RWBY: Dark System

'The choices laid out were very powerful, but they had their drawbacks. Having to much power isn't always a good thing, especially if you don't have the stamina and willpower to control it. So I had to break down my decision into three main factors of combat; Attack, Defense, and Speed. First I want to create a semblance, there were two anime shows which shocked me of powerful vector manipulation was; Accelerator's (A Certain Magical Index) and Elfen Lied. Vector manipulation can manipulate the vectors of matter and its related energy, the ultimate level of this power is space and time distortion as well as gravity manipulation like making objects and living beings float in the air by making a gravity field. While the vectors from Elfen Lied were mainly used for attack, an infinite army of invisible hands which can rip part any species body into shreds of bloody meat. Maybe I could fuse Raven's portal magic with vectors. So I decided to create a new semblance called 'Vector Portal' which had powerful offensive and defensive purposes. I could repel anyone's attacks and I could teleport anywhere I want by making portals out of thin air. Next choices were very simple Dark Thunder(Because who wouldn't want to be like Thor? and the attack is insane on this semblance can't wait to use it) and Nuclear( Perfect for recharging my body to peak conditions since I can already absorb negative energy as a demi-grimm. Everything is ready. Let's do this!" Shadow quickly chooses his options and opens his eyes only to be greeted by Adams' fist.

[Semblance]

Darkness- ( I still need to see how this is activated. I haven't used it yet.)

Vector Portal- (Esper and Mage abilities gained)

Dark Thunder- (Thunder Element gained)

Nuclear- (Fire element gained)

Shadows [vector portal] semblance quickly reflected and repel Adam's attack and sent him flying. Two swirling blackish portals were seen floating behind Shadows shoulders.

"Who the hell is this kid!?" He spun around his red katana and slashed away at Shadow who dodge each and every slash. Shadow used his [dark thunder] semblance on himself, he was now as fast as the speed of light. Adam was the fastest and most cunning person out of all of the villains due to his Faunus traits, but right now Shadow was equally on his level. They both kicked and punched each other at an insanely fast rate, Cinder couldn't even see what was going on.

'I wonder if I can steal Adam's Faunus traits? I always wanted to be a Faunus. Being a human in RWBY would be boring and a disadvantage. Right now I am half grimm and human, what if I were half grimm and Faunus?' Shadow's eyes widen at the thought.

"You're pretty fast kid. But I am done playing around. I am glad I don't have to go easy on you I have been itching for a real right! I am pretty sure no one will care if I kill you!" Adam used his semblance 'Moonslice' and cuts right through Shadows dark aura, "Gaaaah!" He yells out as his body rolls across the floating battle arena. The walls surrounding the chamber room and battle arena started to fold apart and disappear. Shadow and Adam were now outdoors as the floating platform below them shifted and spun towards the Land of Darkness. "Tch. I am done going easy on everyone. I am going to steal your body and your semblance you cocky bastard." Shadow stares at Adam and activates his Sharingan. His black and red combat leather jacket cooly sways with the wind.
