Hal Jordan made one brief appearance in Justice League Unlimited during the episode Once and Future thing Part two: Time Warped. Where due to one of the fluctuations in the unstable time stream created by Chronos he replaced John Stewart. His ring brought hi up to speed on what was happening and he was able to convince Enid Clinton to help them find her husband and fix the timeline. The time stream fluctuated again returning John Stewart to the team to which Static said "Just make up your mind already!"
