After some time in jail, she was offered a choice by the Suicide Squad: She can serve on a deadly mission and have her jail term changed to time served, or she can remain in jail until her sentence was over.
Mindboggler decided to take the Squad up on their offer. Right after their debriefing, but before the actual mission, Mindboggler used her power of illusion on Captain Boomerang, embarrassing him. He swore he would have his revenge on her.
During the mission, Mindboggler was shot from behind by a member of the Jihad. Captain Boomerang had a chance to save her but let her die. She has since been incorporated into the computer system known as Djinn, a member of the Jihad.
