Nevar

Nevar is the primary antagonist in the BBC game show Raven from Series 2 onwards. His role in his debut series along with Series 3 at first was the role of evil guardian of the portal in the challenge The Last Stand (first variation) shooting lightning bolts from his left hand at warriors in an attempt to eliminate them during the challenge whilst he stood on top of the portal. From Series 4 onwards when he recieved his own staff of power (much like Raven by the start of Series 2, later revealed in Raven: The Island to have been stolen from the Enchanted Oak at the cost of half his life force every time he uses it), he could vanquish warriors in one hit although in the revamped Last Stand from said series up till 7, his aim only comes true when the losers are exposed. In Series 8 - 10's Last Stand, his aim is true only for the warriors to deflect his fire back at the demons until the loser's shield vanishes. Nevar can also summon Demons to do his bidding as shown in the Series 4 - 10 variations of the Last Stand.
