Omen was unlocked offscreen by scanning a Mothman in "The Mothman's Prophecy"

Omen is used offscreen to instill fear into the Null Void inhabitants in Null and Voided over many months.

Omen physically debuts in Secret of the Skin Walker: Where he flees Ben and Kai Green after telling them where to find Yenaldooshi.

In Ben Goes Evil: Omen is used to escape Waybig's grasp. He is then informed by "The Prophecy" that this is actually Albedo. Once Albedo confirms this by peeling off a green decal he placed on his Ultimatrix and turns Ultimate, Omen is squashed into the ground like a bug.

He is used offscreen in Undertown Mystery to hypnotize Rojo in a dark alleyway into being complicit since she tried to scam Ghost King out of more money than her services were worth. Only his eyes are seen due to the alley's darkness.

He is used in War of the Villains to flee from the Plumbers when they finally arrive to break up the warring villains.

In House Pest: He mind controls Subdora after she attempts to do Ghost King in, making her his spy within the new Negative 10.

In Bad Jersey, Good Devil: He chases after J.D., only to be defeated quickly for underestimating his strength.

In The Sasquatch Factor: He terrorizes Bigfoot hunters offscreen. He later flies off into the night after Bigfoot is safe.

Omen appears in "Movie Set of Horrors" where he is shown off to the Director. He was later used offscreen to help film the horror movie.
