"Send Mirage of Nightmare to the Graveyard, and recover 1000 Life Points!"
[Supreme King, LP 2200 → LP 3200]
"As expected, the same old trick," Kira smiled.
The Breaker the Magical Warrior's sword once again cut through empty air. It seemed fruitless, but Kira was already satisfied. The Breaker the Magical Warrior's effect was meant to remove that face-down backrow threat. Even though it whiffed, it confirmed the set card was indeed reactive. With the backrow threat identified, his mission was essentially accomplished.
"Ritual Spell: 'Super Soldier Ritual'!"
Kira raised the Spell in his hand.
"Tribute monsters from my hand and field whose total Levels equal eight to Ritual Summon the 'Black Luster Soldier' Ritual Monster from my hand!"
He revealed a monster from his hand.
"By banishing 'Breaker the Magical Warrior' from the field and 'Beginning Knight' from my hand, I conduct a Ritual Summon!
One soul guides Light, one soul guides Darkness—now the Gate of Chaos opens. The legendary warrior—
—Black Luster Soldier, appear!"
Souls of Light and Darkness dissipated within a chaotic tempest. A pillar of chaotic radiance, as if from beyond the heavens, descended; in that vortex landed the mightiest warrior!
[Black Luster Soldier, ATK 3000]
The Supreme King's golden eyes flickered. "This spirit…"
He seemed to sense something extraordinary from Black Luster Soldier—something ordinary Duel Spirits lacked.
"Even so, its ATK still can't defeat my current Malicious Edge," the Supreme King said.
"When Beginning Knight is used as Ritual material, Black Luster Soldier gains an additional effect," Kira said. "Once per turn, banish 1 monster your opponent controls. Banish Malicious Edge directly!
Dimensional Slash—Open the Rift!"
The chaotic blade cleaved, a swordstroke that warped space itself. Even the repeatedly empowered Malicious Edge was helpless before the fissure in dimensions, letting out a scream as it was sucked away.
Also, the banish effect conferred by Beginning Knight does not impose the attack restriction. He can still attack this turn.
"With that, Vicious Claw can't protect your Malicious Edge. Destroy both 'Power Frame' and 'Vicious Claw' equipped to it."
Kira swept his hand.
"Black Luster Soldier, direct attack on the Supreme King."
The dimensional slash cleared the field. The Soldier's blade hewed straight toward the Supreme King. With nothing left to bar the way, that domineering aura seemed poised to cleave heaven and earth, surging over the otherworldly monarch like a flood.
[Supreme King, LP 3200 → LP 200]
Brought to a flickering candle by a single stroke, the Supreme King merely lowered his head, his face shrouded in shadow, unreadable.
Kira: "Set two cards. Turn end."
Several seconds of silence. The Supreme King kept his head down, unresponsive for a moment.
After a few seconds, he slowly raised his hand.
"…Draw."
He looked up; the golden eyes seemed even more terrifying than before, as if golden flames burned within them.
"I underestimated you, warrior from another world," he said coolly. "From now on, I'll show my true power."
"Oh?" Kira said. "Meaning the Supreme King hasn't even been serious up to now?"
The Supreme King didn't answer. He responded silently with the cards in his hand.
"The effect of 'Evil HERO Adusted Gold' in my hand. I discard this card to add 1 card that lists 'Dark Fusion' in its text from my Deck to my hand."
It was clearly a darkened variant of Elemental HERO Captain Gold."
The Supreme King revealed the card he searched.
"I add the Spell 'Dark Calling' to my hand," he said, raising his voice.
"I activate the Spell 'Dark Calling.'
Banish Fusion Materials from my hand and Graveyard to perform a Dark Fusion of a Fiend-Type Fusion Monster."
He pulled two cards from his Graveyard.
"From my Graveyard, I banish 'Evil HERO Adusted Gold' and 'Evil HERO Wild Cyclone'!
The Fusion requirement is 'Evil HERO' + any Level 5 or higher monster. Descend, my strongest Evil HERO, the embodiment of the Dark HERO, whose power shall flatten all dimensions—
—Evil HERO Malicious Bane, appear!"
A fearsome power—like the Supreme King's vast darkness made manifest—took the form of the mightiest Dark HERO and descended!
[Evil HERO Malicious Bane, ATK 3000]
"Malicious Bane cannot be destroyed by any form of destruction!" the Supreme King barked. "And Malicious Bane's effect: once per turn, destroy all monsters your opponent controls with ATK less than or equal to this card's ATK!"
The Supreme King gave a harsh command.
"Ultimate Annihilation!"
Malicious Bane roared. Boundless darkness surged like a tsunami. Even Black Luster Soldier could not withstand it, crushed under that terrifying flood.
"And Malicious Bane gains ATK equal to 200 times the number of destroyed monsters!"
[Evil HERO Malicious Bane, ATK 3000 → 3200]
"So you even brought out Malicious Bane," Kira narrowed his eyes. "As expected of the Supreme King."
"Then I activate a set card, the Trap 'Puzzle Reborn,'" Kira said. "When exactly 1 of your monsters is destroyed by a card effect, Special Summon that monster back in Defense Position.
Revive Black Luster Soldier in Defense!"
[Black Luster Soldier, DEF 2500]
"You think that's enough to defend? Far from it. This turn I'll show you true darkness," the Supreme King snapped.
"Next I activate the Spell 'Dark Fusion'! I fuse 'Valkyrion the Magna Warrior' in my hand with another 'Evil HERO Malicious Edge'!
Fusion requirement: Fiend-Type + Rock-Type. Dark Fusion Summon—
—Evil HERO Dark Gaia!!!"
[Evil HERO Dark Gaia, ATK ?]
"Dark Gaia's ATK equals the combined original ATK of the Fusion Materials!" the Supreme King stated.
[Valkyrion the Magna Warrior, ATK 3500]
[Evil HERO Malicious Edge, ATK 2600]
"Therefore, Dark Gaia's ATK is…"
[Evil HERO Dark Gaia, ATK 6100]
"Six thousand one hundred ATK," Kira nodded gravely. "Terrifying."
But the Supreme King continued: "I activate 'Dark Calling' once more!
From my Graveyard, I banish 'Evil HERO Malicious Edge' and 'Evil HERO Lightning Golem'!
Fusion requirement: 'Evil HERO Malicious Edge' + a Level 6 or higher Fiend. Dark Fusion—
—Evil HERO Malicious Fiend, appear!!!"
[Evil HERO Malicious Fiend, ATK 3500]
