Mass Effect 2/Grunt

An exceedingly violent krogan, Grunt is sorely lacking in much of the personal sense of honor (or discipline, for that matter) that many of his brethren possess. He lives for the thrill of battle alone and has yet to know defeat. He is not one to have long, introspective chats, he prefers to let his guns and fists do the talking. If you need firepower and little else, Grunt is by and far the best choice.
