I Became Akainu from the Start and Unlocked Nuclear Fission Mode

He transmigrates into One Piece as Akainu at Marine Headquarters.

He obtains the Nuclear Explosion System.

His attacks carry the might of nuclear fission.

The Five Elders: "Akainu! Why did you mobilize so many troops from Headquarters without our authorization?"

Akainu: "I don't need to report everything to you. Also, I'm taking a crack unit to serve directly under me, at my command whenever I need them, as my personal army! You have two options."

"One: Follow my orders and pretend none of this ever happened."

"Two: Kick me out of Marine Headquarters, but I'll still take a crack unit with me, and they'll remain loyal to me."

"Oh, right. You do have a third option: send someone to kill me, to execute me. If you manage to kill me, fine. But if you don't, I'll burn your homes to the ground."
