He has since been featured as the lead character in Impulse (1995–2002) and The Flash: The Fastest Man Alive (2006–2007).

In addition to the Teen Titans and Young Justice, Bart was a core character in 10 issues of Justice League of America under the mantle of the Flash.

The Teen Titans are a superhero team appearing in American comic books published by DC Comics, frequently in eponymous monthly series. As the group's name indicates, the members are teenage superheroes, many of whom have acted as sidekicks to DC's premier superheroes in the Justice League. The original team later becomes known as the Titans when the members age out of their teenage years, while the Teen Titans name is continued by subsequent generations of young heroes. First appearing in 1964 in The Brave and the Bold #54, the team was formed by Kid Flash, Robin, and Aqualad (Garth) before adopting the name Teen Titans in issue 60 with the addition of Wonder Girl to their ranks.
