Note: Due to all ghost warriors being nearly identical in appearance, it is almost impossible to determine who is who in the television series. As such, any appearances of a ghost warrior will be cataloged here, regardless if they are in fact Cyrus.
During Morro's confrontation with the ninja in Ronin's pawn shop, he summoned several more Ghost Warriors to attack them. However, the ninja quickly obtained Aeroblades and defeated the ghosts with ease.
Finally free, the Ghost Warriors take over Stiix, turning all light sources green. The Ghosts revel in their victory, unaware the ninja are trying to get the Realm Crystal. When they see Nya in Lloyd's gi, the Ghosts try to stop them.
The Ghost Warriors fly around Stiix when the Preeminent is released. When the ninja took out the stilts, the Ghosts helped by making a shield of houses. They later dissolved in the Endless Sea after Nya unlocked her True Potential to drown their master.
Cyrus is a good fighter and a pretty sneaky ghost, but he doesn't really care if Morro wins or not. He's just doing all this to avoid being bored. If there are no ninja around to fight, Cyrus will pick fights with the other ghosts. Nobody likes him much, but he's too valuable in a battle for Morro to leave him behind.[link unavailable]
- Cyrus shares his name with Cyrus Borg, another character who acted as an antagonist (albeit unwillingly) alongside the main villain of the season that aired in the previous year. However, Cyrus the ghost was not named in the show.
- His appearance is identical to Cowler, Pyrrhus, and Ghurka.
- One of his tactics in battle is distracting the ninja by flying over their heads.
