"Congratulations, little brother. You have just taken your first step towards becoming someone truly great."
Izuku was shaking, knees bent and fists to his side. His hair was standing up, green lightning danced across his skin, and his veins were bulging, unimaginable power coursing through them. This power was One For All, being utilized correctly.
"How do you feel, Izuku?" I asked, impressed and slightly concerned.
"I don't know," he grunted. "It's hard to control it, but I feel strong."
"Good." I grinned. "Wanna try it out?"
Izuku grunted some more. "Yes!"
I got into a fighting stance, knees bent, and arms raised slightly. "Alright then, come at me."
Izuku calmed himself, focusing his power throughout his body. Air currents danced around him as the green lightning flashed fiercely. "Here I come!"
He dashed, kicking up rocks as the ground caved in where he stood. When he was close to me, he struck. "Ha!"
His punch connected, its power creating a shockwave that formed a large cloud of dust. When the dust settled, the aftermath was visible.
His punch had landed in my palm. Nothing had changed. Except, this time, there was a kaleidoscopic aura around my arm. I pushed it slightly. He gently flew backward, landing a few meters away.
"Hoh, that was quite powerful. Do you think you can keep that up?"
Izuku examined his body, impressed with his feats. He then looked at me with determined eyes. "Yes!"
"Good, because it's my turn!" I raised my backfoot and violently stomped it on the ground. "Dodge!" I thrust my palm forward.
He didn't dodge. A telekinetic wave emerged from my palm, moving at a fast speed before hitting him squarely in the chest. He flew back, violently hitting a distant tree.
"Hmmm, you should work on your reaction time. But, it seems your power does not only increase your attack power but your defense as well. very impressive."
I got into my stance. "Again!"
He attacked again. This time I ducked under his punch, punching him straight into his stomach. He flew in the air, his saliva flowing as he struggled to breathe. I did not let up, telekinetically grabbing him from the air and throwing him on the ground in front of me, causing it to crack slightly.
I jumped in the air, reaching a height of fifteen meters. Izuku was still recovering from my assault. "You better dodge this, Izuku!"
I dove feet first towards him, accelerating myself using my powers. A glowing blue streak lit up the dark forest as I rapidly approached my brother.
Panic filled his eyes as he quickly rolled to the side. He was just in time, as I landed where he was moments before with a loud bang, the resulting shockwave blowing him a few meters away.
"Nice dodge," I remarked. "Can you continue?"
"Y-yes!" He said as he struggled to get up, still that same determined look in his eyes.
And just like that, we continued our fight. Izuku attacked, I dodged or defended before retaliating with full force. Izuku got no hits that night, though he did come close once. A momentary lapse in my concentration, which I immediately compensated for by blasting him through a tree.
Thankfully, Izuku's defenses were quite excellent, and I held back quite a bit. So, when the sun finally started to rise, all he had retained were some admittedly large bruises, which I promptly healed. I did not want our mother complaining.
As we got up and prepared to go home before mother woke up, I asked one question which had arose during the sparring match.
"So, what are you going to call this new form of yours?"
Izuku thought for a bot before answering with an earnest face, complete with a smile and thumbs up. "It's called One For All: Full Cowl!"
I smiled, closing my eyes and nodding slowly.
"That's a terrible name."
