Fan Casting Atomic Knight in Return to the DC Universe

A proud military man in Platoon 13, Sgt. Gardner Grayle underwent a virtual reality experiment where he would find a way to react to a world after atomic war, due to his feverishly opposing it. After emerging from the experiment, Gardner would don a S.T.A.R. Labs battle suit and serve with the Seven Soldiers of Victory as the second Shining Knight. Later on, after working for S.T.A.R. Labs, with an atomic suit, Gardner would call himself the Atomic Knight. Now, in present day, Gardner leads a band of actual Atomic Knights in Blüdhaven, guarding it and aiding with the nuclear damage of the Secret Society dropping Chemo on it... to hope it can be able to become livable again.
