This series details the covert operations of the modern, Post-"Crisis" Squad, created (in-universe) and directed by Amanda Waller. It is notable for bringing obscure characters such as Captain Boomerang and Deadshot to prominence; the latter received his own tie-in miniseries in 1988, co-written by Ostrander and Kim Yale. The Suicide Squad also presents a modern context for field team leader Rick Flag Jr.'s modern-day activities and his involvement in the Silver-Age Suicide Squad. Former Batgirl Barbara Gordon makes her first appearance as the information-broker Oracle, and serves as the Squad's remote radio support, a vocation she adopted after being shot by the Joker. She uses a wheelchair as a result of being shot.
