Interdimensional: Continuing the Fight

Disclaimer: I don't own Phineas and Ferb.

A/N: format is the same as the previous two: each chapter begins by indicating the POV it's told from. There's one chapter where I change POV twice in the middle, but it's for the sake of the plot.

Chapter One

PLATYBORG

I shadowed Rodney, trailing as far behind as the range of my radar, tracking, and detection systems would allow. He walked into a hardware store and acted as if he knew exactly where he was going. He browsed the aisle as if looking intently for something and expecting it to be where he last found it. Apparently, he wasn't finding it, because his manner shifted from 'I know what I'm doing' to 'oh, my God, what do I do?'. He roamed the aisles frantically for about fifteen minutes before finally relaxing. He picked something off the shelf and walked to the cash register to, rather unexpectedly to me, pay for the item.

I followed him out of the hardware store and back to his apartment, where he picked up a parachute, slipped it on, and stepped through the portal, pulling the cord almost instantly. I followed, deploying my wings so that I could hover to the ground at a reasonable pace.

Rodney walked down the road, turned a corner, and continued walking...to the storage facility I had visited earlier. I was getting antsy, and I could tell that Perry felt this way when he needed to do something, as he had been the past couple of days. I walked into the storage unit, hugging the wall and watching Rodney closely, whatever it took from my observational arsenal. He hopped into the hole, and I knew what he was after.

I switched to normal vision and flew out of the storage unit. I knew one thing for sure: I had to get to Perry before the Normbots did.

The robots rushed by overhead, and I fired the afterburners, struggling to reach Maple Street. Once I reached my destination, however, I knew something was wrong. Normbots had already beaten me and were fighting not only Resistance members but Perry, fresh from the veterinary facility. He still had it, that was for sure, but I was still tempted to drop by and demand to know what I'd told him about dangerous solo missions, especially in his condition.

Before I could make good on my mental threat, I was forced to pull up and hover, watching as a black-clad man I could've sworn I recognized fought his way through the web of Normbots. At one point, a laser went off, toward the portal. Perry launched himself through the portal, over a platypus-themed catapult, and onto the kids, just in time for the laser to nick the catapult and disappear into the First Dimension.

The man landed in front of the portal, and I drifted so that I could get a good look at his face.

Suddenly I wasn't in the air anymore, or even eighty-percent metal. I was a platypup in my new lair, issued by O.W.C.A., wearing the official fedora for the first time. "Welcome to the agency," a younger Major Monogram said.

"Congratulations, Agent P.," the kid with the curly hair said, swinging his fist through the air enthusiastically.

I snapped back into reality with one word on my mind. The kid's name. Carl. He was a volunteer at O.W.C.A.

"Present your papers or be destroyed."

I turned at the command. A Normbot was hovering almost on top of me, dangerously close. I shot up and back, but the Normbot followed closely. I swapped my hand out for a blaster and fired, hitting him directly in the chest. He exploded instantly, and I returned my attention to the situation on the ground on Maple Street.

"Look who decided to help us out," Carl said bitingly, folding his arms across his chest. I mimicked his gesture and let out an equally biting chatter.

"We're on the same side, here," Candace snapped. "We can't afford to have infighting right now."

"We're only on the same side when it's convenient for him," Carl hissed.

I dropped to the pavement and stepped through the portal without a look at Carl, or the others. Perry was on top of his Phineas and Ferb, and Isabella was off to the side, looking on in awe and confusion, not that I could blame her. I turned to Perry and said, "We need to talk, now."
