Impulse #51 is an issue of the series Impulse (Volume 1) with a cover date of August, 1999.
Synopsis for "It's All Relative"
A mysterious stranger is still observing Impulse and his super computer named Craydl even speaks about an obsession regarding Bart Allen. And oftentimes the hooded figure is perplexed by Bart's success as a super hero despite his impulsive behavior.
Bart is in school and his friends are astonished that he does not read the comic "The After-Life Avenger". As they talk about the comic, they raise Bart's interest and he reads the entire collection in a heartbeat. He notices that #16, a rare exemplar, is missing and Bart does not understand how one is able to wait 30 days until the story continues.
Later while driving home, Carol brings up Preston's upcoming birthday and Bart thinks that the missing issue of the comic book series would be a perfect gift for Preston. But he has to run all the way to Seattle to find issue #16. When running back, Impulse runs into a teenager named Nelson who invented a device that surrounds him in swirling fog and he used it to stop a truck loaded with action figures from the After-Life Avenger series. Bart finds out that Nelson is the son of the The Silver Fog. And as the Flash defeated the Silver Fog, now Impulse defeats Nelson.
All this was watched by the hooded figure who now reveals him to the last of the Thawne family. He calls himself Inertia and looks to replace Impulse ...
