"Mobilicorpus!"
Using a specialized spell to levitate the heavily injured Warrod, Goku sent him drifting toward a safe distance, ensuring Grandpa Dumbledore could easily recover him for treatment.
Immediately after, Goku's body began to expand rapidly, transforming into his ten-meter-tall Giant Form.
The mountain-toppling magical pressure radiating from Hades made it clear to Goku that without using Gigantification Magic, he might not actually be able to overcome this opponent.
This was the most powerful "Master" he had encountered since arriving in this world.
It was an opponent truly worthy of him betting everything on the fight.
Consequently, there was no trace of nervousness or fear on Goku's face—only the intense focus and pure joy of facing a top-tier warrior.
"Makarov truly raised a formidable brat. Fine then, let this old man see what you're made of!"
Hades didn't seem surprised by the transformation. With a sharp wave of his withered hand, he once again unleashed the forbidden technique that had just brought Warrod to his knees.
"Black Magic: Amaterasu Formula 100!"
With the "Devil's Heart" he had personally crafted aboard the airship serving as a limitless power source, Hades possessed an inexhaustible reservoir of magic. He could spam high-tier forbidden spells as easily as throwing a common punch.
Seven layers of pitch-black magic seals instantly enveloped Goku. A terrifying explosion rocked Tenrou Island once again, sending flames roaring into the sky.
However, this time, the result defied Hades' expectations.
"That's a really strong move! It actually hurt a little," Goku praised sincerely, lowering the arms he had used to shield his face.
Currently, Goku was under the dual empowerment of Total Concentration Breathing and Gigantification Magic, pushing his defensive capabilities to a staggering level. Even so, he felt a distinct sting of pain.
In his normal state, that hit likely would have left him severely wounded; had it been before he started his multiversal training, it probably would have killed him outright. His praise was genuine.
Praise aside, Goku's body didn't remain idle. He shattered the ground beneath him and threw a full-force punch directly at Hades.
"He's significantly stronger than Makarov!"
Sensing the suffocating gale generated by Goku's fist, Hades' eyes narrowed. He immediately surged his dark magic to reinforce his physical body and dodged at maximum speed.
Goku's Giant Form was only ten meters tall—nowhere near the majestic hundred-meter height of Makarov's transformation—but the explosive power he displayed was in an entirely different dimension.
He had tanked a full-power "Amaterasu Formula 100" with his bare skin, and the wind pressure from his punch was no weaker than the ultimate moves of an S-Class Wind Wizard.
Furthermore, his movements were lightning-fast, lacking any of the clumsiness usually associated with increased size. Hades realized that if he grew careless, he might actually fall here today.
"Darkness Chains!"
Seeing Goku's punching speed increasing, Hades whipped his hands forward. Two magical chains wreathed in eerie energy shot out, precisely binding Goku's wrists.
Hades gave a violent tug. Powerful magic surged through the chains, forcibly pulling Goku's arms apart and leaving his chest wide open! He had used this exact move to trap the giant Makarov, turning him into a helpless target.
"Dark Wave!"
Seizing the opening, a massive energy sphere coalesced in Hades' palms, teeming with terrifying dark power. It streaked toward Goku's exposed chest!
"Giant's Wrath!"
Goku let out a thunderous shout!
His golden Ki erupted violently around him! With a roar, he yanked his arms back in the opposite direction, physically shattering Hades' darkness chains into countless magical fragments!
Immediately following the break, he clenched his right hand into a fist, a massive tiger-shaped aura of Ki swirling around it.
"Hah!"
Goku didn't dodge. His massive fist slammed directly into the dark energy sphere. With a deafening boom, the sphere was detonated by sheer brute force!
The savage violence of the scene made even the corner of Hades' mouth twitch.
This clash was witnessed by everyone on Tenrou Island.
A ten-meter-tall golden giant clashing with that level of magical output was as unmistakable as a sun in the middle of the night.
"Interesting... even Hades is struggling. I think I'll go take a look."
Mard Geer, the Underworld King of Tartaros, raised an eyebrow. He abandoned his current opponents and streaked toward the main battlefield.
Nearby, the panting and clearly injured Ultear, Laxus, and Mystogan exchanged looks. Despite their battered states, they forced themselves to follow.
They had been fighting the Underworld King three-on-one; initially, they held a stalemate, but once Mard Geer got serious, they were quickly suppressed.
If the fight had continued for another ten minutes, they likely would have died.
But seeing the Underworld King head toward the main battlefield, they didn't hesitate. If Mard Geer and Hades joined forces, Goku would be in grave danger.
No matter how badly hurt they were, they had to pin down the Underworld King to buy Goku time to defeat Hades!
Elsewhere, Jellal sensed the commotion in the distance. He looked at the awakened inner personality of his opponent—Zero—and muttered:
"It seems it's time to finish this... Master!"
Brain (the leader of Oración Seis) had once been the head of the Bureau of Magical Development and the teacher Jellal had invited to guide him at the Tower of Heaven. However, Jellal's talent was so immense he had quickly surpassed his teacher's guidance.
"Hmph! Jellal, your talent is indeed great, but you are far from defeating me!"
Zero, his eyes blood-red and face full of arrogance, unleashed his ultimate killing move: "Genesis Zero! Open, Gates of Spiritual Wrath!"
Countless black soul tentacles flooded toward Jellal. At that same moment, Jellal's own high-tier spell was completed.
"Forbidden Magic: Abyss Break!"
The forbidden spell that once required Jose to use the Phantom MK II and the Element 4 was now cast by Jellal alone!
The chaotic energy of the four combined elements instantly purified the tentacles, drowning the arrogant Zero completely.
Once the dust settled, Jellal grabbed the unconscious Brain and headed toward Goku's location. His magic was nearly depleted, but he still had enough strength for one last stand.
Across Tenrou Island, with the help of Dumbledore's Apparition for rapid transport and support, the recovered Fairy Tail members began a massive counterattack. They rolled through the grunts of the three dark guilds like a snowball.
Everyone was converging on the final core battlefield.
However, before the majority of them could even arrive, the battle over there seemed to be reaching its conclusion.
