Chapter 13, everybody! What a lucky number. And now it's time for our musical number….

Minor correction from my discussion last chapter—my Dad uses AutoCAD at work. But! AutoCAD is part of the Autodesk library, so it still works. :)

The "Sleep is for the weak" line has seen appearances in some of my other BH6 fics—and Obake's coffee reaction is based on Goob's from Meet the Robinsons. In other news, Aunt Cass is now joining Baymax in scolding me on my sleep patterns. :| And I LIKE the Digimon movie fite me.

Also, two logistical issues: one, what was Heathcliff doing during the costume-making if he shuttled the kids back and forth, and two…the costumes are machined up in the garage and tested at Fred's place. Say they're at least a couple of blocks apart to account for the change in neighborhoods. HOW did these kids get everything transported without attracting attention guys please don't take notes from Gizmoduck PLEASE.

In other news…been looking at maps of San Francisco for my various BH6 fanfics—the island was never named in the movie but referred to as Akuma Island in the series. Angel Island is a real island in the San Fran Bay, and Alcatraz—the one everyone knows—has to exist in the BH6-verse because there's a poster of it in Hiro's bedroom. And in this 'verse at least, we get all three because I don't think even Disney has the budget to blow up important landmarks.

The Authverlord, thanks for the review! No problem—a fanfic writer that used to be on FFN did this all the time, so that kind of set the standard for answering reviews like this. :) Yes…when I started writing those two together they kind of understood each other and it kind of works. Ah, glad you like—I figure big campus like SFIT, not everyone knows everyone and with me figuring Obake as not a people-person he'd keep himself off of everyone's radar. Yes, this should be interesting….

They slept over at Fred's house before running back to the Hamada garage after breakfast—which wasn't that far, surprisingly, especially by limo.

"Okay, I could get used to this," Wasabi said, patting the cushions. "Everything's nice and clean, stitching looks good…."

"We have a sunroof," Fred put in. "Which, limo law, everyone has to try at least once."

Hiro crawled up upon his turn coming up, leaned on his elbows on the roof and lifted his neck to the wind, eyes lidded against the wind and the early morning light. Glance to the side when Obake climbed up, fresh bandaging on the side of his face courtesy of Baymax.

"Don't forget a woo-oo!" Fred added. "It's obligatory!"

Hiro obliged, shooting his arms up for good measure—elbowed Obake, who lifted a fist and waved it in a circle without enthusiasm.

"Hey," Hiro said, nudging him. "At least try?"

Obake glared at him, very pointedly mouthed you OWE me. All right, that was fair—drop back into the limo, Obake following a short moment later.

Aunt Cass had been called last night, told a big honking fib about how Fred had swung by the garage last night and invited them to the arcade and one thing led to the other and they all ended up sleeping over at Fred's place by the way can we sleep over you haven't answered the phone that's a yes love you bye! Hiro was not looking forward to the riot act they'd be getting.

At least Fred was amenable to being thrown under the bus.

Indeed, Hiro could tell that in the middle of the whole I can't BELIEVE you why didn't you call earlier would it have KILLED you to stick your head in and tell me that she was happy he had gotten out of the house, that he was interacting with people, seemed calmer after giving them some breakfast and okay with him asking if they could take it in the garage since the café was so busy.

And once they were in the garage with their moments of silence observed, they could get started on the important stuff.

"Okay," Hiro said, as Baymax put his information on Yokai on a computer screen. "What did we learn last night?"

"That there's someone out there who wants us dead?" Wasabi asked, hand half-raised. "I'm sorry, I'm still kind of stuck on that point."

"And that's a fair point. Anyone else?"

"That he's obviously a supervillain because of the outfit and sinister intentions," Fred put in.

"That he stole Hiro's microbots, which we didn't tell anyone about and which no one knew about until the expo," Gogo said. "Which means he was at the expo."

"Great—so he could be someone we know," Wasabi said.

"I have a theory about that," Fred said, leaning around Wasabi dramatically.

Fred's theory wasn't any clearer once he had distributed his reading material. Nor was it any clearer when he started explaining the various characters featured.

"The point, Fred," Gogo snapped finally.

"The point is, all of these supervillains have the rich-person secret identity—which brings us to the hypothesis my evidence is supporting: Yokai is, in reality—drumroll please thank you Baymax—Alister Krei."

Dead silence followed this declaration.

"Wait, what?" Hiro asked finally.

"Think about it," Fred said, pointing at him. "He offered to buy your microbots, but you turned him down. Except the word no doesn't apply to people like him."

"But why would Krei do this?" Honey Lemon asked. "Why would Krei do any of this?"

"Power, mostly—possibly money, other reasons…I'm sure it'll all get explained to us during the villainous monologue."

Obake nudged Hiro, shook his head.

"I'm not sure about this," Hiro said, putting the comic book on a nearby table—Fred quickly scooped it back into its plastic covering. "But I'm with Fred, I'm sure it'll get explained after we catch the guy."

"Still a little unsure on the how of that," Wasabi pointed out.

Hiro couldn't help the grin. "I have some ideas."

Hiro's ideas mostly involved taking everyone's school projects and turning them into offensive weapons—like how he had turned Professor Callaghan's robot concept to bot-fighting and then rendered it down to microbots. Coming up with an idea from a dry well like he had when brainstorming for the expo left him frustrated, but when he had a preexisting concept to fuss with…well.

The first day was spent brainstorming ideas with everyone, getting the basic concepts of their projects down to mess around with, scanning everybody so he had body types to work with when coming up with the armor—Fred and Heathcliff ran everyone to their various places so they could pick up their projects to work with in the garage.

In the meantime, Baymax 2.0.

"I don't know, I'm still not feeling the spikes," Hiro said, considering the fresh design they had drafted up, this time with more of a concept of evading the microbots instead of trying to power through them—that design had been made with haste, worry that the guy would slip away to never be found fueling the need to do it quick and dirty. Now that they knew Baymax could track him down wherever….

Now they had the luxury of puzzling through everything, to make the perfect robot to trap this guy and make him pay.

Obake rolled his eye, fiddled with a couple of different components on the computer—designing with him felt like an oddly epic game of tennis, where he'd hit over a blistering idea to get it served back at him with more speed, volleying it back and forth and giving it more weight and refinement and just sheer awesomeness—

He was honestly startled when the others came back—he hadn't realized they had been gone that long. It didn't feel like that long.

They went deep into the night discussing the nitty-gritty of their various projects, Aunt Cass finally coming out and saying she had done up the living room for a sleepover because I can't imagine any of you heading home at one-thirty in the morning GUYS SLEEP PATTERNS PLEASE (which Baymax agreed with). And then muted brainstorming in the living room because they were still going too hard to quit. It took hours to actually fall asleep, it felt like.

Aunt Cass had concerns when she brought them breakfast the next morning.

"Please tell me you guys don't always do this," she said as they dragged themselves back to the realm of the living.

"Sleep is for the weak I have a GPA to maintain," Gogo said, feeling around before Heathcliff stopped her wrist and put a mug of coffee in her hand. "Thanks."

"Indeed, Madame Gogo," Heathcliff said, arching an eyebrow when she downed half of it in one swig. "I'll just be fetching the refill then."

"Would you?"

"Eight to ten hours of sleep is the recommended time for most healthy individuals," Baymax put in, carrying a tray of breakfast foods. "A proper night's sleep is important for healthy brain activity."

"We'll work on it," Hiro muttered—blinked when Obake waved at Aunt Cass.

Aunt Cass had put down the tray and picked up her coffee mug, leaned over seeming politely confused—

All the way confused when Obake took her mug and drained it in one go.

Gogo blinked blearily at him before apparently coming to a conclusion.

"Oh it's on."

After breakfast and Gogo and Obake going through a carafe of coffee on their own and the rest of them adjusting to the concept of Heathcliff helping in the café while they worked (which seemed most baffling to Aunt Cass), they got to work on the next step of the grand scheme.

That is, figuring out how to weaponize everyone's projects.

Hiro started with Wasabi, since his lasers already had the obvious potential—listen as Wasabi explained and showed how they worked, figured out how to make them into something transportable that could be turned on and off, machining it up….

"Now I guess the next problem is finding a place to test it," Hiro said.

"No problemo, we can do it at my place," Fred volunteered.

"Great," Hiro said, sticking his head into the house to look into the café—for a Tuesday it was packed. "Except I think Heathcliff's tied up."

"That's okay we can work on my costume!"

Fred was one of the big question marks, since he didn't have a project he was working on at SFIT—sort through some ideas while the 3D printer handled Wasabi's armor, let Fred down easy when he pointed out that none of them were geneticists and none of them had access to radioactive material.

"But I do have an idea," he assured him.

That described their next couple of days—by the end of the first they had something for Wasabi, Gogo, and Honey Lemon to test out, 3D printer working overtime with Obake ironing out the coding.

And then testing everything in Fred's backyard (which was too base a term but what the hey) with Heathcliff playing Yokai so they had a target. He seemed to be taking this all in stride, at least.

Hiro, Obake, and Baymax went back home after three successful tests, ironing out one or two kinks and making some headway on Baymax 2.0. Going with red on his armor—everyone's armor was color-coded so they could keep it straight when they pulled it out of the printer.

Another thing they were working on: Hiro's armor. Because Hiro fully intended to get up close and personal with this guy. Once they got his mask he'd be a sitting duck, and with a big robot backing him, he felt pretty confident about getting in the guy's face and giving him ALL the what-fors.

Obake was great to work with on this—Obake would identify weaknesses, scribble down a different concept, was easy to build off of and killer at coding.

Obake was also resolutely not suggesting anything for his own armor, despite dropping hints that they go test Hiro and Baymax's armor when they were finished.

Obake was definitely in for a surprise.

The first germ of an idea came from poking around on that little purple drive with the weird one-eyed monster decal on it, that was currently plugged into the computer Obake was spending the most time on—that was a mistake, he opened up the wrong file and a virus started eating through the computer before Obake stopped it, fixed it, and glared at Hiro.

"Geez, sorry," Hiro said, leaning away with hands up. "Didn't realize you were keeping Keramon in there."

Confusion flickered through Obake's expression.

"Keramon—from Digimon, there was a movie…nevermind," Hiro said, waving him off. Point at the flash drive. "What is that then?"

Obake scribbled a short note on the notepad: Personal. Dangerous. Do not touch.

"Funnily enough, I got that. What, is it nothing but viruses?"

Obake considered, waffled a hand, went back to work. Hmph.

But he had a very convenient way to get back at him.

So, in between machining up designs with the others and testing them out, he had a different set of armor he was designing and making, disguising it in-between working on the others' outfits—finally finished up Fred's costume, he was going to love it—

Fred did, he totally loved the costume and absolutely refused to take it off—at least Hiro was assured it was going through some rigorous stress-testing. As for the last handful of designs….

Purple had been tempting, would have been too on the nose—

What kind of name was 'Ghost' anyway?

White and black worked, as colors of death and bad luck, he'd appreciate the irony—red as the highlight color, matching the decal on his virus-drive. Use one of their early-draft ideas for Hiro's outfit for the gloves….

But in the meantime: Baymax 2.0 was finally ready for testing.

Hiro was practically bouncing with excitement—they had sent everyone else ahead to Fred's place to keep stress-testing their costumes (Obake's idea)—now it was their turn. Grab his own helmet—

"So?" he asked Obake. "Ready to suit up and wow the others?"

Obake didn't seem convinced.

"What, afraid to test out our cool new tech?" Hiro asked, pulling his helmet on. "Ready, Baymax?"

Baymax looked down at the shiny new armor he had been shoehorned into—bigger, bulkier, more heroic-shaped, sleek and shiny and red, stronger scanner and smoothed-out coding they were absolutely going to destroy Yokai when they found him and there was no escaping them this time they had ROCKET FISTS and BOOSTERS this was going to TOTALLY. ROCK.

"My: prior concerns, still stand," Baymax decided. "I fail to see how: flying, makes me a better healthcare companion."

"And I fail to see how you fail to see how awesome it is!"

"I do not see how that affects my healthcare capabilities."

"Oh brother," Hiro muttered, rolling his eyes and nudging Obake. "Come on, humor me—or do you want to run over there and see everyone's faces when we come in for a landing?"

Now Obake seemed concerned, doubly so when Hiro climbed up on Baymax's back and directed him into the alley—pretty sure they had enough room to test out the rocket thrusters this was SO going to ROCK—

"What?" Hiro had to ask, smug as he leaned on Baymax's shoulder. "No faith in our totally awesome tech?"

Obake grimaced, ran back to get his notepad, scribbled something down as he came back, held it up: Your aunt Cass will HEAR THIS. 'Hear this' double-underlined, wow.

"We will be totally fine! She'll think it's a plane or car or something."

Wouldn't it be better to test remotely? And NOT from your back alley? Where it can be traced BACK to you?

"Testing remotely: would be safer," Baymax agreed.

"You guys worry too much," Hiro said. "Here, I'll show you—Baymax: wings!"

Baymax stood at attention, accessed the pertinent programming—wings shot out. Hiro could already see Fred totally geeking out. "Great! Now, rocket boosters! Let's go!"

Actually got off the ground this was working they were flying the others would be SO STOKED when they came in for a landing—

So maybe there was one hiccup in the programming, considering Baymax's belly-flop—

And then they were rocketing down the alley, out into traffic, down the street—barely had a concept of startling Lonnie so bad his groceries went flying—

"AAAAH UP UP UP UP—" Baymax angled to obey—"No wait too high TOO HIGH—"

Several terrifying moments later, and Baymax was perched on one of the Golden Gate towers, Hiro clinging tight to his back and trying for deep calming breaths.

"Okay," he wheezed finally, dizzy from relief, adrenaline, fear…take your pick. "That was…okay."

Baymax was looking at him. "Your neurolevels are: elevated, and you are showing signs of increased: adrenaline, and serotonin."

Hiro blinked at him. "Meaning?"

Baymax blinked, turned his head. "It means the treatment is working."

"What? Wait nononononoBAYMAAAAAX!" Was totally not ready for Baymax to tip off of the bridge, plummet to the bay—

And then take him on what had to be the most incredible joyride ever.

It was…amazing. It felt like they were actually outrunning that dark fugue that had settled in on Hiro ever since the fire—soaring through the glittering cityscape of San Fransokyo, threading through the tether ropes of the turbines, outpacing an express train, doing loop-de-loops around signs about the city, circling a gleaming glass building—

For a moment, he had a memory of Tadashi that wasn't laced through with pain, of the last time they had to outrun angry bot-fighters and they had caught air on the moped. For a moment, it felt like all that darkness had been left behind in the wake of their booster rockets.

For a moment, at least, he was free.

They finally came in for a landing on one of the fish-kite-patterned turbines, giving Hiro a chance to catch his breath, to process the whole thing….

"That. Was. AWESOME," he said finally, leaning against Baymax and enjoying the view. "I. Am. NEVER taking the bus again. Ever."

Baymax considered him after a few blissful minutes. "Your: mental health, has improved. If you are satisfied with your care—"

"What? No wait no," Hiro said, bouncing up to face Baymax. "We still have to get that guy, remember? Come on, let's see how your scanner works."

Baymax blinked, stood, looked around—

"Scanner capacity at: five-thousand percent," Baymax announced. "Scanning now."

Hiro kept clenching and unclenching his fists—this was going to work, this had to work, please let it work—

"Scan complete," Baymax announced. "The man in the kabuki mask, is over there." Point. Hiro looked—"On that island."

It wasn't big enough to be Alcatraz, and they were at a wrong angle to see Angel Island—

That left the dark little bit of land, big enough to house a forest—

And, just barely catching the light of the setting sun—some sort of compound, that at usual angles would be hidden from view.

Yokai was on Akuma Island.

"Yes!" Hiro cheered, scrambling back onto Baymax's back. "Come on, Baymax—let's go get the others! Obake first, okay?"

Couldn't help looking back as they sped back home—soon, they'd get that guy. Soon, they'd avenge Tadashi.

But first, they needed the rest of the team.

But first, they needed to get the last member ready. And with everyone together….

That guy wouldn't know what hit him.
