Malcolm Thawne is a character appearing in American comic books published by
DC Comics as
Cobalt Blue, an enemy of
the Flash. The character was created by
Mark Waid and
Brian Augustyn, and first appeared in
Speed Force #1 (November 1997). He is the twin brother of
Barry Allen, an enemy of
Wally West, and a distant ancestor of
Eobard Thawne. Malcolm was raised as the son of
con artists (Hugo Thawne and Charlene Thawne) who lure unsuspecting victims. He learned in
Central City that he's actually
Henry Allen's and
Nora Allen's other son who
Asa Gilmore used to cover Hugo's and Charlene's true child's accidental killing, resulting in him tracking down and murdering the doctor in a rage. His grandmother helped train him as he was fueled by rage and jealousy to utilize the Blue Flame Talisman capable of stealing super-speed. His first attempt against Barry ended in failure, and he was absorbed into the Blue Flame Talisman, only to re-emerge years later after Barry's death during the "
Crisis on Infinite Earths" with Wally as a successor. Apparently having been cheated out of his dreams of revenge, Malcolm instead focused on his brother's descendants traveling through time in a bid to exterminate. His Cobalt Blue identity ignited a family feud that endured for a millennium. The feud came to a head in the late 30th century, where Barry was living with
Iris Allen and Wally arrived as protection. Various
speedsters (including
Jay Garrick, the
Tornado Twins, and
XS) are under the control of Thawne's spirit as each one carried a shard of the Blue Flame Talisman. After defeating the other speedsters, Thawne's menace ended with Wally overloading the Blue Flame Talisman with the
Speed Force's energy.
