Endless Adventure

I went towards my arena and Izuku was following me. When we arrived there I looked at the clock and then looked at Izuku I said, "I'll give you a whole minute to attack me. You could attack me using all your quirks!"

From the time I arrived to this world I never used my whole power. Even I don't know how powerful I'm. Overall power of My Hero characters is just little bit weaker than people from HunterxHunter world. Even thought I was weakened 300x I still had time to grow in this world. Every time I consumed someone my chimera ant form would get little bit stronger. I know that I'm stronger than I was in HunterxHunter world but don't know by how much.

Izuku looked at me and said, "Are you sure?"

After I nodded I felt little bit pain in my stomach I looked down and saw a fist touching my belly. He used this power again which looked like teleportation.

After seeing that his attack failed Izuku took a step back and his muscles started to get bigger. His body became super bulky twice of his original size. I again felt pain in my belly this time it was far more painful but still tolerable. I looked at him and said, "Is this all you got! You're just wasting your Quirk. Use everything you have right now. Only 23 seconds left!"

I could see he was really angry at me as his eyes were bloodshot and he was trembling from anger. He did nothing so I said, "Only 14 seconds left!"

After hearing my words he again took few steps back and he started to concentrate. Slowly his skin started to harden and look like scales. His size too got bigger. When only three seconds were left I felt an intense pain coming from my belly and I puked blood from my mouth. Even thought it was painful I still had almost no injury. Knowing that nothing could hurt me I looked at Izuku and said, "Time's up! It's time to pay!"

After I said that I send out a punch towards his stomach using my full power. Izuku was sent flying across the arena and crashed on a wall and broke it. The wall was created from the strongest metal in this world but it didn't stop Izuku as he kept flying. I created a portal and teleported next to the flying Izuku I again punched him and sent him back to the arena. There were two big holes in his body. When I looked at him I could see that those injuries were healing in an alarming pace. I really envy his regeneration powers.

Not wasting a moment I went towards him to steal his quirk but when I neared him I felt danger. That same moment I dodged to my left and it was a good idea because that place I stood in before now had a deep and long opening on the floor that went many kilometers long. I looked at Izuku and saw him stand up. Right now he was not himself. His body turned red just like berserk All Might. Many wh.i.p.s were coming out of his back. Those wh.i.p.s were darker than anything in this world. I again felt danger and dodged to my right. Like before the place I stood now had long opening on the floor that stretched many kilometers. That wasn't all as at the same time I was assaulted by many black wh.i.p.s from every side.

I protected myself using my hands to cover all my weaknesses. For few minutes I was assaulted by many wh.i.p.s and after it stopped I had many small cuts all over my body. I looked at Izuku and saw a red demon looking man. He looked at me and said, "Apologize! Say sorry that you killed All Might!"

I smiled and answered, "I'm sorry to tell you but I never apologize to the people who are weaker than me!" After I said that I ran up to Izuku and touched him. Slowly he went back to being a teenager and I bombarded him with punches. After that I stole his quirk and killed him.

"Rewind" is a really useful ability. With it I revinded Izuku's body to a state before transformation and killed him. I'm really lucky that I stole this quirk from Eri.

.....

In a white room an Old man with long and big white beard was sitting comfortably on his chair eating popcorns and drinking Pepsi as he watched something on his tv. But then he stopped for a minute and put down all his popcorns and drinks. He opened a portal and entered it. The portal led to a dark world.

There he walked around the dark world for a few minutes and arrived before the body of a teenage boy. He smiled and said, "If you survive this challenge for a 100 years. You can get your vengeance. This is a test but also and opportunity!"

.......

A year passed from a time I killed Izuku. I made his clone and implanted a parasite inside of him for his replacement. Soon he'll become a hero he always dreamt to be.

The "Redemption Act" was passed soon after Izuku's death. Many criminals would get their sentences shortened after the government take away their quirks. From this law I received millions of quirks. I used those quirks to improves my most used quirks. After I was sure I'm strongest person in the world I implanted parasites in every authoritative government official. Finally successfully taking over the world.

Also I fused my "Kleptomaniac", "One for All", "All for One", "Overhaul" and "Biokinesis" abilities and to create a new quirk. I called the new quirk "ULTIMATE". Even now I don't know fully what it can do. I still can use abilities of the fused Quirks. Also it has a new ability which I called "Limit Break". That ability is like an upgraded version of "Kleptomaniac". If I consume considerable amount of meat from certain race and understand them fully I could evolve my race.

Because I ate many people I evolved my race from human to arc human. This evolved human form was just weaker than my chimera ant form. Most likely this form Izuku would've achieved if he trained in "Biokinesis"

After unlocking "Limit Break" I knew which world I would travel to next. My Chimera Ant form was made from different animals and races. So to evolve it I have to first evolve many races to their evolved form. I chose the world with many races but also the place that wasn't more powerful than BNHA. The world I chose was One Piece world.
