Lavernius Tucker is an armored simulation trooper paired on the Blue side of the made-up civil war in Blood Gulch- and slowly became an even suitable soldier. Eventually he would come into contact with the alien key (which seconds as a sword or, as Caboose says, "A key but it also unlocks people's deaths).
Tucker would act as a stand-in leader time and time again for the Reds and Blues and show an ability for combat beyond that of most of his peers.
