The Multiverse is filled not only with counterparts between parallel planets but even within subsequent generations on their same world. Prime examples are the Teen Titans and Infinity, Inc. and their forefathers and mothers of the Justice League and Justice Society of Earths One and Two.
From Robin and Huntress copying the caped crusaders the Batmen, to Wonder Girl and Fury influenced by the Wonder Women, to Golden Eagle and Northwind inspired by the Hawkmen. While not matching the originals, the younger generation harnessed the same heroism exemplified by their mentors. And as teams, the teens bonded in a manner that the originals never could, as their individual legends were enhanced by their reputation as titanic teen teams.
Although the Earth-Two teens... Infinity, Inc... appeared later as a group than had Earth-One's Teen Titans, their forebearers in a sense was Little Boy Blue and his Blue Boys team which operated decades before the Titans had. And that's not even considering their Robin, Speedy and other teens like Sandy the Golden Boy and Dyna-Mite as well as Star-Spangled Kid and Wing... all members of the All-Star Squadron during World War II. The silver age Robin and Speedy as well as their compatriots were more residents in the groovy sixties (or later, considering that world's sliding time scale). Nevertheless, these teams were timeless in nature, capturing the enthusiasm of youth.
