A famed krogan mercenary  \and bounty hunter, Urdnot Wrex is also one of the last Krogan Battlemasters: rare individuals who combine powerful biotioc abilities with the devastating firepower of advanced weaponry. A long-lived krogan who has had many adventures, Wrex has heard of Commander Shepard on his travels, and respects the Commander as a fellow warrior.


Despite his chosen path of violence and killing for credits, Wrex is deeply concerned with the fate of his people after the genophage, and is one of the few planning for a new krogan future.
