3. Urdnot Wrex
Wrex? Shepard. Wrex. Ahhh, Shepard. Wrex. *head nod* Shepard.
If you played Mass Effect and weren’t able to save Wrex in the end, and didn’t start over then and there and save him, you’re an ass in my book. That’s right, I just called you an ass. Wrex is a huge part of Mass Effect for me, as I am sure he is for others, as well. If you sacrifice Wrex in the first installment of the series, your Mass Effect 2 and Mass Effect 3 playthroughs will suck. In Mass Effect 2, Tuchanka will be run by some random Krogan you’ve never met before, and I didn’t even bother looking into what Mass Effect 3 would be like without Wrex.
Wrex was infamous for being hard to work with, incredibly aggressive, and kind of a dick. Shepard had the ability to not only calm Wrex down in dire situations, but make him one of his/her best friends. Nothing sends chills down my spine like their reunion on Tuchanka and Wrex screams, “Shepard! My friend!”
As a squad member: Wrex is powerful in both combat and biotics. If I needed someone to carry some weight in my squad, Wrex was my number one choice.
