Based on penumbraphantasm's amazing Ben Cop AU. This might make more sense if you go check out this post (/post/84305916026/i-noticed-songs-like-the-chase-and-the-final) on their Tumblr.

Update: I'm considering writing a 2nd chapter from GCBC's pov y/n

Ben hung back uncertainly as Lord Business towered over GCBC and berated him over letting the Special get away. Sure, GCBC had been the one leading the mission but… was this really necessary? Ben had been there too, and yet since entering the office, Business had barely even spared him a look. He was grateful to escape the overlord's wrath, but it left a knot of uneasiness in his stomach. It was too good to be true. The other shoe was going to drop any minute now. And it hurt to see his partner practically bending over backwards to appease their boss.

The knot tightened when a metallic, evil-looking nozzle descended from the ceiling and slithered towards GCBC. Ben made to move forward, to intervene, but then Business gave him a look so full of vehemence it stopped him in his tracks. He swallowed.

"Sir," Bad Cop said, leaning away from the nozzle as it closed in on him. "I don't know that this is necessary."

"Oh, don't worry," Lord Business said casually. "I won't test it on you." Ben felt a momentary spark of hope, but it was crushed as Business' tone turned ugly. "I'll do it on your parents."

Both Ben and GCBC gaped as suddenly a small cottage with a green yard slid up out of the floor. Standing in front was an elderly couple that Ben recognized from photos that Good Cop fondly shared with him on occasion.

"Mummy, Daddy," Bad Cop said, taking a step forward. "What are you doing here?"

The uncharacteristic vulnerability in Bad Cop's voice sent a twinge of something through Ben's chest, and as Business tried to direct the couple into posing together, his unease grew and grew. He watched with increasing horror as the scene played out before him, as Ma and Pa Cop were Kragled where they stood.

Business leaned over to hiss into Bad Cop's ear. "Does that upset you, Bad Cop? Surely, you feel bad for your parents. And you wanna help them, don't you?"

Bad Cop looked as if he couldn't breathe. He glanced over at Ben, as if looking for some reassurance or rescue, but Ben was unable to provide either. All he could do was stand uselessly by and watch his partner have his life ripped apart in front of him.

"Go ahead," Lord Business was saying. "Finish the job."

Bad Cop steeled himself and saluted. "Of course, sir." But then Good Cop switched in. "No, I don't want to!" Bad Cop shoved him aside. "We have to." They spun in circles, battling each other. "I don't want to! Would you please be quiet? I can't! You must. But they- Shut it! It's not nice. It's your JOB, man!" And then, at last, Good Cop won. "I can't do it," he said, looking up at Lord Business pleadingly. "They're innocent!"

Business rounded on him. "Just as I thought! Your Good Cop side is making you soft, Bad Cop. Robots! Bring me the Fleece-Crested Scepter of Q-Teep and the Po-lish Remover of Na-eel."

The robot guards hurried forward with the requested items, but before they could hand them over, Lord Business held up his hand. "Wait," he said, fixing his gaze on Ben. "Let's give Ben a little spotlight."

Ah, Ben thought distantly as the Scepter was placed in his hand. There's the other shoe.

"Here's the thing, Ben," Business said, strolling over as two robots grabbed GCBC by the arms to hold him in place. "I don't need a cop who can't make up his own mind – or minds, I suppose. I need a cop who has drive and purpose. A cop I can trust to make decisions. A cop like you."

Ben's throat bobbed as Lord Business circled him, towering above him on those stilts.

"What you have to do now," Business continued, "is show me that you really are that cop. So I need you to do me a teensy little favor."

"Sir?" Ben said, trying to keep his voice from shaking. Had Business added a few layers to his boots or had they always been this ominously tall?

"Oh, it's nothing major," Lord Business said flippantly. "All I need you to do… is remove Good Cop from the picture."

Ben felt like his head was spinning. "Sir, I… I'm not sure what you-" He was suddenly very aware of the weight of the Scepter in his hands and the tall bottle of clear fluid the robots had put down beside him. Good Cop was watching him with wide eyes, his breathing shallow and panicked. Ben shook his head. "No. No, I can't. He's my partner. He's my friend. I-"

"Oh, Ben, my dear boy," Business sighed. "I'm afraid you don't have the whole picture here. It wasn't the Master Builders who caused your accident."

Ben heard a sharp intake of breath from Good Cop. "Sir, please, don't!"

Business glanced over at the cop as he struggled against the robots. "You only brought this on yourself," he said, then turned back to Ben. "It was caused by the very men you are now attempting to defend."

Suddenly everything felt very distant. He looked to Good Cop. "Is that… is that true? Did you guys crash me?"

Good Cop couldn't meet his eyes, and that was all the answer he needed.

"But…" Ben croaked. "Why?"

Good Cop looked about to speak, but Business interrupted. "Before you lost your memories, you were my number one. You were the best! They were jealous that you were such a great officer, they couldn't bear the thought of being second best. They tried to get rid of you, but as you can tell, they failed."

"No!" Good Cop shouted. "That's not-"

Business snapped his fingers, and one of the robots holding Good Cop clamped its hand over his mouth. "When you survived, and it turned out you couldn't remember a thing, they came to me and begged me not to tell you the truth. I'm a bleeding heart, Ben. I gave them a second chance, but you… Don't you think some payback is long overdue?"

Ben put a hand to his head. "I… I don't know… it's so hard to believe…"

"Of course, Ben," Business said, oozing sympathy. "There's no need to take just my word for it. Unfortunately for your so-called friend, we caught the whole thing on tape. Computer!"

The monitor on the wall flickered on. "Yes, sir?"

"Pull up surveillance footage gamma-five-oh-five, would you?"

"Right away, sir."

A static image appeared of a spaceship Ben found strangely familiar, and he realized with a jolt that it strongly resembled the tiny models he was constantly making. That was his ship. That was him.

"Play," said Lord Business.

The ship took off across the screen, racing so fast that the stars in the background became long dashes of light. Then another ship came into sight, hot on Ben's tail, and he recognized it as GCBC's vehicle. And it was firing at him. GCBC was trying to shoot him down. They were trying to kill him.

He wanted to look over at where Good Cop was being held, but he couldn't tear his eyes away from the screen as past him desperately tried to evade the cops. Then a laser clipped his wing and he lost control, going into a tailspin. GCBC dove after him as he spiraled wildly downwards, pulling up short just as Ben crashed into the ground. They slowly hovered over the wreckage before touching down next to it. The door opened, and Bad Cop stepped out. He picked his way over to the mess of the cockpit and pulled out a figure in a blue space suit. The yellow-tinted visor was smashed, and though Ben couldn't see the details at this distance, he knew that some of the shattered pieces had cut into his face. Dazedly, he reached up to touch his own intact visor.

Onscreen, Bad Cop dragged past-Ben clear of the wreckage and dumped him unceremoniously on the ground. The cop reached for the holster at his hip, and Ben's breath caught in his throat, but before Bad Cop could draw his gun, more patrol ships dropped into view, surrounding the wreckage.

The video stopped, frozen on that last image.

He stared at the screen in shock, and Lord Business leaned over to place his hand on Ben's shoulder. "I'm sorry I had to show this to you," Business said. "But I think it's high time you learned the truth. Today isn't the first time they've betrayed my trust." Gently, he took the Scepter from Ben's loose grip and dipped one cottony end into the Po-lish Remover. "And after all that's happened," he continued, handing it back to Ben, "you should be the one who delivers justice."

Ben tightened his grip on the Scepter as he stared at the picture before him – Bad Cop looming over Ben's crumpled form, surrounded by a squad of patrol ships. Anger chilled his spine, and he slowly turned to face Good Cop. "Wow," he said with eerie calm. "How about that."

Good Cop was furiously shaking his head, but one of his robot captors still had its hand clamped over his mouth. He struggled to free himself as Ben advanced on him, casually twirling the Scepter.

Ben stopped a few feet away and tapped the dry end of the Scepter on the ground. He contemplated Good Cop for a moment, then let out a harsh bark of laughter. "Dude, all this time… you were jealous? I thought you were just testing me in the beginning, tough love kinda stuff, you know? But really you were trying to trip me up this whole time!"

Somehow, Good Cop managed to wrench his head free and pleaded, "Ben, it's not what you think!"

"Not what I think?" Ben said, going perfectly still. "I don't need to think anything, man, 'cause it sure looks like you were trying to kill me."

Good Cop wasn't able to say anything to that, and Bad Cop spun in. "You don't have to do this," he said.

Ben felt cold. "Oh," he said, leveling the Scepter at him, "but I want to."

The robots spun Good Cop back in and held him there. "Ben-" he gasped, but it was too late. Ben rubbed the tip of the Scepter over Good Cop's face, smearing and finally erasing it. Once he was done, he stepped back and dropped the Scepter. The robots released Bad Cop, who collapsed to the floor. As if through a great distance, Ben heard Ma and Pa Cop call out to their son. His head was buzzing and his anger had drained away, leaving behind something heavy and leaden in the pit of his stomach. Lord Business was continuing his rant, but none of what he was saying sounded like real words to Ben. He just watch Bad Cop as he picked himself up off the floor and took the remote that controlled the nozzle. There was a grimness to his expression that Ben had never seen before, and the weight in his stomach got heavier, became a molten mess of anger and helplessness and other emotions he didn't want to think about right then.

"Sorry," Bad Cop growled at his parents. "But I have a job to do."

Ben squeezed his eyes shut.
