Sabretooth is a mutant who possesses razor-sharp fangs and claws, hyper senses, and most notably a rapid healing factor, similar to Wolverine. They are both archenemies and victims of the Cold War supersoldier "Weapon X" programme. While Wolverine has always tried to suppress his inner demons, Sabretooth has lcompletely and totally embraced the beast within. Sabretooth was a henchman of Magneto in the X-Men films.
Sabretooth by Toy Biz is one of the nicer figures produced and his meanness is well captured except I don't know why Toy Biz couldn't just give him boots.
