At that instant Tanner knew he could be finished by her... If she did know about his 'mutation' at least. Faster then he had earlier he used his barbed tail to stab her in the back of her knee, making her crumple in pain.
"Ya I do know." He said "but I'm cursed already"
He grew a smile as cold and evil as a black hole. Then, grabbing his sword he raised it up over his head.
"I guess it's time to break a few hearts, starting with- AAAAAHHH!" He yelled. Keith had seen the fighting and seen Tanner raise his sword to kill Ari. Before Tanner could do anything though, Keith snapped, his eyes went from Electric Yellow to the darkest Crimson you could imagine. His canines grew 3 inches, his hair sparked with electricity, and he had 3 yellow rings appear around his arms and legs, like miniature halos, but on his appendages instead of his head, his claws came out and were larger than they normally were. Tanner was flailing about, trying to get out of Keith's grip but he seen, and felt, to his horror that Keith wasn't holding him. He was suspending him at the end of a giant sword made of Water Crystal. It was 12 feet long, easy, and 2 whole feet thick, Tanner was stuck at the end of it while Keith held the sword up with one hand, as if the sword weighed nothing.
"Hear me now Tanner," Keith spat at him, his voice was deeper and had a demonic tone to it "I told you that if you tried to get at Kate that I would turn you into mulch. Now you've done worse... You shot her."
Keith flung Tannor at the nearby wall, sending cracks up the whole building. he tried to get up but was speared to the wall with a huge arrow in his shoulder. As Keith walked up to him with the bow he made changing back into the sword he said-
"If you mess with a tauros then you'll get the horns... If you mess with me... you summon my Rage. You might be a mutant that could easily take damage from being thrown at a wall and be stabbed,"
Keith willed the electricity he had stored to form into a circle of electricity with no hole in the middle, of which he held above his head and threw as fast as he could.
"But you can still be killed." Keith finished
Ten feet before it hit Tanner it split into 5 different rings, four went through Tanner's appendage joints, cutting them off completely. The last hit cut off his head. As it rolled, Tanner was able to see the last look Keith had on his face, one of complete hatred and malice as he slowly faded into blackness.
After he killed Tanner, Keith took out the bottle of Total Heal pills and gave one to Kate. She stopped bleeding and was still alive, thankfully. After he gave her the pill thought, Keith blacked out and fell into Ari. Complete exhaustion had taken him when he went into Rage form.
OOC: would a Mega-Evolution sound better or just Rage form?
