Synopsis for "Supergirl: The Fastest Women Alive"
Supergirl and Jesse Quick are racing around the world for a special charity event sponsored by "Snickers". As the announcer enumerates the rules (such as not flying) Superman and the Flash are in the stands watching proudly.
Kara and Jesse rush off. They race neck and neck across the Atlantic Ocean, Africa, China, the Pacific Ocean... helping people along the way before heading back into the stadium.
When they return to the building they find the Parasite waiting for them. He has already drained everyone in the stadium, including Superman and Flash. Both heroines engage him, but taking him down proves to be a tough task.
Then Jesse notices a man who ate a Snickers and regained his strength. Kara and Jesse have an idea and instruct the man to hand out Snickers to the crowd. Supergirl, Jesse, Superman and Flash battle the Parasite and shove him into a hole. Then the group dogpiles him.
Once the Parasite is captured, Kara and Jesse sprint to the finish line.

Notes
- The comic cannot fit into either the New Earth or Prime Earth continuity, as A.R.G.U.S. didn't exist on New Earth, while Jesse has only been shown in a vision of the Flash Family, and as a ghost in Barry Allen's mind and never known to exist in the reality. She was restored by Dr. Manhattan in Doomsday Clock (Volume 1) as part of JSA under her Liberty Belle identity, however the changes made by the comic didn't translate exactly into the main timeline.
- The indicia for this issue does not include an issue number even though it is the second one-shot in the series.
Trivia
- The final panel is a homage to the cover of Superman #199, Limited Collectors' Edition #C-48 which was also referenced by Tiny Titans #16.
