swarm of bots.
Honey threw a chem-ball at Yokai. But it missed, making ice on the floor. Go Go slipped on the ice as she raced toward Yokai and knocked Honey down. Wasabi knocked away the microbots in the air with his laser gloves, but then he realized the bots were holding his legs in place. The team kept getting in one anotherâs way and was no closer to stopping Yokai. They needed to work together.
Finally, Baymax and Hiro flew close to Yokai. Baymax was pushed back by the microbots, but Hiro jumped forward and knocked Yokaiâs mask off.
âItâs over, Krei!â Hiro shouted to the back of Yokaiâs head.
Yokai turned.
Yokai was not Krei. It was Professor Callaghan!
Hiro was stunned. âBut...but the explosion. You died.â
âNo,â Callaghan replied. âYour microbots kept me safe.â
âButâTadashi...you just let him die?â Hiroâs voice got louder. âHe went in there to save you!â
âThat was his mistake!â Callaghan yelled back.
Hiro was overcome with anger. He stared at the professor. Then he turned to Baymax. âDestroy him.â
Baymax couldnât do it. âHiro, this is not whatââ
Hiro opened Baymaxâs panel. He pulled out Tadashiâs green computer chip, removing the programming that directed him to help people. âDo it, Baymax. Destroy him,â Hiro ordered.
Baymax lifted his rocket-blasting fist and attacked Callaghan.
âGet the nurse chip back into Baymax, now!â Go Go shouted to the others.
Hiroâs friends loved him. And they missed Tadashi. But they could not let him destroy Professor Callaghan. They had to stop Baymax! Fred, Wasabi, Honey, and Go Go kept trying to grab the robot, but Baymax pushed them away. Honey was finally able to jam the green chip back inside him.
Baymax stopped fighting, and Callaghan moved quickly. He put on his mask. The microbots pushed Callaghan and the last piece of the portal out a hole in the roof!
Hiro was angry with his friends. âHow could you do that? I had him!â
âHey, what you just didâwe never signed up for that,â Wasabi told him.
Hiro couldnât believe that his friends had held him back. The professor was a bad man. âBaymax, find Callaghan.â
âMy enhanced scanner has been damaged,â the robot reported.
âAH!â Hiro yelled. He jumped onto Baymaxâs back. âFly!â he shouted. They flew away, leaving the rest of the team stranded on the island.
At home, Hiro went to his computer. He quickly fixed Baymaxâs super sensor. Baymax watched from his charging station.
âYour blood pressure is elevated,â Baymax reported. âYou appear to be distressed.â
âIâm fine!â Hiro yelled. He stood up and touched the panel on Baymaxâs chest. The panel didnât open!
âWhaâ?â Hiro was confused. He wanted to remove Baymaxâs green computer chip.
âWill terminating Callaghan improve your emotional state?â Baymax asked.
âYes! No....I donât know.â
Baymax refused to open his panel. âIs this what Tadashi would have wanted?â
âIt doesnât matter,â Hiro said. âTadashi is gone.â
âTadashi is here,â Baymax stated.
âNo! Heâs not here,â Hiro said.
âTadashi is here,â Baymax said.
Suddenly, Hiro heard Tadashiâs voice. Baymax was playing a video of Tadashi that was stored in his memory.
âThis is Tadashi Hamada, and this is the first test of my robotics project.â
But the test was a mess. Different clips showed Tadashi trying over and over.
Until finally Tadashi said, âOkay. Eighty-fourth test. What do you say, big guy?â
Tadashi reached forward and pressed a button. His face lit up with joy. âIt works! HE WORKS! AH! Ah, yes! This is amazing!â Tadashi spun in his chair. He pumped his fist in the air. âWait
