|This article is about varren in general. For the Mass Effect and Mass Effect 2 enemy, see Varren (enemy).|
Varren are omnivores with a preference for living prey. Originally native to the krogan homeworld of Tuchanka, they are—like most life from Tuchanka—savage, clannish, and consummate survivors. They are pack hunters when vulnerable prey is readily available and become scavengers when outnumbered or outclassed. Their supreme adaptability, vicious demeanor and rapid breeding cycle have made them ubiquitous and dangerous pests on many worlds. Virtually everywhere the krogan have been, varren infestations have followed, wreaking havoc with the native ecology.
The krogan have had a love-hate relationship with varren for millennia, alternately fighting them for territory and embracing them as treasured companions. To this day, krogan—and some other species, including batarians—raise them as beasts of war. A common subgenus of varren has metallic silver scales, leading to the rather unusual nickname 'fishdogs'.
Mass Effect Edit
Feros EditProthean ruins on Feros. Humans, at least, are capable of consuming and drawing sustenance from varren meat. Commander Shepard is asked to kill a rabid alpha varren in order to permit the Zhu's Hope colonists to hunt the remaining varren. Davin Reynolds didn't just see the animals as a convenient larder, either. Apparently varren are so vicious they'll even take on the geth.
Bring Down the Sky Edit
The batarians who attacked Asteroid X57 set packs of "Batarian War Beasts" on the engineers there (not to mention Shepard and the squad). Simon Atwell hated the sight of them, claiming varren don't always wait for someone to be dead before they start eating.
Mass Effect 2 Edit
Varren encountered in 2185 tend to be colored in a brown-striped variety, as opposed to the varren encountered in 2183 that had white underbellies and dark dorsal sides.
Aside from being a common enemy found throughout Shepard's travels, a single varren, Urz, can be found standing patiently next to Ratch on Tuchanka. Shepard is allowed to pet the varren, who responds in a surprisingly tame and almost dog-like manner. Should Shepard give the varren some meat that can be purchased from the trader, the varren will happily follow Shepard around Clan Urdnot's encampment. The trader notes that the varren "finally has someone to follow around". This particular varren is actually a retired champion of the fighting pits and can be wagered upon with a purse of 500 credits.
A sexually transmitted disease known as "scale-itch" that is carried only by varren can be detected aboard the Normandy during a specific dialogue sequence with Mordin Solus; he will be seen at his lab combating the infection and notes that the implications of it are "unpleasant," euphemistically insinuating that someone aboard has been having sexual relations with varren.
Varren is apparently a popular food source, as advertisements of a "Fish Dog Food Factory," which serves varren skewers as well as varren steaks, can be heard on Illium.
Mass Effect 3 Edit
During the Cerberus assault on Sur'Kesh at one point when Shepard opens a door, a varren is seen killing a Cerberus Assault Trooper before being gunned down. A voice is then heard warning against live varren gotten loose.
According to Jack, varren on Thessia can develop biotics due to the amount of element zero in the planet's ecosystem. Their biotic abilities can make varren even more aggressive and short-tempered, which often leads to their abuse and abandonment. Jack adopts one such varren who she names Eezo.
