Immortus (Nathaniel Richards) is a fictional character appearing in American comic books published by Marvel Comics. He is the future (and later, alternate) self of Kang the Conqueror.
Immortus first appeared in Avengers #10 and was created by Stan Lee and Jack Kirby.
At some point in his personal timeline, Kang became weary of battle due to frustration and the loss of his son Marcus and consort Ravonna in several timelines. He was approached by the alien Time-Keepers — time travelers from the end of the universe, the last living creatures in existence — to become their agent, preserving timelines rather than conquering them in exchange for immortality. He accepted and reinvented himself again, this time as Immortus, the lord of the other-dimensional realm of Limbo.
He again came into conflict with the Avengers, but under different circumstances. In his first encounter with the Avengers as Immortus, he attempted the destruction of the Avengers through the use of mythological figures as combatants after trying to join the Masters of Evil, but being told by Baron Zemo he has to defeat one of the Avengers. The Masters attacked the Avengers after Captain America had been taken to 1760 the Tower of London where Rick Jones was imprisoned. But when he rescued Rick he was returned to his own time and with his help the Masters were defeated at a near-win. This event was apparently erased after the Enchantress turns back time to prevent the Avengers capturing the Masters. He was partially responsible for the creation of the Vision, allegedly creating a temporal copy of the original Human Torch that the android Ultron used to create the Vision.
I'm falling deep in Sphere beyond
In bloodred Nights I make my Way
I am fading away from this Life
Alone I'm standing, God has lied to me
My Soul is not sleeping, I'm finding no Peace
I will rise against you all and your Fear is my Pride
Alone I stand beneath the Gates, to destroy Heaven to destroy the Light
As the Fire burns around me and I laugh as the Angels die
Now their Wings have turned to Ash and my Eyes are burning bright
I'm full of Hate, I'm full of Blood
I slay the Christians and enslave their Souls
Now I - I know who I am
I'm the chosen one from Hell
I have slaughtered the holy ones
I am the Rebirth of the Night, I'm the chosen one from Hell
I'm the one who controls your Fear, mightier than Death
