LoK and AoT crossover! After the Book 4 finale, Asami Sato and friends are working to clean/rebuild until they come across a portal of sorts that throw them into a world of Titans. Levi/Asami half-siblings. Only wrote a prologue because I want to see this idea done! Details at the end.

Disclaimer: Recognizable characters belong to their own franchise.

A few months after the downfall of Kuivira, Republic City and the Earth Kingdom had begun to settle down and slowly gather themselves to thrive once more. Avatar Korra, along with others, have been traveling to devastated cities and towns from the tyranny that had been built up for many years. It was a painfully slow process, yet they could see progress on the horizon.

Asami Sato spent most of her time helping to rebuild Republic City from the mess caused by the giant metal machine that rampaged through there months earlier. The united city already had definitely gained much in recent years between a forest grown in the middle of the city overnight, spirits wandering about and now an accessible portal to the spirit world itself.

The Avatar, Master Tenzin and the President of Republic City himself have cautioned civilians from wandering the realm unless they had a guide, such as an Airbender. A handful of people of course had wandered inside the portal and caused minor search parties. They were unharmed for the most part, mainly utterly lost. Since then, precautions and a barrier had been put in place to prevent further incidents from wanderers or troublemakers.

Asami glanced at the tall beam of light with a small smile, recalling when she first went into the spirit world with the Avatar herself just after the Kuivira incident. The pair had gone through again with other friends. The dark-haired young woman turned away and sighed wistfully. That seemed like a long time ago. Now, they all had responsibilities to the city and the world to take care of once more. Hers at the moment was to clean up the remaining pieces of the giant mecha suit scattered about.

"At least we've been able to reuse most of this for strengthening construction." She mused to herself in a positive note.

Being an inspiring inventor herself, of course Asami used some of it for gadgets and inventions of her own creations. She brushed her hand against the shock glove hanging to the side of her belt. A thought crossed her mind to possibly upgrade her favored weapon she 'inherited' from chi blockers years ago. It had come quite in handy. Especially when you fight alongside the Avatar and friends as a non bender.

The young woman focused her attention back on the large armored piece in front of her on the outskirts of the city. With a mini saw in hand, she pulled down her goggles and carefully cut it into manageable pieces.

"Need some help?" A voice called. Asami pushed up her goggles and gave a smile and short wave to her approaching friend, Jinora, who was closely followed behind others. The teenage Airbender master gave a bright smile as she came closer.

"We just came back from a little expedition in the spirit world." The younger girl explained.

"It was awesome!" One of them exclaimed.

Asami gave a soft laugh at the excitement. "I wouldn't mind a few helping hands." she admitted. They all gathered around to help lift pieces onto a sturdy wagon to be taken back to her workshop.

As they were finishing up, Asami couldn't help a strange feeling that overcame her. It was as if something was tugging at her. Feeling utterly confused, she looked around. It didn't seem to affect any of her other companions.

"I'm going to check something out." She said aloud to the others while not even looking their way.

Asami began to walk up the small hill in the direction where this feeling was pulling her. She paused at a spot behind a tree that had a heavy air to it.

"What is that?" Jinora asked, the others joining around her. The young airbending master was sensitive to spirits and such and could now sense something unknown in the area.

Asami shook her head with no answer to give. As she looked closer, a slight glimmer could be seen behind the tree. Curious, the young woman reached out towards it.

Suddenly, a barrage of images flickered through her mind including a little dark-haired boy being held by a young woman who greatly resembled herself. Her mother.

Asami gasped as she felt her whole being pulled from her center followed by the rest of her body. She could barely hear similar reactions from around her before everything went black.

In the outskirts of Republic City, a full wagon sat with no one around in sight.

I am only going to write this far because I feel like I don't know enough about Attack on Titan to give it the justice it well deserves. Although, I would love to see this story come to life! I put things together to give a way that their world could meet. Now I did not do the Titans side at all because I would like for whoever takes this idea on to decide exactly when they end up in the Titan storyline as it will now become YOUR story. I just gave a couple of characters that you can play with from Legend of Korra with more for YOU to choose from of so desired. I will have a list of vague requests in a moment I would love to see used as well if possible.

Now I am aware that Levi's mother died while he was young, but I couldn't shake the idea that, 'what if Asami Sato from Legend of Korra was also related to him?' Of course, for that to happen, what if his mother didn't die, but instead disappeared for so long that she was thought dead? She ended up sucked into a portal that led to the Bender's world and eventually met Asami's father, fell in love, and had Asami. I picture the two half siblings at least 10 years or so apart. The details for that tale is up to the new writer to decide and if other random Titan characters ended up with her fate. If YOU go this direction, please do NOT have the legit Titans show up in the Bender world. And how the relation is figured out can be YOUR doing as well. Examples: Asami looks just like mom, she recognizes the name Ackerman, etc.

*Now here are my requests. YOU are welcome to turn down or alter however YOU want.:

-If YOU choose more LoK characters that transition over, keep it a reasonable amount to juggle. I'd suggest 10 at most, including the two I gave.

-NO AVATAR. I feel like that would cause an over advantage.

-At least one bender of each element. These can include a few OC's if desired. A good female firebender would be nice to see. :)

-Keep a majority, if not all, of them teenage/young adult age. Example: Jinora is about 14-15 here and Asami I would put about the age of 22-23. May help to have others in their age range.

-At least ONE character succumbs to a Titan. They are thrown into a new world. There will be casualties. Can be a random OC if desired. If a bender dies, the Titan does not gain bender abilities.

-Please do not kill Jinora. I don't care who else YOU decide to bring in, but please keep her alive. I feel like she would be a huge benefit in uncovering the Titans' secret and helping out with her ability to astral project and major knowledge of spirits among other things.
