Hiro and the group gathered up the projects they had made at SFIT and brought them to Hiro's garage.

"We're never going to catch this guy unless we can take out the microbots. So we need to level the playing field," Hiro said.

He looked at Go Go's bike, Wasabi's laser, Honey's chemical concoctions, and Fred's Kaiju costume. "Yep," Hiro said. "We can work with this."

Hiro had them all stand in front of the garage door. "Arms up," he directed before running a scanner over them. "The neural transmitter mustbe in his mask. We get the mask and he can't control the bots. Game over."

Hiro rolled his chair to his computer workstation. Baymax watched over him as he worked late into the night. Hiro had six screens going in order to modify and design all the new gear. The 3-D printer was working overtime printing out sleek armor for everyone. Each member of the team worked hard, dismantling and redesigning their tech. Hiro worked with everyone on the improvements.

When they were done, Hiro and his friend stook their tech out to Fred's estate, where they could refine their new skills. Within the walls of the private garden, Fred set the mood by placing a Kabuki mask on Heathcliff.

Then they all suited up. They looked like they belonged in Fred's collection of superhero action figures.

Honey was thrilled with her new pink body armor. She thought it complemented her blue eyes. Then she looked at her shiny new chem purse. "Oh, I love it! I love it! I love it!" she said. Suddenly, a pink chem-ball popped out and Honey caught it.

"Give it a try," Hiro said, so she tossed it at Heathcliff. The butler was instantly covered in sticky pink goo. Honey clapped her hands.

Go Go was wowed by her new gear, too. Her yellow mag-lev wheels were modified into discs to fit her feet instead of her bike. This gave her the hyper-speed she'd always dreamed of as she skated along. There were also yellow discs on her arms, which were powerful weapons that could be thrown to cut through anything in her path.

"Got to say, I like it!" Go Go said.

"Take it slow," Hiro warned.

Go Go pin-wheeled her arms a bit, then found her balance and zoomed around the hedges. She grabbed a garden hose and coiled it around Heathcliff, immobilizing the butler in a flash.

Hiro smiled and put the head of a Kaiju suit on Fred to complete his armor.

"Whoa! This is awesome!" Fred said. He bent his knees and felt himself bounce. Then he took a giant leap, shouting, "Super-jump!"

"And there's one more thing," Hiro said while a flame jetted from Fred's Kaiju jaws.

"I breathe fire!" Fred shouted. He blasted a ring of fire onto the grass around Heathcliff, who seemed to barely notice. Fred was so happy, he nearly cried. "This is the best day of my life," he told Hiro.

In another part of the garden, wearing his green armor, Wasabi was trying to get comfortable with his new gloves. They were equipped with high-powered retractable lasers that could slice through anything.

Wasabi was terrified of them.

He held them away from his body as he approached a decorative marble pillar. He closed his eyes, and with a single swipe, sliced the pillar in two. He opened his eyes and smiled. "Whoa! Laser hands!"

Hiro smiled. "Guys, I'd like to introduce ... Baymax: Mark 2."

The friends stared up at the huge robot in awe.

Hiro had designed Baymax's bright red body armor in a way that amplified his stature and strength. With a purple ribbed midsection that allowed him to bend, he made a powerful impression.

"Ah. He's glorious!" Fred exclaimed.

Then Honey gathered everyone around Baymax for a quick selfie.

Hiro smiled. "Show 'em what you got, buddy."They stared at Baymax, but the big robot didn't seem to understand.

"The fist!" Hiro said to him. "Show them the fist."

Baymax reached out for a fist bump. "Batalata ... "

"No, not that," Hiro said. "You know? The thing ... the other thing."

Baymax held out his arm and his giant red fist shot out like a rocket. It destroyed a huge flower pot, then smashed through the garden wall.

"Whoa!" was all the team could say.

"My hand is gone." Baymax stared at the wisps of smoke where his hand used to be. Just then, the fist returned to Baymax's arm. "It is back," he said.

"Rocket fist makes Freddie so happy!" Fred squealed.

Hiro nodded. "That's only one of his new upgrades. Baymax, wings!" Baymax's fixed carbon-fiber wings deployed.

"No way," Fred said, dropping his jaw."Thrusters," Hiro directed.

"I fail to see how flying makes me a better health-care companion," Baymax said.

"I fail to see how you fail to see that it's awesome." Hiro climbed on Baymax's back. He locked on to Baymax with magnetic knee pads and gloves that were part of his own black-and-purple armor. And his helmet allowed him to communicate with all the members of the team. "Full thrust!"

Baymax and Hiro took off, but Baymax seemed to have trouble rising into the air. They hit the ground, nearly clobbering the team.

As Baymax and Hiro took off again, the group held its breath. This time Baymax was a little steadier.

Hiro realized they all needed time to sharpen their new skills. And he was right. With some practice, Fred was jumping and shooting flames at targets with absolute precision. Out on Fred's tennis court, Wasabi began knocking tennis balls out of the air with ease—and they were perfectly sliced in two. Go Go was throwing her discs with lightning speed and control. Honey had mastered the art of launching the chem-balls so that they always hit their mark.

And eventually, Baymax flew through the air like a pro with Hiro on his back. So Hiro decided it was time to really crank it up. He rocketed Baymax over the city, barrel-rolled and banked sharply left, then right, weaving through a tunnel, over and under neon signs. They flew past a high-rise that reflected their own image back at them. It was incredible. Hiro couldn't help yelling, "Yeah!"

Baymax told him, "Your neurotransmitter levels are rising steadily."

"Which means what?" Hiro asked.

"The treatment is working," Baymax explained. Hiro could feel it, too. For the first time since Tadashi's death, he was happy.

小宏和朋友们把他们在旧金山理工大学做的项目都集结到了小宏的车库中。

“我们不能除掉微型机器人，就别想抓到那家伙。我们需要创造公平竞争的条件。”小宏说道。

他看着神行御姐的自行车、芥末无疆的激光、哈妮柠檬的化学制剂调和物和弗雷德的怪兽装扮。“耶，”小宏说道，“我们就用这些。”

小宏让大家都站在车库门口。在他打开扫描仪对大家进行扫描之前，他指挥大家道：“举起手来”。“神经传感器一定在他的面具里。我们拿到面具，他就不能控制机器人了。游戏结束。”

小宏把椅子转向了他的电脑工作站。他连夜工作到很晚，大白在一旁照顾着他。小宏同时开着六台电脑，用以修改和设计所有新装备。3D打印机加班加点一直运行着给所有人打印着造型优美的盔甲。小组里的每个人都十分努力地工作着，他们不断地拆除并重新设计自己的高科技装备。小宏和其他人一起努力做着改进。

装备一改进完，小宏就和他的朋友们把高科技装备带去了弗雷德的庄园，在那里苦练新技能。在这个高墙林立的私人花园内，弗雷德让希斯克利夫带上歌舞伎的面具来制造气氛。

随后大家都穿好装备。他们看起来就像弗雷德收集的超级英雄人偶一样。

哈妮柠檬为她的粉红色盔甲感到很兴奋，因为她感觉它能衬托自己那双蓝色的眼睛。随后她看了自己闪着光泽的化学手袋。“哦！我爱死它了！我爱死它了！我爱它！”她说道。突然，从化学手袋中弹出一颗粉红色的化学球，哈妮柠檬抓住了它。

“试试吧，”小宏说道。哈妮柠檬将它扔向了希斯克利夫，管家立即被粉红色的黏性物质覆盖了。哈妮柠檬拍起手来。

神行御姐也在为她的新装备喝彩着。她的黄色磁悬浮轮子被改装成了装在脚上的磁盘，而不再是装在自行车上。这使她在滑行的时候具有了她一直梦寐以求的超高速度。她的胳膊上也配备了黄色的飞盘，这是她的有力武器，可以扔出去切割任何阻挡她行进的东西。

“我得承认，我很喜欢它！”神行御姐说道。

“慢点滑，”小宏警告道。

神行御姐划动了几下胳膊，随即她找到了平衡，绕着篱笆飞快地滑行起来。她从花园里拽起一段浇水用的软管，把它缠绕在希斯克利夫身上，瞬间就把管家弄得动弹不得。

小宏笑着把怪兽装备的头套给弗雷德戴上，这样他的盔甲就完整了。

“哇哦！这个太酷了！”弗雷德说道。他屈了屈膝试了一下自己的弹力。随后他用力一跳，喊道：“超级跳跃！”

“还有另一个功能，”小宏说道，与此同时一道火焰从弗雷德的怪兽嘴巴里喷了出来。

“我会喷火啦！”弗雷德喊道。他喷着火围着希斯克利夫在草地上画了一个圈，希斯克利夫镇定自若像没看见一样。弗雷德十分开心，差点喜极而泣。“今天是我一生中最开心的日子！”他告诉小宏。

在花园的另一边，穿着绿色盔甲的芥末无疆，正在试图收放自如地使用他的新手套。他的新手套配备了高性能可伸缩的激光，能够切开任何东西。

芥末无疆有些害怕这双手套。

在靠近一处装饰用的大理石柱子时，他让戴着手套的双手远离自己的身体。他闭上双眼，轻轻一划，就把柱子切成了两段。他睁开眼睛笑道：“哇哦！激光手！”

小宏笑道：“伙计们，请允许我向大家介绍……大白2.0。”

朋友们抬头敬畏地看着这个巨大的机器人。

小宏为大白设计了鲜红色的盔甲，这样可以放大大白的身高和力量感。盔甲腹部被设计成了紫色的肋骨形状，可以使大白任意弯曲，让大家觉得他十分强大。

“啊，他太棒了！”弗雷德大声叫道。

哈妮柠檬让大家都聚集在大白身边拍了张自拍照。

小宏笑道：“让他们看看你的本事，伙计。”他们盯着大白，但这个大个头机器人似乎没有明白过来。

“拳头！”小宏对他说，“给他们看看你的拳头。”

大白伸出胳膊作碰拳状：“吧嗒啦嗒啦……”

“不对，不是这个，”小宏说道，“你知道的？那招……另一招。”

大白伸出他的手臂，他那巨大的红色拳头像火箭一样飞了出去,打碎了一个巨大的花盆，又打穿了院墙飞出去了。

“哇哦！”所有人除了惊叹一句话都说不出。

“我的拳头飞出去了。”大白盯着他拳头飞出去后留下的几缕烟说道。就在这时，拳头又回到大白的手臂上。“它又回来了。”大白说道。

“火箭拳让弗雷德开心死了！”弗雷德尖叫起来。

小宏点点头道：“这只是升级组件中的一个。大白，展翅！”安装在大白身上的碳纤维翅膀展开了。

“不是吧，”弗雷德张口结舌。“推动器！”小宏命令道。

“我不懂飞翔对我成为更好的健康顾问有什么帮助，”大白说道。

“我也不懂你为什么看不出这有多么帅。”小宏爬上大白的背，通过磁力护膝和与他自身黑紫相间的盔甲配备的手套固定在了大白身上。他的头盔可以让他与战队的每位成员沟通。“全速前进！”

大白和小宏起飞了，可大白在升空的过程中似乎是遇到了问题。他们撞向地面，差点击倒其他队员。

大白和小宏再次起飞时，整队人都凝神屏息。这次大白看似比刚才稳多了。

小宏意识到他们都需要些时间去磨炼他们的新技能。他是对的：经过一些练习，弗雷德跳起来对着目标喷火的技能已经达到十分精准的程度。在弗雷德的网球场里，芥末无疆击打飞来的网球也开始变得轻而易举——网球都被精准地一切为二了。神行御姐抛掷起飞盘来，速度如闪电，收放自如。哈妮柠檬掌握了发射化学球的技巧，化学球总是能够击中目标。

最终，大白也可以像行家一样背着小宏飞翔。小宏决定是时候开始反击了。他骑着大白在整个城市上空飞驰，时而横空翻滚，时而向左大幅倾斜，再向右大幅倾斜，在隧道内穿梭，在霓虹灯上下飞舞。他们飞过一幢高层大楼，里面映照着他们的身影，太难以置信了。小宏控制不住大喊起来：“耶！”

大白告诉他，“你的神经递质水平正在稳步上升。”

“那说明什么？”小宏问道。

“治疗起作用了，”大白解释道。小宏也能感觉得到。从泰迪去世至今，这是他第一次感觉这么开心。
