Pudge is a melee character. His primary attribute is strength. The hero is mainly taken as a hardlaner or half-support. Most effective in the mid game.
Abilities like Meat Hook and Dismember make Pudge extremely useful in team fights. Flesh Heap allows him to be a fairly durable character and a good initiator able to frontlane. Rot is a formidable weapon when dominating an opponent, especially when upgraded with Aghanim's Scepter. Aghanim's Shard allows Pudge to save his allies from almost any situation using the Dismember ability.
Pudge was an ordinary artisan butcher. At one point he became immune to most forms of natural decay and became addicted to eating live flesh. Now Pudge is eager to go into any battle only to chow down his enemies’ bodies.
