Krogan Clans
A battle-hardened species rising from nuclear wasteland to galactic infamy.
The krogan are a fictional extraterrestrial humanoid species in the Mass Effect multimedia franchise. Native to Tuchanka, they are depicted as large reptilian bipedal humanoids who thrive on conflict and violence. Once uplifted by the salarians to fight the rachni, their population exploded until the Krogan Rebellions forced the Citadel Council to deploy the genophage. This biological weapon drastically reduced their birth rate to 1 in 1000 viable births, driving the species toward extinction. Today, krogan society is defined by this struggle for survival, with major figures like Urdnot Wrex, Grunt, and Nakmor Drack navigating a galaxy that fears them.

Lore & Background
Thousands of years before the Mass Effect trilogy, the krogan warred over dwindling land on Tuchanka, deploying nuclear weapons until they created a radioactive wasteland. Two thousand years prior to the original trilogy, salarians "culturally uplifted" them with faster-than-light technology to serve as soldiers against the rachni. Within two generations, the krogan defeated the rachni and were granted former rachni worlds. However, their population exploded uncontrollably. They forcefully extended dominion to other planets, founding a colony on the asari world of Lusia and refusing to leave. This sparked the Krogan Rebellions against the Council and Turian Hierarchy. The turians eventually deployed the genophage, forcing surrender. Now reduced to primitive clans on their homeworld, they face slow extinction with only 1 in 1000 births being viable.
In Their Own Story
The krogan central storyline spans most of the original Mass Effect trilogy and is referenced in Mass Effect: Andromeda. It focuses heavily on the genophage and the friction it creates between alien species. Major characters include Urdnot Wrex, Grunt, Urdnot "Eve" Bakara, Nakmor Drack, and Nakmor Kesh. The narrative has received very positive critical reception for its moral complexity. In Mass Effect 3, this arc dominates the opening third of the game, written by senior writer John Dombrow in collaboration with Patrick Weekes. The story explores themes of redemption for a tragic species, referencing influences like the Thraddash from Star Control II regarding nuclear self-destruction and weaponization against an arachnoid race.
Reader's Guide
Krogan are available as playable characters in the multiplayer modes for Mass Effect 3 and Mass Effect: Andromeda. Design-wise, their faces were inspired by wrinkle-faced bats to look alien, while their bodies reference the heavy skin of an Indian rhinoceros. Animation limitations required tweaking; developers increased the mass of their back area to maintain an intimidating silhouette without breaking human animation skeletons, resulting in their characteristic large humps. These humps store fluids and nutrients, allowing survival for extended periods without food or water. Physically, they are over 7 feet tall with thick exoskeletons. Male krogan develop a full crown with large spikes as they age. They possess four testicles and multiple secondary organs acting as backups. Notable figures like Urdnot Wrex serve as Battlemasters, combining biotic abilities with advanced weaponry.
