Your most hated main enemy in Tex games?

Cross' interrogation scene made my own body tense and nervous, like I was really there. Few video games have been able to do this to me.
I agree. I was tense for the entire scene.
And let's not forget the closing scenes in Pandora where Cross really exhibited his true nature (his terrifying aggression towards Archie Ellis was a bit unnerving as well).
