Paradox

In a simple house in a desert, an old man tucked a revolver into his belt, the one of many he would be using for this dangerous excursion. He didn't want to leave in the dead of night like this but he has no choice, time was of the essence and it was his mess to clean anyway. Or was it his other self's mess to clean up? Bah, time was wonky around the Gungeon anyway. He placed his hat on his head and was about to leave, only to pause as he gazed at a picture frame sitting on a nearby desk.

The photo shows a young boy of the age of ten wearing glasses as he smiled for the photo. The boy wore rather simple clothes, brown khakis, black shoes, and a purple hoodie with a white colored revolver chamber emblazed in the front. His heterochromia eyes, one eye red and the other blue, glittered with amusement as his messy brown hair swept down and covered his forehead.

Tipping his hat in a silent apology, he left a white envelope on the ground before silently slipping out the front door. All was silent in the house, until the ticking of a clock and the sound of a gun rang out, making a young Luke Chambers rolled in his sleep.

Six Years Later

" Warning! Incoming debris!"

"Woah!" Luke shouted as the young man of 5'4 tumbled to the floor of the spaceship. The young man clothes haven't changed a bit, except for the additions of black combat boots and similar black fingerless gloves.

The pilot only grinned toothily as he swerved harshly on the steering wheel, "Don'tcha worry Mister Chambers! I used to race through asteroid fields at light speed when I was a wee lad! This is nothing!"

The young man only groaned as he got back on his seat, "Really, no wonder your driving is-OH SHIT! ON YOUR RIGHT!"

The pilot swerved once more as a wreckage of another spaceship rocketed past them, barely clipping the wings. After a few more close calls, their destination loomed in front of them. Planet Gunymede, the home of the Gungeon, and the last place where his father was last heard of. Pushing up his glasses, Luke Chambers quirked a curious eyebrow as he gazed at the surface of the planet as they slowly touched down.

Leaping off the ship, he tossed a bundle of cash to the pilot, "Thanks for the lift Captain Morgan,"

"No problem!" he replied back, "Anything for the son of The Gunslinger!"

Luke nodded once more in appreciation as he turned to leave before noticing something strange, "Hey… isn't that cocaine on your nose?"

The eccentric captain grinned, "Of course! I always sniff cocaine right before I drive!"

"Wait! You've were high the entire time?!" Luke exclaimed as he stared in horror at Captain Morgan.

"Eeyup!" he cheekily replied as he started up the engine, "Good luck finding your father! And don't forget! Always trust in the cocaine!"

With that, the ship lifted itself off the ground and sped off into space. Luke spent a few minutes in mental reflection regarding the fact that he just rode with a pilot that was high out of mind.

'This… is a lot bigger than I thought' Luke mumbled in his head as he gazed upon imposing building that was the Gungeon. As he walked closer, he felt strange. The air in the area felt… distorted. Everything was moving slowly, and then faster, and then back to slow. Luke felt a bit dizzy as the distortion mess his head but he endured as he walked through the entrance of the Gungeon. As soon he walked through, however…

*CRACK!*

"The hell?!" Luke yelled as the Gungeon immediately began crumbling around him. Pieces of stone showered him and glowing multicolor cracks began appearing along the floor and the walls. He began scrambling for cover as even larger pieces of rock began raining. Sprinting for his life, he dove into a large open circled shape doorway.

Meanwhile…

*bang bang bang!*

"DANG GUM NABBIT! What a time to drop my only Blank!" snarled The Gunslinger as he quickly tossed his empty revolver and he swiftly rolled out of the way as a salvo of bullets grazed his poncho. The Lich, both real and glitch versions, only let out a low hiss as they both spun their revolvers, sending wave after wave of red and dark red bullets after their retreating paradoxical counterpart. He quickly retaliated by pulling out another revolver from his belt and began firing back, running along the walls as he slipped past Tombstoners scattered around the floor.

Unfortunately, a stray bullet bounced a wall and hit the Gunslinger in the back in the heel, causing him to trip and fall to the floor. He watched with irritation as both Lichs immediately pointed their guns and opened fire.

*bawoing!*

…Only for nothing to come out of their revolvers. Turning to the right, they spot a Luke staring incredulously at the blue Blank he stepped on, thinking it was a normal bullet.

"…well shit," Luke said with a flat look as The Gunslinger on the other side of the room stared at his son.

The Lichs only renewed their shooting with increased ferocity as Luke joined his father in the shootout.

"You picked a hell of a time to find me Junior!" said The Gunslinger as pulled Luke along as he fired back.

"Choke on black powder you old timer!" snarked Luke as he pulled his own weapon, an oversized Desert Eagle with a hand guard, revolver chamber, and red and black markings. (Think of Emiya (Alter)'s guns from FGO but add the revolver chamber, take away the blades, and shrink it until it can fit into the hand of a teenager).

"Did you have any idea what I went through to find your wrinkly old ass?!" raged Luke as he slid and tripped a Tombstoner before shooting it in the back, "I nearly got eaten by space clothing, FREAKING SPACE CLOTHING!"

The Gunslinger scoffed as he slung yet another revolver at one of the individual Lichs, "Pfft, those Macy rejects? That's nothing! Try fighting moon vampires that are connected to Mother Nature! Then you can complain!"

The Lichs paid no mind to this strange conservation as their sole purpose was to destroy any intruders with extreme prejudice. Such was the eternal servant of Kaliber, he only exists to serve the Goddess. Yet, the one wearing the poncho, he feels familiar, like a long lost brother, or a past-self long forgotten. Who was he?

The Lich was about to go along this train of thought until his glitched counterpart was struck with a rather nasty blow, courtesy of the smoking hand cannon held by a purple-clad teenager as a smirk decorated his face. A smirk that faded away along the glitched Lich as the real one suddenly dropped the book it was holding in order to grab the glitched pistol.

"Oi! That's cheating! We only have one gun each!" complained Luke as he gestured to himself and the Gunslinger.

The Lich proceeds to show how little he cared by spinning both revolvers which launched wave after wave of bullets… that proceeded to bounce off the walls. The attack continued until the room literally became a sea of bullets, with two metaphorical fishes trying their best to stay alive.

"Ain't this a sticky situation eh son!" The Gunslinger remarked as he used a Tombstoner as a makeshift shield.

"More like freaking terrifying!" Luke retorted as he adopted the same tactics as his father.

Both were huddled in a corner in an attempt to escape the onslaught, but bodies of the Tombstoners were rapidly deteriorating. It was only a matter of time before their cover was broken. Luke then tapped the sides of his glasses, activating them into sensor mode. As he scanned the room, he noticed several indents that blended into the wall next to them, perfect size for temporary footholds.

*ding!*

Throwing aside the Tombstoner, Luke recklessly charged forward towards the wall.

"Luke! The hell you're doing?!" yelled The Gunslinger as he watched him get nicked by several bullets.

"Saving our asses old man!" Luke replied with a smirk as he planted his foot on the wall and began running up the wall. He kept running and running as fast as he can until he escaped the field of bullets. As he felt gravity beginning to pull him back down, he leaped off.

As he flew gracefully through the air, he pointed his gun at the Lich's head and fired.

*BANG!*

The Lich stood still as the bullet impacted his forehead.

1 second has passed

2 seconds have passed

3 seconds have passed

4 seconds have passed

5 seconds have passed

*clatter*

Both revolvers fell to the floor as the Lich began to tip backward. The Lich impacted the ground and slowly began dissolving into black particles. Grinning with self-victory, he turned The Gunslinger. The Gunslinger gave him a proud smile before doubling over.

Eyes widening in panic, Luke rushed over, "Dad! What's wrong?!"

Before The Gunslinger could reply, his right hand began to crack, white hairlines appearing on his entire arm.

"Huh? B-but this doesn't make any sense!" The Gunslinger said with shock as his body began cracking even more.

"What the hell are you talking about?!"

"The Lich! He was my future self! If I killed him, the Gungeon wouldn't exist!" The Gunslinger explained as his voice wavered with panic.

"But we did! I shot him in the head!" Luke replied as he pointed the spot where the Lich died.

As soon as the sentence left his mouth, both pair of eyes widened with realization. The Gunslinger didn't kill the Lich, Luke did. He was the anomaly. He wasn't supposed to be here in the first place.

*CRACK!*

Startled, both of them look down to see multiple glowing fractures appearing on the floor. The cracks spiderwebbed into the entire room was breaking down. As the floor crumbled, The Gunslinger desperately reached for his son's hand, only for his body to fail at the last second, shattering into pieces of fine glass. Luke only watched in horror as he fell into the white abyss.

IMPORTANT! PLEASE READ!

Author's Note: WHOOOOOOOOO! FINALLY! The first chapter of the story is finally rewritten! Took me sooooooo long to plan this out. Now, onto the main issues. I know taking out the guns from the Gungeon is a huge blow to you guys. I'm tried my best to keep it the story, but the plot I have in mind can't include them. Sorry. Besides, the guns are overpowered anyway. SO! To make it up to you guys, I'm considering writing a separate fic where the RWBY cast will be interacting with the guns from the Gungeon, starting with guns first and items second. If you like this, please send me a PM or a Review. I know there is a poll but I'm too lazy to figure out how it works. ALSO IMPORTANT! If anyone is willing to Beta for me, please let me know by either PM or Review. Thank you so much for taking the time to read this fic and I hope you have a wonderful day. PEACE!
