"Is everyone alright?" Hiro asked everyone wondering is they were fine.

"Yeah, where good." Wasabi said coughing up some dust.

"Same." Go Go replied slowly getting up.

"Wait. Where's, Sebastian?" Fred asked everyone wondering where he was.

They all looked around but couldn't find him anywhere. They became concerned about their friend.

"Guys! I need help over here!" They heard his voice that sounded like he is under something about three feet away from them.

They ran over to where Sebastian was and they start to dig him out of the debris. They kept on digging then they saw Sebastian.

"Thanks everyone." Sebastian tells everyone and Go Go offers him his hand which he accepts and she pulls him out.

"Don't mention it." Hiro said then he turns back to Baymax who is still holding the large concrete on his back.

"Baymax, get us out of here!" Hiro replies and Baymax used his rocket fist to break through the concrete.

The man looks back at them as everyone looks at him in a fighting stance.

"Go for the Transmitter behind his mask." Hiro ordered but the guy got tired of them so he threw the microbots at them.

Everyone dodges out of the way but Baymax was sent backwards falling to the ground.

"Baymax!" Hiro yelled running over to check on him.

Sebastian took out his bow grabbing a arrow as he shoots for the mask but it bounces off of it.

"Great." He said shaking his head and he realized that this is going to be a long day.

"Alright. What's the plan?" Wasabi asked everyone and Fred got in front of them.

"It's Fred time." He said smiling at the mask man then putting on his mask.

"Fred no don't..." Sebastian was about to say but Fred didn't listen.

"Super jump." Fred jumped into the air towards the guy.

"Gravity crush!" He said but the microbots smacked him to the left causing him to fall.

"Falling hard!"

"Great one down already." Sebastian sighed to himself.

"Seriously what's the plan?!" Wasabi asked the three wondering if they had one.

"Get the mask." Go Go said as she runs ahead after the guy.

"Right behind you!" Honey Lemon replies following Go Go with a chem ball in hand.

"FOR REAL WHAT IS THE PLAN?!" Wasabi yelled to them.

Go Go starts skating up the broken metal part and she flips to the other one avoiding the microbots and she throws one of her disc hitting him in the face where the mask is.

The guy holds his mask in place then tries to strike her with the microbots but missed completely and Go Go threw one of her disc again but it missed the guy.

Honey Lemon used the chem ball she has in her hand to jump down as Go Go is fighting with the man and dodging. She makes another chem ball and she waits for the right time to throw it.

Go Go dodges all the guys strike by going underneath gaps, jumping over him, and circling around him. She skates up the wall throwing her disc again but the guy side steps heading towards where Honey Lemon is.

"Hey. Ugh!" Honey Lemon said as she was going to hit the guy with the chem ball, but Go Go's disc hits her in the head causing the chem ball to go flying over to Go Go and lands on the ground.

The chem ball made the floor into a blue slime and Go Go lost her balance from her disc and she fell to the ground sliding over the Honey Lemon tripping her while she was sliding.

"Go Go, Honey Lemon!" Sebastian yelled to them and suddenly Wasabi jumps down ready to fight the mask man.

"Hey!" The mask man turns around towards the sound to see Wasabi standing there with his plasma blades unsheathe.

"You uh, um you want to dance mask man huh? Cause you would be dancing with these. Hand over the mask our you will get a taste of this, and a little bit of that!" Wasabi said to the swinging his blades to show that he means it.

Mask man summoned microbots at him and Wasabi slashed quite a few of them. Sebastian was quite impressed but he knew that Wasabi isn't going to last long.

"Hey! I did alright. Is that all you got?!" He asked the masked man then he realized the microbots are wrapped around his foot.

"Oh, you got that too?"

The mask man controlled the microbots causing them to thro Wasabi towards the girls. But suddenly Fred popped out of no where ready to fight again.

"It's back into the fir.." Fred was going to say but Wasabi hits him and the two slid over to the girls knocking them over.

The mask man summoned a fist microbots but out of no where something hits him in the face causing him to clinch it.

"Hey! You leave my friends alone. You still have one more person to fight." Sebastian said to him unsheathing his sword on his back walking in front of his friends.

Mask man summoned couple of microbot spears as they went flying over to Sebastian. He waits until it got closer before he spins his body around destroying the spears with his sword in one hit.

This shocked the mask man for a second cause he never seen someone who wasn't afraid of fighting him and knows how to fight.

"Sloppy." Sebastian smirks before running towards the guy while slashing and slicing the microbots on his way over.

One spear came to his right as he grabs it breaking it in two with his hand. When Sebastian got closer to the guy he jumps up a broken beam over to the guy and kicking him off the tower of microbots into a wall.

Sebastian walks up towards him and the guy was about to control the microbots with a hand jester but he steps on his hand kneeing the guy into the chest then spin kicked him to the middle of the room. The guy used more microbots spears but Sebastian was faster slicing them and twirling around with his sword.

Suddenly a large fist of microbots came racing above him. Sebastian put his sword above him as he blocks the microbots with it. After blocking it, he tried to push it away from him but it was kinda pushing him down to the floor cause of the pressure.

Sebastian got down on one cause it was getting heavy but he wasn't going to give up so he lift himself back up a bit. Then, out of no where Hiro and Baymax flew around the mask man.

He tried to hit them with microbots but they dodged them with ease and was heading towards the guy. But the mask man punched Baymax into the ceiling causing Hiro to fly off and collided with the guy and they went flying down stairs rolling when they hit the ground causing the man's mask to fall to the ground.

Sebastian felt the microbots weekend as they fell to the floor. Sebastian sighs in relief and he collapse onto his knees from exhaustion.

"Sebastian, you okay?" Go Go asked him putting her hand on his shoulder.

"Yeah, just a bit exhausted. I'm good though." Sebastian told her nodding and he stands up and the two ran over to the rails with the others and they saw Hiro holding the mask in his hand.

"It's over, Krei." Hiro told the mask man which he gets up turning around towards him and was surprised to see who it was.

"Pro, Professor Callaghan?" Hiro asked surprised.

Everyone but Sebastian gasp in shock to see that their professor was alive and the bad guy. Sebastian jumps over the rails walking over to Hiro.

"But the explosion. You died." Hiro said to him a bit surprise.

"No. I had your microbots." Callaghan explained with stern look.

"But, Tadashi you just let him die." Hiro said to him.

"Give me the mask Hiro!" Callaghan replied not in a mood to talk.

"He went in there to save you. You almost killed, Sebastian too!" Hiro explains to him a bit sad and angry.

"That was their mistake!" Callaghan clarifies to Hiro and Hiro was in shock causing him to snap.

Baymax lands behind Hiro who was looking at Callaghan with angry expression and he said to Baymax "Baymax destroy."

"Hiro, no. Think about what you are doing." Sebastian explained to Hiro who shook his head still looking at Callaghan

"My programming prevents me from injuring a human being." Baymax told Hiro looking down at him.

"Not anymore." Hiro replied pushing the button on Baymax taking out his healthcare chip to his right.

"Hiro, this is not what.." Baymax is about to say but Hiro jams the button into Baymax with the fighting chip.

Baymax eyes turned red as he looks at Professor Callaghan who was backing up slowly in fear of the robot.

"Hiro, stop this!" Sebastian yelled to Hiro to make him stop what he was doing.

"No. Do it Baymax destroy him!" Hiro ordered Baymax to try and kill Callaghan.

Sebastian watched as he saw Baymax pointing his rocket fist at Callaghan and was going to launch the fist at him.

"No!" Sebastian yelled sprinting over to Callaghan grabbing him and pushing him out of the way of evil Baymax's attack and they fell to the ground.

"Get out of here, now!" Sebastian said to Callaghan narrowing his eyes at him. Callaghan nods before running off but Baymax launches another rocket fist at him but missed as Go Go came skating down the stairs hitting his arm.

"No! Stop, Baymax!" Go Go replied trying to stop Baymax but couldn't and he hits her to the side hitting a wall.

Baymax starts following Callaghan into a small area and Callaghan trips over a pipe line as Baymax walks over to him. Callaghan starts to back up but Baymax was closer and was going to use another rocket fist, until Fred jumps on Baymax's back trying to get him away from Callaghan.

Baymax tried to get Fred of him by backing up into the wall, but Fred still hold on.

"No stop he's getting away!" Hiro said to Fred as Baymax tosses Fred at Hiro hitting him making him lose his grip onto the mask dropping it.

Callaghan picked up his mask putting it on and he had control of his microbots again and used them to get him up a level to escape.

Sebastian looks around to see Baymax healthcare chip next to Honey Lemon.

"Honey Lemon!" He yelled as she looks at him wondering what he wanted.

"The chip!"

Honey Lemon looked to where he was pointing to see Baymax's chip about three feet away. She grabs it before running over to Baymax who was getting hold down by everyone.

But Baymax tossed Go Go over to Sebastian knocking him down to the floor. Wasabi and Fred got tossed too and Baymax was going to use another rocket fist, but Honey Lemon put his health care chip in causing Baymax to come back to normal.
