He may not get as much glory as Jago or Fulgore, but Sabrewulf is as much a staple of the Killer Instinct franchise as any. This poor guy has gone full werewolf, succumbing to his Lycanthropic nature; desperate for a cure, he entered the Killer Instinct tournament hoping for help from UltraTech. Instead of treating his furriness, UltraTech experimented on Sabrewulf, coating his arms with metal and driving him into a vengeful insanity. What a bunch of a-holes.
Sabrewulf is clearly pre-metal-arms in the Xbox One KI, but he definitely seems to be at his most feral. He's completely without projectiles, but to make up for his lack of a long-range game, Sabrewulf is extremely mobile, able to dash and lunge around the screen with lightning quickness. Once he's in your face, Sabrewulf's claws can shred you to pieces, and his crescent-shaped anti-air swipes can juggle you for days. If you're an aggressive player, Sabrewulf will be right up your alley.
