Horror was evident on Michael and Natasha's face as they watched the scene unfolding infront of them through Wanda's power as she projected the images of what was happening in the alternate reality, she was still holding her two newly born twins, thankfully they had settled in her embrace as they latched on to either breast, unknowingly shielded from the horror that the adults were watching.

"NOW!"

Wanda had shouted, queuing Dr Strange and Woo to open the portals, allowing all the avengers, their allies to pounce on Thanos and Ultron.

Ultron surprised by the sudden attack leapt for Wanda but was forced back and slammed against a wall by Pietro who had ran at him, Pietro smirked as he looked down at the android.

Wanda watched Pietro intently as she remembered the last time that they went up against Ultron, resulting in her Worlds Pietros death. Her scarlet screamed out as the memory flashed before her, causing her to gravitate in the air as she flew to Pietros side, she knelt down next to the Android, time seeming to hold still as she held her hand out as she spoke, her words full of hatred

"Did you know that I have already killed you? Like you killed me"

Ultron chuckled, causing Wanda to frown, a frown unpleasant, a sense of evil cascading her scarlet eyes as she slowly beckoned her magic to pull at the wires inside the androids chest.

Everyone stopped their attack on Thanos as they watched Wanda, noting the Scarlet aura that surrounded them, it wasnt frightening, it was more of a shield, ensuring everyone's safety.

What did scare everyone the most was just how painfully slow Wanda had Ultrons chest, whatever he had for a heart was moving millimeters, small but excruciatingly painful, his screams were causing everyone to grimace, even Pietro who decided to pull this alter World version of his sister from her sinister thoughts by laying a steady and firm hand on her shoulder.

Wanda's eyes blinked and she quickly pulled out a large metal 'heart', watching as Ultrons red eyes dimmed to darkness.

She stood and turned her gaze to Thanos who was eyeing her intently, he smirked as he spoke

"You will be perfect for my bride"

Vision frowned and flew to Wanda's side, placing a protective hand over her waist as he spoke

"She is not a novelty item that you can merely pick up"

Wanda smiled at Vision and put a loving hand over his, moving his hand from her waist as she stepped forward.

Her accent was thick as she spoke, ensuring the hatred that she felt for the Titan was spitting out with every word.

"There is a version out there in this vast multiverse where Pietro is gone, Vision is gone, Natasha is gone, Tony is gone and I killed myself.. all because.."

She began to rise as she continued, malice slicing through the air as she watched him, her scarlet energy shot out, engulfing Thanos

"All because you wanted to play God!"

Her powers began chocking around Thanos thick neck, he started fighting back causing Wanda to scream as her power flared wildly towards him.

"You are the reason for all the pain that I have and would have ever experienced! You! You are the parasite that needs to be eradicated from the World"

Her tendrils fused around Thanos, everyone stood watching in both awe and terror as she held the titan in a vice with her powers.

"Wanda"

Vision shouted out to her, ensuring that her mind stayed grounded to where they are, the stone ontop his head shining as he watched her dive deeper into chaos.

Pietro noticed Visions cries to his sister and felt the tugging of the space stone inside his subconscious and decided to join in, he too calling out her name, grounding her to their reality, keeping her mind, her own.

Everyone else eventually joined in, ensuring that they kept repeating her name, pleading that she stay with them.

Her powers began to falter as her mind drifted away from the chaos, she looked to Vision and gave a simple nod to show that she was there before darting her eyes to Thor as she shouted.

"I cant hold him much longer! You need to do it now!"

And with that Thor shot up above Thanos holding his Mjölnir, ready to strike down as the electric tendrils of lightning glowed around him.

Wanda released Thanos as Thor met his head with the hammer and ensured her scarlet aura was hugging her allies, shielding them from the blast that Thor had created.

With one last thump Thanos' head was now severed from his body.

Everyone cheered and Dr Strange noted that this was the best outcome, nobody on their side had suffered any losses.

Wanda smiled as she watched her family cheer, Vision coming up along side her, she fell into his chest as she closed her eyes.

She was well and truly tired after expelling so much energy.

Vision held her close, allowing her to rest.

Dr Strange and all those from other worlds, said goodbye to their counterparts before leaving into portals that would send them to their time in reality.

Vision, Wanda and Pietro entered the portal hand-in-hand as Dr Strange watched.

Wanda and Michael who had been watching the events unfold through the power of the reality stone felt a sudden twinge within their being.

A feeling that reminded them of someone saying"Thank you"

Wanda looked to Michael, tears welling in her eyes as she asked if he had heard it?

He nodded and they both came to the understanding that it was the voices of the souls of Wanda and Vision, the souls of their past lives, ones that had endured so much heartache in such a short amount of him, a version of Wanda that had lost everything that she had ever loved and had eventually decided to give up on her life.

And a version of Vision who had been taken from his lover, plucked out of existence as Thanos so cruelly plucked the mind stone from his head, they ran out of time.

"Do you think they are at peace now?" Wanda looked to Michael, tears spilling from her eyes.

He placed a loving hand on her cheek as he spoke

"Yes they are, they are us, they are together again" He glanced down to his sons as he smiled, placing a kiss ontop of both of their heads as he finished his statement.

"They are simply WandaVision now" He chuckled at the statement and Wanda couldnt help but laugh and cry at the same time as she thought of what that statement could mean, but yes she thought WandaVision is definitely the best way to describe the souls that had taken up residence within their bodies.

It was thanks to the souls of WandaVision that they were able to defeat Thanos, and create a family.

In this reality, in these bodies, Wanda and Vision were finally reunited and they had all the time in the World to spend together with their sons.
