RWBY: Dark System

Adam spins around his katana with skilled and precise movements then he strikes down Shadow who blocks the sword with his bare elbows. Shadow's Sharingan eye's open wide and he quickly copies Adam's moonslice semblance. Within seconds he could feel his aura rising, his speed increasing, and his defense reach peak levels. Adam's semblance could counter any attack and reflect the attack ten times over back to its opponent. That's why it was so easy from him to cut down that red and black 'Atlesian Paladin-290 mech' when it shot a laser beam at him and he absorbs the beam inside his katana then slices the colossal mech in half like butter(Referring to the RWBY: Black Trailer). His semblance was something that Shadow had wanted very badly, as well as his faunus traits. You may be thinking that he could have made the semblance up in his Dark System, but it wouldn't be the same. Getting the semblance from its primal source was a far more effective idea.

Shadow pushes back Adams katana with his newly acquired semblance [moonslice] and then fuses it with his dark thunder. The platform below him starts rumbling crazily as if there was an earthquake nearby, all the blackish mountains around the Land Of Darkness starting crumbling, mother nature was at the mercy of the powerful wrath of Shadow's fused attack.

Sparks of black colored electricity buzzed and crackled around his entire body. Adam bolts towards Shadow and uses moonslice again, "Aaaaaaah! Time to die foolish boy!" He roared. "Let's see you counter this!" Shadow shoots out a condensed ball of blackish and crimson red thunder bolts towards Adam. His fusion attack was massive! A barrage of thunderbolts explodes up against Adam who tried to cut through his blast. Adam's moonslice semblance actually slashes through half of the dark thunder ball, but it was already too late. Shadow knew in order to defeat Adam he would have to combine moonslice with the strongest of his own semblance and fire it back at him. A large thunderous explosion filled the air, black thunder sparks exploded nearby mountains into a billion chunks of shattered rocks. "Gaaaaaah!" Shouts out Adam in pain as his body rolls across the floating platform.

'Who in the world is this boy?!' Cinder clenches her fist and gritted her teeth. Emerald gasps in disbelief. Mercury just smiles and punches his fist together. Neo is clapping her hands and rooting for Shadow to win.

'System how do acquire Adam's Faunus traits?' Shadow walks towards Adam who his clinching his broken ribs.

[You must digest his blood]

'Easier said than done' Shadow transforms his teeth into razor-sharp grimm beowolf teeth. Adam gets up and his white fang leather jacket is torn to bits. His whole body is covered in bloody scar marks, electric current sparks still circulated through his skin, his skull grimm mask is cracked. He is pissed more than ever and for the first time, Shadow sees one of Adam's eyes.

'What the fuck?'
