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 the devastating firepower of his trusty Minigun. This weapon can inflict huge damage at a very high rate of fire, allowing him to mow down opposing babies, cowards, and teeny-men in mere seconds. Being the slowest class in the game, the Heavy's movement speed is his main weakness. Upon revving up or firing his Minigun, his already unimpressive speed drops down to an even lower amount, making him a very easy target for Snipers and Spies. His sluggish speed makes him more dependent on support from Medics and Engineers to keep him actively in the fight. As a result of his burly stature, he also takes 50% less knockback from most damage sources - excluding Sentry Gun bullets.

Aside from decimating entire teams, the Heavy is able to provide further support for his comrades with an often required health boost via his Sandvich, which, when consumed, is capable of healing him to full health. It can also be dropped to provide an instant 50% health boost to his teammates, systematically equal to a medium health kit. However, if the Heavy is not careful, an enemy may pick up the dropped Sandvich for a health boost of their own.
