Chocolate Bar is a character that only appeared in M&Ms commercials. and is one of the few characters to not be a M&M-- the others are Pretzel Guy, Popcorn Guy, the humans, and Caramel Piece Guy. He was voiced by Phil Hartman.
He tries to be romantic with ladies as seen on the 1996 Commercial Chocolate Bar. He might not like Red and Yellow as he was seen in the commercial slapping Yellow while saying "The name's Chocolate Bar". He melted after he sat a couple of minutes. He was also seen on 2012 commercial "Heat" where he tried to once again impress a girl by giving her cocktails, but melted before he could do so.
