Tadashi heads out of the lab to investigate the noise, sees the panic, and immediately runs back inside, dodging his labmates. 

"Baymax! I need you!"

Baymax inflates, and carefully steps out of his charge station. "Tadashi. Are you in need of medical attention?"

"Not me, bud, but plenty of other people. We gotta go, now!" Tadashi grabs his robot by his hand.

Baymax toddles as quick as he can behind his maker.

When they arrive there they will find what appears to be a stand-off between the police and a masked man controlling three industrial robots. Two trucks are turned on the side, blocking the street. The robots are trying to hall off their cargo, a pair of ring-shaped machinery that's currently sparking like crazy.

A lot of people are hiding under cover, many are obviously hurt.

"Baymax! There!" Tadashi directs his robot to one group of injured people. 

He himself runs closer to a different group, ignoring police officers calling out to him.

"On a scale of 1-10, how would you rate your pain?" Baymax asks the first injured person.

Tadashi reaches the first group of hiding people. "Come with me! I can help!"

"What?!" The victim blinks at them "A bullet clipped my wrist!"

The victims lift an arm. It's not a serious injury, but it's bleeding a lot.

"Come with me, I can help!"

He directs them towards Baymax, through a safe route avoiding the fight itself.

Most victims will just obey his commands, happy to have someone guiding them through the stressful situation. Most injuries are not that bad. But this still is a confrontation between people with guns and robots.

At least most people can move.

Most is not all.

For example, one of truck's driver is over there clearly unconscious and under the weight of his vehicle.

"Baymax! I need you!" Tadashi dodges fleeing people to get to the truck.

Baymax follows Tadashi, and upon happening on the trapped man, scans him. "Multiple fractures. Abrasions. And a truck is lying on him."

"Yeah, no kidding! Help me lift it!" Tadashi is struggling to pull the man out without injuring him further.

Baymax lifts the truck.

"Nice one, bud!" Tadashi pulls the unconcious man out, and lays him carefully. "All right, get to work, Baymax."

Baymax gets to work as commanded.

One of the giant robots reaches for the two of them. But the ring thing is disturbed and the robot needs to catch it before it hits the ground. Baymax can do his work and stabilize the man, but now they are between a rock in a hard place with the robots blocking their path.

They can't see what causes it, but Tadashi should be able to catch the moment when an electric cable breaks from a pole and makes contact with the robot.

The machine starts whirring and glowing brightly.

Tadashi looks up in shock, his mind whirring with possibilties when the machine starts glowing.

"What the- Baymax! We need to get out of here."

"This patient is not stable enough to move. Please wait."

"Bud, we gotta go now!"

Tadashi starts looking for a way around the robots, but can't find one. The safest path seems to be towards the glowing thing.

There really isn't any option, specially if he doesn't want to be under a rain of glass and scrap metal as a robot picks up a car.

Oh, it's a delivery truck. The robot is shoving it under the glowing thing to give it support. Tadashi gets to see the logo "Isekai delivery" before being pushed alongside Baymax into an impossible space...

If Tadashi had found this place within a lab, he would be amazed. 

Instead, he screams in terror.

“Tadashi!” Baymax calls, reaching for him.

They both spiral out of control through the weird space. They even manage to hold onto each other for a time... but whatever forces rule this place pull them out right before a bright light engulfs them.

When the light fades, Tadashi finds himself falling from the sky towards the tree covered ground...

...until a woman, with pale skin, slitted eyes and white-brown feathered wings catches him.
