Did You Know?


When Clark goes through Bart's fake IDs he lists off the names Jay Garrick, Barry Allen, and Wally West. These are the names of the three characters in the DC universe who posses the ability to tap into the "Speed Force", each therefore respectively donning the identity "The Flash". Jay Garrick is the original Flash (1940-1955), and is now a member of the Justice Society of America. Barry Allen (1956-86) took over the role of The Flash in 1956 and is known as the Silver Age Flash. Lastly, his nephew Wally West (1987-2006) took over the role of Flash upon Allen's death, and is best known for his role in the Justice League Unlimited cartoons. Wally West is, incidentally, voiced by Michael Rosenbaum who plays Lex Luthor in Smallville. Most recently, Bart Allen (2006 - Present) took over the role of Flash, but this occurred after the episode "Run" was created which is likely why the name did not appear among the fake IDs.

A Fast Episode
17 August 2006 | by See all my reviews

This episode features a super-powered teen named Bart Allen. Although he is not given a super hero name nor is his family mentioned specifically, he is closely tied to the comic book character of Impulse. For those of you who are not familiar with this character, he is the original Flash's grandson from the comics.

In the comics Barry Allen's grandchild's name is Bart. So Bart Allen, but in the comics Bart inherited his powers from his grandfather. So judging from his age and his powers, we can assume that this is Impulse.

Hopefully we'll see more of this character. In the comics this character in now 20 something and might become the new Flash.
