Ruby Thursday first appeared in The Defenders #32-33 (February–March 1976), and was created by Steve Gerber, Sal Buscema and Jim Mooney.

2 #1-3 (May–July 1989), Web of Spider-Man #73 (February 1991), Deathlok #2-5 (August–November 1991), Marvel Comics Presents #97 (December 1992), The Defenders vol.

Thursday was a scientist who grafted an organic computer to her head composed of malleable plastic that can assume any form she wills it to.

[4] She was forced to drop out after Jack Norriss (associated with the superhero team known as the Defenders) tricked her into revealing her non-human self at a public campaign event.

[2] She later partners with a large purple creature called Dibbuk (named after, but unrelated to a dybbuk) and bases herself in Las Vegas.

Police arriving on the scene see a superhuman man in costume (Omega) appearing to assault a normal woman (Ruby) in her car.

She steals his body from a Las Vegas morgue and attempts to dissect it intending to incorporate its technology into her head.

He uses her relationship with Answer to draw her out of hiding and throws the Rolling Stones album Flashpoint (which contains the song "Ruby Tuesday") into her chest apparently killing the biological portion of her body.

The results of Ruby's rampage are shown in the forms of cars being shot up, people traumatized by this, and a cab ending up through the front window of a bookstore.

[9] Ruby and the Headmen then fought the Heroes for Hire while attempting to transplant Chondu's head onto Humbug's body.

[12] As part of the "All-New, All-Different Marvel" branding, Ruby Thursday subsequently attacks a police station with Gibbon, Griffin, and Shriek.

The red spherical mass has the ability to alter its shape so she can form appendages or weapons, replenish herself, and project different bursts of energy.
