There are 39 characters in "Brawl". 14 unlockables and 25 starters. Most of the characters from the second game in the series, which was called "Super Smash Bros. Melee", return (although Mewtwo, Roy, Dr. Mario, Pichu, and Young Link were removed), and a few others are added, including two (Solid Snake and Sonic the Hedgehog) that were in games that Nintendo did not own. The game is best known for the tripping mechanic (fighters will trip at random when running), introducing third party characters, and the smash ball.
