Author's Note: Above is a picture I've been working on for a while, however Im still pretty terrible with shading so that work was done by my good friend Ryan_Nerd7 here on Wattpad. 

Contrary to each of the other fights that have taken place in the tournament, the entire arena is dead silent. So quiet that Husband and Wife can hear the crackling flames that sit in the basins surrounding the arena. However, silence before an Agni kai has been a long held tradition, even the screens around the arena are instructing the crowds to remain silent as the two combatants walk up to the ring. Every single firebender in the entire stadium is on their feet, straining their eyes to watch every second of the fight about to take place. The two master firebenders approach silently with the dark maroon cloaks over their shoulders billowing in the wind. Long ago, the cloaks had large heavy and layered shoulder pads that were pointed on the shoulders like those worn by the original princess Azula. Now the cloaks are little more than maroon fabric with the emblem of the firenation on the back. Midnight stands on top of her podium with a large gong waiting patiently for the two to get into positions.

"In accordance with firenation law, all firebending forms will be permitted. There are no ring outs with Agni Kai duels. The winner is decided by forfeit or rendering your opponent unconscious. No quirks, and no other forms of bending except for firebending are permitted. For our international viewers, Agni Kai duels are only used as a test of skill. In the past an Agni Kai was a duel to the death in most cases. These death duels were outlawed by Firelord Zuko the first and have become what we know them as today." Husband and Wife face each other for a moment before turning around and kneeling the eastern and western portions of the stadium.

A moment of silence hangs in the air after Midnight speaks, and the two fighters can hear her grab the wooden mallet off the side of the gong. The wooden handle tapping the side of the metal supports of the gong as she raises it in both hands. Izuku takes in a deep breath to fuel his inner flame as he feels Midnight swing the mallet and slam it into the gong. The moment they hear the gong sound, both fighters stand and shed the cloaks over their backs. Turning, Izuku can't help but smirk to himself seeing Momo in front of him. Her muscular torso glistens slightly with sweat from the heat of the day. Her chest is covered by a dark maroon sports bra that exposes some of her cleavage due to the size of her breasts. Beneath it her tight abs also draw his attention, and for a moment he almost forgets they're in an Agni Kai. She on the other hand didn't bother to take him in, instead opting to throw fire around immediately. Momo immediately crouches down into a side lunge before jumping almost 10 feet into the air with a burst of flames before swiping her extended leg around in an axe kick and slicing a massive wall of blue fire at her husband.

Izuku grins seeing her first attack and decides to meet it with his own. From his relaxed fighting stance, he slashes his hand upwards with two fingers extended splitting the wall of flames with his orange and gold fire. Immediately after she launched the blade of flames, Momo lands on the ground, springs to her feet then throws several quick punches launching curving and straight flying fireballs towards him. She had anticipated him using his hands to split her first attack allowing her other attacks to connect but that's not what happens. As The orange flames split through her blue ones, the incoming fireballs closed the distance. However his teachings through the other bending styles allow him to adapt his firebending to what he's learned. Izuku spins to the side out of the path of the flames before raising his hand and gaining control of the blue flames she had thrown at him. Momo watches as the flames she had launched orbit him, cooling slightly in temperature and turning orange before they're thrown back at her with a bit of added firepower. A smirk graces her face as she watches her attack come back towards her, lifting her hands to chest level, she throws two simultaneous jabs forwards and splits her fingers. From her nails for small beams of blue flames pierce through the air and slice through the flames sent back at her.

"Come now Zuzu, do you really think some matches and lighter flames are going to intimidate me? It's almost chilly out here." Momo taunts, feeling the warmth of the flames that dissipate and turn into thick smoke around her. As the smoke begins to clear she hears the familiar popping sounds of a combustion beam headed straight for her.

Instinctively, Momo jumps backwards spraying flames through her palms and through her feet as a line of white flames no thicker than a piano wire, pierces through the smoke and strikes the ground where she was once standing. The explosion rips apart the ring where it had struck the ground, bright white and blue flames expand outwards before cooling into red and then into smoke. Seeing this from her husband, Momo smiles widely and furrows her eyebrows. Her ancestors and past life as Azula powering her determination and competitiveness as she breaks out into a lightning generation technique. Through the mushroom cloud of smoke, Izuku flies along the ground spraying fire from his hands and feet in order to get up close and personal. Bursting through the smoke causes a line of it to trail behind him from his speed. As he closes the gap, Momo lunges airborne with her fingers pointed outwards midway through the circular motion of creating lightning. As he shifts direction and launches himself up towards her, she extends her fingers towards him firing the bolt of electricity. In the split second he saw her move to point towards him with the lightning, he managed to raise his left hand in order to catch the bolt of lightning.

Because of how close the two were when she tried to fire off the bolt of lightning, Izuku had managed to grab her hand, preventing the bolt from being fired. He feels the energy from the lightning radiate and tingle through his left hand causing him to pull his right up and then down through his stomach and then away from himself. The bolt fires out his right hand and into the sidewall of the arena destroying part of it. From the perspective of the audience it looked as if she started the lightning and he finished firing it from his other hand. The bolt arcs from his hand directly to the ground creating a large explosion launching the two firebenders even higher. Momo hadn't anticipated Izuku intercepting and redirecting her lightning bolt so quickly which gives him an opening to attack. "Sorry babe, but I got a festival to win." He says before grabbing her wrist and spinning his body before throwing her aside. Izuku sees a slight smirk on Momo's face as she rights herself in mid air and stops her momentum with her firebending. Izuku lands back on the ring, bending his knees to absorb the impact of hitting the ring. Across from him, Momo stands in the grass with a wide grin on her face.

"So, Zuzu, since you're pulling out all the stops; why don't we take this up a notch? I finally get to reveal a little party trick that Kacchan and his mother have been teaching me." She says causing Izuku's heart to drop in his stomach. Momo raises her hands up towards her chest before circling them away from her in opposite directions. Blue and white flames begin bleeding from her fingers as she pulls her arms inwards completing the circle before pulling her hands up to her forehead. The flames conceal the use of her quirk creating makeup on her skin, but with a flare of her blue flames that cascade through the air she creates something on her forehead. Izuku watches as the flames expand into the air then cool turning orange then fading away finally revealing what secret Momo has been working on. On the center of her forehead sits a vertical red eye with no accents on either side of the eye, instead two circles sit on the top and bottom of the tattoo now present on her forehead. "I believe it's time that I demonstrate why I'm the best firebender who's ever lived."

"Crap Baskets." Izuku says softly seeing the Agni eye on the center of his wife's forehead, however he isn't given much time to take it in. He almost has to resort to airbending to escape the incoming blast from her, and unlike his combustion bending her attack is damn near invisible. The beam didn't even crack in the air, and the only tell that it even existed was Momo flexing her abs and the thin line of heat radiation heading straight for him.

In The Stands.

The rest of class 1-A flinch when the explosion rips apart the ring, a massive mushroom cloud lifts up from the flames released by the attack. It isn't long before they see a thin stream of white flames answer the first attack before a second explosion takes place. "It's scary to see just what our classmates are truly capable of when they go all out." Ochako comments as she's seated beside Todoroki and Hagakure. "Can you do any of that?" She asks the ice quirk user, but all he does is shake his head before opting to put a pair of sunglasses on after another blindingly bright explosion illuminates the stadium. "I can barely make lightning on a good day, much less use psychic firebending or even combustion bending. Besides, I prefer to use my bending for creating weapons and controlling the battlefield." He responds before nudging Bakugou on the side. "Since when did you start training Yaomomo to combustion bend?" he asks, causing Bakugou to turn towards him.

"She asked my mom about it just before we went to Anchorage back in high school, but when my mother said she was going to teach Deku first she then talked to me about it." Katsuki explains before abruptly having to stand up and dissipate a stray fireball that was launched towards the stands. "The way she learned was very different from how my mom taught Deku. She did a lot of research beforehand and found some old documents about some of the first combustion benders. In the old ways, it was taught by chaining a firebender to a rock on the bottom of the ocean and forcing them to firebend without air fighting the pressure of the water and their lungs to create cavitation bubbles by the combustion bending. If you were able to combustion bend, you'd be able to break the chains and escape before getting air, if not you drowned."

"So how did Yaomomo do it?" Ochako asks through a mouthful of food.

"At our old school we had a lake that was around 50 m deep, she created a scuba tank and weighted boots then just walked into the lake with the air tank with her. I went down there as well to act as a safety diver in case anything went bad and we did this after we tested out of the mastery firebending course, it was our free period and I trained her over the course of 2 years to do this." He responds, "How else did you think I was able to afford a pink diamond that size for Camie's engagement ring?"

"I just thought you had your parents help you out with it." Shouto responds.

"Oh I did ask them, but my mother basically said that I was going to work for it if I wanted it that badly. So about 2 years of scuba diving and getting blown up by Yaomomo after she figured out combustion bending was a small price to pay."

"Did you ask her to make the diamond? They're just carbon so she should be able to create it with her quirk right?" Kirishima asks from behind Bakugou. "My dad makes a lot of money creating gemstones with his earth and lava bending."

"Yeah, she offered to pay me for training her to combustion bend but I just asked her to create the engagement ring for me in exchange for teaching her it." Katsuki explains. "She can make literally anything, but it just has to be nonliving."

"So what stops her from just making nuclear weapons and taking over the world?" Shouto asks.

"First off, world domination is far too much work, too many enemies, lots of micromanagement, it just isn't worth it." Katsuki begins, "Secondly, you're forgetting that her creations have to be made from her own body, if she was to create that much plutonium required for a nuclear bomb, she'd die of radiation poisoning long before she got even a single kilogram of the stuff."

"I never thought of it that way." Shouto says before creating a wall of ice to protect the class from a massive wall of blue flames.

Back In The Ring.

Momo skids her tennis shoes against the dirt as she slides to a stop having just evaded another explosion sent by Izuku. From the smoke of the blast, Izuku jumps out into clear view before throwing several punches launching bolts of fire directly for her. Momo lunges to the side allowing the flames to slam into the ground and burn up the grass. Now fully on the defensive, Momo blasts flames through her feet to try to gain distance between her and her husband. The blue flames incinerate the grass along the outside of the ring as she takes a wide turn to swing around behind him. Izuku however isn't going to let her gain any distance on him, adjusting his flight path so that he'll intercept her. As he changes direction, he blasts the ground with fire quickly allowing it to burn itself out turning to smoke and covering his approach. From Momo's perspective she watches him blast flames ahead of her before the flames are snuffed out and only smoke is left. The black smoke is so thick that it covers up the fire he's producing from his feet causing her to lose him.

Thinking quickly, Momo stops her forward momentum and changes direction, flying parallel with the wall of smoke her husband has created. Try as she might she can't find Izuku anywhere in the smoke and that fact starts to eb anxiety through her body. She stops back in the middle of the ring, frantically scanning through the smoke the anxiety begins to build and build until she can't take it anymore. Frantically she starts throwing fireballs blindly into the smoke trying to burn it away and to find Deku, even blasting both lightning and combustion beams into the smoke. The shockwaves from the lightning and the combustion push away large clouds of smoke but she suddenly notices that the smoke is behaving unnaturally. It isn't rising or even dissipating, and as she studies it for a moment she realizes that the clouds are also getting bigger and starting to wrap around her. Her instincts scream at her to get out of there as the smoke begins to cause her to cough, but she knows if she moves Izuku will have the chance to ambush her. Internally she's cursing at herself for not reading a bit more about smoke bending.

She begins to backpedal away from the growing smoke, scanning the black clouds in front of her she makes the mistake of turning her head to look towards the edge of the clouds that are wrapping around her. The moment she turns her head away from the smoke clouds ahead of her, Izuku lunges from the smoke. Momo barely has time to even look towards him as he grabs her by the face and sweeps her legs out from under her. She half expected to land hard on the concrete arena but Izuku stopped her from slamming against it. With his hand clasp over her mouth and his other sparking with electricity he smirks at her before saying one word. "Submit." He demands, for a moment, Momo thinks about resisting, freeing herself and tackling him but she doesn't. She nods allowing him to move his hand away from her mouth before speaking. "I submit." She concedes, and as the words leave her mouth the crowd goes wild. With the crowd roaring around them, Izuku helps his wife off the ground before she smiles having finally been defeated by her husband.

"So Zuzu, now that you've one, what do you plan on doing with our little bet?" Momo asks as she walks her fingers up his chest then rests her hands behind his neck.

"You'll just have to wait and see. Lala." Izuku says as he wraps his arms around her waist and presses his forehead against hers with a wide grin on his face.
