My fault (The true story of Ultron and a buncha chaos)

War Preparations

POV: Peter

Mr. Stark found me on the roof of the school and made me go back. So instead of telling him why I'd been there, I asked him if I could 3-D print 457 plastic zebras.

That's how I ended up in Mr. Starks lab, waiting for the 3-D printer to 3-D print all 457 plastic zebras.

"So... what's up, kid?" he asked, spinning in a swivel chair. I shrugged, watching the printer.

"Not much... school, decathlon, this, which is really really great Mr. Stark, but you know all about this, so..."

"Nice. What do you need plastic zebras for?" he asked, stopping spinning to give me a look. I took the second one out of the printer and pushed start again.

"I don't know. School? It's April Fools tomorrow, so-"

"Right. And you told Loki, didn't you?"

"Yeah... I'm sure he won't break any laws though, Mr. Stark," I said, setting the next zebra on the stack. He raised an eyebrow at me.

"You're sure that Loki won't break any laws," he replied.

"For the most part?" I said, trying to bottle-flip a zebra. "At least the important ones."

"And where are you getting this info from?" he asked, giving me some kind of look I wasn't paying attention to because I kept my eyes on the zebras. "Loki himself?"

"Kind of... Maybe?" I said, earning myself more and more Stark trust.

"Nice going, kid," he said, shrugging with a sarcastic smile. "Let's just hope my arc reactors don't shoot confetti by the end of this."

"I think it'd be easier to get my web-shooters to do that, Mr. Stark," I said.

"Either way... we always could plan a counter-strike... You up for it?" He threw me a pen, which I caught, with the help of spider-sense.

"Sure, Mr. Stark," I said, knocking over my zebra tower. "Do you have a plan already or..."

"I'm not sure if you know this, but I don't exactly do plans," he replied, grinning. "Which means... let's see what you've got, kid."

"Oh... ok?" I pulled up some holograms, not sure what I'd actually do with them. "I guess... do you have his helmet?"

"Right here. Thor was going to give it to him... eventually," he said, tossing it over to me. I caught it,  noting that man those horns were sharp. "So. There you are. Plan?"

"Well..." I said, drawing out the word. "We could... mess with it or something?"

"Okay," he said, pushing his chair over and pulling up another set of holograms. "So... give me your vision, kid. Doesn't have to be pretty."

"Well... basically... these are sharp, right?" I said, poking my finger on one of the horns. "So... we could impale something on it, like-" I took a zebra and stuck it on. "-That's cool, right?"

"It's a start," he replied, taking it. "We could get some sort of green-screen thing over the whole thing, and make it all a zebra."

"Or... we could make it a big rick-roll," I added. "Somehow."

"Nice. And what about Pietro?" He asked. Then, to my confused look, he added, "You know he's going to try something."

"Wanda could probably help with this one," I said. "Maybe... we could give him slow boots or something?"

"Something like that. You know what'd be really cool..." he said, snapping his fingers. "We could 3-D print a Mjolner, freak out Thor."

"Yes," I said, starting a Mjolnir with a box and a handle, then fine-tuning it to match Thor's hammer.

"For the slow boots... maybe we should just stick with some kind of sticky, really-high viscosity thing on his shoes..."

"Honey?" I suggested, but he shrugged that off.

"Eh, we don't want ants. Don't tell Scott I said that."

"Scott?"

"Weird guy, likes ants, helped us beat up some jerks at one time or another. Ant-Man," he said. "Either way, honey won't work. Plus, we probably need something thicker..."

"So... Basically glue with corn starch in it," I said, tweaking the hammer print. The zebras piled up next to the printer.

"I'll test it," Mr. Stark replied, pulling up a hologram. "I think... it'll work."

"This good?" I ask, spinning the holo-Mjolnir, which looked pretty much like the real thing to me. He studied it, pulling up a security camera.

"Find a good frame of the real one, for reference. Looks good to me, but just in case," he said, sliding over to me.

"I can take the search, young sir," Jarvis said, the screen flicking through to a hallway with the hammer flying past on a short loop. I paused it when it was in good view, tweaking the hologram to add the wacky triangle-loop kind of thing, and the leather handle.

"Thanks Jarvis," I said, re-doing the angle of the edges. When I was happy with the match, Mr. Stark cleared it to print.

After the other 342 zebras.

"Alright, here we are," he said, pressing a few buttons on some kind of scientific coffee machine and getting a thick and relatively invisible slime.

"How sticky is it?" I asked, looking at it over the zebra pile. He shrugged, putting on a glove and sticking his hand in.

"Really, really sticky," he said, pulling it out. The slime stretched, snapping the glove back down. In one quick movement, he got his hand out of the bucket. "Really, really, really sticky."

"Is it too much, or..." I asked as he took off the glove and yeeted it into a trash can.

"Nope. Perfect," he said, grinning. "Now. What about the zebras? There's plenty extra for whatever we need them for."

"Well... We have Captain Rogers, Mr. Bucky, Wanda, Vison, and... Mr. Barton and Ms. Romanoff."

"That's a lot of bases to cover. You up for a late night?"

"Sure, Mr. Stark!"

He grinned, pulling up the full hologram set-up.

"Nice. You want to make me a coffee?" he asked. "Any specific plans for anyone?"

"Is Bucky's arm magnetic? Wait- Is Loki's helmet magnetic?" I asked, turning on the coffee machine.

"Here, let's check," he said, gesturing for me to throw him a magnet from off the coffee cart. He caught it with one hand, slapping it onto one of the horns. It stuck. "What do you know, it's not pure gold."

"So we could just put a magnetic screen on there," I said, "on a little rick-roll gif."

"Sure, kid," he replied.

And that was just the beginning.
