The Heavy Weapons Guy, more commonly known as the Heavy, is a towering hulk of a man hailing from the USSR. He is often considered the face of the game, due to his prominent appearance on box-art, promotional materials, and loading screens. He starred in the very first Meet the Team video, and has appeared in all further movies to date.
The Heavy is the largest and arguably most dangerous class in Team Fortress 2 - boasting the most base health, combined with devastating firepower.
