Morticon

The general of the Morlock army, Morticon appears to be an undead cyborg, with the machinery that comprises the bulk of his body fused to what remains of his blue skin.

He is known to use a mystical portal to view the world and wields a sword called the "Fang of the Master".

He initially couldn't leave the Pit because Koragg's magic wasn't strong enough to free him, although he briefly broke through to the surface when Koragg robbed the Mystic Titans of their Megazord power and used it to free him. However, Nick quickly used a counter-spell to imprison Morticon once more.

Morticon has also been seen vanishing a Styxoid in thin air.

He was soon freed again to battle. With the the power of the Rangers, Catastros, The Gatekeper, and Udonna, they were all able to destroy Morticon. Koragg took his Fang Sword as his own.
