SABRETOOTH IS A VIOLENT KILLER. HE HAS A LONG HISTORY WITH WOLVERINE. HE HAS IMPLANTS THAT MAKE HIM STRONGER THAN NORMAL, A HYPER HEALING FACTOR, WHICH HELPED HIM SURVIVE A CLAW THROUGH THE BRAIN BY WOLVERINE; AN ADAMANTIUM LACED SKELETON AND CLAWS, AND HIGHTENED SENSES. AT ONE TIME, HE WAS REDUCED TO A INFANT LIKE MENTAL STATE WHILE HE WAS STAYING IN THE X-MANSION, BUT WHEN HE REVIVED, HE TRICKED BOOMER INTO RELEASEING HIM AND INJURED PSYLOCKE. IT TOOK THE WHOLE TEAM TO DEFEAT HIM, AND WHEN THEY DID THEY PLACED A HARNASS ON HIS MOUTH AND CLAWS AND FORCED HIM TO JOIN X-FACTOR. WHEN HE BROKE FREE OF THE HARNASS, HE WENT THROUGH A BLOODY ESCAPE OF HIS X-FACTOR TEAMMATES, AND REJOINED HIS EMPLOYERS, THE HOUND PROGRAM. BUT, THEY CENSORED HIM FOR KILLING INSTEAD OF JUST CAPTURING HIS PREY.
