No. Believe it or not, Sawk and Throh aren't version-exclusive. They're just rarer in the corresponding game(Sawk in White and Throh in Black).
Throh is a Fighting type pokemon.
Sawk is found in shaking grasses on routes where throh can be found normally in white and in black throh is found at the same way.
