I should mention that when I first started this, I hadn't seen moonvasion yet, so this is basically how I wrote for Darkwing Duck and Gizmoduck to meet. I changed it slightly to make it work.

It was a starry night in Duckburg, not a single cloud to block the full moon. The docks were almost quiet, not even a cricket daring to break the silence. It didn't stop the Beagle Boys, however, from doing their work.

Big Time walked through the containers on a freighter, seeming to look for a specific one while Burger was operating the crane to sort through them. Bouncer was busy locking up the unconscious guards in charge of the ship's cargo. Big Time sighed, getting tired of looking through a bunch of giant metal boxes, when he saw what he was looking for. It was a standard shipping container, save for the insignia of a bull's skull painted on the side.

"Burger, this one!" he shouted, pointing at the cargo. The crane dropped, grabbing the container, lowering it onto the truck.

"Hey, uh, Big Time?" Bouncer said, joining him after locking up the crew, "This isn't our usual work. Why are we stealing this?"

"Because Ma told us to." He answered, as though that should explain everything. "All I know is someone hired her to pick this up and bring it to them. And they paid well."

"Shouldn't we at least open it to see what it is?" He asked, curious what was in the box. Unbeknownst to the Beagle Boys, there was another intruder on the docks, lurking in the shadows watching their every move. He'd heard that the Beagle Boys had been spotted on the way to the docks and followed them there. Deciding on the best course of action, he waited in the shadows, listening for any more information he could get. Big Time did try to open it, but it seemed to have a high-tech lock to keep them out.

"We should just bring it to Ma so we can get paid." Burger had joined them after dropping the container onto the back of the truck. Their spy had planned to sneak onto the top of the truck as soon as the three were in it, but that plan was thwarted.

"Hold it, evildoers!" a deepened voice called, stopping the criminals in their tracks. Turning back, a metal titan of a duck had landed in front of them. "In the name of justice, abandon that cargo."

"Gizmoduck!" Big Time said with disdain. The figure who had been watching suddenly grew irritated, watching Gizmoduck appear from nowhere and thwarting the criminals that he was planning to stop. He jumped down from the higher level he stood on, facing the towering metal-clad superhero.

"No, no, no, no! I was here first!" he shouted to the duck towering above him. Gizmoduck looked to the spy, now revealed to be a duck with a grey fedora and purple attire including a cape.

"Nice hat." He complimented, smiling at the newcomer. Darkwing almost got insulted by the fact that he didn't recognize him from the invasion but decided to let it go, seeing as nobody but Launchpad remembered him being there. "Are you here to assist me?"

"Assist you?" he repeated disgustedly, "Of course not! I am the terror that flaps I the night! I am the winged scourge that pecks at-" Darkwing Duck was interrupted by a blueberry pie, being flung in his face. Too shocked to react, he looked at the Beagle Boys, who hurriedly pointed at Gizmoduck. "What was that for?!"

"Well you said you're not helping me, you called yourself a terror and a scourge, so I assumed you were a villain."

"It's my opening line. I say it to intimidate the bad guys!"

"Oh, of course! Psychological warfare." Gizmoduck replied, slamming a fist into his hand, understanding what he meant. "Maybe I should do that too." While the two were arguing, Big Time looked around and saw a shipping container open nearby. He nudged Bouncer and Burger and pointed to it, making a push gesture. The two nodded, understanding what he wanted. He quietly gave a hand signal, counting down from three. Once it was done, the brothers altogether pushed Gizmoduck and Darkwing Duck into the open container, before closing the doors and locking them in.

"Darn it!" Darkwing shouted, pointing at Gizmoduck, "Now look what you've done!"

"What I've done?" Gizmoduck said incredulously. "You were interfering while I was apprehending those crooks."

"No, you meddlesome masked moron, I was investigating them." He argued. "They're working for someone. I was going to follow them to figure out who and catch that guy! Now they're going to get away while we're locked in here!"

"If it makes you feel any better, that won't a be a problem for you much longer." Bouncer's voice said from outside the crate. "We're going to drop you in the water so you can't bother us no more." This made the ducks panic.

"Quick, blast the doors open, Gizmo!" Darkwing Duck ordered, pointing at the exit.

"I can't!" he argued. "The explosion will still be contained inward and blow you up too!"

"Then fly and lift the box!" he ordered, filling with terror.

"It still won't work. If I flew upward lifting the box, the downward force from my propeller will push down on the crate." He didn't want to mention how the pressure from the force needed to lift both him and the container could still crush Darkwing.

"Can't you do anything?!" Darkwing was losing all reason. He was going to be drowned soon and there's nothing he can do about it. They felt the container be lifted, before suddenly being dropped two feet, making them lose their balance. They could hear the Beagle Boys' voices outside.

"What was that?"

"Where did he go?"

"Bouncer, leave the geeks in the box, we gotta go! Burger, start the truck!" They heard some bumps and crashes outside before hearing an engine start and drive away. The two readied themselves, unsure what to see outside the exit, which they'd heard open. Cautiously, they walked out through the doors and noticed the Beagle Boys were gone. Nobody was out there. They looked around, but there wasn't a single clue to what happened. Regardless, the Beagle Boys were gone, angering both superheroes at the failure.

"You let the Beagle Boys get away!" Gizmoduck accused, pointing at Darkwing Duck, who seemed indignant at the accusation.

"I did what?!" he yelled incredulously. "I was here first! I was handling this case before you showed up." Gizmoduck was about to rebuke that argument but was distracted by a piece of paper falling on Darkwing's hat. Following Gizmoduck's eyes, Darkwing Duck looked up and caught the falling paper, realizing it was a note.

"You two are terrible at this. Get better, learn to work together, because next time, I won't be around to save you." He read aloud. "What the heck is that supposed to mean?" They looked up to find the writer of the note but whoever dropped it seemed to have vanished. Gizmoduck couldn't even pick up a heat signature. They were gone. Vanished like a phantom.

I want to make this a bigger story, but I need some feedback here and there. Don't forget to comment.
