Martin LaTierri, more commonly known as Sonny, is a character from Grease and a member of the T-Birds. His girlfriend is Marty Maraschino. In the 1978 film by Michael Tucci, in the 2016 live broadcast by Andrew Call
Sonny is the funny smartass T-Bird, as he likes to joke around. He has a crush on Marty - member of the Pink Ladies - but she doesn't seem to reciprocate until the end of the movie.
Sonny is Italian, brash, and "takes no crap from nobody" - except for Principal McGee. He can be a bit of a jerk at times, razzing Rizzo when Kenickie and the T-Birds picked her up at Frenchy's house.
Sonny is a sturdily built young gentleman with curly hair and a cocky smile.
