Wanda and Vision were living happily, untouched by the events involving Thanos.
After the Skrull invasion, they cherished their time together even more.
As they enjoyed each other's company, Wanda's eyes suddenly flashed, and she abruptly stood up.
"Wanda, what's wrong?"
Vision, noticing Wanda's sudden change, frowned.
"It's nothing, I need to step out!"
Wanda shook her head and walked out, not waiting for Vision's response.
Vision, seeing Wanda's behavior, knew something was wrong.
His eyes glowed, revealing strange energy surrounding Wanda.
Boom!
Cosmic energy spread from Vision's forehead.
With this powerful force, the energy entangling Wanda dissipated.
The black light in Wanda's eyes vanished.
"What happened to me?"
Wanda felt something was wrong but didn't know what had occurred.
"You seemed to be under someone's control!"
Vision said, "I had to use my energy to dispel it!"
His forehead's energy began to weaken.
But thanks to Wang Yan's efforts, it was still enough for him to live.
"Yes, I was controlled!"
Wanda sensed it, too.
Given her power, she shouldn't be easily controlled. Defeated, maybe, but not controlled.
At that moment, a black energy infiltrated the area.
This dark energy was siphoning away Wanda's chaos magic.
Black marks appeared on Wanda's face.
Vision frowned, transforming back into his proper form, his forehead glowing, and fired a beam.
In an instant, the beam pierced the wall.
Boom! The wall collapsed, revealing Agatha, their neighbor.
They had seen her before but never interacted much, thinking she was just a friendly neighbor.
But now, she exuded a dark power, her aura terrifyingly dark.
She was using magic.
"She knows magic, and it's dark magic!"
Wanda, having learned about magic from Wang Yan, recognized it immediately.
This dark, evil power was dark magic.
But why was it here, near her?
"Agatha, what are you doing?"
Wanda frowned. Unlike Vision, she knew more about their neighbors.
"Wanda, your power is immense. Why not give it to me?"
Agatha looked at Wanda, eyes filled with eager desire.
"She's being controlled by her own power!"
Wanda realized.
Powerful magic could backfire and control the user.
Magic was a double-edged sword.
Especially dark magic, which was terrifyingly corruptive and uncontrollable.
Agatha's magic had backfired, causing her power to consume her.
"What do we do?"
Vision frowned, knowing Agatha wouldn't be easy to deal with.
"Attack quickly, subdue her!"
Wanda gathered her chaos magic.
"If you won't give me your power, I'll take it myself!"
Agatha shouted, her dark magic surging.
Empowered by Mephisto, Agatha's strength had increased dramatically.
The house collapsed instantly.
Hearing the commotion, the residents of Westview came out and saw Wanda, enveloped in red energy, and Agatha, surrounded by dark power.
Vision stood nearby, wearing his cape.
Boom!
Red chaos magic, controlled by Wanda, shot towards Agatha.
Agatha's powerful dark magic spread out. As a descendant of witches, her control over dark magic surpassed Wanda's. Wanda's chaos magic couldn't resist the approaching dark magic.
Boom!
The dark power struck Wanda, sending her flying.
She crashed into the ground, creating a vast crater.
A beam of light shot from Vision's forehead towards Agatha.
Agatha conjured a dark aura to shield herself, but it couldn't withstand Vision's energy.
Agatha fell, crashing into her house and landing in the basement.
Mephisto, still examining the Darkhold, turned to see her.
"Who are you!"
Agatha, already crazed, saw this stranger holding the revered Darkhold.
Agatha's dark magic surged towards Mephisto.
But what was powerful dark magic to Agatha did not affect Mephisto. It vanished instantly.
"Such simple power is useless against me!"
Mephisto glanced at the dissipating dark magic, then at Agatha.
"You've been here a long time, haven't you?"
"Since Vision and Wanda arrived in Westview, you've been here, siphoning Wanda's power, even after Wanda was replaced!"
Mephisto seemed to see Agatha's past, his power revealing everything.
"Interesting, chaos magic? I didn't expect such power on Earth!"
Seeing chaos and magic in Agatha's mind surprised even Mephisto.
Chaos magic was one of the most extraordinary powers.
A primal force of the world.
Greed shone in Mephisto's eyes.
He had come for the Darkhold to enhance his power.
He never imagined finding such power on Earth.
"I must have this power!"
Agatha muttered, seemingly bewitched by Mephisto.
"Go, show me the strength of chaos magic!"
Mephisto waved his hand, and Agatha's dark magic intensified.
Feeling the surge in power, Agatha was thrilled.
She flew out, her power now more controlled.
Far from the house, Wanda and Vision stood side by side.
They should have called for backup, but it wouldn't be quick with the Avengers in hiding or busy, which would take time.
Besides, they had the upper hand.
They believed they could subdue Agatha.
But they didn't understand why this was happening.
They had been peaceful for so long, even after Thanos and the Skrull invasion. Why now?
But this wasn't the time to ponder.
A terrifying dark magic erupted from the house, enveloping Westview.
Wanda and Vision saw the encroaching darkness, their faces solemn.
This power was far more potent than before.
"Such strong power. Why has Agatha's power increased so much?"
Vision could sense the powerful energy.
If Agatha's power was a firefly before, it was now a flashlight, vastly stronger.
In moments, the dark magic surrounded Westview.
The residents felt the power, becoming erratic and crazed.
Meanwhile, S.W.O.R.D., monitoring Earth's changes and space activity, detected the shift in Westview.
"Director, special energy readings from Westview. Should we investigate?"
A S.W.O.R.D. agent reported.
"Yes, send a team immediately. If there's danger, call the Avengers!"
Nick Fury nodded.
After several upgrades, S.W.O.R.D.'s space base was now potent.
It was incomparable to the past.
They could monitor a million-light-year radius and Earth's data.
Any power emitted was detected by S.W.O.R.D. and dispatched to Earth teams, making them far more efficient than S.H.I.E.L.D.
A team was sent to detect the change in Westview.
Nick Fury, looking at the energy readings from Westview, was unphased. He had seen more extraordinary powers, so this wasn't much.
"Continue monitoring space. Earth's situation is under control. Are the Earth-launched weapons and equipment ready? We need to strengthen our forces!"
Nick Fury issued orders calmly.
Meanwhile, outside Westview, a portal appeared, and Wang Yan stepped out.
Seeing Westview shrouded in dark energy, he was grim.
He thought the world had changed completely.
He didn't expect that only time had been delayed, and Westview was still engulfed by magic!
