  • Influences for Mordekaiser include the Death Knight from World of Warcraft, the Shugoki and Lawbringer classes from For Honor, C.T. Fletcher, and Dwayne Johnson.[5][6][7]
  • Lorewise, Mordekaiser was moved away from the Shadow Isles because Riot felt necromancy and the undead should exist in the other regions of Runeterra.[8]
  • One of the scrapped visual directions that could have been taken with Mordekaiser include making him a miniature version of the Immortal Bastion; his shoulders would be like crenelated towers, his legs would be like walls, and his armor would be more architectural.[9][10]
  • Mordekaiser's visual goals were to combine the aesthetics of the Shadow Isles and ancient Noxus.[11]
  • Inside the Death Realm players were initially supposed to glimpse Mordekaiser's infinite and unknowable nature. This was later changed to a faceless hood and a magic crown, with the idea being to not be able to see his helmet and if you peered under his hood you'd go mad and dissolve into lifeforce.[12]
  • During development his armor could explode off, revealing the twisted black iron skeleton underneath.
  • Mordekaiser's title used to be 'the Master of Metal' and was going to be 'the Lord of Death' but after playerbase contention it was replaced with 'the Iron Revenant'.[13]
  • During development his Darkness Rise Darkness Rise was called Harvester of Sorrow, referencing his pre-work ability Harvester of Sorrow Harvester of Sorrow. His Obliterate Obliterate was called Nightfall. His Death's Grasp Death's Grasp was called Creeping Death or Master of Puppets, referencing Metallica. His Realm of Death Realm of Death was called Damnation, Shadow Realm, Spirit Realm or Death Realm.[14][15][16]
  • One of Mordekaiser's scrapped voice over lines involved asking Kled OriginalSquare Kled on their first encounter "What is... a taco? [17]
  • Scrapped Mordekaiser spells tested include:[18][19]
    • A version of his passive that would enslave the ghost of enemies if he scored a takedown on them.
    • A version of his passive where he would have very low attack speed but consecutive mace swings would increase his attack speed, basic attack range and evolve his mace into a flail.
    • A version of Obliterate Obliterate where his mace could turn into a flail and stick into the ground. Mordekaiser could then recast the ability and have a different effect based on where the mace head was relative to Mordekaiser.[20]
    • A version of Indestructible Indestructible where Mordekaiser would enter his wraith form and become untargetable but couldn't auto attack, similar toSenna OriginalSquare Senna's Curse of the Black Mist Curse of the Black Mist. During this time he would become weightless and float as if he suddenly weighed nothing, with the idea being that his manifestation in the physical world is transient.[21]
    • A version of Indestructible Indestructible where he would gain bonus resistances based on nearby enemies and gain slow immunity.
    • A spell that would fire a slow circular missile that would open a rift to the death realm.
    • A version of Realm of Death Realm of Death where Mordekaiser would create a portal around the target and himself, which, after a few seconds, would drag everyone to the death realm to fight.
    • A version of Realm of Death Realm of Death that would create two Dark Passage Dark Passage like objects at the locations where the target and Mordekaiser left to the death realm, that would allow other players to join the fight.
    • A version of Realm of Death Realm of Death that would fire a Fear Beyond Death Fear Beyond Death like missile that would send the target to the death realm.
    • A version of Realm of Death Realm of Death that would allow Mordekaiser to enter his spirit form and the first enemy who touches his spirit would be sent to the death realm.
    • A version of Realm of Death Realm of Death where the barrier around the death realm was a damage zone that would hit players with a strong damage over time if they tried to leave.
  • A Mordekaiser bug during development included one where someone would be permanently trapped in Realm of Death Realm of Death.[22]
  • During development some of Mordekaiser's abilities had AD ratios implemented. This was eventually scrapped due to having limited his item options significantly.[23]
  • At start Turret icon turrets didn't appear inside the Realm of Death Realm of Death. This was eventually changed due to lane opponents not being able to defend themselves when Mordekaiser was ahead.[24]

    • Morderkaiser was originally resurrected around 400 BN.
  • Mordekaiser defied death by sheer force of will because he refused to accept the reality around him. He gained necromantic powers by teaching himself Ochnun in the death realm, which allowed him to speak beyond the veil of death to deceive mortals into resurrecting him.[8]

  • The Hall of Bones in Sahn-Uzal/Mordekaiser's lore references Valhalla "Hall of the Slain" in Norse mythology;
  • However, much to his anger, the dead Sahn-Uzal ended up in an empty, foggy wasteland with other lost souls fading into oblivion;
    • This wasteland likely references Sheol, a dark realm where both the righteous and the wicked will go to after death, in Hebrew mythology.

  • Mordekaiser built the Immortal Bastion, a fortress which the capitol of Noxus is built around.
  • Given Sahn-Uzal (Mordekaiser when he was human)'s faith in the Hall of Bones, it's safe to say his culture did not have a Kindred OriginalSquare Kindred myth; which would explain why he was never claimed by them.
  • Mordekaiser tortured Veigar OriginalSquare Veigar, who would later mimic him after his downfall.
  • LeBlanc OriginalSquare LeBlanc was instrumental to his downfall.
