Finally in print due to demand from readers, INFINITY INC. follows the adventures of the Justice Society of America's sons and daughters as they pick up the role of crime-fighters from their parents! Denied membership by the JSA due to a lack of experience, the younger cast of Infinity, Inc. decided to train themselves and included characters such as Power Girl, Huntress, Jade, Obsidian, Nuklon, and other characters who went on to greater prominence in the DC Universe. Uncover their humble beginnings in this collection of their first adventures from the early '80s! In this second INFINITY INC. collection, the mysterious Stream of Ruthlessness forces the members of Infinity Inc. to battle the Justice Society of America - while the Ultra-Humanite waits in the wings to destroy whichever team survives. This volume collects Infinity, Inc. #5-18 and Infinity Inc. Annual #1.
