Mindboggler

Mindboggler is a supervillain in the DC Comics universe. She is an enemy of Firestorm and was given powers by Breathtaker of the Assassination Bureau. Her powers allow her to create convincing illusions and induce feelings in her victims. This lead her to become a high-priced assassin for hire, although she has also sometimes worked with heroes.

History
Mindboggler's name was never revealed. She was a criminal that fought against Firestorm on a few occasions, usually losing to him. 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 after he sexually harassed her other teammate Plastique, embarrassing him. He swore he would have his revenge on her.

The Suicide Squad is sent to destroy the terrorist group Jihad (DC) in Qurac. Mindboggler is tasked with keeping the soldiers occupied in their fortress Jotunheim. Rustam gets behind her and prepares to cut her down with a machine gun. Captain Boomerang witnesses this, but decides not to intervene and leaves her to die because she humiliated him. Rustam murders Mindboggler, and Captain Boomerang tells the rest of the Suicide Squad he got there too late.

The terrorist group Jihad later used a digital assassin called Ifrit, similar to their earlier member Djinn. Ifrit had the appearance and personality of Mindboggler. She was used to attack the Suicide Squad. Mindboggler later returned as a member of the Black Lantern Corps.
