Psimon

Psimon was in collaboration with Bailyan government in studying extraterrestrial sphere that was sent from another world. Psimon was responsible for wiping the memories of Young Justice when they were on a mission to Bailya. When Psimon tried to erase Miss Martian's mind again they both end up in a mental battle. With help from Superboy after restoring his memories, Miss Martian manages to defeat Psimon and send him flying. Psimon later reports to the Light (Project Cadmus' Board of Directors) on his failure with the sphere and recapturing Superboy. They reveal however that the operation can be considered a success, given that the Light's newest partner has an operational delivery system, one that sent them the extraterrestrial sphere.
