- Not to be confused with Cyrus Borg.
Ghost Warrior Cyrus is a ghost from the Cursed Realm. Despite being a skilled fighter and a sneaky and irritating adversary, Cyrus, like many other prisoners of the Cursed Realm, doesn't really care if Morro wins or not. He's just doing all this to avoid being bored, especially since he has suffered so many years of confinement.
If there aren't any Ninja or people around to fight, Cyrus will pick fights with other ghosts to keep himself occupied in his new environment. Nobody likes him very much, but like many other ghosts, he's too valuable in a battle for Morro to leave out of the action.
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 boss.
- Cyrus shares his name with Cyrus Borg, another character who acted as an antagonist (albeit unwillingly) alongside the main villain of a prior year. Likewise, the two of them are the only characters to share identical names.
- His appearance is identical to Cowler and Ghurka.
- The only reason he works for Morro is that he is bored and has nothing else to do.
