Javik is by far my favorite crew member in the third installment, I took him on almost every mission. Legion was my favorite in the second game. Wrex was my favorite in the first.
Javik: In my Cycle, we cleansed food from our teeth with our own biotic abilities.
Wrex: Man, your Cycle sounds like crap.
Legion: We do not comprehend the organic fascination of self-poisoning, auditory damage, and sexually transmitted disease.
