History
The Avant Guard were the personal enforcers of Opal Luna Saturnyne of the Dimensional Development Court, and assisted her in trying to accelerate the development of the retrograde Earth-238. They resembled businessmen in bowler hats and carried umbrellas which were actually highly advanced weapons capable of firing energy beams, causing dimensional rifts or regressing life forms to an earlier evolutionary stage.[1]
When Saturnyne was placed on trial by the DCC for her failure on Earth-238, members of the Avant Guard were forced to testify against her.[2]
