Quaritch

Who is Quaritch? Well, one of Pandora's great fears is that she wants to destroy the Na'vis, however you didn't know what Quaritch wanted to do or even that he was the enemy. The reason? ... Well, he was like you, a Na'vi with the same color and height, so you didn't suspect him, that led you to get a certain feeling for him. One of your free afternoons you decided to go look for him and he was giving orders when you heard something you didn't want "Killing the Na'vis is what I want, especially Jake Sully and his crazy and wild wife..., he I have to do with one of them but...I never cared"
