What is Jacob Black strengths?

Answer 1

Jacob Black is a fun, easy-going teenager. He's laid back and casual about almost everything--except, of course, on the issue of Bella's mortality. He doesn't take too many things seriously. He is very family-oriented, and was raised to respect family, friends, and community. He is extremely loyal. Especially to his friends. He is obsessed with cars. He is very cheerful and optimistic. And, of course, he is absolutely gorgeous. =) For this reason, he can be sort of cocky. But he just so happens to be very sincere as well, which balances out any ego-bloating on his part.

Answer 2

Jacob is the fastest and strongest of the werewolfs. He also is the born "Alpha" of his pack. ** SPOILER ** He does not choose to embrace it until later in the series.
