Reincarnation

Bob was spreading cancerous memes and opinions on social media and offending a lot of people. It wasn't the first time he was doing this kind of sh*t. But unknown to him, someone who he would never want to offend was offended by his cancerous opinion and that being directly him.

Bob was swimming in void when suddenly he heated a voice.

"You like spreading cancer, don't you? Now I'm going to make you tumor of a world class cancer. Now off you go." The voice said.

[ Danzo is world class cancer and Bob will reincarnate as his tumor]

Bob's soul was sucked in a space crack and was sent to unknown world.

-------------------

Outskirts of konoha in an underground base

An old man was happily grinning like a kid in his birthday party. He had bandages on his right eye and right arm. He was none other than Danzo Shimura the biggest cancer in Naruto world.

"Sensei, I turned your dream into a reality, now the uchiha clan is gone for good. Wahahahah." Danzo said while acting like a madman.

The reason Danzo was so happy that he succeeded in annihilation of uchiha clan. He achieved the goal that his sensei Tobirama Senju The Racist only dreamed of. He forced uchiha clan to coup and killed anyone who got in his way like a certain uchiha who wanted to use his Mangekyu ability on uchiha clan so that they wouldn't coup against their village. His good peace loving old friend hiruzen sent him his brainwashed will of fire puppet to him(Danzo). And Danzo used him as a scape goat in uchiha massacre.

"All uchiha are fools. And their sharingan is for me to use. Buhahahah."

Unknown to Danzo, because he used Hashirama Senju's cells on his body and sharingan, it caused a cancer sell to form in his body.

And this cancer cell had its own Soul. It was none other than Bob. He was listening to this madman's banking for a while now.

(1st person POV)

Bob Tumor was reborn just now and was confused as to where he was when started hearing some japanese shouting out loud and laughing. Bob didn't know japanese language. He wasn't that much of a weeb who would learn japanese just to watch anime.

Bob after being reincarnated got a few abilities. First of he can posses anyone's body he wants to by going inside of them. So he used his ability and possessed the body of his host.

Bob looked around trying to figure out his situation. He was in a room with only candles and bed. He assumed his host was about to sleep while laughing for some reason. Bob accessed the mind of his host and read his memories. He learned japanese language fairly quickly. While looking at the host's memories, Bob was disgusted by them. He was actually in the body of Danzo Shimura. Danzo did many unspeakable things for his greed of power. And he recently caused Uchiha massacre.

"So, I'm at the time of uchiha massacre. And naruto, sasuke are around age 7. well I should use my other abilities to make myself stronger." Bob said

"let's use my skill absorption. I can can absorb anything. Like the cells of another person and gaining their abilities and chakra from anyone. and I'm going to leave dry danzo off his chakra. and absorb all sharingan and hashirama cells and their own unique chakra." Bob started absorbing everything in himself or itself. After this Bob left danzo's dryed body and looked at himself. He looked like a black substance just like zetsu but without a dance. He was just complete black stuff.

Bob collected himself and went inside the ground. it was fairly easy to travel in earth after absorbing Hashirama's cells. He went to. konoha's direction.

He wanted to take a body of a student from the academy, precisely body of someone who is in class 1A.
