anywho, i'll drop this;
this is the same guy from the og games, taking down hordes that have previously wiped out entire platoons of trained marines with access to weaponry that could have easily teared apart said demons.
This is something that quite literally every character in RWBY can do, even the low-skill fodders
Ravaged through hell for eons killing demons without stopping.
A good feat of stamina but not really a good feat of skill when the vast majority of demons the Slayer encountered were several thousand times weaker than him
killed the strongest titan with his bare hands, which was larger than 100 meters tall, leaving it as nothing but a skeleton
Capable of dodging 10 to 100s of projectiles and homing projectiles at the same time
Defeated an entire arena of Night sentinels. Warriors who exist within a society who has only known war. With their experience in combat having been taking down Ancestrals, the predecessors of the Titans without mechs. These men are hardened and strong warriors who were vastly above the physical strength the marine was capable right after being captured. His power reacted to their strength,his will matching theirs and pushed through their ranks despite these warriors having years and years of swordsmanship training.
until we meet again next time!
Okay so:
At the bottom of the skill chain is aura users as a whole. While every living being in RWBY technically has Aura, actually being able to utilize it for things such as defense, regen, and senses requires years of training and a high enough degree of martial skill (and yes you actually need martial skill for it) that only a small percentage of the population of the entire planet ever become skilled enough to utilize their aura. Of that small percentage, an even smaller percentage ever become skilled enough to manifest/control a Semblance (yes semblances are also skill-based). To reach this small percentage comes to the second half of the bottom of the chain: Almost every character worth their salt in RWBY has spent their entire life training in combat and can fight hordes of Grimm with little issue (Almost because Jaune exists). The entirety of the main cast of RWBY was initially enrolled at Beacon Academy, one of the most prestigious combat schools in the world, with almost everyone who was accepted there having been trained for almost their entire life to fight monsters, and each one that was not professionally trained requiring a skill display overseen by Ozpin, who has the composite skill of several thousand professional huntsmen that he accumulated over his immortal lifetime. Thats the baseline for skill in the verse.
Before the Beacon Arc Ruby had been personally trained by her uncle Qrow in combat and as a result she was noted as always excelling above her peers in combat training. At the start of the series Ruby was at a level of skill that even though she was two years away from being eligible to join Beacon she was admitted due her combat prowess impressing Ozpin, with him noting that she was already a master at wielding one of the most dangerous weapons ever designed. In combat Ruby is capable of taking on entire hordes of Grimm on her own and walking away without a scratch and utilizing the different functionalities of the Crescent Rose, such as the massive recoil from the rifle aspect of the weapon and the weapon's transformative capabilities, in tandem with each other and her Semblance in order to maintain an edge over her opponent. Basically every named character is around this level of skill in the early seasons.
Above the early cast is Velvet. Velvet is able to perfectly and instantly mimic the exact moves that she observes other people use in combat as well as utilize multiple different fighting styles simultaneously, both armed and unarmed. Thanks to her weapon, Anesidora, Velvet is also able to copy fighting styles that utilize weapons, and she is able to wield the weapons that she copies just as effectively as their original user. To date that we know of, Velvet is able to simultaneously utilize the fighting styles and weapons of Ruby Rose, Yang Xiao Long, Weiss Schnee, Blake Belladonna, Nora Valkyrie, Sun Wukong, Penny Polendina, Coco Adel, Peter Port, Reese Chloris, Fox Alistar, Vega Bleu, Yatsuhashi Daichi, Russel Thrush, Roy Stallion, Neptune Vasilias, Brawnz Ni, Bartholomew Oobleck, Flynt Coal, Edward Caspian, and Scarlet David. Of note, every person listed spent their entire lives training in combat and several of them are professional huntsmen with decades of combat experience.
Moving up the chain we have Nebula Violette, who not only outmatched Velvet in a 1v1 test of martial arts skill, but was directly stated by Velvet's team, who spent years working alongside her, to be more skilled than Velvet in combat despite Velvet mixing numerous fighting styles to try to throw her off in their fight. Above her is Pyrrha Nikos, the skill god of the Beacon Arc. Pyrrha is one of the most skilled students at Beacon Academy, having won every combat tournament she has entered since she was a pre-teen due to both her mastery of combat and mastery of her semblance, being able to apply it in combat completely undetected and having done so in almost every fight she's been in for over a decade, doing so with such skill and precision that she has lead many to believe she is untouchable and invincible as no one has been able to even land a single blow on her in her combat career despite her having gone up against hundreds of opponents with a variety of fighting styles, weapons, and unique abilities. Even without her semblance she has shown the ability to quickly and easily adapt to her combat situation and analyze her opponents while fighting and changing tactics to suit the situation she is in, to the point that as casual training she regularly took on entire teams of huntsmen solo without the use of her semblance and never lost once. She has shown extreme accuracy, being able to hit moving targets from hundreds of meters away and strike vital weak points on an opponent mid-combat both with and without the aid of her semblance. She is also highly skilled at using her weapon's multiple forms in combat, being able to switch between forms several times in rapid succession to both deliver rapid attacks and counter others simultaneously.
Then theres Mercury. Mercury is a veritable master of close combat and one of the best assassins in the world, having spent his entire life since he could walk training in pure martial combat to make up for his Semblance being stolen by his father. He is shown to be a very acrobatic and agile fighter who relies upon quickly overpowering his opponent with complex kicks that imply a near-mastery of martial arts that resemble Tae-Kwon-Do. He is also capable of a break-dancing style, similar to Capoeira, and makes use of Muay Thai as well. Despite his focus on kicks, Mercury also uses his hands to grapple, block or redirect enemy attacks. His experience and skill are aggressive and effective enough to drive even fighters of a high caliber, like Pyrrha, into a defensive position, with Word of God confirming that Mercury would defeat her if he fought her seriously. Despite the presumed awkwardness of his weapon's ranged capabilities he is a skilled marksman, able to shoot a phone out of a person's hand from a good distance away, and is proficient at using the many different forms of projectiles at his disposal to keep his opponents off balance. Mercury is also known to be observant, tactical, and analytical, able to notice and deduce the capabilities and limits of Pyrrha's Polarity Semblance after she uses it once during their brief fight, despite Pyrrha using it extremely subtly in combat and having spent her entire life honing her ability to hide her Semblance and its mechanics from her opponents and the general public.
Above Mercury is Adam, who is skilled to the point that Mercury alongside his two teammates, Cinder Fall (Who can turn people to ash on contact) and Emerald Sustrai (Who can mindhax and perception hax people), saw him as a major threat, to the degree that Cinder went out of her way to steal one of the strongest sources of magic in the world before confronting him. Yang in this key is able to match him in CQC.
Now that the general level of skill has been established, Yang's specific feats:
- In the early series she casually weaved through automatic gunfire on multiple occasions, dodging homing missiles and shooting rockets out of the air with her energy bullets, and was able to read and outpredict the attacks of two of the best assassins in the world fighting her in tandem on two different occasions. She personally designed and built her gauntlets to perfectly suit her initial aggressive combat style, with each punch she throws priming another shot so that she is able to keep constantly firing at the opponent or empowering her punches with explosive energy. Additionally, she mastered maneuverability with her gauntlets to the point of letting her almost fly with them by using the recoil to launch herself as well as being able to change direction on a dime to keep opponents off-balance. Of note, despite all of these things, her fighting style was described by several pro-huntsmen as sloppy, embarrassing, and overly aggressive.
- After the fist arc of the show, Yang went through a timeskip training arc with her father, a veteran huntsman skilled enough in hand to hand combat to pick apart her fighting style to find all of her flaws in order to mentor her into becoming a more skilled, less bullheaded fighter. As a result of this Yang outgrew her overly aggressive former fighting style, adopting a more refined style that incorporates more agility and dodging rather than just tanking hits to fuel her semblance. She regularly displayed the ability to dodge and block attacks she didnt even see, and rather than her former style of activating her semblance as soon as possible to overwhelm the opponent with raw power, she instead stockpiles it for as long as she can in order to maximize the damage she can do while working throughout the fight to get the opponent into a position where they cannot reliably dodge her attacks when she activates her semblance.
"The age of his reckoning was uncounted. The scribes carved his name deep in the tablets of Hell across eons, and each battle etched terror in the hearts of the demons. They knew he would come, as he always had, as he always will, to feast on the blood of the wicked. For he alone could draw strength from his fallen foes, and ever his power grew, swift and unrelenting." -UAC Report file
He ravaged through hell for a few eons before 2016 doom, stated a handful of times iirc. i'll try to get more of em, slight busy doe.
Ye, like i said, eons tends to be a purposely vague, catch-all term for an unknown but long period of time, it doesnt just automatically mean billions of years, he would have to be almost as old as or older than the Earth itself for it to be literal.
