Glitch Mordekaiser
This could very well be an Ultimate skin if this was taken.
Firstly, Mordekaiser's appearance is of that Arcade but more less so because he's a glitch in the programming and isn't supposed to exist in that respect. His armor is deep hue of green with particles flying off as he walks or stand. His weapon is an illustration of an overpowered weapon, or rather an Ultimate Weapon, riot's interception of this is up to them. He appears to be a bit incomplete in appearance.
Each time he kills an enemy unit, he erase them from existence much like Pulsefire Ezreal but instead of blue, it's green and minions disappears in an explosive death of particles.
His abilities will be a literal glitch in the LoL game.
Iron Man- His passive will rends the space around him to shred forming a weird shielding of black square holes floating up like an aura.
Mace of Spade - Each blow will distort the air around the target, increasing in "noise" with each strike for three times.
Harvesters of Sorrow - His allied champion that receive the buff becomes slight glitchy in the air around them much like Mordekaiser, growing more the closer they are to each other. The metal shards are game particles swirling around.
Siphon of Destruction - All enemy units hits loses some particles as they fly toward Mordekaiser enhancing his shields.
Children of Grave - New model of Dragon. Polygram looking dragon, its attacks are particle of green blocks wiping out some particles from enemy units it hit. Enemy champion hit by Children of Grave has green particles slowly drain from them upward. When they dies during the effect, they are rendered into unreadable error and the ghost emits game-ish glow aura.
On spawn. His body assembles from surrounding particles leaving him slight incomplete. On death, his body distort upward before finally exploding not unlike how Inhibitor explodes.
