Bartholomew Henry "Bart" Allen II is a superhero appearing in American comic books published by DC Comics. A speedster, he first appeared under the alias Impulse and later became the second Kid Flash and the fourth Flash. Created by Mark Waid and Mike Wieringo, Bart first made a cameo in The Flash (vol. 2) #91 in 1994 before his full debut in issue #92.{{cite web |last1=Markstein |first1=Don |title=Impulse |url=http://www.toonopedia.com/impulse.htm |access-date=April 2, 2020 |website=Don Markstein's Toonopedia}} He has since been featured as the lead character in Impulse (1995–2002) and The Flash: The Fastest Man Alive (2006–2007). Bart also appears in the series Young Justice and Teen Titans as a member of both superhero teams.{{Cite book | last = Jimenez | first = Phil | author-link = Phil Jimenez | contribution = The Flash | editor-last = Dougall | editor-first = Alastair | title = The DC Comics Encyclopedia | pages = 124–127 | publisher = Dorling Kindersley | place = New York | year = 2008 | isbn = 978-0-7566-4119-1 | oclc = 213309017}}

As first conceived by writers, Bart was born in the 30th century to Meloni Thawne and Don Allen, and is part of a complex family tree of superheroes and supervillains. His father, Don, is one of the Tornado Twins and his paternal grandfather is Barry Allen, the second Flash. His paternal grandmother, Iris West, is also the adoptive aunt of the third Flash, Wally West (Bart's first cousin once removed). Additionally, Bart is the first cousin of XS, a Legionnaire and daughter of Dawn Allen. On his mother's side, he is a descendant of supervillains Professor Zoom and Cobalt Blue as well as the half-brother of Owen Mercer, the second Captain Boomerang. In addition to these relatives, he had a supervillain clone known as Inertia.

For most of his superhero career, Bart was the teenage sidekick to Wally West. After West's apparent death in the Infinite Crisis crossover event in 2006, Allen grew up and became the Flash. His tenure as the Flash was brief and concluded with his death in issue 13 of The Flash: The Fastest Man Alive. Allen was subsequently absent for nearly two years after his apparent death, but resurfaced—young again—as Kid Flash, in 2009's Final Crisis: Legion of 3 Worlds. During DC's The New 52 era, Bart Allen was reintroduced in Teen Titans as the alias of an amnesiac revolutionary from the future named Bar Torr; the character was later written out of comics, and his tenure erased from continuity by the subsequent DC Rebirth initiative. The original Bart Allen was brought back as part of DC Rebirth's Wonder Comics Young Justice series.

Outside of comics, Bart has been portrayed by Kyle Gallner in the live-action television series Smallville. Jason Marsden voiced the character in the animated series Young Justice. Jordan Fisher portrays a variation of the character as the future son of Barry Allen and Iris West-Allen starting in the seventh season of The CW Arrowverse television series The Flash as a recurring character.

Powers and abilities

Bart's primary power is speed, along with abilities that are common to comics speedsters, such as creating whirlwinds, running on water, and vibrating through matter. The latter ability results in "molecular taffy" if Bart does not concentrate; he also possesses an aura, that prevents air friction while running. Bart does possess some abilities that other speedsters do not have. He has the ability to produce "scouts", Speed Force avatars that he can send through the timestream, but has used it infrequently.Impulse #75 (August 2001) Bart has also displayed the ability to create powerful radio waves by rotating his arms at high speeds and using the resulting vibrations in conjunction with his teammate Static's electromagnetic abilities.Teen Titans (vol. 3) #84 (August 2010)

After Infinite Crisis, Bart's connection to the Speed Force is more difficult to control because he now contains the Speed Force and, in essence, is the Speed Force. When he taps into the Speed Force, Bart appears to have electricity crackling around him, and the Speed Force inside him becomes so lethal that he initially wears the Flash suit while running to prevent it from killing him.Flash: The Fastest Man Alive #3 (October 2006) After remembering his experiences on an alternate Earth during a fight with Griffin, he began to gain a measure of control over the Speed Force before it was released from his body just prior to his death.
