In Fairy Tail, starts with a Super Mega Gengar

An aura of fury rose as Makarov's roar echoed.

A psychic shield around the cable car shattered, as Makarov was engulfed in a golden wave of magic power, diving straight down toward the island below.

Seeing this, Ur quickly commanded Dragonite to follow suit.

On the island below, amidst the chaos, terrified workers fled from the magically summoned soldiers.

Blocking in front of Erza was Rob, his skin cracking all over. This was because magic power is the source for mages; without it, overexertion would deplete one's life force.

Ultimately, this would lead to depletion of life force, turning a person into stone.

In Ultear's eyes, these cult members were just weaklings lacking strength.

But for the group of powerless workers, the magic tools in the hands of the cultists were already more than enough to slaughter them, not to mention the additional magic they wielded.

More and more cultists emerged, starting to eliminate these rebellious workers.

In front of Rob, numerous cultists raised their wands, targeting him.

Crimson explosive magic arrays gathered in front of the cultists, as Rob stood before Erza and the other children, ready to expend his last bit of life.

He could die here, but these children could not.

"Freedom lies within your heart, Erza."

A vertical magic array lit up before Rob, the cracks in his skin worsening while the magic of countless cultists had already formed: "One day, you will realize your dream. I'm looking forward to it...."

Erza seemed to sense something, wanting to rush forward to grab Rob, her heart-wrenching voice rang out: "Grandpa!!!"

Bang!

Just as she touched Rob's body, a surge of magic force bounced her back.

Rob stared ahead, his eyes replaced by a sea of crimson, from the thousands of cultists wielding their wands unleashing explosive magic.

Boom!

A colossal wave of magic swept across the island.

Fireballs raining down on Rob, and under the crushing force of the powerful magic, they exploded instantly.

Rob's face showed shock, disbelief in his voice: "What is this magic?!"

In the sky, a golden light descended, accompanied by Makarov's furious shout: "Stop it now!!! Rob—!"

Upon hearing this voice, the magic array in front of Rob slowly dissipated, a smile spreading across his face: "Makarov...."

Seeing Rob dispel the magic array, Erza rushed forward to support him: "Grandpa!!!"

Tears glistened in her eyes as the other children behind her rushed to protect Rob from the cultists.

Rob lifted his aged, gray hand and gently patted Erza's head: "Everything is fine, everything is fine...."

Rob looked up at the golden light descending.

Boom——!!!

A tremendous sound shook the ground.

Makarov landed not far in front of Rob, creating a large crater upon impact. The guild master's cloak, emblazoned with the Fairy Tail insignia, flailed wildly as he turned to face Rob:

"Rob!"

Erza discreetly glanced at Makarov, noticing that the emblem on his flapping cloak was identical to the one behind her grandfather.

Rob looked at Makarov turning toward him, a smile appearing on his face, his voice carrying a sense of nostalgia: "Makarov, you've aged too...."

With those words, Makarov nearly broke into tears; looking at Rob's aged form, his voice filled with remorse: "I'm sorry, I came late."

Rob shook his head and replied: "No, just right on time."

Makarov said nothing, only clenched his fist. At that moment, Dragonite descended from the sky, Ur and Ultear jumped down, and Makarov spoke: "Ur, please protect them."

Then he turned, his attempt to remain calm now transformed into a furious snarl: "I'll go deal with those.... cultists!!!"

With a roar of anger, Makarov's magic surged, radiating endless light, his form expanding, growing larger before the astonished eyes of the laborers and countless cultists.

Makarov transformed into a gigantic figure, easily towering over the entire island, his muscular form demanding attention.

Not to mention the brilliant magic emitting from him and his furious expression, sending numerous cultists sprawling to the ground in fear.

The giant Makarov looked towards the towering structure at the center of the island, raising both hands as light magic gathered in his palms, aiming at it and launching: "Unforgivable!!!!"

Boom——!!!

An incredibly powerful beam of light magic pierced through the island and the imposing tower.

Furious and wide-eyed, Makarov roared, lifting his hands upward, the massive beam of light moving in tandem, instantly cutting through and collapsing the tower.

An explosive blast erupted, obliterating the structure.

And this....

Was merely a single blow that silenced the entire island.

Countless cultists sat on the ground in disbelief, murmuring: "Impossible, impossible...."

However, Makarov did not give them the chance to flee.

Instead, he chose the most violent way to deal with them.

The giant stood upon the island, his fists radiating infinite light, targeting the magically constructed soldiers and those cultists below.

Boom! Boom! Boom! Boom!

Each strike shook the earth.

Each blow resulted in countless casualties.

Even if these cultists had unwavering faith in their 'god', it could not compete with their fear of death.

In mere moments, they were beaten into retreat.

A tremendous wave of magic swept across the entire island, marking innumerable cultists in Makarov's vision. As he clasped his hands together, endless light blossomed from his palms.

Buzz——

An unearthly golden glow radiated, dimming even the sun in the sky.

"Fairy Law!!!"

At the end of the year X774, two events shook the magic community of Ishgar Continent.

Firstly, there was the earthquake that affected the majority of the Ishgar continent, which was triggered by the battle between Gildarts, the strongest of Fairy Tail, and Hades, the leader of the strongest dark guild.

The earthquake resulted not only in widespread devastation but also directly caused the disappearance of the Giant's Mountain Range, turning a corner of the continent into ocean.

This startling achievement led many mages to flock to the site of the Giant's Mountain Range, hoping to experience a semblance of its might.

Secondly, the leader of the dark guild controlling a third of Ishgar, one of the Baram Alliance, the Grimoire Heart guild, announced a hunt for members of the Fairy Tail guild, quickly followed by Fairy Tail declaring open war against Grimoire Heart.

Both sides were utterly determined to eliminate each other.

This was the first declaration of war in many years intending to completely destroy one another.

Countless people speculated about the grudge that led to such extreme actions, even Ur and her daughter were left confused; even asking Gaal, he could only shake his head and say nothing.

But that determined attitude was indisputable.

With Gaal's silence, no one could guess the reason, perhaps only the guild masters knew the truth.

In contrast, Makarov's destruction of an R System created by a dark magic guild appeared trivial.

In Magnolia Town.

Eastern Forest.

Inside Porlyusica's hut.

"Gaal, how's it going with Porlyusica? What's the situation?"
