A red-eyed robotic Cyclops, Oculous is the sharp shooter of the Ten Terrors and is known as the "Cunning Hunter". He used a sniper rifle with a bayonette as his weapon. When Necrolai first entered the lower sanctum where the Ten Terrors dwelled, he was on the verge of firing on her with his sniper rifle, calling her an "eye sore", before Gekkor intervened. He possesses the power to demolecularise whatever he shoots at and can access another dimension from which he can fire at any target he wants wherever it is.
After Magma was destroyed, he became the second Terror chosen by the Stone of Judgement to challenge the Rangers, offering to spare their lives if they sacrificed Nick, The Light. The Rangersrefused and attempted to escape, but Oculous easily took out Vida, Madison, Xander, and Chipfrom his other dimension, leaving Nick wounded and desperate. When Phineas told Nick to look into his "heart", Nick summoned Fire Heart and combined with him, summoning the Mystic Battlizer and becoming the Red Dragon Fire Ranger. Nick defeated numerous Hidiacs & Styxoids before firing at Oculous, destroying him, and making his friends rematerialize.
