Mortuus

Victus Mortuus is a Darkspawn monster of Equestria who is so feared by pony kind, it is expressly forbidden to say his name just as much as it is to Pitch Black. He was long imprisoned in a mountain called Mount Ragnarök, which was so strongly put together that nobody in the entire universe could free him, and the only thing that could do so was power on par with Darkspawn. Mortuus is a deadly destroyer of lands and has existed during the days of the Alicorn Gods, and fought against them during the AUU First Cartoonian War. He shows no remorse in what he does, as he is among the Darkspawns' best creations. He was defeated by the Alicorn Gods using power that can only be generated by all Alicorns combined, and it is the only way he can be beaten, and since the death of the Alicorn Gods, it was a solemn duty to prevent the mountain from being destroyed and releasing what is essentially Equestria's strongest and unstoppable threat. Almost released by Grogar and failing, he has swore that one day, he would return, and begin the Catalysm. Described as an 'ungodly corruption', Victus Mortuus is a demonic entity of incredible power, and the personification of what Equestria would be without Gods: a cataclysmic wasteland with nothing to stop him. He had the job as the head of the Equestrian underworld before Death Coffin, and is even the secret creator of the Jewel of Souls, aiding lost spirits find peace in the afterlife, as well as help the old and sick find acceptance into death, effectively serving as Equestria's first grim reaper. Though this peaceful exchange between Equestria and the Hell beneath it would not last forever. Each soul he helped ferry into the afterlife granted him a burst of power, and soon Mortuus would feel an insatiable appetite for more, causing disasters such as volcanic eruptions and earthquakes just to increase the death toll and thus fuel more spirits into his hellish home. The Alicorns would finally learn of Mortuus' growing hunger and soon attempted to have him evicted from his position and silenced into the sun, never to return to Equestria, but he was able to prepare for their interference, and eventually fully-embraced the power of their Darkspawn enemies after secretly being a pawn to Chernabog. Equestria became a broken country as a result, continents shattered and scattered, oceans burning and devoid of life, soon the land became the same hell he once called home. He was soon challenged by the Alicorn Gods for control, and was defeated thanks to his anger growing out of control as they used it to distract him for a combined energy of the will of all the Alicorns in Equestria. Mortuus was shackled into a prison far stronger than the Sun or Tartarus: the deep hellish prison and the Bald Mountain of Equestria, Mount Ragnarök, doomed to never be released, only being released by Darkspawn, and since they were all locked away, they made good on that promise, while Death Coffin would take his place as head of the Equestrian Underworld. Mortuus draws his power from the very soul and heart of the Hell he came from, fusing the searing heat with his pure brute strength for his purposes. He believes in the power of corruption, capable of transforming mortals into lesser demons with no possible method to return to normal aside death. He speaks with a deep voice with deeper echoes following, speaking in an old accent similar to the Darkspawns and Alicorn Gods, having a voice on par with Michael McConnohie. His brutality appears to be his defining trait, as he wasted no time in flat out bludgeoning the Alicorn Gods a good bit before making the final move to destroy them. He is undoubtedly physically strong, and with his power of corruption, he is a near-invincible enemy. There is no limit to his corrupting power, as even the purest of hearts will become the most bloodthirsty of murderers at his whim. The horror comes with the knowledge that there is no cure for it at all, and that the victim is doomed from the start. His mere presence is felt with a searing heat. The only thing that can stop him is the combined effort of all Gods in Equestria.
