk and knock her out, throw Spider-Man against a wall with enough force to break his neck and kill him^[8] and deform Colossus's face with a punch.^[9]

Lillian is an excellent hand to hand combatant. Her natural durability also enables her to use nearly any part of her body as a weapon. Even a string of her hair can be used like a whip or a garrote.^[7]

Lil's bio-aura limits her sense of touch.^[7]
