Darkness was the first Dark Being to be created. He used to be a Makuta until he was killed in battle by a Toa. Darkness came back to life when a ghost entered his dead body and fused to it. After he was revived his power was multiplied by 1000-fold giving him the ability to revive any thing dead and make it a lot stronger than before. with these new abilities he built his army and started his rein of terror.
