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 possesses Herculean strength, able to hurl the Mystic Dragon (with the Mystic Phoenix riding it) with one arm with relative ease and because of his strength and skill in battle, especially with his sword, he considers himself to be the Most Powerful Warrior of All Time.
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 had a very short temper, desperately wanted out of the Underworld and frequently attacked Koragg to get him out.
Morticon has also been seen vanishing a Styxoid in thin air. He can also be very intimidating to Necrolai. He and Korrag never got along, and have gotten into fights on two occasions.
Morticon was soon freed again to battle. He proved very powerful and was once again in his giant form when he appeared, easily defeating the Titan Megazord uses his own form of the Dark Magic Strike. He batted away the Mystic Dragon with his sword while Nick went to rescue Clare. Morticon was eventually defeated when the Mystic Rangers formed the Titan Megazord and, with the help of Udonna, destroyed him. All that remained after that was his sword, which Koragg found and claimed for himself.
