Danny Chase

Danny Chase (later called Phantasm) is a fictional superhero in DC Comics publications.
Publication history.
Phantasm first appeared in "New Teen Titans Annual" Vol. 2 #3 and was created by Marv Wolfman.
Fictional character biography.
Danny Chase was a short-lived member of the New Teen Titans. He was raised by parents who were international spies. As a result, he was extensively trained in espionage, infiltration and intelligence acquisition. In addition, he was a metahuman with powerful telekinetic abilities and a near-photographic memory. Although Wolfman hoped the character would restore the "teen hero" feel to a group composed mostly of characters in their twenties, Danny was also intended as a comic foil for one of the group's foundational characters, Changeling (now Beast Boy).
Problematically, the character was often portrayed as an overly snide, egotistical brat. Conflicts with Beast Boy were one-sided, with Chase invariably delivering come-uppance. Meanwhile, other members of the team proved prone to commenting on how impressed they were by Chase's cleverness and capability. All of this made him something of a "Mary Sue". This quickly proved unpopular with most fans, and pro and anti-Chase letters sparked heated debate in the letter column. Wolfman tried various ways to make the character more appealing to the Titans' fan base, including having him briefly disguised as the mysterious "Phantasm" during the "Titans Hunt" storyline. 
The creation of the Phantasm identity.
At one point early in the Titans Hunt storyline, Danny Chase found himself confronted by two members of the Wildebeest Society inside a shopping mall. One of them blasted him away and assumed him to be dead. He had survived and decided to use his telekinetic powers to assemble a costume of sorts from assorted items - a hockey mask, a bolt of fabric, and a robot-voice simulator to disguise his voice - and present himself as the "Phantasm" in order to remain incognito. However, negative fan pressure was strong enough to write Danny out of the series.
In the end, the character was redeemed somewhat when he willingly gave up his life to save Raven's homeworld of Azarath as he, Arella, and the disembodied souls of Azarath were all merged into a new entity that would also refer to itself as the Phantasm who wore the costume that Danny Chase was wearing.
Danny Chase's body briefly returned as an undead slave to Brother Blood in the third "Teen Titans" series (2003-2011), in issues #30-#31 (Jan-Feb 2006), in a storyline written by Geoff Johns.
One Year Later, Zachary Zatara mentioned that he and Kid Devil went on a trip to New Azarath where they were almost eaten by the Phantasm.
During the "Blackest Night" storyline, Danny Chase's body was briefly revived as a Black Lantern in the "Blackest Night: Titans" miniseries. However, his body was soon destroyed by a burst of white light emanating from Dawn Granger.
In 2011, "The New 52" rebooted the DC universe. Phantasm is among the many subjects kept under A.R.G.U.S.'s control.

Planned return.
During Jay Faerber's run on "The Titans", one of his plans for new series villain Epsilon was that he was to be a resurrected Danny given new life by Tempest's evil uncle Slizzath as part of a planned storyline. However, new editor Andrew Helfer overturned this and a new origin was given instead.
