So now:
Beithir vs Yayorozu.
Todoroky vs Bakugo.
Inasa vs (Beithir or Yayorozu, depends on who loses).
Beithir easily won against Yayorozu Momo, he was not in the mood of being a simp, so he just kicked her out of the arena without giving her a chance to try to create something. Some men in the audience were angry at him for kicking such a beautiful lady, but Beithir didn't care, for he believed in gender neutrality! He would kick all genders equally.
As for Todoroky and Bakugo... That fight was bad for very explosive, for Bakugo was angry that Todoroky didn't use his fire at all, so he just threw him out of the arena with a huge explosion. Inasa fought against Yayorozu Momo, he first asked her nicely to give up, but she just attacked him using a weapon she made, Inasa just sighed and used his wind to gently land her outside of the arena, making her automatically lose. Beithir was sure to call him simp later and teach him about gender equality, so when Inasa fights against women he will be sure to not underestimate them.
Now there was only Bakugo, Beithir, and Inasa.
So the system changed.
Inasa vs Bakugo.
Beithir vs Bakugo.
Inasa vs Beithir.
If you lose 2 fights, you are out. And Bakugo wasn't a fighter with great sustainability, for his quirk used a lot of his stamina if he used huge explosions as he did with his fight against Todoroky, so they gave half an hour of rest to all the participants, after that time they went back to the arena and decided who was going to fight who first. With the randomizing system, it was easy! Bakugo would fight against Inasa first, the loser of this fight would fight against Beithir, there was now also a time limit of 5 minutes, if the time went out it would be considered a draw.
Inasa had no mercy for Bakugo, he used all his strength to quickly controlled the wind and pushed Bakugo away, for four minutes Bakugo resisted the wind that was pushing him around, but he quickly was tired and could only fall as Inasa used his quirk to push him down outside of the arena. Bakugo should then fight against Beithir, however, he was too tired, he was given 15 minutes to rest. After 15 minutes Bakugo was ready to fight against Beithir... But the fight turned out to be a massacre. Beithir just kicked him out of the arena, the force behind his quick kick was enough to throw Bakugo away... Only one attack.
This somewhat humiliating? At least he lasted for about 4 minutes when fighting against Inasa! At least he got 3rd place...
Now the fight everyone was looking forward to! Beithir vs Inasa. This duo, childhood friends, and sparring partners that have been through torture (Aizawa's training) together are now going to fight seriously for the first time in their life! Inasa was so excited for this fight, for years he challenged Beithir to duels, but Beithir never took it seriously and he never won... It was a little depressing but also a good thing, for he had a goal that was to be stronger than Beithir.
When he looked at the other side of the arena, he saw him... Beithir. His 5'8 frame, blonde hair, and purple eyes looked at his soul. Inasa smiled and watched as Beithir's body changed, he was entering his hybrid state! Inasa instantly knew that Beithir was serious, because he only enters this state when he is ready to fight till death. Inasa spread his arms, soon the air around him began to gather and form some form of armor made of wind that looked more like a spiral of some kind of silver thread... In his hands, a silver sword made of wind appeared, he pointed it towards Beithir and slashed down.
What happened next could only be described as Beautiful. A huge tornado of silver wind started to spin around Beithir, really concentrating around his body, Beithir's transformation ended, and soon the tornado his body was broken by the sheer force of his transformation. A pair of red eyes, six black wings, and a snake-like bottom half body was presented to everyone. Beithir entered his [Hybrid Form: Giratina (Origin)]!
Inasa smiled like a maniac, he was looking forward to this! Adrenaline flowed through his veins, filling his body with a passion for the fight, Inasa always comments that heroes need passion and the will to fight strong opponents... Beithir compared him to a battle maniac, which Inasa negated several times, but now he understood why he is a battle maniac. Even though this form that Beithir has taken sent shivers down his spine just by looking at it, he couldn't help but want to fight!
Before Inasa could even blink, Beithir was in front of him. He was now 7'5 feet tall, he looked like a Naga from a fantasy novel, but with 6 dark wings made from energy, also his lower half snake body had spikes, just like his arms that transformed into two big spikes.
Beithir used his left arm like a lance and tried to attack Inasa, who dodged barely before using his quirk to push Beithir away to create distance between themselves. However, Beithir didn't let him run and pushed forward, using his half body to attack Inasa who used his sword to attack it, the wind sword cut through the scales, making Beithir scream as he unleashed a wave of purple-black spheres towards Inasa who could only protect himself using his wind.
The impact of the spheres and Inasa's shield created a minor explosion that scattered a small cloud of dust that blocked the vision of the battlefield but not for a long time. For Inasa flew outside of the cloud to the sky, using his quirk he gathered a huge amount of wind and sent a powerful blast of air down towards Beithir who used his wings to keep himself straight looking up. The blast of wind was so powerful that it pushed the concrete down, cracking it and breaking it into small pebbles, lucky them Cementos was repairing the arena.
