Sergeui Khalifo "Kavin" (a.k.a.) The Sabretooth is a fictional comic book character and an enemy to Wingman. He was in wars and became similar to the "super soldier." However, Dr. Rectal wanted him to become even stronger. With this happening, he infused that of a sabretooth with him, transforming him into a half-man, half-sabretooth. With him much more powerful and agile than Wingman, the Sabretooth has become one of his more powerful foes.
