A/N: Guess who's back? Back again! Yes it is your boy and I know you all are upset about the wait. Don't worry. Next time will be longer.

It had only been a couple days since Izuku gained One For All. He didn't feel any different at first and he began to think All Might pranked him. It didn't help with the fact Shoto teased him about it continuously. It was really starting to get to him.

"Hey! Knock it off already, will you?!" Izuku yelled.

Shoto rose his hands in defense.

"Calm down Izuku!" Shoto sweat dropped.

Izuku punched Shoto in the shoulder and grunted. It wasn't all that hard, but Shoto still rubbed it regardless. They were scrolling through the channels in order to find something interesting to watch, but it was either news networks that were talking about the weather or kid shows that tested their patience like Dora The Explorer. Izuku was about to throw the remote at the TV until he found something actually interesting. The name of the show was My Sky High Hero Academia. It seemed pretty intriguing so he decided to give it a chance. Izuku and Shoto became pretty invested in the plot of the show although the two tone haired boy pointed out plot holes in the show.

Izuku just looked at his brother with a blank stare and dragged his finger over his throat. Shoto knew exactly what Izuku meant and stopped talking so much. Izuku looked back at the TV and the more episodes he binge watched, the more excited he became. Their father walked into the living room with a bowl of popcorn in his hands. He was only wearing a pair of boxers and an undershirt. He walked past Izuku and Shoto, but swiftly snatched the remote out of Izuku's hands. Izuku looked at his father in shock. The man sat down on his recliner, got comfortable, changed the channel, and started eating the popcorn.

Enji had laid the remote on the armrest. Izuku saw this and immediately walked over to grab the remote. Enji wasn't having any of that though and swiped the remote away from Izuku's grasp. He looked at his son and smiled wickedly at the boy. He wagged his finger at the curly haired boy.

"No no no. The rugby game is going to be on in the next 10 minutes. It's the finals too! I don't want to miss a moment of it! I even took off work today." Endeavor spoke.

"I was watching something though."

"Too bad. TV rots your brain anyway."

Izuku's jaw dropped when he heard this. The hypocrisy. Not only that, but he and Shoto were watching an epic fight scene. The main character was fighting a crazed villain who had these weird muscle tendons covering their arms. The MC broke his arm, but he kept pushing forward. He was at the edge of his seat, but his father just had to walk in and interrupt. He wanted to continue watching it though and tried thinking of a way to gain back the TV. That's when it hit him.

"Let's spar."

Endeavor was still watching the TV, but he became silent.

"Whoever wins get the TV for the rest of the 2 hours and a half." Izuku stated.

Endeavor turned off the TV when he heard this. He turned his neck so fast it was a surprise he didn't get whiplash.

"Did you say spar?! And whoever wins gets the TV?!" Endeavor yelled, excitedly.

He jumped out of his seat and spilled the popcorn on the floor. He looked down at the mess he made and waved it off.

"I'll clean it up later." He said.

He looked back at his sons and rubbed his hands together. He smiled creepily. He seemed way too excited for this.

"Um, yeah."

Izuku realized what he had just said and wished he could have went back in time. Why? To slap himself for his idiocy. This was going to be a nightmare. He could tell.

Endeavor grabbed Izuku and Shoto's collars. He dragged the two over to the training room. He himself changed into more proper clothing apparel for the occasion and got into a fighting stance.

"Wait. Why was I dragged here?" Shoto questioned.

He was also in a fighting stance and same for Izuku, but that didn't quench his curiosity. Endeavor looked at Shoto and smiled at the boy sweetly.

"It's good for your development." He answered,

Shoto looked at his father with a deadpan face. Was this man serious right now? Of all the excuses, he really decided to use that. He wanted to slap the man just for saying that, but he looked over to Izuku. He whispered into Izuku's ear.

"Look. That One For All power better come in soon or I will be severely upset with you."

Izuku just nervously laughed at his brother. He knew he screwed up big time especially with how serious their father was about sparring. It would be good to test out his abilities though. If he were to suddenly manifest One For All through an enhancement of his abilities at any time, against a man like Endeavor would be a good time for it to happen.

"Get into your fighting stances boys!" Endeavor roared.

Endeavor got into a sort of boxing stance while Shoto took up the form of a drunk monkey. Izuku used the Capoeira form. Endeavor smirked and charged at the two. Shoto immediately shot a barrage of ice at his father. He was hoping to quickly overwhelm the man, but he jumped over it and glided down. He didn't have his fire covering his body like he usually would when he was in costume because of Izuku's unique attributes with his Quirk. Speaking of Izuku, the boy formed a fireball in one of his hands and threw it at his father. Endeavor was still in midair so he couldn't dodge it. Instead, he canceled out the effects by shooting his own fire blast at the fireball. They clashed together and faded away.

Endeavor dropped down on the ground and tried to punch Shoto, but the boy blocked the attack via forming ice around the older man's arm. Shoto cracked a slight grin for a split second before he was punched by the man's other arm. He grabbed his jaw in pain and looked at Izuku. Izuku prepared an arrow of fire and launched it at Enji. Enji saw it coming from a mile away though. He nudged his body to the side and ran at Izuku. Shoto froze his father's leg though. It was quickly melting though.

Shoto managed to slow down his father though. That was the important part. He managed to throw off his dad's balance for a couple of seconds while the ice melted. He shot a fire enhanced punch at Endeavor. It hit the man square in the jaw. It hurt, but Endeavor smiled viciously. He turned up the heat in his flames and the ice melted even faster than before. It didn't take much longer for Endeavor to barge out of the ice and rampage again. This was when Izuku came into the fight though.

He grabbed his father's wrist and wrapped his arm around the hell flame hero's throat. He was in his full phoenix form. Completely covered in fire. He was trying to quickly subdue him by raising his body temperature enough to where it could disorient him. Then, they could hopefully pin him down and be done with this, but the older man was having none of it.

He shook Izuku off of him and punched the boy in the gut. There was enough force in it to cause Izuku to lose his grip on the man's fist. Izuku was about to hit the ground, but he quickly did a handstand. He used the momentum in order to do a spinning kick. He was able to form what looked like a tiger's face albeit a bit sloppy since he was using his legs. He projected the tiger face at Endeavor and kicked the man as well.

He threw himself back on his feet and shot fire bolts at Endeavor. Shoto shot flames at his father as well. They weren't well constructed like his brother's but they still got the job done. Endeavor just laughed and charged at them. He wasn't slowing down at all. He stretched his arms out and was about to pin the boys down to the ground. Izuku panicked.

It was at that moment something unexpected happened. Izuku released a huge wave of blue flames at his father. Everyone's eyes widened when they saw this. Izuku's eyes began to twitch when he saw the blue flames. He never used these flames and especially to such a level. He usually wasn't even able to create such a mass of flames unless he overdosed on his consumption of flames.

The force from the flames sent Endeavor flying back and hitting the wall. He didn't even bother moving. He was too shocked to move. He just sat there in disbelief. He was rather impressed. He didn't know Izuku had it in him especially with his past trauma concerning blue flames. It was the reason why they tried to avoid using such a high amount of firepower while Izuku was around.

Shoto walked over to Izuku and whispered to him.

"What was that just now? You never use blue flames and since when have you been able to use your fire at such a widespread amount? W-Was that maybe One For All taking place?"

"I-I think so. I-I-I don't know!"

Izuku clutched his head in frustration. He was confused. He didn't know what was going on. The rare instances he ever used those flames, it usually was far more focused rather than spread out and he would have some bad side effects. He would feel completely drained of energy, experience bad headaches, distorted vision, and sometimes even worse. He experienced none of these though. Instead, he felt a tingling sensation around his arms and his legs were a bit wobbly. He felt like he had just finished an extreme workout session in the gym.

Not necessarily about to faint, but just weak and exhausted. He had a bit of a headache, but nothing he couldn't handle. He didn't understand the meaning of it so his only conclusion was that it had something to do with the Quirk All Might gave him. He supposed it wasn't a hoax after all.
