History
At some point before the early 21st century, the Veil planet was turned into a ball of ice by criminals, wiping out all but Androvax. He became a criminal who enslaved planets and sometimes destroyed them. This made him number one of the Judoons known enemy list. Androvax was eventually taken into custody by the Judoon.
