Perry and a black-haired and green-eyed Ferb landed at Doofenshmirtz's headquarters. Ferb instantly recognized the place. They'd been by it so many times and marvelled at its odd architecture. This was also the place where they'd come when they accidentally stumbled upon Perry's secret lair. Perry pointed at his throat and Ferb activated the translator.

"Ok, we're going to smash through this door. Now, be careful. He normally has some sort of trap waiting for me the second I burst in. The trigger could be just about anything, so be on your toes." Perry whispered. Ferb nodded and followed the more experienced agent's lead. The door was kicked down and the two swooped in, poised for battle.

"Ah, Perry the—wait, who's this?"

"Heinz, meet my new partner, Agent H."

"Agent H?! Wait...you can talk now? How long has THIS been going on?"

"It's a long story." Perry rolled his eyes. "You wanna go ahead and just go into your maniac rant now or..."

"Oh, oh yeah of course, it's just...man, so much is throwing me off today. Um, I only have a trap for you so..."

"Ah, it's fine. Let's just get this over with."

Ferb watched as the two interacted, not so much like enemies, but like old friends with a minor annoyance between them. Buford and Baljeet got along worse than this when they first met and they wound up being best friends. Suddenly, the man Perry called Heinz was pushing a button and Perry was trapped in what looked like beam of green energy. Ferb hopped into fighting pose, when Perry put a hand up.

"Just wait a second." he whispered.

"Now, Perry the Platypus and...I'm sorry what was your name again?"

"Agent H." Ferb quizzically responded.

"Nah, too hard to remember. I know! I'll call you Hector! Hector the Human."

Ferb turned to Perry and gave a look that said "is this guy for real?"

Perry just shrugged and rolled his eyes.

"Now behold, Perry and Hector. My latest invention. The Stop-Go-Inator!" He paused for dramatic effect and waited for the pedestal the remote sat on rose from the floor. "You see, it all started just last week. I was on my way to visit my daughter Vanessa at work down at City Hall. On the way there, every traffic light I encountered turned red the second I got to it. It was infuriating! So I've invented a machine that will automatically change all red lights to green with the push of this button. With this I can control traffic and take over the TRI-STATE-AREA!" he cackled maniacally.

"That will cause accidents and deaths all over town!" Ferb yelled. He then ran over and was about to make a grab for the device when a gigantic robotic man reached out and stopped him. "Hi! How are you! Nice to meet you. I'm Norm Doofenshmirtz!"

"No you're not Norm!" the man in the pharmacist lab coat yelled. "Sorry, Agent H, it seems as though you're just too new to this to be able to stop me." Ferb wriggled one arm free and aimed it at where Perry was. He launched a silver disc from his wrist and it passed through the beam Perry was caught in, momentarily stopping it and allowing Perry to escape. Perry then tossed his hat and it sliced through Norm's arm, freeing Ferb.

"Ow." The robot monotonically called out.

The two then went on the offensive. Ferb launched into acrobatics and flipped towards the machine while Perry held off the demented doctor. Ferb reached the device and smashed it.

"So what? You destroyed my machine! I'll just make another from the plans saved on that computer." Immediately realizing his mistake, Heinz slapped his forehead as Ferb ran towards the computer and hacked the mainframe. He not only deleted any and all blueprints in a folder conveniently labeled "Schemes", but he also injected a software virus that disabled the computer entirely. As the giant screen slowly whirred and shut down. The Doctor let out an impassioned yell as the two quickly made their escape. "CURSE YOU PERRY THE PLATYPUS AND YOU TOO, HECTOR THE HUMAN BOY!"

He then turned back to his lab that was wrecked from the fight. "well at least nothing blew up." he sighed as he leaned on a device that had been left by Ferb. It was an exploding stink bomb. His apartment quickly filled with green smoke. "ARRGH!" he yelled.

"Well done, Agent H!" Major Monogram called out via the giant screen. "Your first mission was a success.

"Thank you sir." Ferb said as he returned his hair and eye color to normal and changed out of his suit.

Two glasses of sparkling apple cider rose from the floor. "Here's to many more successful missions!" The Major said raising his own glass along with his assistant, Carl.

They all toasted and celebrated a job well done.
