In an Alternate Reality IV

The Battle of Heaven and Earth

The thousands of Eldians and Marlyeans stared at the army of Colossal Titans. The Titans parted and revealed the Devil of Paradis. Their God.

"We wield an immeasurable burden upon our shoulders. This guilt is shared by all of us. We made use of hatred. We let it grow. We believed it would save us. We spat all our shortcoming on the Island of Paradis and birthed a monster.... Who has come to repay us for the countless years of hate with his own..."

"The one who can bring upon pain, suffering, futility, and regret. The one who can bring peace, justice, and joy...The God of Heaven and Earth...."

"If it's possible for us to see the future, we swear to never make the same mistakes...."

"This is nothing but a Hell. Where regret and destruction only exist. We believed that this world was our birth right. We believed that this world belonged to us...But we were horribly mistaken... It belongs to its inhabitants not only by us..."

"There's no point in us fighting back. We've come to accept it. We are nothing but bugs in his way."

An orb of lightning formed in the sky and the Jaw Titan appeared. Falco extended his wings and flew above the Founder. The Squad jumped off the plane and latched their hooks on the Jaw. Gabi and Pieck didn't have ODM gear, so the others helped them. Mikasa carried Gabi and Jean carried Pieck.

Annie was hesitant to fight at first, but there was no point in sulking any further. All their regrets were things of the past. It was time to settle the score.

Armin and Jean laid down the strips of explosive and prepared for to fight. Pieck jumped off the flying Jaw and transformed. The Cart Titan appeared and both Armin and Jean threw the explosive her way. She caught the explosives with her mouth and descended toward the Founder. She landed on the skeletal structure and went for the nape.

They all followed except for Gabi and Sasha who stayed up in the Jaw and used their rifles to take any Titans down. Their rifles weren't just any kind of rifle. They were specially designed to take down Titans.

As they flew down, Jean scouted the area for any danger.

"There doesn't seem to be any danger. Is there anything we should look out for...Armin?" Jean questioned. Armin caught on to what he was trying to do. He wasn't going to fall for that.

"I don't know. Just keep your guard up."

The Squad closed in on the nape, but before they could do anything, Titans sprouted from the bones of the Founder and surrounded them.

"Shit." Levi said then pulled out his blades.

Levi and Mikasa took off and began killing as many Titans as they could. Annie and Reiner transformed and helped them. Hanji, Armin, Jean, and Connie stayed and defended the Cart.

In the distance, the two Erens watched over the Squad who did everything in their power to kill all the Titans, but they just kept sprouting back.

"It was a smart move to save the Captain." Other Eren said.

"What do you mean?"

"In my Reality, Zeke nearly killed the Captain with a Thunder Spear. He lost an eye and several of his fingers. He was in a wheelchair after this battle." Other Eren explained.

"I felt it was necessary to save him. As strong as Mikasa is, she'll need his help. Those two combined could take anything down." Eren said.

"I see." Other Eren simply said.

"Weren't you gonna explain everything to me?" Eren questioned.

"Yeah, but once this is all over. For now, let's focus on the Rumbling."
