AN: Some of you may wonder why Sean is able to carry the autocannon despite it being twice the size of a normal person, and why it did not rip the two Grimm into shreds.
Well the first is that there are cases of stronger Guardsmen carrying Autocannons themselves and firing it, it's not unheard of. Plus as mentioned Remnants Gravity is much lighter than Catachans so everything is easier to carry. And the other effects will be seen this chapter.
The second is that I did not want to remove the accomplishments of team RWBY and JNPR by simply having Sean walk out and be like 'Lol your dead'. But do not worry there is plenty more chances for him to utterly destroy the Grimm with his plethora of death dealers.
As for why the Jungle Fighters? I though since they live on a planet that has fauna that makes Remnant's Grimm look puny and laughable in comparison, and they are all 80s action movie/ 90s first person shooter characters one would fit in the RWBY verse rather well…..Barring the obvious "Kill literally everything attitude."
Sean sat in this world's airship called a Bullhead across from the redhead he now knew as Ruby Rose. Her and the others had introduced themselves after offering to take him to this Beacon Academy. But apparently they were being monitored in some sort of test so the Headmaster had found out and sent a ship to pick them up. Along the way he was questioned non stop by Ruby about all of the weapons on him as the others watched in amusement. He would have found it annoying had he not been exactly like that at her age…...ok he is like that now. But hey guns are badass they make things explode into bloody piles of gore. Though apparently the Grimm, the creatures he had shot and killed, did not bleed. That was a rip. But his sadness at the monsters not exploding into bits a blood and bone aside he was still being questioned by Ruby while in the ship.
"How do you carry that thing? It is twice your size." She asked about the Autocannon.
"It is normally meant to be mounted but some of the more muscular guardsmen can carry it around. Though it is actually pretty light on this planet in comparison to when I normally try and lift it." Reaper answered while looking his Autocannon (Which took up a good bit of room on the ship) up and down. He had noticed it earlier but now he really got a feel for how easy it was to carry everything. He wondered what would happen if he punched something? That would need to be his next test, smash one of these Grimm's face in with his fist.
"Really?" Ruby asked curiously as she went to try and lift it. She huffed and groaned and tried with all her might but alas the cannon was not moving. Yang, the blonde girl with the large chest, then began to giggle.
"Come on Rubes show that cannon who's boss." She encouraged Ruby, who still had made no headway into lifting the gun. As she was doing that the blonde boy if the group, a kid named Jaune Arc, spoke up.
"Sooo uh, you use as sword as well?" He asked, making a note to the Devil's Claw on Reapers back. Sean looked at him and saw that he had a sword in a sheath at his side as opposed to the others who all had weird gun-melee weapon combos. Smirking a bit Sean pulled out his Devil's Claw, startling Jaune. That kid would have died so fast on Catachan it would not even be funny.
"It is not a sword, it one of my knifes." He told the blonde boy as he eyed up his four foot long knife. Everyone gave him looks of exasperation and deadpanned at him.
"That is not a knife. That is a sword." Blake, a black haired girl with a cat ear bow on her head said. With a blank look. Sean snorted and looked at her.
"Maybe for you. But to me it is a knife that I use to brutally kill whatever gets into melee range. That or this." He told her while pulling his Fang from his boot. The 20 inch long knife only got him even more deadpanned looks. Except from Ruby, who looked like she was about to attempt to grab it. He quickly shot that idea down.
"You grab any of my knifes and I paint this Bullhead with you blood." He very cheerfully told her. Ruby dashed into Yang's arms who shot him an evil look.
"Hey! That was not cool and uncalled for." She yelled. Now here is a quick explanation on Catachan beliefs. The Fang is a Catachan's best friend, he would sooner give up his arm then give up his knife. That and the fact they are born survivors, him having that skull tattoo on his arm means he has been serving and surviving in the guard for five years all, and thus has grown quite attached to his weaponry and the life he lived, cumulates into a contradictory combination of reckless bravado and paranoid caution and constant vigilance. In other words, unless that Catachan is dead or he trusts you with out question, you are not getting that knife.
"Well then she shouldn't be reaching for people's knives. Especially mine. Doing that will drastically shorten your lifespan." Sean stared down Yang. She glared at him even more and retorted.
"You were fine with her messing with your damn cannon!" She yelled out. Sean raised one finger and pointed something out.
"She can mess with the cannon all she wants, but as soon as anyone touches my knives their life is forfeit." He said in a very cold tone, disturbing everyone in the cabin. It was awkward silence for a bit as Ruby still sat in Yang's arms. Eventually an older red haired girl named Pyrrha spoke up.
"Sooo you were in the military?" She asked looking at his attire. Sean slowly turned his head until he was making eye contact with Pyrrha. Really? What kind of stupid ass question was that?
"Noooo, I just have the outfit, weapons and the skills of a veteran soldier from knitting." He sarcastically drawled.
"You don't have to rude about ya know." The white haired girl named Weiss told him. She was dressed in an all white dress and gave off the feel that offworld officers and Commissars that had the shit luck of being assigned to the regiment had. Though most of them ended up "Fragged"...by the Catachan under their command because they made the mistake of trying to tell them what to do. Last mistake they ever made.
'Really, the obviously 'higher than thou' girl was going to rip on him for being slightly confrontational? Rude.' Sean thought as he sticked his tongue out at her.
"Oh bite me bitch." He spat. The only two people who had not spoken up were some black haired emo looking boy and an orange haired bubbly girl. Though they just looked content to watch. Weiss was about to open her mouth and make a comeback but suddenly something slammed into the side of the Bullhead. Claws tore through the side of one of the doors as one of the Grimm types that Reaper had blasted with his shotgun earlier stuck its head in and roared. Jaune let out a scream that would be more fitting form a small girl as the Grimms head emerged right next to him and Sean. Unfortunately for the Grimm Sean was the first to act, and out of everyone in the Bullhead he was the one you wanted least to come after you. especially when he was pissed. Which he was right now due to having to deal with these people who would never understand why he was the way he is, and they never could.
Rising to his feet Sean let loose a right hook that connected with the lycanthrope like creatures head. Sean had gotten the answer to his 'what if I punch something' question. The answer was that they got royally messed up. The wolf's bottom jaw snapped as Reaper the grabbed the Grimm by the head, pulled it into the Bullhead and began to rain down punches on the creature's head. Sickening cracks were made each time a blow landed, one after another. The wolf made a claw swing for Reaper but he ducked under it and redrew his Fang. Grabbing the offending arm Sean cut it off at the shoulder and then impaled the Grimm upwards through the mouth with the knife. As the Grimm's life began to fade, and with the knife still in its open mouth Sean looked the Grimm in the eye and spat at it.
"I have faced butterflies that put up a better fight than you." He said. Then with one quick motion he jerked his knife upwards and snapped the Grimm's neck. The monster began to fade away into nothingness as he stood back up and looked at the people in the cabin. All had drawn their weapons but had not gotten to react. Though they did get an excellent seat for that show Sean just put on. Letting out a huff Sean sat back down and looked at the group of wide eyed people.
"What?" He asked in annoyance. For the rest of the trip Yang asked him about if his Semblance was like hers in that she had super strength. He had replied that he had no idea what that was but he was just a strong bastard. That lead to a question of if he knew what Aura was. Once again he had no clue what that was, and so Ruby, Yang, Weiss, Pyrrha and pretty much everyone but Jaune gave him some weird story about how his soul was some kind of power source that protected and gave strength to humans and faunus, whatever the hell those were. All in all the explanation left Sean thinking that he was on a planet made of all psykers and that he was boned if one turned into a daemon then started a chain reaction. One or two deamons he can handle, a planet not so much. Though, apparently, he had Aura so it couldn't be that cause he was not a psyker. At least he didn't think he was. Actually now that he thought about it he had never heard of a Jungle Fighter psyker before. Intresting.
Soon after the group had explained to Sean the basics of what was the weaponizing of one soul the Bullhead landed at this Beacon Academy. It simply looked like a giant white castle in Sean's mind. But why not right? He was born and had to survive on a jungle planet with a 75% mortality rate before ten years old. Here late teens learned how to fight relatively docile monsters, by his standards, at a giant castle. Yep, totally fair. Sean grabbed his Autocannon and threw it across his shoulders as he walked off of the Bullhead. Standing not far away was a man in a green suit with grey hair going over his eyes and a pair of glasses. Standing next to him was a blonde woman wore what looked like a school teacher crossed with a witch. Both were staring right at him. The hell did he do now? Step off the damn ship wrong? After the grey haired man told the group of students to head to the amphitheater and that he would be there shortly, he redirected his attention to Sean.
"So you are the mysterious soldier we saw in the video." The man did not ask that, he stated it.
"Video?" Sean inquired. The woman pulled out what looked like a data pad and showed a screen of him blasting the scorpion and bird with the Autocannon, then another of what he just did to the wolf. They had cameras set up there? Damn, hate to have the job of setting them all up.
"Ah, that. What of it?" The man took a sip from a mug he had just pulled from absolutely nowhere.
"Well I can currently tell you no weapon like that exists here nor does any military unit that dresses the way you do. So I will be direct. Who are you and where are you from? What are your intentions here?" The man inquired. Sean had to deeply resist the urge to flip him the bird and tell the man to 'Go fuck himself" for trying to order him around but stopped himself.
"I am corporal Sean "Reaper" Basilone formerly of the 7th Catachan Devils of the 75th Catachan Regiment. I am from the planet Catachan, a death world in the Imperium of Man. As for intentions? I plan to try and find a way to reconnect with my regiment. If that is not possible…..well i could always kill those Grimm for fun. Emperor knows that dying from one of those would be an embarrassment." Sean informed the man. Both of the adults looked at each other before the man turned back towards him.
"Well I can tell you I have never heard of the Imperium of Man, nor any planet called Catachan. In fact we don't have much knowledge in the way of astronomy as it is not that useful in fighting the Grimm." The man stated, and then took another sip from the mug.
"Welp shit. I had figured but it's upsetting to hear." Sean mumbled. The woman then look scandalized and yelled at him.
"This is a school! Watch your language around the children!" Sean gazed at her in aggravated silence and the yelled back.
"I am 18 you blonde shit head! That's what? A whole year older than those "kids" that just got off the ship with me?" Sean said while using air quotes around kids. Both of the people he was talking to looked surprised at that. Well the guy did. The woman looked ready to start choking him…..and not in the fun way either.
"18 huh? With your physique and tattoo I'd figured you for a man in his mid to late twenties." The man commented.
"My home has a much higher gravity than here, and survival is very tough sooo muscles. And the tattoo I got for serving and surviving for five years in the regiment. " he informed the man.
"Five years huh? So you enlisted at 13?" The man asked. Nope, not going to answer that one.
"Drop it." Sean told him angrily. The blonde witch woman started to open her mouth but was stopped by the man. He then looked at Sean for a few seconds before speaking.
"Would you like to join my school?" He asked. The woman let out a sigh as Sean gave him the 'Where did that come from' look.
"Why would I?" Reaper inquired. He would at least hear the man out before laughing in his face.
"You are stranded on a world that knows nothing of the place you come from, you have no means of contacting or reaching this Imperium, the Grimm that you fought threaten to extinguish humanity, and since you enlisted into your military at 13 and, from your own admission, come from a very rough place, you more than likely lack sufficient people skills to make it out on your own. That and I can offer you shelter, food, education, and the opportunity to be a defender of humanity." The man spoke conviction lacing his voice. While Sean hated to admit it those were some good points. Though he could take the people skills comment and shove it up his ass. His people skills were great dammit! The last part though made him laugh. He would go from fighting enemies that would raze worlds and threaten the entire Imperium to helping a humanity on some weird ass planet whose enemy kind of sucked. But at least he could continue fighting. Hey you take your victories where you can.
"One condition though." Sean spoke up after a few minutes of thinking this over. The man raised an eyebrow and motioned for him to continue.
"This thing is going to need ammo, and I have the perfect idea for what it should be." Sean motioned to his Autocannon. The man nodded and held out his hand. Sean eyed it for a bit then slowly shook it.
"My name is Ozpin, headmaster of Beacon and this is Glynda Goodwitch. Welcome to Beacon."
