Nechros starts of the duel by points his staff at his foe and firing a magic blast towards Hawk Moth, only for the butterfly to barely dodge it by moving his left shoulder back.
Nechros continues his onslaught of red magic towards Hawk Moth who begins to run across the room evading nechros's blasts. which nechros keep his eye on him tracking his movement while he launching his magic blasts, this results to the evil Ruler's red magic coming into contact some of the relics knocking them over,
disintegrating them or just destroying the pedestals the relics were on and one of them was heading for the butterfly and he sees it so he swings his cane towards the blast redirecting it back to nechros. The Masked ruler backhands the blast with ease with his silver armored gauntlet, using the blast as a distraction Hawk Moth opens his his purple suit to release hordes of akumas within it filling the room with purple butterflies and he extends his cane towards the emperor pointing to their target.
Hawk Moth: Fly away by evil akumas and evilize him!
The swarm of butterflies start to surround the emperor trapping within a vortex of negative energy, the ruler swings his staff launching a wave of magic towards group of butterflies however they dodge causing the magic to miss and hit a wall of the room, the butterflies reform into a the vortex with some hovering over the ruler like an eagle preparing to dive into their prey,
he attempts to blast another wave of magic only for the butterflies to dodge again making his attack miss and damage the room even more, a few butterflies approach him trying to akumatize the emperor once for him fire small blasts that kill the butterflies that approach him.
Suddenly Hawk Moth enters the vortex of butterflies behind the emperor by lunging himself through it, he swings his cane towards the ruler attempting to strike him with it but Emperor nechros manages to reacting to it turning around to block the attack with his staff, the butterfly swings his cane going on the offensive pushing the emperor back into the vortex of akumas with his experience in fencing and swordplay have the upperhand in the melee fight while nechros is on the defensive blocking hawkmoth's cane strikes while blasting away near akuma that goes near him.
Nechros being corner he is annoyed and extends his hand which a rock spike emerges from the ground catching hawk moth off guard and launched him away pushing him out of the vortex.
Emperor nechros: Enough of this.
Nechros his staff in the air with omits a bright red light which then flashes creates a massive pulse of magic destroying the vortex of butterflies and freeing himself from the negative charged cage. The Emperor hold up his left hand and holds up his pointer finger and a red orb glows on the tip of it which cause Hawk Moth who tries to get back up from the stone attack suddenly glow red and gets dragged to have a face to face with nechros himself.
Emperor nechros: My turn.
Nechros swings his staff towards the fashion designer which fires a point-blank magic blast sending Hawk Moth through the stone gate and dropping his cane,
Hawk Moth tries to get up but suddenly fleshly arms rise up from the ground and grabs his arms and legs immobilizing him. The emperor walks out of the room staring down at the immobile butterfly
Emperor nechros: What's wrong little butterfly? Have your wings already been clipped?
As he was mocking his foe he notices someone watching them, he looks to the side and it seems to be a castle tour with nechros's assistant Kikimora who witnesses Hawk Moth's appearance from the relic room,
Emperor nechros: I'm just dealing with an intruder personally.
Emperor nechros raises his staff and a beam of red magic fires onto Gabriel's head causing him immense pain which he grunts and yells which allows nechros to see who is behind the mask, he's surprised to learn his foe is actually a grown human but continues his glare onto his foe.
As nechros continues to torture the butterfly with the class and his assistant,however he uses turtles miraculous.
Hawk Moth:shelter.
Emperor nechros: what the.
Hawk moth managed to break free from the flesh arms holding out his left hand which cause the cane to come to it, he grabs the top with his right hand and pulls it out revealing a sword within the cane and he swiftly slashes nechros in the mask following it up with a kick in his stomach launching him away, He immediately puts his sword back into his cane as he will do a special transformation quickly.
Hawk Moth: Duusu, Nooroo Unify!
With a flash of blinding light, Gabriel Agreste's spell begins to unifying of the Peacock and the Butterfly Miraculouses transforming from his purple suit into Shadow moth form from earlier wielding a fan and a cane. He puts his cane under his left arm and he pulls out a feather and fills it with negative energy turning it blue, he tosses it into the air and grabs his cane from his under arm and raises it to the air letting the amok land on it.
Shadow Moth: Come here my amok and bring my creation to LIFE!
As the feather lands on the cane and bluish energy appear above Shadow Moth which soon forms into a butterfly monster that proceeds to flap its wings creating massive gusts of wind that blows the dust around them to cover the area blinding them.
When the dust clears its reveals several giant holes leading to the outside of the castle with Hawk Moth while Emperor nechros pants from surprise strike from earlier with some liquid ooze dripping from his sockets. Nechros faces the class who are in fear of what they witnessed, it's revealed to have his mask chipped in a shape of a sword slash,
Kikimora: Sire, are you ok?
Emperor nechros looks at his servant and pats her head assuring her he's alright.
Emperor nechros: Worry not kiki, I am alright.. Summon the shadow coven heads,the homunculus and the platinum Guard. It appears that I require aid to defeat this foe, can I trust you on that?
Kikimora: Oh course sire, I'll get to it right away, this way students.
Kikimora guides the class out of the castle leaving the evil emperor alone. Nechros walks through the holes the butterfly made and sees Hawkmoth on his butterfly hovering above the bridge with several of his guards laying unconsciously unable to move around them with nechros teleports to the bridge to confront his foe.
Emperor nechros: Clever tricks, human but this has gone far enough.
Shadow Moth: Oh on the contrary your majesty, this battle has just begun, and by the way, the name's Shadow Moth now.
