The end of the test subjects mission has come
The ten test subjects walk through the forest until they arrive at the start of a clearing where a shuttle is landed. Night stops the group.
"So who's staying behind?" Camo asks.
"I say Volt." Brass suggests.
"No! I am not walking back." Volt states.
"Enough!" Rider yells.
"I will be staying behind, now go." Night says.
"You don't have to..." Rider begins.
"A leader must be willing to give up his life for his troops." Night states.
Rider nods and follows the other test subjects back to the shuttle.
Night arrives at the base without a scratch. He is called into to debriefing. Night enters a room with a chair. He sits in the chair.
"You stayed behind, Night." The scientist states.
The scientist's voice was projected through speakers on the ceiling.
"Why?" The scientist asks.
"It's what a good leader would do." Night states.
"Most leaders would sacrifice the weakest unit to progress." The scientist states.
"And those leaders would most likely fall to rebellion." Night responds.
"You have learned well, Night." The scientist states.
"I learned from the best." Night says.
-Present Day-
Onyx stares at the humanoid Grimm, watching as it easily towers over him. Ruby summons her locker and grabs Crescent Rose.
"What is it?" Ruby asks.
"A Grimm with aura." The Rider states.
"How is that possible?" Ruby asks.
"It's a combination of Grimm and Human DNA. Umbra had created it in an attempt to merge a Human mind with that of the Grimm, in order to learn how they think. Obviously, the test failed." The Rider explains.
"What's it doing here?" Ruby asks.
"Rubine." The Rider answers.
Ruby fires her sniper at the Grimm. The bullet holes regenerate instantaneously. Rather than focusing it's aura on a defensive barrier, the Grimm used it's aura to regenerate all wounds that are inflicted on it. Onyx charges at the Grimm and jumps over it, shooting the Grimm in the process. The Grimm turns to face Onyx.
"Fall back." The Rider orders.
"What about you?" Ruby asks.
"I'll lure it into the forest and deal with it there." The Rider states.
Onyx begins firing at the Grimm while slowing backing towards the Emerald Forest. The Grimm follows Onyx. Onyx stops after a few minutes, switches his pistols into knives, then slashes at the Grimm. The Grimm doesn't even flinch, healing the wounds immediately after they are created. The Grimm slashes upwards with it's sword, knocking Onyx into the air. Onyx lands on a tree branch, converts his weapons into pistols, and fires at the Grimm. The Grimm then rams into the tree, causing it to fall.
Team RWBY runs towards the collapse tree. Ruby feels the crystal Onyx gave her begin to pulse faster.
Onyx starts to fight defensively while he comes up with a strategy. The Grimm raised it's greatsword and quickly brought it down towards Onyx. Onyx blocks the Grimm's attack with his knives, but is forced into the ground. Onyx pushes the Grimm's blade upwards while jumping backwards. Onyx converts Redemption's edge into it's dual pistols form and fires shots at the Grimm. The Grimm regenerates the wounds immediately. Onyx finally recognized the aura of the Grimm, it is similar to his own.
I can't wear down it's aura.
It seems to be tapping into the Shadow Zone's dormant energy without being inside of it.
That allows it to regenerate it's aura almost immediately.
Onyx charges at the Grimm as it raises his arms for another strike. Onyx cuts off the Grimm's hands to disarm it. The hands regenerates, but the Greatsword remains where it had landed. Onyx dashes at the now disarmed Grimm, only to get punched in the face. The punch knocks Onyx through a tree into another. Onyx recovers and fires at the Grimm to draw it's attention away from it's weapon. The Grimm charges at Onyx, tackling him through down a hill. Onyx kicks the Grimm off of him while getting to his feet. The Grimm roared at Onyx, pushing him back with it's shear force. The Grimm tries to punch Onyx, but Onyx jumps and lands on the Grimm's fist. Onyx runs up the Grimm's arm and kicks it in the head. The Grimm's neck can be heard snapping, but immediately heals. Onyx jumps of the Grimm and fires at the Grimm, this time using his guns full automatic firing mode. Onyx watches the wounds heal, counting the milliseconds until the regeneration starts.
The regeneration is too fast for me.
But it has a weakness.
It can only heal when it isn't being attacked.
But even the slightest time in between attacks is enough for it to start the healing process.
Onyx checks his aura level, it is at sixty two percent. Onyx decides on his plan of action, watching as the Grimm recovers it's weapon.
No Shadow Zone.
That leaves my other trump card.
Onyx's stares at the Grimm with a determined glare, converts his pistols into their knife forms with his hair and eyes burning with crimson flames. Onyx charges at the Grimm with blinding speed. The Grimm swings it's blade at Onyx, but he jumps onto the sword, runs across it, and slashes at the Grimm's neck. Onyx then bounces off a tree and strikes the Grimm again with the same blinding speed. The Grimm didn't have enough time to regenerate before the next blow is made. Team RWBY arrives shortly after.
"Wow." Ruby reacts.
"He's as fast as..." Weiss begins.
"You, Ruby." Yang finishes.
"He's so fast the Grimm can't react. It can't regenerate at all." Weiss states.
As the girls stare with their jaws dropped, Onyx continues striking the Grimm with the same speed until it's weak point is revealed, it's heart. Onyx converts one of his weapons into it's pistol form and shoots the heart, killing the Grimm instantly. Onyx lands on the ground and immediately falls to his hands and knees. He checks his aura level, it is at one percent. Onyx gets up, walks two steps, then collapses.
Onyx slowly regains consciousness in the infirmary. Ruby feels the crystal Onyx gave her begin to pulse faster. She stares at Onyx and then the crystal, noticing Onyx is starting to wake up. Ruby places her head on Onyx's chest and listens to his heartbeat, it matches the pulsing of the crystal. Ruby hears Onyx say something.
"What did you say?" Ruby asks.
"Get... off... of... me." The Rider says.
Ruby quickly gets up and waits for Onyx to sit up.
"What was that?" Ruby asks.
"What do you mean?" The Rider asks.
"You're speed." Ruby clarifies.
"When I killed Night, I absorbed the portion of Shadow he had absorbed. With it came a piece of Night. It gave me some of his recent memories and semblances he absorbed." The Rider explains.
"You have our semblances?" Ruby asks.
"Yes, but using them puts a heavy strain on my body. Which is why I rarely used them." The Rider states.
Onyx grabs his left arm and begins to pull.
"What are doing!?" Ruby asks.
Onyx continues to pull until his mechanical arm is removed.
"Why would you...!?" Ruby begins.
A new arm made of crimson energy begins to form. The energy then becomes a proper arm. Onyx examines his regenerated limb.
"I'm through playing around." The Rider states, "Rubine has shown that he will not hold back anything, so neither will I. I will have to use every possible asset in order to defeat Rubine, including the Shadow Zone."
"But I thought you told Weiss that...?" Ruby begins.
"Difficulty is a matter of perspective and mine has changed." The Rider states.
"Why the change?" Ruby asks.
"That theory I mentioned ealier." The Rider answers.
Onyx opens a portal above his hand and his cane fall through. Onyx catches the cane and shortens it before holstering it on his belt. Onyx gets up and begins walking towards the exit. Ruby follows behind Onyx.
"Will I ever see you again?" Ruby asks.
"Maybe. Only time will tell." The Rider states as he phases into the Shadow Zone.
Rubine has been to the lab in Menagerie. That'll be my first stop.
