Wolverine's face contorted into one of shock and rage. "And what's supposed to make me believe that I'm related to you, bub?", he said emphasizing the bub.
"Do me a favor, o brother of mine, scratch me with your claws on the hand."
Wolverine smiled eagerly. "It'll be a pleasure!" He brought down his claws hard on Silverback's hand and watched the blood squirt out in little bursts, occasionally trickling through his fingers.
Silverback gave a smile of provocation. "Is that all you have, Logan? I thought you could do better than that with those things," he pointed to the adamantium claws, "than that! Come on, Logan! Gut me right arm, destroy a vein or two. I won't mind!"
Wolverine did the stranger's bidding happily, not caring much for his cheery attitude. With a quick swipe, blood was speedily rushing from the arm of the intruder Silverback.
"All right, now Logan, stand back and watch the magic!"
Logan stepped back, his claws still ready for any funny business, and watched his so-called brother's show. Silverback touched his arm softly with his hand, right on the bleeding spot, and gave a look of soothing. Suddenly, the slit of blood began to slow down, until nothing was there at all! Then, the skin itself began to patch itself up, regrowing the lost skin.
Next, Silverback brought the same hand onto his wounded one, and the same happened. A soothing look, the stop of flowing blood, and the regrowth of skin. Logan was dumbfounded for the first time in his life. There was no question about it… Silverback had a healing factor!
Logan stepped forward slowly, sheathing his claws. "Y-you have a healing factor?"
Silverback smiled. "Why of course, Logan! How could I not be and still be your brother? But wait, that's not all I have to show you! Now, a demonstrating of mutant power number 2!"
Silverback suddenly began to change form rapidly. He went from a human to something… else. His body became laden with black fur, and his teeth became saber-toothed, white fangs with lethal points on their ends. His eyes went from their normal gray to deadly pools of red blood, the pupils yellow as a cat's. His fingernails grew sharper and longer into claws. His clothes suddenly ripped out from him, with the exception only of his pants, and his entire body was clearly covered in the black, mottled fur that had begun his transformation. His muscles grew larger in both arms and legs, and he grew to eight feet tall from his original six. All was black for him… except for a silver line on his back that ran all the way from his head. The mark of Silverback.
"This," he growled in a voice twice as deep as Greg's, "is Silverback."
"Greg," said Logan quietly, stepping forward, sharing his brother's pain. "We need to talk, Greg."
"Agreed," said the monster that had once been Greg Williams. "Let's go into the house, Logan."
"Not on my life!" shouted the voice of Cyclops, running from the mansion's side. He shot out a bright bolt of red light powerfully at the black creature before him, injuring it in the right arm, the same one that had just been mended.
Silverback gave a roar of pain and charged forward like the animal he had become, his claw raised in fury. He leapt onto the unwary Cyclops ferociously, and swiped the X-man's chest with his claws. Bright red blood trickled down Scott's upper body in a crescent shape.
Cyclops gave a shout and fired an optic beam, sending Silverback backwards into his brother. Cyclops got up speedily and came in fists swinging to the monster, landing a solid left hook before being sent back himself by a powerful punch from Silverback.
Wolverine stood in a panic, not knowing whom he wanted to win: his brother, or his leader. He popped out his claws and jumped into the fray with them. "I always liked a good fight, anyway!" he thought as he kicked his brother and punched his friend.
Cyclops shouted, "Logan, get out of this! You're hurting me too!"
"That's the point, one-eye!" said Wolverine, cutting Scott's leg.
"Then you give me no choice, Logan!"
Cyclops let loose a huge optic blast right at his friend, keeping Silverback away from both. Logan had no time to move away from the shot, and braced himself for the pain. It never came.
The blast was stopped in mid-air, flickering there like so much dead weight. Scott touched his visor as though there was some malfunction, his eyes questioning. Wolverine was the first to understand. "Jeanie."
"You'd better believe it, Logan," said the red-head, stepping right next to Scott. "Scott, what the heck do you think you were doing? Attacking Logan!?!"
"He got me first," Scott whimpered.
"You sound like a 2-year old, Scott Summers! Now, give me an explanation I like, or you'll be sorry," she pointed to her psychic head.
Silverback stepped forward. "This is my fault, miss."
Jean's face took on a look of shock for a minute at the sight of Silverback, but quickly recovered. "O-oh? How so??"
"Your---"
"Husband."
"---husband attacked me when he saw me getting too close to Logan, probably thinking I was an intruder, and I doubt that the sight of Logan's unsheathed claws helped matters, so he came in blasting. Later, Logan decided for reasons unknown to me to jump in."
"But why were you here in the first place!?!"
Silverback underwent a speedy transformation much faster than last time, this one back into Greg. "Oh, that's easy. You see, I'm Logan's brother!"
