Hiro and the team watched the video as the flight pod's engines fired up. The portal was humming. A computer-generated voice echoed through the lab: "T-minus thirty seconds to launch."

"All systems go for pod launch," Krei said.

A technician suddenly said, "Sir, we've picked up a slight irregularity in the magnetic containment field." "Huh," Krei said, looking at the readout on the screen.

One of the generals stepped forward. "Mr. Krei, is there a problem?"

"No, no problem," Krei said with a wave of his hand. "It's well within the parameters. Let's move forward," he said to the technician.

"Five, four, three, two ... one," the voice said. "Pod engaged." And the pod shot into the first portal, but the moment it entered, alarms screamed.

"We've lost all contact with the pilot!" a technician yelled. When the second portal exploded, Krei's audience scrambled out of the way.

"Oh, no," Honey said as they all watched the technicians panic. They understood that the pilot now had no way of exiting the portal.

The video was becoming shaky. A spinning vortex was forming at the center of the first portal. It was growing stronger and stronger. Items in the lab began flying into it. Suddenly, the vortex became strong enough to pull the concrete from the walls. The place was going to implode!

"The pilot is gone!" a technician yelled.

"Krei, shut it down! Now!" the general shouted just as Krei hit a kill switch.

The video screen in front of the friends went black.

Hiro stared numbly at the screen. Now he understood why the lab was destroyed. He figured the government must have taken over Krei's equipment after the disaster.

"Krei's using my microbots to steal his machine back. But why?" Hiro asked.

Suddenly, a familiar sound drew everyone's attention to the lab. It was the sound of buzzing microbots—millions of them! Hiro looked out the control room window. The white-and-red face of Yokai came into view. He was standing on a platform of microbots.

They watched the black-cloaked figure raise his arm and the microbots hurled a chunk of debris at the control tower.

The debris smashed into the tower's base. Hiro and his team held on as the tower buckled and swayed. A final wave of microbots leveled the entire structure.

Yokai smiled as he watched tons of rubble thunder to the floor. There was no way anyone could have survived.

Yokai turned his attention back to the business at hand—moving the precious portal. He used the microbots to dismantle the last portions of it.

Meanwhile, under the control tower wreckage, Hiro and his buddies huddled beneath Baymax. His huge carbon-fiber-covered body had protected them from the falling debris. Hiro gave Baymax a nudge. "Get us out of here!"

Yokai was ready to command the bots to raise the portal up through the hole in the lab's ceiling. Then—smash! Baymax's armored fist came crashing through the control room wreckage. Yokai spun around and saw Baymax throwing off steel beams and chunks of cement. He was stunned to see Hiro and the team come out from the wreckage.

Yokai suddenly realized he had to deal with this annoying team of misfits before he could get the portal to safety.

Hiro and the others came at Yokai with everything they had. "Go for the transmitter behind the mask!" Hiro yelled.

But before Baymax could make a move, a wave of microbots knocked him back. Hiro ran to help him, leaving the remaining team face to face with Yokai.

"All right, what's the plan?" Wasabi asked.

Fred leaped over Yokai. "Super-jump!" he yelled. "Gravity crush! Falling hard!" he narrated as Yokai swatted him away with a wave of microbots.

"Seriously, what's the plan?" Wasabi called.

"Go for the mask," Go Go instructed.

"Right behind you!" Honey replied. The two of them took off together.

Go Go rode up a wall and flung her discs at Yokai. But Yokai dodged one while he deflected another. The discs flew past Yokai, just missing Honey as she lobbed a chem-ball. The chem-ball created an ice patch that caused Go Go to slip. She skidded on the ice and slammed into Honey, knocking them both down.

Yokai turned to Wasabi. Wasabi did his best to sound brave. "You want to dance, masked man? 'Cause you'll be dancing with these!" He waved his laser hands. "Hand over the mask, or you'll get a taste of THIS! And a little bit of THAT! Ha-ha!"

Yokai threw a cloud of microbots at Wasabi. When Wasabi slashed at them wildly, the microbots seemed to scatter. Wasabi was thrilled. Then he looked down and saw that the swarm was covering his feet and climbing his legs. They lifted him off the ground and threw him into Fred. Fred unleashed a stream of fire that sprayed like an out-of-control garden hose as Wasabi knocked him to the floor.

Yokai was pleased. Most of the team was now out of commission. He turned his attention back to re-forming the microbot platform and raising the portal out of the roof. The job was almost done when Hiro, riding on Baymax, flew at him full force. Hiro was dismayed to see his friends all knocked out of the fight. They were a team, but they weren't fighting like one.

Yokai angrily sent a stream of microbots at Baymax and knocked him back. The jolt sent Hiro flying forward, slamming him into Yokai. As Hiro and Yokai tumbled down, Yokai's Kabuki mask flew off. All the microbots instantly fell to the ground.

"It's over, Krei!" Hiro said.

Yokai had his back to Hiro. But when he turned, Hiro's eyes grew wide in disbelief.

小宏和其他队员们看着飞行吊舱的引擎启动了。传送门嗡嗡作响。电脑合成的语音在实验室里回荡：“发射倒计时三十秒。”

“所有系统准备发射吊舱，”格利说道。

一位技术人员突然说道：“先生，我们检测到磁力控制场有轻微的紊乱。”“哦，”格利看着屏幕上的读数说道。

有位长官向前一步说道：“格利先生，出问题了吗？”

“不，没有问题，”格利摇着手说道，“这在正常参数范围内，继续吧。”他对技术人员说道。

“五、四、三、二……一，”那个声音说道，“吊舱发射。”吊舱快速进入了第一个传送门，可就在吊舱进入的瞬间，警报响起了。

“我们与飞行员失去联系了！”一位技术人员大喊道。第二个传送门爆炸时，格利的观众们都开始慌乱地逃跑。

当大家都看到技术人员恐慌无措时，哈妮柠檬说道：“哦，不”。大家都明白，那名飞行员现在再也不可能走出传送门了。

视频画面开始晃动。第一扇输送门中间形成了一个旋转的漩涡，而且变得越来越强大。实验室里的东西开始飞向漩涡。突然，漩涡变得更加强劲，把所有混凝土从墙上吸了进去。这个地方马上就要向内聚爆！

“飞行员消失了！”一位技术人员大喊道。

“格利，把它关掉！就现在！”将军喊道，格利按下了开关。

在大家面前的荧光屏暗了下来。

小宏愣愣地看着屏幕。他现在知道这个实验室被毁的原因了。他估计政府在这场灾难之后接管了格利的设备。

“格利在用我的微型机器人偷回他的设备。可这是为什么呢？”小宏问道。

突然间，实验室里一个熟悉的声音引起了每个人的注意。这正是微型机器人发出的嗡嗡声——成百万的微型机器人发出的声音！小宏透过控制室的窗户向外望去，带着红白相间面具的妖怪出现在了大家的视线中。他正站在由微型机器人构成的平台上。

他们看到这个穿着黑色斗篷的家伙抬起他的手臂，然后微型机器人便将一大块残骸掷向了控制塔。

残骸猛砸在了控制塔的底部。控制搭开始摇晃坍塌，小宏和队员们都抓紧了周围的物体以稳住自己。最后一群微型机器人涌来，将整个建筑夷为了平地。

妖怪微笑地看着成吨的碎石轰鸣着砸在地上，没有任何人有生还的可能。

妖怪把注意力转回到正在干的活上——运送那珍贵的传送门。他用微型机器人去拆除传送门的。

与此同时，在控制塔的残骸下，小宏和同伴们在大白身下蜷成一团。大白那由碳纤维外壳包裹的巨大的身体保护了大家不受落下碎片的伤害。小宏轻推了一下大白：“带我们离开这里！”

妖怪已经准备好操纵机器人从实验室房顶的大洞处抬起传送门。突然撞击声传来，大白的装甲拳从控制塔的废墟中弹出，把残骸击得粉碎。妖怪转过身来，看见大白正在扔钢梁和水泥块。看到小宏和队员们从废墟中走了出来，他很吃惊。

妖怪突然意识到，在他安全地把传送门运走之前，他必须处理掉这队讨厌的与他格格不入的超能少年。

小宏和其他队员用他们所有的武器对付着妖怪。“去取面具下的传感器！”小宏喊道。

但在大白开始行动前，一大群微型机器人就猛地把他击退。小宏跑去帮他，剩下的队员则须自己对付那个妖怪。

“好吧，什么计划？”芥末无疆问道。

弗雷德跳向妖怪。“超级跳跃！”他大喊道。“重力碾压！摔得好惨！”在他给自己做解说时，被妖怪用一群机器人猛拍了出去。

“说真的，什么计划？”芥末无疆问道。

神行御姐指挥道：“去取面具。”

“我来帮你！”哈妮柠檬回应道。她们俩冲出去了。

神行御姐滑上了一面墙，朝妖怪扔出飞盘。可是妖怪躲开了一个飞盘又打偏了另一个。飞盘飞过妖怪，差点击中了正要扔出化学球的哈妮柠檬。化学球将一片区域变成了冰面，导致神行御姐打滑了。她在冰面上滑着与哈妮柠檬撞在了一起，两个人都倒在了地上。

妖怪转向了芥末无疆。芥末无疆努力让自己的声音听起来很勇敢：“想要跳舞吗？面具男。因为你马上就要和它们共舞了！”他挥动着自己的激光手。交出你的面具，要不就让你尝尝这招！还有这招！哈哈！”

妖怪朝芥末无疆扔出了大量的微型机器人。芥末无疆疯狂地砍过去，微型机器人看似散落到了地上。芥末无疆很激动。随即他低头一看，看见那群机器人覆盖住了他的双脚，爬上了他的双腿。他们把芥末无疆托起扔向了弗雷德。芥末无疆将弗雷德击倒在地时，弗雷德刚好释放出了一束火焰，因此火焰就像花园里失控的浇水管一样，胡乱喷射起来。

妖怪很高兴。大部分的队员已经失去了战斗力。他将注意力转回到了平台重组，想把传送门抬出屋顶。就在他快完成时，小宏骑着大白全力冲向了他。看见他的朋友们在战斗中被彻底打败，小宏很惊慌。他们是一个团队，可是他们并没有像一个团队那样作战。

妖怪愤怒地朝大白打出一束微型机器人，把他击退了。颠簸之中，小宏向前飞了出去，和妖怪砰地撞在一起。小宏和妖怪跌下来时，妖怪的歌舞伎面具掉了下来，所有的微型机器人瞬间掉在了地上。

“一切都结束了，格利！”小宏说道。

妖怪背对着小宏。可是当他转过来的时候，小宏难以置信地睁大了双眼。
