Sargent Johnson or arbiter?
In a fight or just who do we like more as a character? Obviously Thel would destroy Johnson in a fight, and I think I like him more than Johnson as well. -Yoinking!- love Sgt Johnson though
It's a close one but I'd have to go with the Arbiter. He was the first elite to befriend a human (the Chief no less, whom he later came to respect greatly) and has bulletproof armor.
SGT Johnson he taught me the finer things in life, like "what the ladies like", how to send someone out with the biggest BANG for the ultimate showings of respect, and the old ways of fighting, which involved "sticks and a rock for the whole platoon, and we had to share the rock!". May he rest in peace.
