He's a rather brilliant individual. He graduated top of his class in all of his studies and second of his graduation class in Migrant Fleet Marine Training. He can field strip a weapon and put it back together in under 120 seconds, which considering he only has three fingers and is a Quarian, that's pretty fast. He's pretty open minded and is willing to try just about anything, especially if it's food, he absolutely loves food. To be honest he'd eat human food if it wouldn't kill him! Other than that he's pretty easy to make friends with, laid back and loves to play video games!
