Kell Mossa was the greatest scientist on his Earth until his experiments led to its unintentional destruction. The same experiments linked him to the entire Multiverse, and as a result, whenever a world is facing destruction, Praiah is unwillingly summoned to witness its death.

Pariah was driven insane by the terrible survivor's guilt he felt after the conclusion of the "Crisis on Infinite Earths," and Booster Gold was one of many heroes to oppose him when he attempted to manipulate the Great Darkness to recreate the original Multiverse with the help of an enslaved Dark Army including Angle Man, Felix Faust, Firefly, Golden Glider, Lion-Mane, Mirror Master, Rocket Red 1, and Scarecrow among many, many others.
