Garm

Garm is a krogan battlemaster who leads the Blood Pack on Omega. He is described by Garrus as a freak of nature, able to regenerate faster than most krogan, and a coward, relying mostly on his own gang.

He enters into an alliance with Tarak and Jaroth to take down the vigilante Archangel. Garm holds a personal grudge against Archangel, after Archangel had attempted to kill him while he was alone. The next part of the plan was for the trio to overthrow Aria.

Once Shepard helps Archangel, Garm becomes hostile and leads a group of Blood Pack mercenaries in an attempt to kill them but got himself killed in the process instead.

Capabilities
Offensive

Garm is armed with a M-300 Claymore Heavy Shotgun. Garm will enter the room where Archangel is in and engage him. He will also engage Shepard if the Commander is in visual range. Like many krogan battlemasters, Garm can use such biotic powers as Warp, which makes him dangerous at range.

Defensive

Garm has strong armour and a biotic barrier. He also possesses the standard krogan regeneration and the krogan charge.

Trivia

 * If Grunt is present in the shore party when Shepard talks to Garm, the latter kills one of the vorcha to demonstrate "loyalty" and "courage" of his henchmen.
