Mirage is the name of two DC Comics characters. The first was a minor villain of Batman. The second is a heroine who is affiliated with the Teen Titans.
The first Mirage was a man named Mike (also referred to as "Kerry Austin") and appeared in Detective Comics #511 (February 1982). He uses a gem that causes people to see elaborate illusions. He commits crimes while his victims are occupied fighting against these illusions. This crime wave brings him to the attention of Batman. Batman faces Mirage several times before coming up with a strategy to beat him. During the encounter, Mirage's gem is destroyed. Batman is able to defeat him and sent him to jail. While in jail, Mirage manages to create contact lenses from fragments of his jewel. He proceeds to create the illusion of himself in jail and escapes to the circus he once worked for. Starting another crime wave, Batman is once again alerted to his actions. This time, Batman easily beats him and sent him back to prison. Mirage also fought Manhunter once using his illusion so successfully, he nearly kills the bounty hunter.
Following the Infinite Crisis, Mirage is freed from prison again. He is killed in 52 #25 (2006) by Bruno Mannheim. Mannheim bashes Mirage's head into the "Crime Bible" and sends his body to the kitchen to be prepared for Mannheim to eat, revealing Mannheim is a cannibal.
Mike can create believable illusions in the minds of the people around him by using a gem of unknown origin. The gem projects both optical and audio stimuli.
Mirage (Miriam Delgado) is a fictional character owned by DC Comics. She is a former Teen Titan.
She was originally one of the Teen Titans who came from the future to kill Donna Troy before she could give birth to her son, who, in Mirage's future, became the evil dictator Lord Chaos.
After Donna sacrificed her powers to prevent that future from becoming real, Mirage and the other Team Titans relocated to Donna's farm in New Jersey. She had to deal with Killowat's intense crush on her and the more malicious intents of another man. Mirage was raped by her former lover Deathwing and became pregnant with his child. For a while she deceived her friends, using her powers to make it seem as if she had lost the child.
Mirage is part of the honor guard that escorts Superman's body to his tomb.
During the Zero Hour crisis, she found out she wasn't from an alternate timeline, but from this one. She was, in fact, a runaway street urchin from Brazil, whom the Time Trapper had kidnapped and implanted with false memories. Mirage remained a member of Arsenal's Titans team. During this time, her powers fluctuated. She experienced uncontrolled illusions. She found she could project an image to a spot where she was not and remain hidden all the same.
Eventually, she gave birth to a daughter, Julienne, and left the Titans to spend time with her.
She helps the Titans to save former Titan Cyborg in the Technis Imperative storyline. During a confrontation with the Justice League during this incident, she tricks the Martian Manhunter with an image of his dead wife and is violently subdued. She reappears again, alongside other former Titans, to help the new incarnation of the Titans defeat Dr. Light in the 3-part Lights Out storyline. Mirage was one of the Titans that battled Superboy-Prime near Smallville, Kansas in Infinite Crisis #4 and Teen Titans vol. 3, #32. She also rejoined the Titans for a brief period during the "one year gap".
In Teen Titans #99, she was one of the former Titans that came to aid the Teen Titans in the battle between Superboy-Prime.Teen Titans Go #48 features a version of Mirage (who resembles Raven) as a member of the Teen Titans in another reality.
Lord Chaos' rise to power soon resulted in Earth becoming a mobile battle platform. Miri became captain of a resistance ship, which Chaos took.
