Quislet was an energy being from the other dimensional world of Teall. His people lives as hive beings, but Quislet enjoyed his individuality, so when he was made pilot of the new Trans-D Vessel his people had created to explore reality, he stole the vessel and took it to Earth. Quislet's native power, to inhabit and animate almost any object (although the inhabited object disintegrated after a short time), made him eligible to join the Legion of Super-Heroes, so he applied and was successful.
Quislet had a short career with the Legion. Eventually, his people tracked him down and brought him back to Teall to be tried for his crime. Wildfire - probably the only Legionnaire who could exist in Teall - accompanied him, and helped him escape his people's wrath. However, the Trans-D Vessel was destroyed on a later mission, and leaving Quislet with no way to exist on Earth, so he had to return to Teall, and his final fate is unknown.
