Gargantuan Beast

The Gargantuan Beast is a Wendigo variant in Diablo II.

Lore
Gargantuan Beasts are the weakest of all Wendigo sub-species. Extremely territorial, these creatures attack anything they see as a threat to their power...which is pretty much anything they encounter.

In-game
Gargantuan Beasts are the first type of Wendigo that can be encountered in the first act of Diablo II, in the Den of Evil (no uniques) and in the Cold Plains. While not as common as most other foes, they are easily-noticed by their giant size and occasional grunting.

Trivia

 * Gargantuan Beast may be a reference to the book Gargantua written in the 16th century about a giant.
