Silver Banshee was sent by Grodd to Skartaris along with Metallo to retrieve a large chunk of Kryptonite. They offered themselves as advisors for Deimos, the land's dictator. In the battle, Banshee used her sonic wail to kill some of Warlord's warriors, but was eventually thwarted by John Stewart. When he was briefly distracted, Banshee took the opportunity to make a run for it and return to the Legion's HQ.
Silver Banshee was present at the Legion's civil war, where she sided with Grodd's faction. Using her wail, Banshee almost killed Heatwave, but was foiled by Star Sapphire who killed her.
