AMS
Frans pushed against the wind with the flames from their feet to come to a stop and land on top of the mech without shaking it too much. For her sake. They looked through the window and there she was. Her hair was even more of a mess due to her intense perspiration, her skin was paler than last time, and she had grey bags under her dull green eyes. She couldn't speak, nor could she even look straight ahead at them without swaying. She shakily reached out to them, sobbing as she felt her life slip away more and more.
Determined to save this woman, they plunged the sword into the bottom of the top and sliced a hole big enough for them to jump into. They metalbent the hatch open and jumped right in. Before the spirits could even think about jumping right back into Kuvira, Frans pulled her into their arms and jumped out of the suit. Using fire from their feet, they flew away from the spirits and into Asami's office.
"Whoa! F-Frisk?" Shouted Varrick who was busy working on a second sword.
"Yes, but no. Kuvira she… was forced by the spirits. Her health is low. I can see it. Please help her!"
Asami quickly dropped her blueprints and ran right over to Kuvira. "She's suffering from a spiritual attack. Since you fused with Sans you can bend all four elements, right?" Frans nodded, unsure of where Asami was going with this. "You need to go into the spirit world through the portal with her and put her in spirit water. Not the lake of prayers, but the one in front of the Tree Of Time. Bend the water to heal her spirit."
"I've never healed using water before…" Asami grabbed their shoulders and looked them square in the eyes. Her emeralds danced with emotion.
"I know you can do it. Just focus on her energy when you do it. Focus on saving her. Now go! You're running out of time."
They grabbed Kuvira again and set her over their shoulder. They made a mad dash toward the window they burst through and jumped, forming an air vortex under them.
"S… av…." Kuvira lifelessly choked out. Frans shushed her gently.
"Save your strength. It's going to be okay."
A few tears fell from her even more faded green eyes, but Frans kept her from closing them as they kept talking to her. They told her a story about Frisk and Sans and how they found this world. It was so interesting that Kuvira couldn't help but listen. Whenever they saw her eyes droop, they raised their voice, alarming her eyes back open. Almost to the spirit portal. Just a bit farther!
The airbenders below looked up and saw Frans go through. They abruptly stopped bending but stayed on their feet, ready to defend if necessary. Zaheer was still sending spirits through the portal. Frans gently set Kuvira down in the water. Her health continued to fall. Focus on her energy, huh? Maybe like this?
From inside Kuvira, her soul glowed. She has a dark green soul. But I can tell it's supposed to be a lighter green.
From all around them, Frans saw the spirits coming for them. Crap! This is bad. They immediately smiled when Zaheer, Jinora, Ikki, Meelo, and Tenzin all rushed in and stood around Frans, defending them from oncoming spirits. Thanks to them, Frans was able to concentrate on bending the water side by side. At first, all it did was sway Kuvira around a bit.
"Focus on her energy. You can do this."
Those words did something to Frans as a blue flame ignited from their eye, and their heart swelled with overflowing determination. The water now glowed a bright blue as it began to slowly heal Kuvira's spirit. Little by little, her soul turned back to its natural hue. The angry spirits were closing in as well, but Frans didn't stop the healing process as they were so close to saving her.
Zaheer grunted as he sent air blast after air blast. Sweat poured down Tenzin's head and into his beard. Jinora felt uncomfortable with how much she was pushing herself, but she kept going, knowing Korra couldn't save them now. Meelo wasn't breaking a sweat at all but his brows were knit together, worried for the world, his friends, and his family. Ikki looked plain angry at the spirits for taking away two lives in one day. She vowed to herself to not let them take another.
At long last, Kuvira was healed. As soon as they saw her soul turn to its natural color and she fell into a deep slumber, Frans immediately threw a horizontal fire blast, throwing all the spirits back to give them space. Grabbing the water, they purified the angry spirits into calm spirits.
"Go in peace," softly said Frans.
They picked Kuvira up bridal style and they all came out of the portal to find everyone else standing there, clapping. Medics came immediately to take Kuvira to the still-standing hospital while everyone took in Republic City's sight. A whole row of buildings had been destroyed. Frans sighed before turning back to face the portal.
"This is why the Avatar needs to be a bridge between the spirits and humans. Spirits are just too powerful in our world and too dangerous. Maybe if Frans works with the spirits since they're half monster, then maybe one day, an understanding will be reached," said Ikki in a sad tone.
"Then how will I see Bumju?" Sadly asked Bumi as he stroked his furry spirit friend fondly.
"Meditate into the spirit world like the ancients once did," answered Tenzin. He placed a reassuring hand on his older brother's back.
Frans gathered all the spirits in Republic City and guided them into the portal before they used energybending to close it. They sped across the globe using an air vortex, guiding any and all spirits they see into the other portals before closing those. They were sad, knowing separating spirits and humans won't help them grow, but since spirits almost caused the Avatar cycle to stop, spirits just couldn't be trusted yet. The world needed a middle man to mediate between the spirits and humans, even between them and the Avatar. As soon as all the portals had been closed, the vines in Republic City retracted into the ocean.
I will be the bridge between the spirits and the Avatar.
A month later Asami held a funeral for Sans and Korra. The world leaders, airbenders, water tribes, earth kingdom citizens, and fire nation all wore black, and bowed their heads in respect for the fallen as Asami spoke with an emotional tone. She didn't care. For now was not the time to be strong. Now was a time to grieve, to fall on your friends and family for emotional support, to just feel.
"Even though Sans did some bad things at first, he gave his life to protect Korra in the beginning of the battle. Now he lives on in Frans, who has promised to dedicate their long life here, protecting us in the Avatar's absence. They will take it upon themselves to counsel the spirits in hopes they may return one day. As for Korra…" she blinked and a couple tears fell. She slowly wiped them away just for more to fall. "I loved Korra more than anything. She was a brave and beautiful Avatar, and the best girlfriend I could have asked for. She laid down her life often for the sake of others, but this time, she couldn't come out of it."
She shuddered a sigh out, but kept going. "I know a lot of you are confused and angry with Zaheer for snapping her neck, but please understand that he is a hero for doing so. Had he not killed her, there would be no more Avatar cycle. I-I can't keep going. I have to step down now."
No one clapped, and no one said a word or even looked up as Asami got down from the pedestal and stood next to the only other people who was like family to her: Mako and Bolin. Bolin squeezed her shoulder while Asami just leaned against him for support.
Frans sighed and walked up to the pedestal. "It's just as Asami said. I'm here to stay, to protect, and Zaheer is definitely a hero. And he-" they paused as tears flowed. "He's such a good man, honestly. Since fusing with Sans, I retained his memories. So I know how he at first manipulated Sans into swapping bodies, but how he fell in love and changed his ways. But that's for another time. For now, the spirits are in the spirit world, and the world is at peace for the time being. Let us all take a moment to quietly thank Korra and everyone else for a job well done."
As Frans stepped down, they went over to Asami to give the genius a heartfelt hug. Once they broke away, they walked over to Tenzin and his family. They all shared a group hug. They then walked over to Zaheer, reached up, and pecked his cheek. Zaheer looked at Frans in surprise before he smiled at them and pecked their forehead, right on the arrow.
After the funeral ended and Korra was buried, Tenzin, Zaheer, Jinora, Asami, Mako, Bolin, and Raiko approached them. "So are you going to unfuse from Sans or-?" Asked Raiko.
"A fusion between monsters and humans can only be undone by death. Not that I'm complaining since Sans' spirit can live on inside me," answered Frans. They lightly touched the heart shaped necklace as they replayed Sans' death in their mind.
Jinora leaned in close to Zaheer. "How do you feel about that?"
He leaned down. "As long as they love me, I will love them."
He walked up to Frans and immediately blushed when their eyes met. One eye on Frans was Frisk's eye color. The other was a light blue, indicating that was from Sans' influence. "Frans I… I still love you, if that's okay with you…"
A crooked smile crossed over on their face. "Just know that I am neither Frisk or Sans. I am a new being altogether. But I do know you loved Frisk with all your heart, and that you did respect Sans to your fullest capacity. I can't help but love you back."
They opened their arms and jumped into Zaheer's embrace before their lips met passionately.
A year passed by with little to no worries other than finding the new Avatar, and being new parents.
"Zaheer! The White Lotus called, saying there was a claim in Zaofu. Can you please watch Fuyu?" Shouted Frans.
Zaheer came in the room and picked up their giggling one month old baby. One eye was a deep green where the other was a light blue. The baby giggled loudly, making the small furniture around them levitate. "I sure hope I survive this child, haha."
"You'll be great. See you later," Frans said rolling their eyes. They pecked Zaheer on the lips before dashing out the door.
"There they go. Now it's just the two of us. No levitating furniture or it's bedtime for you, young lady," Zaheer said, wagging his finger.
Fuyu stopped giggling and went straight to screaming, causing bones to be summoned and fly towards Zaheer who just used airbending to make them fly around him and break the furniture and crack the walls. I need to be careful with what I wish for.
After a few false alarms, Frans and the White Lotus eventually found the new Avatar, but they all agreed to wait until their sixteenth birthday before revealing it to them.
"The Avatar will be allowed to travel, even if anyone tries to attack them when they are a baby. The Avatar needs to know about the different cultures after all," demanded Frans. "I'll be going with him of course."
"What about your child and husband? You'd leave them behind?"
"No. They'd come with me. Times are changing. Frisk came here in hopes to help save this world, and I have the power to make her dream a reality."
