Omen is the first Radiant to join the VALORANT Protocol, and has a mysterious and dark past that is intertwined with Viper's. The central focus of Omen's character is an unknown event or accident that occurred in his past, resulting in him being 'ripped apart', and transformed from a human into his current state.

Omen’s entire body is cloaked and covered by a Purple Cloak, a Mask and Multiple Armor Pieces and Clothes. So his visual appearance is unknown.
