Katakuri Zamora was a prodigy. He graduated from high school at 9 years old found the cure to cancer in a grace period that rarely happens between wars while also serving the military being an expert marksman, amazing fighter, great spy, and having access to area 51 for expirements on the rare extraterrestrial lifeforms they had there. 

Katakuri got bored of his life in the military and left after his contract ended but to keep the secret of aliens from sliplimg they assassinated Katakuri while he was finishing One Piece. His favorite character was Katakuri because of their similarities

Katakuri: "Man thats all the episodes I should rewatch Naru-" 

He couldn't finish because a bullet was lodged in his brain from an expert sniper hired by the government. Katakuri woke up in a vast black space he looked sround but all he saw was black and after what seemed like a few hours (But was actually a few millenia) of walking he found a throneroom with a man who looked to be in his mid 30s

Katakuri: "Hello how are you and who are you if I may ask?" 

He said politely

???: "Finally a well mannered soul. Well young man you have died.I am the person you humans call god"

Katakuri was a little shocked but after seeing aliens he knew there could be a god in this world

Katakuri: "What am I doing here if I may ask?"

God: "Well you have double infinite karmic points because you found a cure that only 1 other person in history could figure out but he wouldn't anyways I'm going to grant you any wish you have. Go"

Katakuri: "I want the Mochi Mochi no mi, Tremor Tremor no mi, Gomu Gomu no mi (For blunt attacks and electricity), Goro Goro no Mi, Ope Ope no mi, Yami Yami no mi, Pika Pika no mi, Magu Magu no mo, Hie Hie no mi, The phoenix fruit, and Kaidos dragon fruit please with no weaknesses. Also a system with infinite system points "

God: "Granted anything else?"

Katakuri: "Instant mastery, Memories from my previous life, every Mangekyou Sharingan upgraded to eternal with 10x their normal power and 100x more powerful Rinnegan with all 7 rings, A zanpaktou , infinite stamina, luck, int, wis, strength, durability, speed, endurance, energy of all kinds, and all of the speedsters speed forces combined, and A super amped up majin buu regeneration which is aslong as I have a soul I can regenerate and I don't age, no poison will affect me,"

God: "Anything more like races bloodlines transmigration or reincarnation?"

Katakuri: "I want to be a Archangel combined with the Origin demon and transmigration please"

God:"Okay what world and time?"

Katakuri: "DC Arrowverse 1 year before the Accelerator explosion"

God: "What do you want to look like?"

Katakuri: "Katakuri from One Piece anime also I want to be 19 years old please and thank you."

God: "One greedy human aren't you. Well okay but instant mastery will awaken devil fruits as soon as you use them so be careful and train all of them, goodbye."

Katakuri: "Goodbye god"

Katakuri said as he walked through the portal

-Arrowverse at a soundproofed apartment-

A portal opened out of nowhere a 12 feet tall (A/N: he chose to lower his size because no apartment can hold a 16 foot tall person) with spikey crimson red hair, fangs covered by a scarf, Colorful Tattoos on his chest and arm, and black pants stepped through it

Katakuri: "He prepared an apartment for me how nice of him."

He said with real sincerity in his voice

Katakuri: "Wait!"

He turned his left arm into Magma his right arm into lightning his chest into mochi his left leg into light and right leg into darkness he then sprouted blue wings made of flames from his back and transformed his head into a dragon at that time all the knowledge of the fruits came to you and you awakened all of them

Katakuri: "Wow he went through with his word!"

He transform back and catch a wiff of yourself and you smelled horrible

Katakuri: "Guess a clean body wasn't in the transmigrate package

He laughed and took a shower when he realized he didn't have shampoo, conditioner or a towel then he remembered he had a system

Kata: "Hey system Im calling you Nami can you buy the best shampoo and conditioner please along with your softest towel please."

Nami: [Done]

A bottle of shampoo, conditioner and a towel appeared I went in and turned on the shower getting sprayed by hot water felt so refreshing when he smelled the shampoo and conditioner they smelled like honey which according to the system the shampoo and conditioner smell different to everyone when he got out he picked up the towel and it felt like he was using the worlds nicest fabric in a towel he then bought a blanket which was ven softer than the towel somehow he fell asleep... and woke up 10 months later because he was awake for millenia he figured out he didn't need food but still enjoyed it when I realized there was only a couple of months until the start of The Flash I immediately started training I mastered my tremor fruit awakening it making vibrations bend to my will meaning if The Flash tried to fight me and phase I would just change the vibrations he used and make him solid again.

I had gotten a job at S.T.A.R Labs to help Barry 

-Months later-

Barry woke up finally
