He had been reincarnated... as an obscurus!? Inside Harry Potter's body, no less. He's Harry Potter's obscurus, not Harry Potter himself. He'll manage, somehow. First thing first, He'd need to get his host out of the Dursley. Cover made by Revon Zev (This book's author). Also on Ao3, FFn, Scribble Hub, and Wattpad. Spanish translation by Nasu954 on Wattpad.
'WHAT!? I'm IN HARRY POTTER!?' he thought as he heard Harry called his uncle "Uncle Vernon" then being told to fetch the newspaper.
'How is that even possible!? But as a what? Obviously not as Harry Potter.' He could use Harry's senses, but he wasn't Harry Potter. Was he Harry Potter's magic, then? He had read "reincarnated as mana stone" fictions, but not as someone's magic. Then what was he siphoning right now and the red wisp he ate. Wait, wait, wait. Was that red wisp Vol— No, don't think about it. Don't think about it!
'That would mean, that —' he glanced at the green wisp, '— is Harry Potter's soul!' he stopped siphoning upon Harry's soul but found he couldn't retract his strands and could only slow the process. 'Damn it!'
He tried to rise his arm to see what he was. He… got four arms. What the 'ell? Wait, no. One set was Harry's, fetching the newspaper on the porch; the other black wispy stands arms was his. Well, before Harry had suppressed them.
He knew what he was now. Fantastic Beast movies made sure of it. He. Was. An. Obscurus. WHAT!? Him? A parasite? He couldn't believe it. Except that it had already happened, and the obscurial was Harry Potter. 'That's just… that's just insane!' He had skim over a fiction about being reincarnated as a virus… but being involved in one of those wacky reincarnation stories? What. The. Heck! He wanted the promised heaven, not what ever this was. Did he anger off the reincarnation god per chance? 'ROB! I'm sorry alright! Please! What ever I did, I'm sorry!'
*Ding*
The sound! It was like those systems sound! Thank you… R… o… b… Gosh damn it! You damn toaster! When did Harry even get to the kitchen!? He winded his arm and strike the toaster in Harry's vision, piercing it with the sharp end of his strands like a spear. He sweat dropped. 'Oh shite.'
Harry was having a panic attack, shite. A-alright, how does he go about it now? Panicking Harry, check. Toaster with a hole in the middle, check. Breakfast—the Dursley grumpiest time of the day—check. That wasn't a good list. Right. He was an obscurus. Magic the problem away. How? He hadn't read a single magical totem and hadn't done any magic—besides materializing tentacles.
Right. Right. He had a list. First thing first, dealing with Harry. If he remembered it correctly, Credence held somewhat of a control over his mindless obscurial, does that apply with the reverse? He could say Harry was pretty mindless right about now. Like they say, there's no time like the present.
Okay, one down, two to go. Gaping toaster problem. Credence's obscurial was invisible for when it doesn't want to be visible, right? That obscurial didn't phase through walls though, it obliterated them. Not what he wanted. He will flow through the crevices then. He grabbed the broken toaster. Finger cross he won't break the wooden walls. After he had gone outside, he did the same with the neighbor's wall and switched the toasters. Then going back the same way he got in anddd done! He did a ta-da pose and a second later facepalm. He could've gone through the window!
Now he needed to serve the ham and egg sandwich. He rubbed his nose bridge. Ugh, he wanted to kill them. Not yet. Not yet. If Harry and him were to share a body together, then he would rather it to be of Harry's own volition. Except in cases like panic attacks and sleeping, Harry could just suppress him. He doesn't want to be suppressed while flying a death distance from the ground. It would end as well as when Harry had made out with a bludger… minus a spell from an incompetent copy-n-paste author/teacher.
He brought the plate with sandwiches and three glass of tea to the Dursley. When he was bought over the mugs, he saw his glowing toxic green pupil and black sclera reflected on the glass. He kept looking at the floor as not to alert the Dursley. The plate and mugs were set and were about to go back to the cupboard before Vernon yelled, "There is no cheese in these sandwiches, Boy! Get back here!" He got back to Vernon.
Vernon slapped him on his cheek. It stings. Harry and him did share a body, that means Harry's pain was his pain. The pains were numbed down before he took control of Harry's body, but the pain was felt in its full glory after he took control. Be patient. He and Harry would get their revenge, just not now. He needed to explain to Harry what he was today.
On the way to school on the Dursley's car, Harry woke up from a nap after Harry got a panic attack. The obscurus relinquish control of the body back to its owner and ruminate on when he should give the explanation.
A/N:
Reincarnated as Harry Potter's magic, anyone?
