Welcome to the first official chapter. This will explore how Caboose had ended up in Hell in the first place. Expect everything to be too cliches because this is Caboose we're talking about.

If you're wondering what scenario this would be after hearing that Seasons 15,16,17, and Zero are just simulations, the former three are canon. In this storyline at least because it's one of many scenarios that has been brought up. You'll see why.

This chapter's opening is inspired by Ac3 Production 'RvBvRWBY: A Soldier's Debt' that gives me the plan of seeing how it would unfold.

Caboose's Guide to make Friends in Hell

Guide One

How I got here?

Premise: Now you're wondering how I go to that place right? Well, here it is!

Day hit Iris as everything seemed to be peaceful as the daylight shinned over at a certain base. Well, not really. There were many sounds coming out from within, mainly from Sarge scolding Grif. "Captain Grif! How many times do I have to remind you to not sleep while on the job!?"

"What job, Sarge!?" Grif groaned. "Standing around all day and just bickering about?!"

"You're supposed to be the one in charge of the ammunition!" His Commanding Officer barked. "We need that safe if we went to war!"

Hearing his caused the Orange Solider to groan at this statement. It was during this time that his teammate got close by. "Grif, I really think you should play along." Simmons whispered to him.

"Play along?" The lazy soldier can't believe what he's hearing. "We are retired and that doesn't mean that we have in stock." And that caused Sarge to raise his shotgun at his face. All he could do was to sigh. "Fine, I'll go get more fucking ammunition." He sarcastically said before walking towards the Armoury.

As this was happening, Carolina inserted a needle onto Washington's neck while he sat on the couch. Once its content had been pushed, he pulled it away. "How are you feeling?" She asked.

"Fine, I guess." Her former Freelancer Partner responded with a dry tone as he put a hand around his neck. "Though, it sucks that I have to take this daily."

Doc, who stood nearby, looked at him. "I'm sorry to hear that. But that was the best medication that Simmons and I could create for your Cerebral Hypoxia. There is no other treatment like that."

"Unless you want to pay for medical bills!" O'Malley commented before laughing.

"Yeah, I know how expensive that is," Donut spoke as he laughed it off.

While the group was bantering, Tucker scanned around the room and noticed that one particular person is missing. "Has anyone seen Caboose?"

Sister could answer that question. "He's back in the base playing catch with Freckles."

"Right?" The Aqua marine spoke with uncertainty. Ever since he had gotten Freckles a new body given by their allies in Chorus, along with the batteries provided by Loco, the blue idiot has been constantly playing with his pet ever since Wash got discharged from General Doyle's Hospital. It didn't annoy them.

Until they saw that he had been playing with it straight for over a month. Which raised concern for everyone as Caboose didn't get a proper rest.

"So, you reckon I go outside and get Caboose?" The Aqua Marine asked the rest of the Blood Gulch Crew.

"Eh, I think Caboose can do that on his own," Sister assured him. "But if you want to…"

"Fine. I'll go, but Caboose better gets back the moment I tell him." He groaned as he walked out of base to go and go get his friend.

-Scene Change-

In the back of the Base of Iris, Caboose had a stick in hand that he could throw far away. "Alright, Freckles. Catch!" He immediately threw the stick into the air.

"FIRING MAIN TARGET!" Freckles spoke as it raised one of its arms and fired at the stick, completely blowing it up.

Though it had been destroyed, this made the blue idiot happy as he put a knee on the ground and petted the small robot like a pet. "Good boy, Freckles."

It was indeed a fun day to play fetch with his Pet. He looked to where the sun was, and it was beginning to set. A sigh escaped his lips, and he looked down at his Pet. "Freckles, today has been great, right?"

"AFFIRMATIVE!" His pet robot replied back.

"Hey, Caboose!" The blue soldier turned to the side and saw Tucker. "We're going to be having a Korean BBQ tonight! You better head back inside quickly if you—"

"Okay!" His idiotic teammate spoke in an instant.

"You better be." Tucker reminded him. He is aware of how he sees everything falls into two categories. Either he doesn't understand it, or he doesn't care. "You don't want to miss out on the food!"

"Okay!" Caboose spoke as he saw Tucker heading back inside. He looked down at his Pet. "Let's go, Freckles, we don't want to miss out on the awesome food!"

"LET'S GO, MASTER!" Freckles spoke as he lifted from the ground and held close by Caboose.

Speaking of the individual, Caboose saw a door behind the base. By the looks of it, it had been made recently. "Look, Freckles! A door that has been made! We can just pass by."

His Pet didn't share the same feelings as him. "IT SEEMS SUSPICIOUS."

Caboose looked down at his Pet. "Nonsense?! No, I do not think so! We can just enter the base from behind and meet everyone inside!" With that decision he made without considering it, the blue soldier walked up to the door and immediately stopped. He looked over and wondered how to open it. "Um, how do I open it?"

"THE HANDLE, MASTER." Freckles answered.

"Oh," The idiot uttered as he saw the handle. He looked down at his Pet once more. "Thanks, Freckles!"

"YOU ARE MOST WELCOME!" His Pet commented.

Caboose put his hands on the handle and immediately opened it. He seems oblivious as the inside didn't have the same contents from within the base when it opened. "Let's go, buddy!" Caboose immediately took a step in and walked inside. Unknown to him, as he entered through the door, it immediately closed in on itself and disappeared.

Back inside the base, the Reds and Blues surrounded the table as a grill had already been set up and meats on top of it. Looking at the food surrounding it, they seemed to have already begun having Korean BBQ. Well, it didn't seem like none of them had their meats cooked.

Why?

"Hey, Fatass!" Simmons looked over to his friend. "You better save meat for us and not horde it for yourself! We spent our hard-earned cash on this!"

"Yeah, I'll save some for the rest of you!" Grif spoke while gesturing his hand.

"You better," Carolina warned.

After a few meats had been cooked, which Grif had most of, the Reds and Blues began to devour the meats and sides like Vegetables and rice. They seemed to be delighted with the food that they had in their mouths. "Mmm, delicious!" Donut commented.

Sister could say the same. "This is what I'm talking about! Korean Food is fucking delicious. More delicious than the ones I ate during my bi-phase."

"Yeah," Doc commented despite seeing how unhealthy it was before he did a double take on what he had just heard. "Wait, what!?"

As this was happening, Tucker saw that everyone was enjoying the meal. Well, almost everyone. He'd realise that a particular blue idiot was missing. He scanned his surroundings again and saw that Caboose was nowhere to be found. "Where's Caboose?"

Everyone stopped eating and looked around to see their blue idiot, nowhere to be found. "He should be here right now. Didn't you call him?" Carolina asked the aqua trooper.

"I did," He reminded her. "It doesn't take that long for him just to get here."

"Maybe he's gone to the bathroom," Washington spoke as he ate the cooked beef Carolina had given him.

This caused the trooper to sigh at his words. He put his metal chopsticks down and stood up. "Alright, maybe he didn't hear me the first time." He walked away from the table and headed outside to get Caboose.

"Caboose! Where are you?!" Tucker called out to his idiotic teammate while heading to where he was last seen. "You better…not…be…" As Tucker arrived, he saw that Caboose and Freckles were nowhere to be seen. The Aqua soldier had to be sure that his eyes weren't playing tricks on him. "Caboose?"

No response was heard.

Tucker looked around once more before he started to panic. The blue idiot seems to have disappeared without a trace. This made him return to base to inform everyone of what happened.

As he headed back to base while continuously uttering 'fuck' until he stopped himself as he went to the table. He saw everyone looking at him with a curious look behind all their helmets. "Tucker, what was all of that?" Carolina can't help but ask.

"Caboose disappeared along with Freckles!" The Aqua-coloured Trooper informed the group, causing them to stop feasting on the food.

"WHAT!" Washington can't help but shout loudly at this.

"How the Hell did Caboose just simply disappear all of a sudden!?" Simmons asked until he realised something. "Oh right, he tends to do that right under our noses."

"Yeah, and I am not up for the task for looking for him." Grif commented as he scarfed food into his helmet tube.

"Perhaps he just wondered about." Donut spoke as he took a bite off from his food.

Carolina thought about it and knew that they had to go searching for the blue idiot. "Alright, Tucker. We'll go look for him once we are finished." She spoke, trying her best to hide her annoyance at Caboose's antics. "He can't be that far right?"

"Don't worry about it. He probably encountered a math problem and is stuck." Tucker said, having hope that Caboose had just ended up in a place similar to the Dark Place.

-Scene Change-

"Hey…" Caboose uttered as he found himself in a room that had a regal look and had a large bed along with a Window that overlooked into a city. "This isn't the bathroom!"

He began to randomly walk in a direction. Along the way, Caboose walked passed a mirror, which immediately stopped and walk back where the mirror was. He looked at himself and saw two changes.

The first was his armour. It looked significantly different to the one he wore back in Iris. It seemed to be similar to the one he wore back in Valhalla, but it seemed to be bulkier yet practical for a soldier to wear. The second is his pet, Freckles. He is nowhere to be found, which made him panic.

"Freckles!?" Caboose looked around the room to look for his friend. "Freckles, where are you!?"

"RIGHT HERE." A familiar robotic voice called to him.

Caboose immediately grabbed something from his back and saw that Freckles' voice was in the MA5D Assault Rifle that he'd used during his time in Chorus. "Freckles, you're here! I got so worried that you disappeared!"

"AFFIRMATIVE!" The robot spoke.

The blue idiot also noticed that he had a Sniper Rifle System 99D-Series 2 Anti-Matériel on his back upon looking at the mirror. It took Caboose a millisecond to realise that it was the very same one that Church used before his eventually departure, which saddened him. "Church…"

"Meooooowwww!"

Caboose looked down and gasped. He saw a black and white cat that was looking up at him with one huge eye. Almost immediately he started to gush at the small animal. "Oh my GOD!" Caboose picked the cat up and hugged it while rubbing his helmet on its head. "You're the cutest thing ever! We can hang out and play and walk and talking…"

Unknown to him, two individuals, who are girls and slept on the large bed, woke up due to the noise Caboose made. The first one had long, blonde hair, groaned as she sat up from her bed. "Ugh, would you please stop…" She opened her eyes to reveal red irises with light yellow sclera and saw what was in her room. "Being…loud…" Her eyes widened and began to shake the other girl. "Uh…Vaggie…?"

"What?!" The other girl spoke, having been awakened from her sleep and was annoyed that it got interrupted. She sat up and groaned. "I'm already at my limit, Charlie, from….the….noise…"She saw the other girl having a horrified look on her face. "What are you looking…" She asked while turned to where the other girl was looking at and stopped talking. It was at that moment that she, too, had the same look as the other girl.

Caboose continued to rub onto the cat's face until Freckles spoke. "MASTER, THERE ARE TWO PEOPLE IN THE ROOM!"

This stopped the idiot from what he was doing and looked around. "Where?" He asked.

"ON THE BED." His pet answered.

Caboose turned to where Freckles had pointed, and he saw two girls staring at him with a mixture of surprise and horror on their faces. It is as if they had not been expecting him. Though, in Caboose's case, he seemed to be thrilled to meet new faces. He put a hand up to the level of his head and waved friendly at the two. "HEEEEEEEEEEELLLLLLLLLLLLLOOOOOOOOO! Would you two like to be friends!?"

Preview: Yes, that's exactly how I met two people. Charlotte Morbinstern and Baggie! However, they seemed to be surprised by my sudden appearance, which is understandable considering that they were sleeping? I wonder what other people I can meet in this strange new place.

Well. It seems like Caboose had made a first impression of Charlie and Vaggie. By being in their room all of a sudden.

Anyway, as for the design of Caboose's Armour, I went with the Halo 3 design with the Mark V Helmet and the design similar to the Spartan Armour from Halo Infinite. I also went with the weapons with his Assault Rifle from the Chorus Trilogy and the Sniper Rifle that Church used in Reconstruction.

I hope this chapter satisfy all of you!? You can criticise this work since I feel like there are many O.O.C moments. But what do you all think and what impacts (both good and bad) can Caboose bring to Hell and its natives?
