Home of the long-lived adventurous Science Hero Tom Strong, mystical champion Promethea, screwball 'heroes' The First American and Splash Brigannan, Indigo City defenders Cobweb and Greyshirt, prepubescent ultra-genius Jack B. Quick, and police officers Toybox and Smax, among others.
- Earth-ABC is part of a larger Multiverse itself, including the various alternate reality precincts collaborating with the main ABC universes' Precinct 10 (colloquially known as Top Ten), a more traditionally superheroic universe designated Earth A home to Tom and Tesla Terrific (itself with an evil counterpart reality known as Earth B with Tiberius "Black Tom" Strong and Twyla Strong), a universe where the Aztek empire survived to become Multiversal conquerors, and a universe of anthropomorphic animals and inanimate objects operating on different laws of physics defended by the rabbit Warren Strong. The main ABC universe has been referred to by some other universes as both Earth-2058 and Earth-C.
- Earth-ABC's super-powered champions are referred to as Science Heroes, rather than super-heroes.
- The amazing parallel world of Terra Obscura is located in the same universe as Earth-ABC, but on the other side of the Milky Way Galaxy. It is inhabited by the Science-Heroes of SMASH.
- After World War II, the vast majority of Earth-ABC's science heroes were relocated to the city of Neopolis, as their rapidly growing rogues galleries and supporting casts became too much for society at large to handle; only select teams such as America's Best continued regular operation.
- In the wake of the restructuring of the Multiverse, Earth-ABC is now re-labeled 25. It is opposite Earth 31.
