The three had done their best to get out of the warehouse to save their eardrums, though when they got outside, the noise was thankfully a lot better. That low audible growling still could be heard from inside the warehouse.

"G-GoGo, are you okay?" Hiro asked, his ears ringing. Baymax was noticing something coming from within the warehouse. It was moving slowly. GoGo nodded, feeling a lot better already now that the noise had been dealt with.

"There appears to be a robot insi-" Baymax was knocked away by the remnants of the door being broken off the hinges. They saw the robot he mentioned. That all too familiar rust colour was revealed along with it. It was about as tall as they were and had a human shape to it. Those long claws on each hand looked very clean unlike the rest of its body, though they could see the robots insides, full of its electronics and circuits.

"Baymax!" Hiro ran over to help the puffy robot up. GoGo grinned, seeing the robot. It was easy to assume where it came from.

"A monster that changes size… a toy with its wires showing and now a 'bot with its wires showing," GoGo could only assume that this robot was the toy they had been holding mere moments ago that could change size somehow. She didn't like the idea of fighting it like this. She had no armour or anything, and her leg seemed quite against the mere thought of the stress. The robot focused on her and ran at her, taking a swing with its claw. GoGo quickly dodged it. She saw the opening, kicking the robots knee in and making it buckle onto its legs. She then bashed it in the head with her elbow.

"Jeez!" GoGo felt like the one getting hurt here. The robot was already getting off the ground. The few blows she dealt to it did nothing but injure herself at most. It growled, those green eyes focusing on her, though the robot couldn't get a chance to attack before a loud clank emitted from the back of its head. Hiro had tried to get the jump on it with a lead pipe he found once he was reassured Baymax was unharmed, though the blow with the pipe did a decent bit of damage, having dented the robots left arm, and made the arm limp and cease function.

"Get off her!" Hiro growled. The robot swung at him with its free arm, slashing that pipe into pieces, only leaving behind a short piece. He and GoGo had to just buy time until their friends could get there. GoGo had an idea though. The robot's limb was damaged and it was focused on Hiro right now. She quickly grabbed its limp arm, angering it. It roared as it slashed away, cutting her arm and making her jerk back, though that was enough to get what she wanted. GoGo held her wound, seeing one of tis metal claws collapse to the ground. She had gotten it to fall off.

Hiro grabbed the metal claw and stabbed at the robot, piercing its chest, leaving the claw embedded within it. The rust covered robot shook violently before it ran away from them. Hiro quickly went over to his girlfriend.

"Did it hurt you?" he panted, feeling like the adrenaline was mainly keeping him energized right now.

"My scans indicate her wound is light and requires minor bandaging," Baymax said while coming back to the two of them, having finally gotten to the two after sending another emergency message to their friends.

"Calm down, Hiro, I barely noticed…" GoGo reassured, though they were all worried about where their robotic enemy had ran off too. They clearly hadn't destroyed it yet, though Hiro had something strike his mind.

"Wait… this thing grows in size, but how does it do that?" he wondered aloud before they heard a crashing noise.

"Perhaps with metal consumption?" Baymax spoke the only thought he had, but he was not the best with machines. Hiro and GoGo could only look to one another at the thought of this.

"Do we let it go and wait for the others?" she questioned. This thing was in the warehouse again, and there were crates filled with scrap metal in them. Hiro shook his head.

"Nah. We can only distract it and buy time," he claimed as they ran back inside. They couldn't see any sight of the robot they had just been fighting. Some of the crates were toppled over now with their contents missing. They heard a scraping noise before seeing another crate from the next floor falling toward them. Baymax caught it easily though, setting it aside.

"Please be careful. Something this heavy landing on you could damage your spinal cord," Baymax warned.

"Th-thanks, Baymax," he sighed in relief, though they couldn't see the robot. They could hear it and the scraping of its claws. After seconds, they finally caught glimpse of the robot, but it had changed. Now the mechanical monster was crawling on all fours, its internal circuits being slightly covered like it had gained a new case of armour.

"It looks quick, that's for sure," GoGo admitted. It was like the robot was circling its prey the same way an animal would. They saw it begin crawling along the wall to the windows in the ceiling to try and climb out. They heard the glass shattering, and they made their way outside, not wanting to lose track of it. They could see the creepy robot crawling along the rooftop. Before it could get far, they saw a blue ball get thrown up there. The ball exploded on contact with the roof, making the surface slippery. The robot couldn't get a grip in time before it slipped off the roof, falling to the ground on its back. It growled in anger, trying to get back up.

"Guys!" they heard an all too familiar voice, seeing Honey Lemon, Wasabi and Fred running to them in their armour.

"Hello," Baymax greeted their friends.

"Thank goodness you guys got here," Hiro was a lot more relieved now. He could rest easy, seeing them here. Wasabi handed over a bulky backpack that he had brought the threes gear in.

"Are you alright?" Honey Lemon asked. GoGo nodded, starting to get a little annoyed by the question being asked so often like she was helpless. She didn't waste any time trying to suit up.

"Yeah, we're fine. Just don't lose sight of that… robot," Hiro's voice trailed off, mentally face palming. The robot, as they could see, had taken the chance to vanish during their minor worry of their friends. All Hiro could do now was suit up and get ready to hunt it down again.

"I'll stay behind to get Baymax ready. You guys need to find it now before it finds anymore of those crates," he insisted. If that robot got anything more to eat from those crates, it would get even harder to deal with. GoGo stretched, feeling good to be back in her yellow armour.

"Alright, let's split up," Fred suggested. The group all agreed, Wasabi going off with GoGo to the right side of the facility, Honey Lemon going with Fred to the left side. This left Hiro and Baymax to investigate their own area, though the teenage boy had to get Baymax ready since his armour was the toughest to get on.

"Kristoph is not going to be happy to hear about this…"
