Onyx instantly sprints for me while I hold the greatsword with my right hand and reel it back behind me. Once she's within range, I turn my torso to the left and pull my arm and the sword as hard as I can, the massive blade arcs around me horizontally where it impacts her slab of metal.

The resounding gong of heavy metal slamming against one another rings out in the Arena. She grunts as do I as we recoil from the strong blows.

Gripping the sword with both hands for better control, I start swinging quickly, forcing her to parry and defend against my strikes.

She struggles to keep up getting the crowd to sound worried, but she then surprises me by twirling her body and parrying my strike while swinging her left hand out and haymakers me in the head.

I yelp in shock and tumble across the ground for a few seconds. I recover and shake my head as I realise I've dropped the sword from the surprise. I roll my neck and crack my knuckles as I quickly sprint to the wall and grab a large battleaxe. It's much heavier than the sword, and feels like five-hundred pounds of pure steel.

I smirk as I heft it up with both hands and charge at Onyx. She huffs and kicks at the ground a couple of times before charging at me as well.

We both swing but this time my strike forces her back with the greater force and weight. She reels back and I follow up with a high jump and a dropkick to her head. With a grin, I return her face strike with my own and send her tumbling across the ground.

She recovers with a slight wobble and bloody nose. She growls and picks up her sword before walking menacingly towards me, dragging her sword along the sand covered ground.

I spin the axe a few times in my grip as I walk towards her as well. The crowd cheers her on and once we reach each other, we begin slugging again with our weapons. This goes on for a couple of minutes before she roars out and slams her weapon into the ground.

The ground shakes from the sheer force making me almost lose my footing. With a smirk I move back in to continue our trades, neither of us landing a blow with our weapons. Although I'm not aiming to injure her.

"Not bad, not bad at all. But you're going to haf'ta hit a lot harder than that!" I say as I use my wings to fling myself at her, using the axe as a shield and slam into her sword as she uses the flat to guard herself with. I bounce off her and she falls flat on her ass.

Landing on my feet I twirl my axe and start circling her as she stands back up.

"I think we both know how this is going to end. But to be honest? It's been a long time since I've had a fight just for fun and not to defend my home or people, or just to punish someone for attacking us. I hope you're enjoying this just as much as I am!" I tell her and wait for her reply and to get ready for round three.

She snorts but a smirk is on her face as well. "I will admit, you're the first to offer up a decent challenge. Most of my opponents don't last long against me, and so far you've lasted the longest! I am very much enjoying this. Now enough talk, let us continue!" she replies and charges with her sword.

I swing with an uppercut which she slaps my axe with the flat of her blade away. I spin around and use the momentum to strike at her left hip, she steps back just avoiding the axe and quickly steps forward and headbutts me on my forehead.

I grunt from the blow and as I lean back, I drop my axe and place my hands on the ground and bring my knee up, slamming it into her jaw.

She yelps in pain as her head goes back and forces her to stumble backwards. The crowd cheers and it's no longer just for her, but for the both of us as we put on a grand show of combat.

I cart wheel back and notice I'm next to the sword I first used and pick it up. I also notice a large dent where we first hit each other's swords.

And so for a good ten minutes we trade blows and she finally manages to get a solid hit on my left arm, fracturing it with the force. I groan in pain as my regen kicks in and repairs the damage.

I think I've given the crowd and Onyx a good enough show and start to get serious. I increase my speed and start to rapidly hit her sword near the handguard to make her lose her grip and after a good thirty or so hits, she finally gives in and releases her sword due to the pain of absorbing so many hits.

I quickly shoulder tackle her onto her back and sit on her stomach, her breasts resting on my lap while I hold the sword from the grip and blade and gently press it to her throat.

"And I think that's my win," I comment cheekily.

She tries to push the sword but I carefully keep it at her neck. After a minute of struggling, she goes limp and sighs.

"I concede..." she says, making the crowd go silent.

After a good few seconds of nothing, the crowd starts mumbling amongst themselves.

"C-C-Chieftain Onyx has conceded! T-T-The winner is the O-Overlord of T-Tartarus!" Mister announcer says, getting my attention and making the crowd clap but not cheer.

I look back down and see Onyx blushing and looking at my lap where I follow and chuckle at seeing how well her chest fits on it.

I stand up and remove the sword from her throat and offer a hand to her.

"So, by your own words, will Minos ally with Tartarus and Equestria? Oh and also refuse to help the Gryphons in attacking us?" I ask her.

She grumbles and grabs my hand and I help her back onto her hooves.

"I am a heifer of my word, I will not help the Gryphons attack you or Equestria and will also sign a nonaggression pact with Tartarus," she replies and dusts herself off before picking up her sword which is slightly damaged.

I grin and toss my sword to the ground. "Great, also if you would like, I could offer you more power and possibly eternal life if you want. I can make you a Balrog like my two warriors, and with how strong you are now, you may even end up an Archdemon or possibly a Demonlord. So, what do you say?" I ask her.

She looks shocked I would offer such a thing. "Why would you offer me that?" she asks in confusion, but not outright refusal.

"I look out for my allies and friends, and if I can help you become stronger so we could help each other when needed, why not? And it'll help you protect your people from powerful enemies. There will be conditions of course, such as you wouldn't be able to attack me or my people with intent to kill without feeling pain. But, it's your decision. We have plenty of time to think it over," I reply.

She looks down in thought, a frown on her face as she thinks it over. I grin as I see her glance at my Balrogs and then to her left hand.

After a minute or two she looks back at me. "Alright, I'll accept your offer. In return for this power, I will aid you should you need it. Now what do I have to do?" she tells me and asks.

I smirk as I walk over to her and without warning, grab her right horn, tilt her head getting a yelp from her, and bite into her neck.

"Ahhh! What are youuuuuu... Argh!" she demands in surprise, but then grunts as her body starts changing. The crowd gasps and goes silent.

She grows a couple of inches, her muscles become more dense and defined, her armour groans before the straps holding them snaps, leaving her in just a tight fitting pelt bra and loin cloth. her fur turns black, long white hair grows from her head down to her mid spine, her eyes turn ice blue, her horns a dark purple.

She grabs onto my body in discomfort and I grunt as it feels like she's trying to snap me in two. After a good minute, the changes stop and I release her. Although she still has me in a bearhug.

I raise an eyebrow at her as she breathes heavily, her eyes are unfocused as she pants and shivers.

"So... S-So much power... I feel... great!" she says and without warning, kisses me hungrily.

I go wide eyed as she vigorously makes out with me in front of everyone. I quickly get my wits back and frown. She want's to play like that huh?

I twist my right leg behind both of hers and pull, making her trip and release her grip on me. I grab her around her chest and hold her from just falling over, I then kiss her myself and force my long tongue into her mouth which coils around hers, making her moan and due to all the sensory stimulation, she passes out and I gently put her down.

My oral muscle slowly slithers out of her now limp lips and jaw with a loud slurp. I chuckle at the dazed expression on her face and wonder why she kissed me without warning. I'll just have to ask her once she wakes up.

I look around the now silent arena where the crowd just stares and doesn't know what to do.

Ironhoof and Thunderhorn both run up to me, both with shocked expressions.

"So..." Iron says awkwardly. "What do we do now, my Lord?" he asks.

"I guess we wait for Onyx to wake up and then we get around to making that treaty. Why don't you go and visit your family while I wait. This might take a while," I inform them and sit down next to the out cold chieftain.

"Are you sure?" Thunder asks me.

"Yes, now go. If you can convince your family to come with us, warn them that they'll either live in our town as minotaurs, or come to Tartarus as Balrogs," I tell them, getting nods from both of them.

I spot some of Onyx's warriors making their way over to us and I sigh as I glance at Onyx. She now has a dopey grin on her face and giggles. Really doesn't fit her new appearance.

My brother and I leave the arena and make our way through the city with a couple of warriors following us. Minotaurs who didn't come to the arena stop and stare at us or take cover. I smirk at a young calf who has a wooden sword in his hand gawk at us as he drops his sword in surprise.

It doesn't take long to reach the two floor home we grew up in and sigh as I stare at the door.

"Are you alright, Iron?" my brother asks me.

I shake my head and huff. "I will be once we get mother and sister out of here," I reply and knock on the door.

The door slowly opens and a young fifteen year old girl with white fur and brown hair with cream coloured horns and blue eyes looks up at me. I smile at the sight of my little sister, but then get a shocked expression as she yelps and slams the door shut.

Thunderhorn chuckles and I pout as I knock on the door again. "Heartsong!? It's us, your brothers!" I tell her, getting a gasp and the door to open slightly again.

She stares at us for a few seconds before speaking. "My brothers aren't dark blue..."

"We... got stronger and this was a side effect. I assure you, it is us, Ironhoof and Thunderhorn," I reply.

She stares at us for a few seconds and then asks. "What happened on my tenth birthday..."

I frown and then sigh. "We came home to give you a present and mother some coin, but father refused to let us in. We ended up fighting and he left us all. I gave you our presents and enough coin to last for a few years, we stayed for a few days and then left to get more coin for you and mother," I reply.

her eyes widen and she opens the door and hugs my leg. "It is you!" she says and then hugs Thunderhorn's leg.

"Aye, is Mother inside?" I say gently and ask her.

She looks back at me and nodded. "She's in the back making some more blankets for the neighbours," she replies and runs back into the house.

Thunderhorn chuckles and follows her in with me behind him.

The house is just as I remember it. A staircase to the right leading up to three bedrooms, the fireplace in the centre surrounded by plain cushions made by mother. Shelves with family heirlooms and trinkets on the walls, along with two old and weathered axes on display.

"Mama! Iron and Thunder are back!" we hear her shout.

I can hear the sound of a chair scrape on the floor as the back door opens. Our Mother walks through, a cane in her left hand due to a leg injury and wearing a soft comfortable grey robe. Her fur is a light brown and her horns a cream colour, eyes green and a steel ring in her nose.

She looks at us in shock before looking at Heartsong. "Sweetheart, where are your brothers and who are they?" she asks in confusion.

Heartsong explains what we told her and Mother looks surprised. She then leads us to the fire pit and we all sit around it where Thunder and I begin recalling everything that happened since we last met.

I'm sitting on a chair within the Arena's main office where Onyx is laid out on a couch, still out cold and with a grin on her face. The announcer who is named Iron Lungs, is nervously standing behind a desk with a large scarred black furred male Minotaur named Gladius, sitting at said desk. His left horn is snapped off at the middle, and his right eye is a milky white colour while his left is brown.

"To think the Chieftain lost... I suppose there's a first time for everything," he says and taps a finger on his desk while looking at Onyx who is giggling and cuddling a pillow. He also has a mug of some strong smelling alcoholic drink.

"I've lost a couple of times during my sixty plus years in Tartarus. But I learn from my failures and defeats and improve myself from them," I comment and yawn.

"Yes, just as any warrior does, you fought very well, and your experience in battle showed. To be honest, after you've told me what you just did to the Chieftain, I would like to see a rematch. How well would you do against her with her increase of power?" he asks me and takes a chug of his drink.

"I'm not ashamed to admit that she's physically stronger than me now, but my true power comes from my Darkfire and shadow spells. I could easily just slip into the shadow realm and sneak up behind her with a lethal blow without her ever knowing," I shrug in reply.

He goes to speak but a groan from Onyx gets all our attention as she sits up, still hugging the pillow.

"Where am I?" she asks.

"Chieftain Onyx, you're in my office," Gladius replies and finishes his drink.

She looks around and her gaze lands on me, a mild barely noticeable blush colours her black fur. She shakes her head and looks her body over, flexing her fingers and muscles.

I stand up and walk over to her, getting her attention. "So, ready to sign that treaty or do you need more time to examine your new body?" I ask her.

She looks up at me and sighs. "Might as well get this over with, I have other questions I'd like to ask," she says as she stands up, followed by stretching her limbs.

I chuckle as I follow her to the door. "You're not the only one with questions!" I reply.
