I am here with a drabbles/one-shot series! This is just a silly story where Obito finds himself stuck in the MHA universe. There's very few Obito crossovers so I thought I'd make one, he's one of my favourite Naruto characters and deserves more love.

For those of you that are waiting for my Avatar story to update, that will take a little bit (most likely until sometime next week) since I have some personal stuff that's come up. In the meantime, I hope you'll have a laugh or two at this less serious story. I'll update this whenever the fancy strikes me, really.

As always, if you have any thoughts/critiques/ideas, please feel free to leave a review or to PM me.

Chapter 1: How Not to Use Kamui

Obito Uchiha allowed himself to frown from behind his mask as he felt his body slide into his own personal dimension—Kamui, as he had come to call it. It was a sanctuary from the madness that was his own plan, his own actions.

This horizonless, almost dead world resonated with him on a deep level. Here, in this world inhabited only by the floating rectangles of earth, inhabited only by himself, Obito could truly relax. Only he could interact with it. Here, nothing could hurt him, nothing could touch him. In the real world, he could not allow himself even a moment of respite. His shinobi instincts would not allow it.

Here, he was safe.

Flipping his mask up, he sighed in contentment as he reclined on a small hammock he had set up just for that purpose.

The benefits of having your own dimension, I suppose.

Reaching for a box of dango (something he would never, ever admit to actually enjoying) he was rudely interrupted as a small, forearm-sized missile suddenly swirled into existence right in front of his face.

What the fu—

Obito instinctively leapt out of the way of a strike as he reached for kunai that he simply did not have.

"Wow! That's a really cool quirk! You're like a ninja!"

He was currently perched on the side of a wall, and the so-called "attack" had been a child that was trying to poke his mask. The boy was wearing a bright red, blue, and white costume with yellow boots and gloves. He had strange, almost rabbit-like protrusions coming from a yellow headband.

"You don't look like any hero I've ever heard of…" the boy said suspiciously. Suddenly, his eyes brightened as he snapped his fingers.

"I know! You must be here for the AnimeCon! They changed venues with the HeroCon last minute, though. They're a couple of blocks over," the young boy said as he admired Obito's strange, orange, swirly mask and his fancy robes. "Hey, what character are you cosplaying as? You look really cool."

Cause play? Enemy con? Hero con? What in Kami's name are those?

Taking a glimpse of his odd surroundings, Obito only became more confused. Peculiar smells and sounds assaulted his senses.

Am I in a genjutsu?

Something like that was highly unlikely, given his Mangekyou Sharingan. His single eye span wildly as he looked for any giveaway that he was caught in a genjutsu. Clapping his hands, expelling some chakra - just in case - he felt his analytical mind race.

This must be the action of enemy shinobi.

Ignoring the child, he ran up the side of the building, quickly reaching the top.

"Aw man… I didn't get the name of the anime he's from," the child pouted sadly as the man vanished.

Reaching the top, his confusion doubled. Gazing down at what could only be described as a gigantic village, his mind catalogued all that he saw. Strange metal boxes - with people of all things inside them—scurried about on a surface so smooth it could only have been made with earth-style jutsu. Buildings—larger than the ones in Amagakure—made of glass and steel towered higher than any man-made structure he had ever seen. Strangely dressed people were gathered around other strangely dressed people, while other more bland looking people waited for some invisible signal to cross the smooth surfaces, somehow not getting flattened by the rather quick metal boxes.

He could not be in a genjutsu. This—whatever it was—was too absurd to be something any shinobi could come up with, surely.

He allowed himself to be pulled into Kamui as he tried to process what he had seen. Instantly, he was met with his ruined hammock and absolutely demolished stash of dango. He cursed as he pinched his mask in frustration.

Right. I was nearly blown up.

Fucking Kakashi.

Finally processing what must have happened, Obito felt some weight vanish from his shoulders as he arrived at the only possible, logical conclusion.

I survived the blast, but due to it interrupting my well-deserved rest I went into shock and had a horrible nightmare.

Yes. It's the only explanation.

If he was right—which he was—then going out of Kamui would take him back to Akatsuki headquarters. Swirling both into and out of his eye, all cognitive thought halted as his theory was disproved faster than he had formed it.

He was back at the same place he had decided was a nightmare.

Fuck.

Fuck fuck fuck fuck fu—

Ok. Calm down Obito. What do I do now?

Recalling the one-sided conversation, he eventually came to a conclusion.

I need to find this 'enemy con' and destroy them. It's not like I'm in an alternate dimension, or anything. That would be beyond absurd.

Obviously, Amegakure had been renovated in his absence, and that child had been a shinobi of some sort that Pain had neglected to tell him about. Or maybe he was in a twentieth hidden village, and not in Amegakure at all?

Of course. He was trying to tell me about the enemy. But what the hell is a cause play?

Some sort of jutsu? Code, maybe?

Whatever it was, it did not matter. Just like the fact that he could not return to the Akatsuki headquarters did not matter.

To say Shinji Nishiya, better known as Kamui Woods, was unhappy would be an understatement. He had been enjoying his day—minding his own damned business, mind you—until Mt. Lady had all but dragged him from his day off and to the local HeroCon.

"Takeyama… did you really drag me out here for this?"

The two of them were in their hero costumes and attending the outdoor convention, their costumes and somewhat lesser notoriety—compared to, say, All Might—allowed them to blend in rather nicely with all the regular people in their cosplays.

She whirled, her eyes sparkling. "What do you mean 'drag me out here for all this'? This is amazing! Look! They even have a Mt. Lady plushie!" She pointed to a disturbingly accurate, life-sized Mt. Lady pillow.

"Wow, they even got my cup size correct!" she exclaimed as she examined it more closely.

"Errr…. I don't think that's what you think it is…" Nishiya reluctantly pointed out.

She ignored him as she continued to gush over a body pillow.

And to think I could be at my apartment, enjoying a nice meal, in peace.

He sighed.

The first thing any shinobi worth his salt would do in this situation would be to gather information. That is exactly what Obito did. Switching to his persona of Tobi, he teleported down and into a narrow crevice between two larger buildings. While most shinobi would be 'sneaky' or 'stealthy' or even 'subtle' with their information gathering techniques, Obito preferred to be slightly more direct.

Leaping out from the alleyway, Tobi attempted to grasp the nearest person and shake them.

"Senpai, senpai, please! Tobi needs your help!"

The wooden man in a blue suit nimbly caught the clearly insane man in a wooden prison.

"Wait! Senpai, don't hurt Tobi!" Tobi yelled in panic as he was bound hand and foot.

"What… what are you doing?" Kamui couldn't help but ask, confused. Was the man a villain of some sort? His getup was strange, to say the least. A colourful swirling mask, and black robes with red clouds dotted somewhat randomly along it. Spiky black-brown hair protruded up and all around from his head.

He certainly wasn't doing anything villainous.

"Kamui! Let him down. Obviously, he's here for my autograph," Mt. Lady announced, crossing her arms under her bust.

"Hehe… Tobi doesn't know the funny lady… Tobi needs help!" Tobi said sheepishly before shouting.

Kamui Woods ignored his outraged partner as he let the troubled man down. Tobi hopped around, agitated, until he put Kamui between himself and the deranged woman. Kamui felt himself enter what he and other pro heroes called "hero mode". The man was obviously very, very distressed. There was no telling what kind of help he would have to give.

It's my duty to help those in need.

"What? Is it villains? Are you hurt? Are—"

"Tobi is lost! Tobi woke up and he was gone!" Tobi interrupted, raising his arms up before collapsing on the ground.

"You lost a friend?"

"No… Tobi has no friends. Tobi is lost. Tobi doesn't know where he is…" he crooned, rolling over onto his back.

Kamui Woods didn't know what to do. Hero school had taught him many things. How to fight. How to comfort and rescue hostages. How to try and de-escalate dangerous situations.

They had not taught him what to do with someone that talked about themself in the third person.

"You're… lost?" Kamui Woods asked, at a loss for words.

"Yes, Tobi is very, very lost." Tobi nodded sadly, his shrill voice managing to sound quite depressed.

"You're in Musutafu, Japan, you big idiot! And I'll have you know I'm not a funny lady!" Mt. Lady yelled from behind her partner.

"Stay away from me!" Tobi yelled in terror. "Don't hurt Tobi!"

"Takeyama, calm down. You're scaring him." Kamui turned back to the man with the swirly mask. "She won't hurt you. Please, calm down. What can I do to help?"

"You would help Tobi?" Tobi asked, amazed.

"Yes," Kamui answered patiently.

"Do you know where the enemy con is, senpai?"

"Enemy… what?"

"Don't be stupid. He means the AnimeCon."

Kamui looked at his partner, his eyebrows bunching up in confusion.

"The AnimeCon! You know, like the HeroCon, but for anime? It's obvious, look at his costume. Anime is all the rage with kids, you know how it is."

"Scary-senpai knows where the enemy con is?" Tobi asked, peeking over Kamui's shoulder.

"Of course I do. It's the next block over," she said with a large smile as she pointed towards its general location.

"Thank you, scary-senpai and senpai! Tobi is grateful!"

Tobi ran away as quickly as he had appeared, before turning the corner and disappearing.

"What a strange guy…" Kamui said, bewildered.

"A big idiot is what he is. Probably wanted the attention of two big-shot heroes," Takeyama said, a little too loudly.

Their earlier conversation had attracted a small audience. That same audience that were now quickly realising that in their midst were not two fellow cosplayers - but rather, two rather popular up-and-coming heroes.

Kamui Woods cursed as they were swarmed by eager fans.
